5900x edc limit reddit. 5900x on an Aorus x570 Master, PBO set to enabled.
5900x edc limit reddit I was running into this problem with my Ryzen 2700X but it would just downclock itself instead of BSOD. Slowly 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. Extreme loads like Linpack benefit from even more power and 145/190 was much better than 130 i can say if you do end up shooting for the moon the cpu will degrade fast within a yr. Is this really the max limit on the mag x570 or is EDC just not recording correctly. 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. 8 Now I'm trying to dial down my PPT/EDC/TDC correctly, Aorus Master definitely has a good enough VRM that it will never be the limiting factor, unless you are doing something really extreme (e. Any lesser than that, and Performance litterary halfes, so a Single CCD Design Would be better. I used cinebench R23 as a benchmark and set PPT to a high limit where it never saw more than 89% usage. You can mitigate some of this, and potentially even increase boost clock speeds in lower threaded tasks, by playing around with EDC limits in BIOS, as well as Curve Optimiser. 180A EDC is set and the CPU does exactly that while hitting something like 70C. Setting mine to 200 allowed me to set an all-core -30, whereas at 160 I couldn't even get by at -20 on my best cores, -15 and -10 on the rest. you want to limit your value of the edc aka temps then your boost will go up. 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. 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 Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. I use PPT 200W, TDC 140A, EDC 160A. 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. 200 MHz). Testing needs to include standard stuff like Cinebench and you need to check each core individually using CoreCycler. Power limits are just limits. I'm running B550-MSI-Tomahawk - 64gb ADATA XPG ram - 6750xt, with a EVGA 650gt. 1 but mind you, you will get the issue that plagues 5000. Valheim; Genshin Impact; 5900x, asus x570 plus wif, 3200Mhz tforce ram and noctua nh d15 aircooler, stock temps been alittle high 50-55 and when gaming 75-80. Have you tried finding the right PPT EDC and TDC limits when I set it to motherboard it performed worse all I did was enable pbo and did a manual limit TDC 130 Turning EDC down from 154 to 125 helped immensely for example, which keeping it around 30-35 away from TDC. -30 on every core except 10/11 (at -20) due to prime95 and WHEA And all for no difference in light workloads and ~5% increase in aĺlcore loads vs auto limits. set my limits to PPT 195 EDC 140 TDC 130 no curve optimizer no undervolting llc left on auto set my thermal limit to 90c paired it with G Skill Trident Z Neo cl14 3600mhz 4x8gb slightly overclocked and for cooling the Ryzen 9 5900x an I should have mentioned that the prior OC was using Curve Optimiser. At some point, you will find they might go up then go down again. 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. Seems silly to me. Posting just in case there are other people like me who update to 1. EDC 120 in Ryzen master hit 4625Mhz when limit was default 90c. A report the fix. I was gifted a Ryzen 9 5900x a few months ago (I had a Ryzen 5 3600x). EDC limits will be ignored and you'll get the highest boost (EDC bug) 5900x, and 5950x, but I assume that increasing EDC will allow your effective clocks to boost Get the Reddit app Scan this QR code to download the app now. and i think i will be forced to lower the power a bit to get good temps (for my mindset) View community ranking In the Top 1% of largest communities on Reddit. So adjusting the TDC down probably won't help if it isn't peaking there. Gaming. Tips for lower temps 5900x? Lower PPT, TDC, EDC? And / or undervolt? Welcome to /r/Electricians Reddit's International Electrical Worker Community aka The Great Reddit Council of Electricians Talk shop, show off My settings in AMD overclocking submenu with a 5900x: 100mhz pbo limit, 200 wattage, 200 tdc and 180 edc. Here's a little on why. After you find your PBO limits, I'd think about whether you want to prioritize single core or all core For PBO would you suggest +50/100? the default limits are the same but I'd recommend higher values with a 5950x. For the 5950X this value is very important because given the chance Loaded "PBO Limits: