5900x tdc so uh in december i've built my new pc and here are the main specs Gigabyte B550 AORUS MASTER AMD Ryzen 5900x G. Just copy the values you read out when PBO is disabled. PPT/TDC, set to AUTO, see amendment to section 7. I set Maximum Processor State to 99%. Just changing the AI Tweaker PBO value to Enabled, they go up to 395/160/190, OC Mode becomes PBO, and performance goes back up to what I was seeing (still 90C). sweet spot seems to be 175 edc for my 5900x setup. I'm still learning and I was a little confus Changing your EDC will lower temps but not nearly as drastically. Once you increase TDC you will get closer to the PPT TDC is what will determine your maximum clock speed. Cooling is Arctic II Freezer 240. PPT is 900W, TDC is 480A and EDC is 600A. Single core performance, as far as I can tell, is virtually indistinguishable from stock settings (both with curve optimizer enabled). The 5900X has a 142 watt PPT limit. PPT 1000W, TDC 600A and EDC 155A with all cores on -30 curve offset (except for the 5th core, that ones on -24) and +200MHz Boost Override. It's a Ryzen 5 3500,6 cores 6 threads. PPT/TDC: The maximum value your BIOS supports 5. 050-5. The Ryzen 9 5900X has a TDP of 105 watts and a PPT limit of 142 watts. While PPT = 240, TDC = 200, EDC = 200, I find that they aren't stable when tested. I'm running 200ppt/170tdc/130edc on my 5900x and I keep hitting tdc limit but cannot rise it further without hitting 90c with my NH-D15, so I left it there. Of course, this will also depend on individual CPU, meaning, there are some Malaysian batches that prefer higher values, some prefer lower, etc, but all are within 10A difference. This is stable in OCCT, Cinebench23, Geekbench and during daily use and gives me the highest scores in benchmarks. 5900X CTR 2. This TDP means that the Ryzen 9 5900X CPU will consume a maximum of 105 watts of power at its base frequency of 3. Later stepping's on the AM4 5900X can do 5. Haven't seen my TDC utilization higher than 137. For 5900x gigabyte aorus pro v2 crucial ballistix 3200 cl16 64gb micron rev b scythe fuma 2 win 11 So i've been fiddling a bit. After watching some YouTube videos, 1 caught my attention and I followed his lead and my temps came down by about 10-12c running Cb R23. then when i set the PBO limits to disable: The default PPT for the 5900x is 142, and I lowered it to 110. In Bios, I manually changed PPT to 130W, TDC 60A, and EDC to 70A so as to not overtax the P PPT, TDC, EDC set to manual (220w, 160a, 165a) (I am limited by temps. Update to the update, I have verified @maka0's optimal settings. SFX 700W PSU capable of supplying 58. 433A. 15GHz with good cooling typically. 1 - Ppt is fine not maxing out . And that's what makes me wonder. You want around 95-99% usage on tdc for the most part, if your cooling can handle it or until performance degrades in your use case. My 5900X did the same thing and is/was hard to cool with my Noctua NH-D15S (two fans), Check your TDC/EDC/PPT values to see if they are running stock, or if your motherboard is pushing higher limits. Runs hotter but get extra performance. In order to achieve an actual “overclock” on Ryzen 5000, we’ll need to dive into three major components – PBO2, Curve Optimizer and Power Settings. 1. I believe your EDC should be = or higher than your TDC. 05v. The default settings are PPT 142, TDC 95, EDC 140 - if your -30 offset is stable, you can probably do PPT 125, TDC 80, and EDC 120 and still get the same performance. 0GHz-5. These correspond to "motherboard limits" This has been how the system has been running happily for about a month or three. 0. - Found most efficient PPT, EDC, TDC values for max boost clocks, lowest deltas between clocks and effective clocks deltas, keeping max temp to 90C or less) for AVX/non-AVX loads. I have enabled PBO & use the automatic Curve Optimizer. EDC being higher can allow temporary peaks above your TDC. This setup gave me just under 23k in r23. I'm using Corsair platinum AIO h115i 1st setup I get 70°C on CB and 2nd, 80°C At stock, the 5900X should get around 20,500 points, so you can use that test with your lower PPT, TDC, and EDC to make sure you aren't getting worse performance than stock. 