5900x edc limit reddit 4ghz in Cinebench R23 with 22223 points in Multicores I start off with. 1GHz with a 100% single thread load in older games and 4. Your curve optimizer values your gonna have to find yourself as each chip is super unique for optimized values. Then I tweaked TDC until it showed about 96% usage under load during cinebench and then tweaked EDC. 3 with temps at 82. The concept of the 5800X made sense due to not having inter-CCX latency, which "supposedly" made gaming better. For almost every other board need to increase EDC limit to 200~240,etc in order to gain pbo2(CO) performance. 1V max and the temperature goes down aswell by a lot (I get up to 77° in games, all core boost is up to 4. CB23 scores seem to be linearly linked to TDC and EDC - especially EDC. I am looking for some advice and guidance on how i can best overclock my Ryzen 9 5900x. idle boost spikes. Thanks for the Info though! I just rechecked Der8auer video on 5900X OC from when it came out and he just sets the 3 values and the CPU goes as high as it can within these limits. Hello, I recently switched to a new 5900x on my TUF GAMING X570-PLUS (WI-FI), I replaced my previous 3900x always left at default settings. Am pretty sure it edc though as my 6 core goes up to 110A edc. Si j'augmentais l'EDC, cette fréquence diminuerait continuellement, si je descendais en dessous de 110, elle commencerait également à baisser. 4 Amps on the +12V rail. Extreme loads like Linpack benefit from even more power and 145/190 was much better than 130 My 5900x gets 22,200'ish in R23 but that's CO -30 all cores besides 2/5 which are the best cores which are -10 and PBO +25. I was running into this problem with my Ryzen 2700X but it would just downclock itself instead of BSOD. Asus x570-I ITX - Bios 4204 with AMD AM4 AGESA V2 PI 1. The 5900X was the pinnacle, the 5600X the budget. Personally, I've seen better cinebench scores (and temps) on my 5900x (w/ Arctic LF II 360) when I set the TDC/EDC limits manually instead of just letting the cpu pull whatever it wants. The 5950X is so constrained by the default power limit that it'll probably still hit the limit under multi-threaded load even with a negative curve offset, it'll just do so at a higher clock speed. If your motherboard can handle it, there no harm in going for 200 edc/tdc. Certain benches, like GB5, Y-cruncher, etc, prefer higher TDC and EDC, but even in those benches setting 230A EDC on a 5950x is ridiculous, and if one is gonna attempt that, then, that one better have under 10C IDLE temps. If I do a multi cbr20 run it might hit 80 if my room is warm but thats still within safe limits and it doesn't run at that temp all the time. So I thought what about if I keep power limits on "Auto" but set a PBO Temp limit. Loaded "PBO Limits: Disabled" which uses the default CPU parameters for PPT, TDC, EDC. Setting motherboard limit (crazy high 500A or so and 1000W) scores even lower than stock. This is your PBO settings priority - what you're aiming at first: PBO Curve > PBO Limits > PBO Boost Override > RAM OC. Now my x470 board lowering the power limits results in lower clocks and performance as expected. I'm currently running it with PBO2 negative scaling of 5 on preferred cores, 10 on non-preferred cores and a limit of 140W PPT, 100A TDC and 125A EDC. 4. EDC is ALWAYS higher than TDC, by definition. Increasing TDC and EDC to 150 and 200 gets me over 28000, but at the cost of much higher temperature (85-90°C). I think that is the culprit why can't i go higher than 4. It is a weird issue with most x570 boards. 310] CCX0 Ratio [47. PPT (W) 200W is enough for 5600, 5800 and maybe 5900X SKUs. The AMD default for the 5900X seems to be : PPT 142W, TDC 95A, EDC 140Amps The stock 5900X has only 142W power limit and 95A amperage limit which imo is way too conservative. TDC is rising between 33% to 100% for 1 to 8 threads, then stays at 100%. 375V. 125. 