Disabled" which uses the default CPU parameters for PPT, TDC, EDC. Terms & Policies I was hoping to find a way to raise the EDC 90A limit but I checked BIOS and if I manually change it under the PBO settings it just changes the big number so the 255, but the 90 stays the same, this means I never really get any cores over 3. +300mhz through bios and manually upped the limit to 90 degrees. Help needed for undervolting 5900x - PBO Limits. -- For my 5900x these values turned out to be PPT 190, EDC 175, TDC 125 -- For the 5800x, they were at 140, 140, 90 This resulted in a 6 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. what are your pbo limits ppt tdc edc Welcome to the Unofficial iRacing Reddit Community. EDC Limit [A] [160] No changes in scores in CB20 but not so much changes in temps too. 5900x low single core and multicore speeds after overclocking (PBO) So I added pbo a while back and I notice that my single core is only running at 4. TDC is rising between 33% to 100% for 1 to 8 threads, then stays at 100%. If your cooling has some headroom, just let your motherboard handle PBO limits according to its PPT/TDC/EDC limits and play with your max CPU boost clock override (e. So for me it was about finding a balance with the EDC limit. . Try setting it at 190-200. 5V near constantly even with no load. Trident Z 16x2 3200 14, Meshify 2, Seasonic Prime TX 1000, WD SN850 Cooler: Le Grand Macho RT All CinebenchR23 Multicore (PBO disabled 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. No CPU EDC limit shown. I just went for 200 limits on everything since this 65w chip Get app Get the Reddit app Log In Log in to Reddit. This motherboard is not enough for the 5900x. Too high power limits also cause a drop in single-threaded performance. Idk why, but this is For example my 5900X needs at least 88W (65W TDP). 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. Log In / Sign Up; Zen 3 (5900x) and EDC vs TDC Discussion OK, still working on PBO2 settings for a 5900x on a MSI Tomahawk 570x. CCX0 easily boosts to 4. x86. View community ranking In the Top 1% of largest communities on Reddit. I had to limit my EDC to 140 to make my 5800x and 5900x to run its full potential. My 5900X can handle these PPT 185 TDC 125 EDC 170 Screen after completion. PPT= 300 TDC = 240 EDC = 240 CPU boost override = 200 Yeah that's the other thing so with Vcoresome folks get chocked up about vcore is the just limit of the current (amp) that you Dear All, I have a system where the Thermal conditions allow a 65W (max) CPU to be used.

Reddit iOS Reddit Android Reddit Premium About Reddit Advertise Blog Careers Press. I have been playing around with PBO and motherboard settings for days, trying to crack the cinebench r23 For almost every other board need to increase EDC limit to 200~240,etc in order to gain pbo2(CO) performance. But there ist TDC and PPT Limit. This is bizarre. I can tell you is the 5900 runs hot, very hot, you are very much limited by the junction temperature because of heat density on the 5900x. I've lately been adjusting power limits to see how they affect my score in R23. The 5900x should perform best at some lower value than this but as you saw in my post it depends on the workload. Members Online. 3 GHz on all cores. After doing a per core CO, enabling PBO and setting limits to motherboard limits, it scores ~22000 in cinebench and ~12000 in Time spy. 5950X, when configured correctly, will be (and already is) more power Here is the thing. 4ghz with ppt 200/edc170/tdc 130 during extended r23 all core testing. Specs: X570 Unify. Or check it out in the app stores I'm using PBO2 to increase the performance of my 5900x. Checking HWInfo max Get the Reddit app Scan this QR code to download the app now. You set EDC and TDC backwards, actually lowering EDC below the stock value. Proper values for a 5900x are in the ballpark of PPT 250W, TDC 130A and EDC 170A, with Scalar X1. I felt like overclocking on my old Intel stuff was pretty straightforward. 23 votes, 78 comments. 5900X + X570 Aorus master + g skill trident Z neo 3600 impossible to use xmp For pbo don't use boost override or llc. 775 all core to get 24000 in CB R23. 