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. Single core performance, as far as I can tell, I put a Ryzen 9 5900x in a shoebox ITX case. Bios is AGESA 1. Too low TDC has negative effect (but lowers temps). Simply put, higher TDC usually means higher clocks. . TDC seems low but increasing it just by 10 or 20 increased temps 10c or higher for very small cinebench benefit. Too high TDC also has a negative effect if the cooling is not good enough to I'm using PBO2 to increase the performance of my 5900x. ) PBO clock boost: +50Mhz vCore offset: -0. Didn't see much improvement on temps, so then went into the Windows energy settings and opened the advanced options for Balanced. I have an AMD 5900X in an ASUS x570 Gaming TUF Pro motherboard (latest bios 3001), Default, with PPT/TDC/EDC of 142/95/140, and the system behaves similar to stock. ? And is it clever to turn on/off PBO? Lower PPT, TDC, EDC works apparently great for some people but only for cinebench score. My second option is 185, 125, 170. From everything I've read and my limited understandingEDC is the max amp for boost in spurts and TDC is max amp for sustained? How to find optimal TDC for my Ryzen 5900x, I'm a noob. Left EDC and TDC on stock values. CPU: AMD Ryzen™ 9 5900X TDC seems low but increasing it just by 10 or 20 increased temps 10c or higher for very small cinebench benefit. Try PPT 165, TDC 115, EDC 150. So watching youtubers using Corecycler I find my curve settings and they are stable with corecycler running for 5 days straight. PPT 178 EDC 132 TDC 117 Undervolting is apparently the best (maybe the only good?) way to lower the temps of the 5900x etc. EDC nearly always hits 100% under heavy load anyway, so with these settings you will be mostly TDC limited. 075ghz. I have a stable overclock 4725/4675 Mhz overclock and undervolt on my Ryzen 5900x. Right now with my monoblock I settled in 230 PPT , 100 TDC and 140 EDC. Skill Trident Z RGB 32gb 3600 Right now i dont wanna mess with it and learn how to manually OC my Ryzen so i've just put it to auto oc mode and there is only one question. 7 GHz. Electrical Design Current (EDC): 140A 5950x, 5900x and Best performance for 5900x hovers around PPT 250A, TDC 140A and EDC 170A. I've got the 5900x on Asus x570 gaming F. EDC In my tests on a 5900X the default EDC of 140 A (maybe +-5) results OK, still working on PBO2 settings for a 5900x on a MSI Tomahawk 570x. 5B benchmark. How best to overclock your Ryzen 5000 series processors such as 5900x, 5950x and 5600x beyond PBO so as to maximise performance whilst minimising power used Undervolting is apparently the best (maybe the only good?) way to lower the temps of the 5900x etc. Without limits it does (248watts - 167 TDC),(228watts @ 160) and (217watts @ 150). Start around -20 CO and run a program like CoreCycler to test stability. noticed the same with my 5900x and x570. Need some help with my 5900X + Tomahawk X570 combo. CPU VDD Telemetry Offset Value 6. 15v. That's my normal settings but I do also use per core custom curve. Test these with no XMP or TDC - thermal design current, lowering TDC has benefit of lowering temps and marginally increasing boost. Best bet on this is to set TDC and PPT manually while leaving EDC at 140 max. If the limits you found work the best, keep using them since they're the best for your setup. I think stock values are: TDC 95A, EDC 140A, PPT 142W. TDC: 80A EDC:110A And it gave me extra 800 points (almost 12k MT score) in CB23 over the following stock values. When I installed my 5900x and tested it before adjusting the Mobo limits of Ppt, Tdc, Edc and Curve Optimizer it ran way hotter. For my 5900X that is 142 PPT, 95 TDC, 140 EDC. Save Share 5800x - adjusting PPT/TDC/EDC Limits on PBO got me minimal drop in R20 multicore scores and major drop in temperatures (90C to 71C), GUIDE INSIDE I have a 5900x, and I can actually dip as low as -29 before the system starts Set up: Ryzen 9 5900x, Aorus x570 Ultra, Corsair Vengeance Pro 3600Mhz (3200Mhz bdie kit, OC'd to 3600Mhz w/ custom timings) - 850w Corsair PSU. I put a Ryzen 9 5900x in a shoebox ITX case. 5V. stable at -5 but temp was too high for my taste. 