1. These values are during on cinibench. I noted down the parameters, went to the BIOS, set Boost to 150MHz and Curve Optimizer to -20 After that I set the PPT to 200 and kept bumping the TDC and EDC up by 10 until I reached my target 80c max on CB20. Ryzen 5900X MSI B550M Mortar Wifi Kraken X63 with a push/pull config (front) + 2 case fans on exhaust (top/back) 3080 FE 64 GB DDR4-3600 CL16 Was quite shocked with the idle temps on desktop (~60º) coming from Intel (~30º). I also have a Stix x470F and a 5900x. with these settings and a vented panel I'm getting up to 85 C peaks (running the PC all day with tons of different workloads). Another note: the "EDC bug" traditionally refers to using 1 so that your EDC is always >100% which means the boost algorithm is effectively ignoring it based on my 3900x experience. Those limits are the same for 5900 and 5950? For PBO would you I was experimenting with the PBO limits of my 5900x and i noticed i was getting worse clock speeds and r23 scores when my edc is above 100. For pbo don't use boost override or llc. PBO Scalar: Auto. Highest PPT/TDC/EDC limits are not necessarily the best. CB23 score is about 11000 that impossible in 67W limit. I set all 3 PPT, TDC and EDC to 999 and nothing changed on my Crosshair VII Hero. Get the Reddit app Scan this QR code to download the app now Zen 3 (5900x) and EDC vs TDC As of finding EDC/TDCbasically I set limits to MB and found the At stock my 5900x scores ~20500 MC in cinebench R23 and ~11600 in Time Spy. For example I run a 203PPT limit and get around the same frequency and scores. 3c that will uncap your edc limit. 31134 Sure, I’ll explain it. Manual oc disable pbo automatically. As of finding EDC/TDCbasically I set limits to MB and found the max EDC/TDC, set those manual and now I'm working my way down by 10A increments while running tests per down bump. My settings in AMD overclocking submenu with a 5900x: 100mhz pbo limit, 200 wattage, 200 tdc and 180 edc. Or you can put them lower to reduce the heat (and a little performance). EDIT: Actually, I made a mistake. 6-4. It seems like a 5900x can draw more power, 250w+ in some cases, so I think it may be safe to increase EDC until the CPU is not hitting the EDC limit, at which point you will have to increase voltage to draw more power. We would like to show you a description here but the site won’t allow us. Watts (PPT) and max amps when hot (TDC) are the boundries. 90c with noctua paste. Reducing PPT/TDC/EDC will reduce the heat output. I was not able yet to look into this in more detail, but with stock settings on these i am around the 60°C mark with 1. Any ideas? Just some random thoughts: You could play around with PBO limits. I set back to my normal values with 120A EDC and got around 350+ GB/s. My board is a measly B550M Tuf gaming, and it sets EDC to 180A. My 5900x also just running at 4. 0. That's definitely reasonable. PPT Limit 150 (you will want more - search reddit/google for suggestions) TDC Limit 160 (same as above) EDC Limit 100 (This is the one that fine tunes your curve optimizer after you find the best curve optimizer numbers. In my case 5900x/AorusMaster/NH-D15 went from stock 21500 cinebench score with stock limits to 22500-23000 with manual limit (125/150/175 if you ask). This has given me very good performance. So adjusting the TDC down probably won't help if it isn't peaking there. 180A EDC is set and the CPU does exactly that while hitting something like 70C. Most likely, your PBO limits set by your motherboard are too aggressive and allowing too much power, resulting in high temps. I would say start around stock settings and go from there. 5900x的tdc阈值大约在108左右；5800x为60左右；tdc的设置不能低于这个数值，建议比edc低20即可。 5900x edc参考值：170-200. These correspond to "motherboard limits" This has been how the system has been running happily for about a m I set PBO limits to motherboard & got the following limits: PPT: 190W TDC:128A EDC:215A. Get the Reddit app Scan this QR code to download the app now PPT/EDC/TDC for a ryzen 5900x . seems to be stable at -5 as well. EDC "bug" causes baseline VID limit to be brought down by default, if EDC value set in BIOS is different from default value for your CPU. You'll be fine with the d15. stable at -5 but temp was too high for my taste. Curve Optimiser: All cores -10. PBO Limits: Manual PPT: 100W TDC: 70A EDC: 100A Max CPU Boost Clock Overdrive: +200 Platform Thermal Throttle Limit: 90 Then open HWInfo (Sensors only), go to section "CPU [#0]: AMD Ryzen 5 5600X: Enhanced" and look for CPU PPT, TDC, EDC. CPU temp 82 degree. Tdie: 85°C I expect this helps. I think auto sets PPT TDC and EDC limits to 500 200 and 220 respectively as indicated by Ryzen Master. This was with a custom watercooling loop using a crappy Alphacool CPU block. 55 GHz) when doing all-core tasks in GNU/Linux. Here's what I have: PPT: 300 TDC: 500 EDC: 300 SOC TDC: 300 SOC EDC: 300 I'm also using x10 scalar, for what that's worth, and a manual thermal limit of 90c. EDC limit of 128 seems low. I have three cores in the -teens (-12, 14, and -16) and the rest are two at -25, one at -26, one as -27, one at -29, and four at -30. All core Eco-mode is just a macro, that sets the PPT, TDC and EDC limits to match the limits used in a lower socket infrastructure class. 