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). so i switched back to 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. Tried all different PPT, EDC TDC configurations and it physically won’t go any further than 142w had this issue for awhile not sure what’s happening really because I’ve gotten it to EDIT: OK, so after realizing I drastically limited PPT TDC and EDC with air cooling, I started bumping those limites back up. EDC is ALWAYS higher than TDC, by definition. EDC 140A, PPT 142W. 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. So somehow I got a 5900X, and being the enthusiast I am I'm trying to see what kinda of clocks I can get out of this thing. No crashes. Open comment sort options and you can also manually define PBO Limits yourself instead of using the predefined "Motherboard" setting limits; you can define manual PPT/TDC/EDC values. Log In / Sign Up; Advertise on Reddit; Shop Collectible Avatars; solution is to use the "Thermal limit" in BIOS. And temperature is the only limit left in that case. EDC at 140 is definitely bottlenecking a 5900x because my 5800x needs EDC at 160 to get max performance. Learning PBO/OCing on AMD - 5900X Overclocking Hello all. This was with a custom watercooling loop using a crappy Alphacool CPU block. 6gz at all core on an h100iv2, I am running ppt at 200, Tdc at 160, and edc at 135, on curve all -18 and -10 on 4 best cores. My Ryzen9 5900X PPT 195 EDC 150 TDC 130 CL14 3600MHZ 4X8GB Overclocked cl14 3733mhz stable at 1. Yeah and now power limit the 5800x to the same values as 5700x and measure efficiency again. This information can be read on page 353 of the " Processor Programming Reference " PPR for short. I am coming from Intel - a 4790k to be specific. Encoding x265 using 'near-stock' (enabling one Asus option) keeps all cores at 4. 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. Anything below or above that led to worse results. In Bios, I manually changed PPT to 130W, TDC If I enable PBO and set max. But I never noticed anything.

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 throttles around 70c I believe this means we arent clock stretching. 8GHz - which is the rated max boost for the 5900X. 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. Reply reply csetjack15 • Yea, the EDC ceiling limit was introduced related to the 5800x3d, but setting EDC to single digits for performance was back around Ryzen 3000 (or sooner, but that's when I started my journey). 1 with too high PPT limit 280 TDC Limit 280 EDC Limit 230 Curve Optimizer: Cores 1-6 Negative 15, Cores 7-12 Negative 30 Temps hold around 60° when gaming and roughly 80° on a cinebench run with a 360 AIO. As a result the workloads which rely on EDC are throttling badly, while workloads with steady current (cinebench) are not. 200a TDC @ 1. If your on new agesa/bios updates keep your edc at 130 or it will bug out and lower performance. My 5900x does around 4. Sure, CPU won't damage itself, but for 5600x those limits are to much. After limiting EDC to below 90A, it would scale better and actually hit PPT. Turning down the limit a bit prevents it from flying straight to thermal throttling (90°C) Curve optimizer is part of PBO2 This should be a good starting point as the values to pick for PPT, TDC and EDC. New comments cannot be posted and votes cannot be cast. 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. Relevant parts: Ryzen 5900x stock Corsair iCUE H115i RGB PRO XT 280mm AIO cooler MSI Gaming X Trio RTX 3080 Radiator as intake Without having experience tuning PBO with a 5900x I cant give you accurate advice, but you can read up on either reddit subs or Youtube for PBO guides & a rough starting point to compare with whatever your motherboard is doing atm. 35-4. Yet the results and clocks seem to have it running better than when "uncapped" and Some motherboards do crank those values really high when set to motherboard limits in the bios. Share you might get it up to ~125W (considering what the 5900X stock settings do when ustilising 6 cores) and that is what Pay attention to hwinfo effective core clocks. 5900x though a dedicated 360mm AIO, ROG Strix x570 e gaming, 750w Corsair PSU, 64gb CL18 3600mhz. Any idea why this might be the case Launch amd zen master, write down the tdc, ppt, edc limits. 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 Still doesn't answer why EDC 120 on Ryzen master / PBO limit = motherboard gives entirely different results than defining in BIOS. 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.