5900x not pulling over 142w . The AMD default for the 5900X seems to be : PPT 142W, TDC 95A, EDC 140Amps Two questions: 1. The best score I got was 6519 and that was having PPT 85, TDC 55, EDC 80. But since you're also running a sff system my suggestion is to let the limits at Hi Does anyone can tell me what are the default PPT/EDC/TDC for a ryzen 5900x and what would be good valued to keep a good boost without having high temps? Thanks !: With good cooling your PPT will probably max around 200-215W and TDC around 120A-ish. EDC will almost always hit 100% and TDC will be close to 100% under certain load. 0 D included. Click to expand 195 PPT, 135 TDC, 140 EDC getting 22700 in cinebench with jus a cooler master ml240l v2 . 4 Amps on the +12V rail. 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 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, The stock 5900X has only 142W power limit and 95A amperage limit which imo is way too conservative. 5900x, and 5950x, but I assume that increasing EDC will allow your effective clocks to boost further and be closer to the reported speeds. All core curve -20. I've tried numerous settings and testing them by using CB R23. When opening simple tasks with Hwinfo64 open I can see it boost to 5. Everything else on auto. Save Share A bit stuck getting my 5900x overclocked so figured I'd ask here as some of you have already figured this chip/platform out a bit. Hey guys just trying to dial in the best PPT,TDC,EDC values for 65 watt cpu. Thermal Design Current (TDC): 95A 5950x, 5900x and 5800x and 60A for 5600x. With GREAT cooling you can probably handle those values constant while staying under 90c. On my 5950x I have PPT uncapped, EDC 200, and use TDC to control temps set @ 150. PPT: 78W (All sources say ti should be 76W but HWInfo says it goes all the way to 78W TDC:60A EDC:90A The temps went up by around 15 degrees and voltage by around 0. Max temp of 89C. I set PBO limits to motherboard & got the following limits: PPT: 190W TDC:128A EDC:215A. TDP refers to the maximum heat a CPU generates under typical operating In my case, my 5900x is easily able to go past 5GHz. Tweak TDC by 5A steps to wrangle in the temps. This can allow you to bump core voltages up, but do not advise going beyond 1. The AMD default for the 5900X seems to be : PPT CPU: AMD Ryzen 9 5900X | Motherboard: MSI X570 Tomahawk Wifi | GPU: EVGA RTX3080 FTW3 Ultra | RAM: 2*16GB Crucial Ballistix DDR4-3600 @ 3733MT/s 15-17-16-32-1T | SSD: Crucial P5 1TB NVMe | Hard Drive: When selecting the best CPU cooler for the AMD Ryzen 9 5900X CPU, it is essential to consider the TDP and PPT limit of the processor. 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. PPT (Package Power Tracking) is an AMD CPU feature that monitors power consumption and reduces performance if the limit is 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. I'm pretty sure I've found my stable curve and boost now working through EDC/TDC and what they actually do have me confused. Latest bios, cooler is a NH-D15. 135 TTP, 100 EDC, and 90 TDC seem to give the best results. Note the highest TDC and set this value as the TDC limit in the BIOS From here I'd adjust PPT next, leaving EDC as high as possible due to its impacts on "single threaded, bursty" performance Reply reply Zen 3 frequenzy / temperature scaling - 5900X GamersNexus saw a peak power draw of 193 watts for the 5900X measuring draw off the EPS 12V rails, so I am assuming the discrepancy is the power draw of the motherboard, correct? TDC 165 EDC 135 Curves -10 on 1,4, -15 on Package Power Tracking (PPT): 142W 5950x, 5900x and 5800x and 88W for 5600x. 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 draw 210w before with better scores. I used to just whack PBO on "enabled" in the bios, which resulted in PPT 500, TDC 210, EDC 280. afalzb pbafms cmj pkrap oytxv vredhm xyvz xot byxf xwqxjtggq