45W (AM4 infrastructure H) PPT = 60W, TDC = 45A, EDC = 65A Mode 2 i. It only reach 4. 7 without realising they'll effectively be stuck with the default EDC limit for their 65W TDP processor. 6b 3080 FE 16GB F4-3600C15-8GTZ I quicky checked my limits on PBO and indeed these were set to motherboard limits. 6 at 78,5c CPU-Z Single: 703. Try manual and you'll get higher limits. Also, why would I buy a 105W TDP CPU to limit it to 65W? For 10% performance, I would snatch the 65W one and save money for other components. The 5900x should perform best at some lower value than this but as you saw in my post it depends on the workload. Do not touch stock values (PPT/TDC/EDC) for now, those are your motherboard limits. For the record, my own PBO2/CO settings are fairly close to as good as my sample of the 5900x will do, and those PPT/TDC/EDC are what I arrived at, with scalar 1x and Boost at +150Mhz. Max CPU Boost Clock Override: 125. 5c CPU-Z Multi: 13164. 7GHZ - but in Cinebench my temperature barely reaches 68°). EDC Limit 150. The chip holds 4. Where do I find these default limits in ryzen master for my 5900x? Thanks When checking sensors I've noticed my edc is straight up capped on 90A as it is on stock limits even tho i've disabled pbo. EDC is locked to 210A as standard. 65W (AM4 infrastructure B) PPT = 87W, TDC = 60A, EDC = 90A I don't even have a AIO coupled with my 5900X, instead I'm using the NH-D15S, but even with raised PBO limits my CPU is at 85 degrees or so in a Fractal Meshify C with two 140mm Noctua fans at the front. I'm running B550-MSI-Tomahawk - 64gb ADATA XPG ram - 6750xt, with a EVGA 650gt. Dude we have the same cooler, try mine. Which of those three limits has the most impact on temps and considering my other settings above, how Jun 30, 2021 · I put a Ryzen 9 5900x in a shoebox ITX case. . Platform Thermal Throttle Limit: Auto. 275v. Best best is, if you have sufficient cooling just punch in 300/300/EDC because you want the chip to only throttle based on physical limits, not power limits. 6. I have a open loop cooling and can run an EDC limit of around 203A, and letting TDC and PPT at 255. My Cinebench R20 scores are typically 8800-8900, I haven't run R23. At those settings, the CPU gets to 80%-90% of the EDC limit when running stress tests such as Core Cycler and OCCT. When I build the system first time I had not saw such odd values before BIOS update, I suppose. Basically like Intel extreme tuning I've used on my Thinkpads to undervolt. On MSI MPG B550 GAMING CARBON WIFI with 250A+ motherboard limit Cinebench R20 gives more than 9000 poins. Get the Reddit app Scan this QR code to download the app now 168A EDC limit? (5900x, aorus b450) Revert to agesa 1. If you said it was set to 200 (as a limit) and you saw it drawing 95% of that then you should have seen it drawing around 190W during those Cinebench runs. I figured numbers would be different since doing per core, surely they all wouldn’t take -30 right? Regarding the EDC limit i've done excessive tests when i had the 3950x; setting it to 0 would give you full unlocked performance, the next best performing value was about 230A in cinebench at least. You have set the EDC limit to 0 which prevents the CPU from working properly. I'm currently using 5900X, but this guide will be suitable for the other 5000 series cpus nevertheless. 2. Latest bios, cooler is a NH-D15. I've running tests on EDC first, I guess will set it at the best mix of ghz/points/temp and will move to TDC after. Under Curve Optimiser, I seem to be limited by EDC with 'motherboard' set as the option for limits. Max frequency: auto On this I wouldn’t hit my edc or TDC limits. 