My temps are in the 70s under all core workload without PBO, high 80s to low 90s with PBO limit set to motherboard(MSI X570 TOMAHAWK), and 60s while gaming. I've deleted my Reddit history mainly because I strongly dislike the recent changes on the platform, which have Get the Reddit app Scan this QR code to download the app now. EDC does have an effect on performance and you can't lower it until it reaches 99-98% because performance is affected even when its only 70% at the limit. Edit 2: Also, since the CPU regulates itself with PBO2, it does so in a safe manner. AMD folks seem to know what they are doing with EDC. Best bet on this is to set TDC and PPT manually while leaving EDC at 140 max. 4 Amps on the +12V rail. The selcted PPT / TDC / EDC limits in BIOS. 45GHz stable in Cinebench r23, and even higher (4.

Sure, start with: PPT 165, TDC 115, EDC 150 - negative curve of 25 but your curve will be unique to your CPU. Get an AIO heck with a CoolerMaster 212 Black Edition with just enabling PBO and TDC,EDC and PPT in cinebench r23 Also you can set temp limit in mobo setting under pbo settings. 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. I found 300/200/200 to be pretty solid for this MSI board. When running Cinebench r23 the CPU boosts to 4. The recent system has an i9-9900 in it. CPU will be watercooled and using Noctua thermal paste I also found decent luck tweaking the power limits, although noticed there's very sharp diminishing returns above 150 EDC. And hwinfo doesn’t lists it. I have a 5900X with a Thermalright FS140 which is similar in performance as Noctua D15. Ryzen 5900x temperatures so i got a 5900x on a b550 aorus pro with a be quiet dark rock pro 4 and on stock settings the cpu reached 92 degrees while gaming + streaming. 525 GHz during an x265 encode, and at ~80°C - that's seriously impressive compared to using Curve Optimiser which saw an all-core sustained boost of ~4. It's an odd one. 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. Reddit . PPT (I'm 90% sure) controls overall wattage sent to the chip. If you Dude we have the same cooler, try mine. Curve Optimizer: -15 offset all cores. if EDC is low, your highest boost Previously I had a 5900X that got retired into a rack server - but it wasn't a good clocker. Btw I was running a MSI board as well a X470. on my Aorus Elite Wifi the motherboard defaults for PBO are 360 TDC and 215 EDC. Your edc is really the limit to follow - the max is somewhere around the motherboard limits that can be set in the PBO menu. Your scores will definitely go up, as will your temps ;-) I am running at 4. 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 Get the Reddit app Scan this QR code to download the app now. 9 Recently I have been playing around with my 5900X and I was wondering if my numbers are normal. 2. Can I do a slight under clock to get the temps in order without reducing It just sits at 90c flat, TDC limit is always 95A. 9% I have the Ryzen 9 5900x all I did was enable PBO and found my limits PPT 195 EDC 140 TDC 130 no undervolting no curve optimizer LLC By unlocking PBO limits you are violating AMD’s stock configuration and therefore invalidating your Warranty 200W is enough for 5600, 5800 and maybe 5900X SKUs. SFX 700W PSU capable of supplying 58. Wanting PBO to boost higher by I recently started looking into PBO2 and Curve Optimizer for the 5900X I got recently. Go to ryzen master profile and 'Copy Current', then lower EDC by 5A steps and apply live while watching 'effective clocks'. Get app Get the Reddit app Log In Log in to Reddit. Essentially leaving CPB and PBO enabled, but limiting the TDC, EDC and PPT to set values. Then push clocks high to 4. Your curve optimizer values your gonna have to find yourself as each chip is super unique for optimized values. I want to replace it with an Ryzen 65 W counterpart but the Hi-Perf ones are OEM only (except the Ryzen 7 3700X). 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. All I did with my Ryzen 9 5900x in the bios was 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. 1000 undervolt control that you mentioned is obsolete and will inefficiently slow down the CPU. 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] Precision Boost 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). 185 PPT, 125 TDC, 170 EDC is generally accepted to be the best/most reliable combination PBO maxing at 60 degrees. EDC will reach the limit with the 5900X 204W and the 5800X consumes 208W. 45W (AM4 infrastructure H) PPT = 60W, TDC = 45A, EDC = 65A Mode 2 i. View community ranking In the Top 5% of largest communities on Reddit. Cinebench R20 with EDC 190A is only 8500 poins. Basically like Intel extreme tuning I've used on my Thinkpads to undervolt. (gaming only is around 70 degrees) TDC and EDC limits are much lower in the standard settings. Latest bios, cooler is a NH-D15. As daily, production and gaming settings I use 150A TDC and 190A EDC, and go higher only on like 4 benches (out of 40 or smth). 8% and 100% while PPT sits at 100% all the time. In my case, TDC and EDC trade off between 99. Your edc and tdc will determine the resulting ppt so start tuning edc for boost and then tdc for temps. If the EDC / TDC is at 100%, then it will underclock a bit so it doesn't degrade faster. 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. 7ghz during cinebench and no higher and it’s the same in game. My Crosshair VIII sets them to 395, 255, 200 for my 5900x. Passes Corecycler with 10 mins stress test on each core and no WHEA errors during low load and gaming scenarios. So I lock PPT and TDC at the stock 76W and 60A, give EDC a bit of headroom at 95A, because I saw that the cpu can bump up against the stock EDC of 90A in some workloads. 65W (AM4 infrastructure B) PPT = 87W, TDC = 60A, EDC = 90A In my tests on a 5900X the default EDC of 140 A (maybe +-5) results in the best performance. Some people say its dumb to lower these below stock Any other ways? Or has anyone an opinion to this and can help me? I will get the 5900x and NH-D15 chromax. Hopefully Asrock will provide the new AGESA versions for my specific x570 motherboard but thats for another day. Is there a way to limit the TDP of Ryzen 9 5900X or Ryzen 9 3900X to 65W witout losing much of a performance penalty?. 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. you can limit the power draw by lowering the PPT/TDC/EDC limits in the PBO overclocking section. With this at 105 I lost about 25mhz, and at 110 to 120 lost between 25 to 50mhz so it is part of 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. VRM-B2 Temps were still right at throttling, stalling at 89C thankfully. Enabling PBO can raise those values to the maximum supported by the motherboard BIOS. PPT, TDP, and EDC all represent different power limits. 90 GHz on single core CBR 23. Note that chip quality has a quite large range in newer CPUs - I see a significent difference in power consumtion and temps between my 2 CCDs in the 3900X here 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. Experimenting with 240/200/200, or even 240/140/140 seems to yeild little to no difference. i/e 5950x will pull more power so needs higher PPT (in my case 280), but TDC and EDC at 230A are way too much even for a 5950x. The default limits for 105W CPUs: 142W PPT, 90A TDC, 140A EDC. The limits I found worked the best on my setup when I had a 5900X were 222 PPT, 177 TDC, 188 EDC on an X570 Master (I forget the BIOS revision) with a custom loop, and I was optimizing it around the Y-Cruncher 2. These chips run on the rich side, in terms of Voltage (and Amperage), by default, probably to help them guarantee stability at advertised clocks across a wide range of silicon quality. PBO limits: PPT: 150 TDC: 105 EDC: 150 Scalar: auto Boost override: disabled Curve optimizer: per core Most of the cores are at -30, some are at -27 or -24, best cores are at lower offset (-9, -12, -15) Reddit . It's summer weather now though, so I am currently using the 45W Eco mode which keeps it around or below 60C in any Hello, I've been trying to undervolt my 5900x for the past couple of weeks, however I an unable to reach desired stability. 95GHz and regularly sustaining over 4. When running multicore tests my EDC is at 100%. I can't find the post anymore, but they reported that two different 5800x chips on one motherboard reached i just got a Ryzen 5900x and was looking better ways to undervolt. With stock PBO limits, mine rarely goes higher than ~75C, although, it's possible a BIOS update I did recently made it run slightly warmer. I have AMD Ryzen 9 5900X with Be Quiet Dark Rock Pro 4 cooler.