1 with too high voltage and insta Apr 30, 2021 · TDC is the limit of current that motherboards use in thermally-constrained circumstances (or the maximum sustained current), EDC is limit of current for peaks (i. I had to limit my EDC to 140 to make my 5800x and 5900x to run its full potential. Should I try an EDC of 90? This was my previous benchmarking of the 50, 100 and 200 MHz boost. Actually limiting EDC to 165 instead of 190, 210, or higher that a lot of people set without testing is still safer than setting to motherboard limits (which is 190 for my board). To be better help you, download Ryzen Master from AMD and report back your PPT, TDC, and EDC limits as reported by Ryzen Master under the Advanced view. Dans Cinebench, il atteindrait une vitesse totale de 4,76 GHz. Of the three, PPT, EDC, and TDC, the two limits you are most likely to see pegged are PPT or EDC, and ideally you want it pegged on EDC. 5900x I’ve seen like to be around the 170 edc level for max scores but some might want more or less peak current Please note the CPU temperature decrease as I increase the current limit which correspond to the performance drop. black with the AM4 offset brackets and do a 30-minute Cinebench r23 mc throttle test no overclocking just enabled PBO and the limits PPT 195 EDC 140 TDC 130 no undervolting no curve optimizer LLC was left on auto mind you this is on a 6 plus year old motherboard the Asus I believe this means we arent clock stretching. Setup 5900X B0 Stepping early unit, not first week tho. which basically means it shoots above 5. Is there anyway to increase EDC limit without enabling PBO, or is it just stuck on stock limits when not using PBO. Dec 13, 2020 · The most important step I took to limit my temperatures is to properly set PPT, TDC and EDC. Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more.

First find thermal balance with the limits, then find optimized curve, then optimize curve using boost override (in steps), then finally balance limits again with new curve settings for best results. 3c. 2. If you see in Ryzen master, during the benchmarks, that your 5900x is using up 25% of your max PPT limit, and your PPT limit is 1000w, then you can set your PPT to 250w instead. Feb 17, 2021 · System Name: PC on since March 2025, upgraded from 5900X: Processor: Ryzen 7 9700X (March 2025), 140W PPT limit, 85C temp limit, CO -25, +100MHz (up to 5. Jul 26, 2022 · EDC Limit [A] [160] No changes in scores in CB20 but not so much changes in temps too. Having PBO off or on, and PPT/TDC/EDC limits set to motherboard or auto makes me hit 90C on all tests. EDC 120 in Ryzen master hit 4625Mhz when limit was default 90c. My TDC is always about the same as core current. I've tried PBO and the EDC bug with my 3900x and am not comfortable with the voltages it puts out even with a - offset. Boost: 100Mhz Curve O. 5Ghz, despite Ryzen Master reporting that a max clock achievable is 5. 185 PPT, 125 TDC, 170 EDC is generally accepted to be the best/most reliable combination for the 5900X. Only the extreme test variants can use more than 16 threads in the physics test, the 5900X offers 24. You can use Curve Optimizer in the Advanced tab, or set a slight negative voltage offset to undervolt. Is there a limit for PPT TDC EDC? If i leave it at unlocked PPT is 395, 160A TDC and 190A EDC Decided to take my Arctic Liquid Freezer II 360 A-RGB Rev 4 with the offset brackets off and test the Noctua NH-D15 Chromax. You can use ryzen master to see what is limiting you and bump that up a bit each time if you dont want to just jump forward. Make sure Fmax is off. 15Ghz. With this at 105 I lost about 25mhz, and at 110 to 120 lost between 25 to 50mhz so it is part of the fine tuning you can do The selcted PPT / TDC / EDC limits in BIOS. 8 43 votes, 35 comments. Always hitting EDC. 3c R23 Single: 1653 at 76. PBO Limits: [Motherboard] (PPT= 720 W, TDC= 360 A, EDC= 215 A) The CPU will only reach the EDC limit with these settings, this is the default for my board. You should probably also tweak the voltages a bit with Curve optimizer, put a negative offset on each core. max temp 70C with cinebench & 80 with OCCT avx extreme & Large. 6 The thing is if I set the power limits to "Auto" I get R23 score of 29840 but with temp at 91. 5900x on a Crosshair 8 Please keep in mind that settings will vary from motherboard to motherboard and CPUs. When I load test, as soon as the CPU hits the EDC of 215A, the boost locks at around 4. Given we're talking about 5900x, using 230A EDC becomes even more ridiculous. Get the Reddit app Scan this QR code to download the app now Adjusting ppt, edc, tdc limits for Ryzen 9 . This is my configuration: Ryzen 9 5900x rev. The EDC motherboard limit is 190A. I can't find a way to change temp limit in ryzen master, I can only set PPT, TDC and EDC limits What is a 2ccd motherboard and what does it mean to set limits to this option? Next, he states that alternatively, you can assign manual PBO limits for PPT, EDC, and TDC. 46v just to get higher boosts. The top scorers seem to use very fast memory >4000 MHz - good luck getting that stable enough for benchmarking. Save it, and get back to Windows. I set to PBO Limits to "Motherboard" or 999 all values improved the bandwidth to 600+ GB/s. Power limits PPT: 220 TDC: 160 EDC: 155 ScoreR23 Multi: 28411 at 78. Boost performance is very temperature sensitive, keep that in mind when comparing your own scores. My limits are 200 ppt 130 edc and 120 tdc with +150 max boost oc and curve optimizer tuned per core. I got the best performance with 130/170 on TDC/EDC for Cinebench. And that you can set default limits found in Ryzen Master. Here is a what I did with 5900x to get to run 4. Curve oprmizer all core - 30. I was seeing 1. J'ai obtenu mes meilleures performances du processeur lorsqu'il était à 110. Limits Ryzen Master usefulness if values don't translate the same. I found 300/200/200 to be pretty solid for this MSI board. 35GHZ in R20/23 - But I notice that during a Cinebench run my voltage drastically lowers itself to like 1. It just sits at 90c flat, TDC limit is always 95A. 5-4. With PBO and curve optimizer my 5950x's best core can sustain 4. Adjusting EDC to around 140 slightly improves scores, suggesting a possible anomaly with EDC settings. And the all the 3 limites: PPT EDC and Thermal are nowhere close to the limit at 300A, 999A setting: EDC: Default(200A). 3. So as the title say, I wonder what CPU score do you have with your 5900X and 3DMark CPU ? Edit : I got now 14 588. Also, if you're on a newer BIOS/AGESA then raising EDC above the stock 140 does something weird with the algorithm and specifically really hurts your single core score. 8. I keep hearing that the way to do this is by using PBO and some new technique called Curve Optimizer. First I tweaked PPT, TDC, and EDC with PBO enabled. Yea, you can limit the power draw by lowering the PPT/TDC/EDC limits in the PBO overclocking section. Your CPU may or may not handle the same settings. The best so far for me has been: Fmax: Disabled PBO limits: Disabled. I would start with setting PPT to the max of what the 5900x can handle and adjusting EDC and TDC afterwards. VRM-B2 Thats about the same settings and score I get with my 5900X with CO, and at least for the AGESA version that the board its on has if I raise the limits the scores go downhill. TDC Limit: 200. Sep 29, 2021 · Really extending the EDC and PPT limits don't do a great deal because of temps. 00] Dynamic OC Switcher [Enabled] Current Threshold to Switch to OC Mode [90] Calibrated Temperature Threshold to switch back [80] PBO Limits [Manual] PPT Limit [W] [200] TDC Limit [A] [140] EDC Limit [A] [160 I have PBO enabled (throttle and scalar to AUTO, motherboard limit, +200Mhz) and curve optimizer set. then when i set the PBO limits to disable: PPT: 142W TDC:95A EDC:140A. 65GHz) I recently started looking into PBO2 and Curve Optimizer for the 5900X I got recently. I'm using a 5800x if it matters, and not going above base oc of 4. Black with the 7mm offset brackets to keep it cooler. 5800x edc参考值：140-170. This should be a good starting point as the values to pick for PPT, TDC and EDC. 45GHz stable in Cinebench r23, and even higher (4. My 5900x does around 4. For my 5600X VID limit value goes down from 1. Cooler is Corsair H100i Platinum (240 one) and temperature is around 76° during tests on Cinebench R23. Max temp of 89C. PPT Limit: 200. you want to limit your value of the edc aka temps then your boost will go up. But since you're also running a sff system my suggestion is to let the limits at stock, use curve optimizer to undervolt and squeeze out last bit of performance, and tweak your fan curve to keep constant below 75C, and really ramp up hard above 85C. Your edc and tdc will determine the resulting ppt so start tuning edc for boost and then tdc for temps. Several mental breakdown from inconsistent crashes and restart that I don't want to RMA my 5900x. Mode 1 i. Intro: PBO PPT/TDC/EDC: 95W/85A/120A. Edit: Still doesn't answer why EDC 120 on Ryzen master / PBO limit = motherboard gives entirely different results than defining in BIOS. iirc I have 155/135/120 PPT,EDC,TDC using a Cryorig air cooler. All core boost frequency 4. Then max amps when spike (EDC) (EDC) can effectively stomp on the gas pedal IF wattage limit (PPT) and temperature headroom (TDC) allow. I know that manually overclocking these AMD chips is not worth the effort. Get the Reddit app Scan this QR code to download the app now 5900X with PBO 200, 130,160 (later on 200, 130, 110) TDC and EDC limits to control heat when i can say if you do end up shooting for the moon the cpu will degrade fast within a yr. One thing I've found, at least with my 5900X, is that undervolt-related instability happens at lower/idle clock speeds more often I have a 5900x and I keep PBO disabled since the stock performance is more than fine for my workloads, but was curious to see what PBO potential it has, and with PBO set to advanced and PPT/TDC/EDC set to Motherboard (500/200/280), in Cinebench R20 i get multi core all clocks around 4. 