The "High Temperature Integer Threshold" is reset at 70c for AMD processor family 19h, the same as family 17h. I got the best performance with 130/170 on TDC/EDC for Cinebench. I know there’s many posts about this but most seem to have been wound up and don’t answer my questions so starting a new one get fresh responses. 46000 volts. Just scored 23,567mc -10 all core CO on the Ryzen 9 5900x never went past 69c during the 30-minute throttle test in Cinebench r23 no undervolting no extra mhz found my PBO2 limits scaler on auto posted it on Reddit Nervous King no undervolting scaler left on auto no extra mhz. Sure, I’ll explain it. I didn't really notice a difference between this and auto. Increasing EDC allows for you to set a more aggressive CO. I used to just whack PBO on "enabled" in the bios, which resulted in PPT 500, TDC 210, EDC 280. for Max CPU Boost Clock Override it's better to leave it at 0 and do the best curve possible for most games and multithreaded workloads but a +200 should give you the For stock clocks, even down to the 65W TDP numbers (88 PPT, 60 TDC, 90 EDC), my Cinebench R23 single-core hardly moved and my boost clock was still hitting up to 4. 4V which can hurt multicore OC. using sub-ambient cooling for overclocking) I would set the numbers much higher - e. When i switch to motherboard limits PPT AND TDC shoot way up (PPT 500/TDC 210) but EDC stays at 130. Run by Fans of the Worlds Leading Motorsport Simulation Game. You need to make small changes to your Curve Optimizer settings, and the power limits like PPT and EDC, and then you need to test extensively after each change. 55 and 1. 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. The 5900X was the pinnacle, Hi, I never overclocked before, but it appears now I am an underclocker due to this shitty 5900x chip I have. values, my 5900X will happily draw ~200W+ at ~85°C (I've only managed to get it to go over 90°C once at stock, and despite what people say, that didn't force thermal throttling at all). I set the scale factor to manual and set it to 10x. Or check it out in the app stores TOPICS. 5B benchmark. Manual oc disable pbo automatically. I then reverted my PPT/TDC/EDC limits back to motherboard, ran tests, and boom, Tmax = 90 again, multicore score 6038 I have a 5900x, and I can actually dip as low as -29 before the system starts crashing. "ECO mode" is a preset of this you could try out. PPT - higher is going to give you better performance always, with diminishing returns (as this is your power limit) EDC/TDC - have more of a sweet spot as opposed to “higher is always better”, because if you just set these to 200 each then your CPU will just use the highest voltage allowed by FIT to boost (thus chewing up more PPT), when it Recently I became the owner of Ryzen 9 5900x. fr/2db8wv You can effectively do the Seems like now it stays at 86A EDC / 135W PPT and slightly lower clockspeed. I expect to see some boost higher. Gaming 5900x should be tuned with PBO CO and power limits for more performance and efficiency, that -0. And that you can set default limits found in Ryzen Master. 95 GHz and sustains 4. Cooling it is an Arctic Liquid Freezer II 360 rev 4 with the offset brackets and Arctic MX-6 The odd thing for me is that with PBO and any Asus 'enhancements' disabled in the BIOS and everything on stock, my 5900X boosts to 4. 5900x I’ve seen like to be around the 170 edc level for max scores but some might want more or less peak current I went on reddit and OC forums and did some more reading, and I found a user who tested two 5800x chips on two motherboards. Set them limits high (perhaps to "Motherboard"), run a multi-threaded workload starting with a low thread count (2×) and working your way up while monitoring your clocks to see when your CPU will hit its throttling temp Note the highest TDC and set this value as the TDC limit in the BIOS As intended, the 5900x has those super fast jolts where it shoots up to 70, down to 35, up to 76, down again but this paste is the real deal. I'm running 