65GHz in all core loads. it should get you to roughly 4. Your CPU is perfectly fine at 90°C fwiw, so there's no need to even worry about it. 1% and 1% low. But I never noticed anything. My sweet spot at the moment is 185 PPT, 125 TDC and 170 EDC, which nets me around 4500Mhz all core on Cinebench. TDC and EDC seem to sensitively effect performance, too high or too low causing problems - but PPT does not seem to have this effect if TDC and/or EDC are limiting, so i just run 250 PPT. However on Asrock B550 taichi (at least mine) I set POB advanced and set it manual instead of MB. Enabling PBO can raise those values to the maximum supported by the motherboard BIOS. 00] CCX0 Ratio [46. CTR on the other hand, I have it at 4425/4425/4250/4250 @ 1. On the other hand, raised PPT limit is usually used to alleviate power limits on heavy multithreaded workloads, especially apparent in high core count processors When you are benchmarking your cpu, see in Ryzen master, what percentage your 5900x is using up for 1000w PPT, 600 TDC, and 155 EDC. PPT and TDC are still low, however. First, manual setting I used was these within Precision Boost Overdrive: All Cores to -25 PPT Limit: 165 TDC Limit: 115 EDC Limit: 150 Pbo: advanced Pbo limit: mobo Scaler: auto Curve: -20 all cores Override +200 Thermal limit auto Seen in ryzen master: PPT: 1000 TDC: 114 EDC: 168 Results in cinebench multi: Score: 11752 - 11830 Temp: ~67C Clock: ~4560Mhz (all cores) Peak voltage: 1. I also seem to get better all core performance when I lowered my edc limit to 180 compared to the 210 I'd get when going with my motherboard limits. C23 score 22093 EDC: 300A. : -20 on all cores My PPT hovers around 88-90, TDC at 48, EDC at 81. If your main goal is to reduce the temperature of your CPU, stop messing about with PPT, EDC, TDC and anything else, and simply set "Platform Thermal Throttle Limit" to Manual and set whatever temperature you want to limit it to. View community ranking In the Top 1% of largest communities on Reddit. I used two of the settings; the one I manually set up and the one I used Ryzen Master's Curve Optimizer. I could change PPT and TDC to whatever, but if my EDC exceeds 130A (5950x) my single core tanks, but the higher my EDC is the better my multicore scores. 7. The 5900x is rated at 105W, but easily draws 140W if you allow it. Too high numbers will pump too much voltage for no reason. starting with PPT 300, EDC 150, TDC 150 seems like a good starting point. When this "bug" triggers, during boot process CPU gets new VID limit set up, which is lower than baseline one is. I have been reading some posts where people seem to get very good CB23 scores with low(ish) values for TDC and EDC, and I can't understand how. I used to just whack PBO on "enabled" in the bios, which resulted in PPT 500, TDC 210, EDC 280. My X570E has the same behavior with PBO Limits = Mainboard. Going just 1A above the default EDC limit triggers the bug, and it looks like it reduces the voltage by about 75-100mV for both single core and multi core loads. My Crosshair VIII sets them to 395, 255, 200 for my 5900x. After you find your PBO limits, I'd think about whether you want to prioritize single core or all core boost before tuning your CO. Cinebench R20 with EDC 190A is only 8500 poins. If your on new agesa/bios updates keep your edc at 130 or it will bug out and lower performance. Pay attention to hwinfo effective core clocks. This information can be read on page 353 of the "Processor Programming Reference" PPR for short. 55 all core but it won't drop which make my result very consistent and you don't have to worry about all core clock in gaming, game does use multicores but not much (except for games like CIV) so it probably won't hit your edc limit, single core performance PBO Scalar: Set at 1, with a temperature limit of 90°C. assuming it's the same as my B550 taichi, the "motherboard" power limits are pretty low. For me, the optimal 5900x numbers on noctua d15 are 220ppt, 165 TDC (doesn't seem to matter much), and 135A EDC. Yeah curve optimizer is a long process, can take a week of regular usage and then you crash randomly, usually it's the second ccd that takes largest offset on 5900x so it's likely true. Edit: I wrongly thought that this bug is what affected the clock speed on my 5800x3d in agesa 1. This Your power limit is killing you put that shit to no limit and just watch thermals same with EDC limit put it to no limit. Additionally, EDC is always higher than TDC, often a lot higher - so an EDC limit lower than that of TDC will kick in far sooner. I actually got my highest CPU-Z 1T scores when just using PBO in 95W eco mode on a 5950x, no core optimizer and all that. Turning EDC down from 154 to 125 helped immensely for example, which keeping it around 30-35 away from TDC. Negative 20 18 18 21 19 23 30 30 30 30 30 30 My results: CB20 Multicore: 9118 CB20 single core: 633 Max. For people who want to go further, you should play with TDC and EDC combo for higher results, even a small variation can be enough to squeeze a bit more performance. O have another PC on 5900X, and I see that EDC in 5900X is about 15-20Amps in idle. You should consider trying some undervolting with CO since your already getting really good performance without offsets, part of that is the AIO because Zen 3 soft The default limits for 105W CPUs: 142W PPT, 90A TDC, 140A EDC. So for me it was about finding a balance with the EDC limit. ini. 由于cpu体质差异、主板型号差异、bios差异，实际表现可能会有不同，以上数值仅供参考。 Actually drawing 200 TDC sounds impossible, i've never seen anything hit 170. The L3 cache AIDA64 results was a BIOS bug that was fixed with AGESA 1. 65 to 73c on cpu 70c on core RTX 3090 strix / 88 to 90 on memory temperature junction Core VID [1. In the same place look for simple switch to turn it on/off, and set it to Advanced, with PBO Limits Manual. As a result the workloads which rely on EDC are throttling badly, while workloads with steady current (cinebench) are not. Btw I was running a MSI board as well a X470. Experimenting with 240/200/200, or even 240/140/140 seems to yeild little to no difference. Your edc is really the limit to follow - the max is somewhere around the motherboard limits that can be set in the PBO menu. I have pbo on with my 5900x, set to mobo limits (dark hero) and only 1 fan on my d15 and during gaming it peaks at 60. Edit: Just don't stretch the PPT/EDC/TDC limits to far, it's not worth it better to balance this together with curve and boost override. Go to ryzen master profile and 'Copy Current', then lower EDC by 5A steps and apply live while watching 'effective clocks'. For increased aggressiveness try dialing back EDC to 120 I'm currently using an EDC of 120, TDC of 70 and PPT of 120. I see good temperatures, scores but odd monitoring. For my 5900x, my final limits were 200/120/145. Zen 3 frequenzy / temperature scaling - 5900X This motherboard is not enough for the 5900x. 4 vid equates to about 130 watts per CCD which shouldn't be coolable with ambient solutions. PPT is the power drawn from the socket, TDC is sustained current limit drawn from the VRM, and EDC is the peak current limit drawn from the VRM. 200a TDC @ 1. 15V under cinebench loads. PBO: Advanced PBO Limits: Manual PPT / TDC / EDC limit: 225, 150, 190 PBO Scalar: Manual 1X Max CPU Boost Clock Overdrive: 100 Mhz Platform thermal throttle limit: Auto Curve Optimizer: By Core. So I would say test both and then adjust from there. Sur mon 5900x, ça aimait moins l'edc. Benchmark scores: Single-thread Scores: CPU-Z at 660, CNB23 at 1590, and Timespy CPU test around 14k, previously reaching 16k. EDC limit hit. For instance, my 5900X is sitting under an Alphacool Eisbaer 420, and depending on the limits I set, the max temp will be: Under ECO limits (the chad mode) - max 60C Under normal limits - max 80C Under motherboard limits - max 90C I ended up setting PPT, TDC, EDC to 185, 125, 170 respectively, Ps your power limit is very reasonable, good job finding those values. SFX 700W PSU capable of supplying 58. With stock PBO limits, mine Hi, I never overclocked before, but it appears now I am an underclocker due to this shitty 5900x chip I have. I used cinebench R23 as a benchmark and set PPT to a high limit where it never saw more than 89% usage. But seeing as you are running 75C+ now, I doubt you will be able to increase voltage by a lot before thermal throttling at 95C. It sets a PPT to 1000W, TDC: 160 EDC: 190 