300/60/100 with per core offset + vcore offset and got 11900 cb23. reReddit: Top posts of February 28, 2022. Reported power limits are as expected (AMD defined PPT, TDC, EDC). First I tweaked PPT, TDC, and EDC with PBO enabled. Thanks PPT – 200W, TDC – 135A, EDC – 180A-17 on the curve optimiser on all cores except the preferred cores (as listed by Ryzen Master) where the first preferred on CC0 is at -11, second at -15, and on CCX1 first is -14 second is -16 Specs: AMD 5900x NZXT Z73 cooler with 6 (push-pull) Noctua fans - overkill I know, but cooooool Reddit iOS Reddit Android Reddit Premium About Reddit Advertise Blog Careers Press. idle boost spikes. Lower PPT, TDC, EDC works apparently great for some people but only for cinebench score. Then I tweaked TDC until it showed about 96% usage under load during cinebench and then tweaked EDC. Best bet on this is to set Your edc and tdc will determine the resulting ppt so start tuning edc for boost and then tdc for temps. I went on reddit and OC forums and did some more reading, and I found a user who tested two 5800x chips on two motherboards. g. Where do I find these default limits in ryzen master for my 5900x? I haven't actually tested the EDC bug on my 5900x but it was just crossing my mind this weekend. Furthermore you don't really have to work with your current limits. Here are some CB23 comparison numbers: on my 5800X - when I increas EDC Limit to 300 i get much better AIDA L3 Cache Results. 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 Reddit's largest humor depository Members Online. 3v in a single core workload, then it can do it without burning itself, since it doesn't go over the EDC limits. I had put my power limit at 600 watts with the EDC limits to 500. Try 250/170/130 - PPT/EDC/TDC. These correspond to "motherboard limits" This has been how the system has been running happily for about a month I have already found and stress-tested my curve optimizer values for my 5900x while using 200/140/140 for PPT/EDC/TDC on my X570S Aorus Master latest Bios AEGSA 1.

Two questions: 1. This is my configuration: Ryzen 9 5900x rev. OP might be on an ASUS board which allows you to run things like FMax Enhancer and Scalar while maintaining stock the PB limits. Or check it out in the app stores EDC and PPT on a 5900X increases performance? As a byproduct the EDC limit "disappeared" from HWiNFO entirely and the CPU is somewhat capped to 165W. starting with PPT 300, EDC 150, TDC 150 seems like a good starting point. I'm currently using stock values: PPT: 142W, EDC:90A, TDC:140A. mistermanko • • Edited . That's definitely reasonable. Cooler is a Noctua NH-D15. 9-5. 3 with temps at 82. but the settings i had were 195, 135, 135. According to MSI this board's max is TDC 200A and EDC 240A with a decent sized heatsink on the VRMs. Running with a limit of 65C will seriously limit performance, what's the point of getting a 5900x then? 85C limit is a lot more reasonable and you'll lose only less than 5% performance, but anyway if you're not reaching 90C continuously there's nothing to worry about. 7 without realising they'll effectively be stuck with the default EDC limit for their 65W TDP processor. In the cpu voltage option I choose offset - 0. Everything works fine with pbo etc. The AMD default for the 5900X seems to be : PPT 142W, TDC 95A, EDC 140Amps. 125. Really extending the EDC and PPT limits don't do a great deal because of temps. e. This was done supposedly to prevent the 5800x3d from frying it self regardless it still prevents high boost on regular 5000 So I changed my settings to -30 all core and messed around with the boost offset and PPT/TDC/EDC limits I really can't recommend using it from my experience with a 5900x and a friends 5600x. When I remove power limit and increase edc and tdc cpu Are there similar easy settings for the 5900x? My 5900x will come next week and I plan on doing a similar OC if possible. 475V without overheating (thanks to water cooling). iirc I have 155/135/120 PPT,EDC,TDC using a Cryorig air cooler.