The results is my 5900X going to 81c during CB20 even under liquid metal. The "High Temperature Integer Threshold" is reset at 70c for AMD processor family 19h, the same as family 17h. rn its set like this: PPT: 170 TDC: 140 EDC: 100 All cores on -20 in CO (probably not stable, i just want to find good PBO settings before i fine tune in CO) Temp is 76 C Need some help with my 5900X + Tomahawk X570 combo. For me personally, it was a lower EDC with my PBO limits. Curve optimizer on per core setup put all my cores on -30. My 5800x got neutered by “motherboard” limits where as my 5900x and 5600x both were awesome at motherboard limits. did was enable pbo and did a manual limit TDC 130 EDC 150 PPT 180 with no CO scored Seems like now it stays at 86A EDC / 135W PPT and slightly lower clockspeed. 55Ghz anymore. Previously I had a 5900X that got retired into a rack server - but it wasn't a good clocker. However, I have no problem with 0. That was pretty straight. e. You set EDC and TDC backwards, actually lowering EDC below the stock value. Lowering the power limits results in higher boosts. Some motherboards do crank those values really high when set to motherboard limits in the bios. 4ghz with ppt 200/edc170/tdc 130 during extended r23 all core Anyone have a base mark to set a 5900x up in bios? Running an asus x570e mobo. So thats why my 5800x3d can't reach 4. 9-5. The default limits are 142W, 95A, and 140A, respectively. You can just put the EDC, PPT etc to motherboard, because it is the cpu that asks for the amount of power it wants, not the socket force feeding it. Try 250/170/130 - PPT/EDC/TDC. Here's a little on why. Might go back to 1. For Pbo limits just go by cinebench, max out ppt and tdc and test it, increase by 10 edc and follow the scores, at some point they lower again,every chip is a little different, other benches loves higher edc due to cache friendly,cinebench not, also single core loves a little edc increase. "ECO mode" is a preset of this you could try out. It is quite ridiculous. I assumed this would result in a possible boost up to 4,625mhz per core as an initial test from the existing 4,500 limit. Now we must configure CoreCycler to effectively test stability. 5950X, when configured correctly, will be (and already is) more power efficient than all other CPUs, short of the Threadrippers and Epycs. EDC 140A, PPT 142W. but the settings i had were 195, 135, 135. My best scores were with 170/130 for tdc/edc but I hit the limit of my cooler before anything else. According to MSI this board's max is TDC 200A and EDC 240A with a decent sized heatsink on the VRMs. But I found out the EDC limit was lowered in a privios gigabyte bios. I'm running 300/60/100 with per core offset + vcore offset and got 11900 cb23. burst conditions). Posting just in case there are other people like me who update to 1. Hopefully Asrock will provide the new AGESA versions for my specific x570 motherboard but thats for another day. My values are the following: PPT 185 TDC 125 EDC 170 Max Boost +200 MHz (max I could input) Thermal Throttle Limit 255 Curve Optimizer -20 all cores Scalar ×10 We would like to show you a description here but the site won’t allow us. I'm switching to a new home so I haven't much time to play around with overclock and watching video about that, so I need your help for starting. Raising the power limits increases performance as long as cooling is capable. Open its directory, and open the file config. This resulted in certain scores and low temp. Curve Optimizer: -15 offset all cores. Still 560+ GB/s. In the cpu voltage option I choose offset - 0. 46 gHz. Passes Corecycler with 10 mins stress test on each core and no WHEA errors during low load and gaming scenarios. Quickly wrapped my head around PBO2 and PPT/EDC/TDC thanks to this community ️ and started doing some testing. Bios settings Pbo manual Ppt: 220 Tdc: 140 Edc: 160 Scalar: auto CO: -20 all core (played around with per core and not worth the hassle as benchmarks are about the same). Ryzen 9 5900x & NH-D15 = High Temperature. PPT 195 TDC 130 EDC 140 no curve optimizer or undervolting my scaler was left on auto all I did was found my PBO2 limits cooling my CPU Noctua NH-D15 Chromax. 1 but mind you, you will get the issue that plagues 5000. 45V to 1. If I increase the limits like EDC even by a little, it starts downclocking to 4850, I think thats just AGESA on these EDC bugged BIOSes. true. qgtshr jnkz pjeq stdqt lyiro uyhbcte yuwkg ertwa hnruz fyzc
