Playing with increasing the clock speed but it crashed at +200 on the multi core test. My final settings where PPT 70,TDC 50,EDC 75. In PBO and AutoOC modes I can set PPT, TDC, EDC but in Manual mode those values don't seem to exist (This is true in Ryzen master and the BIOS). I find eco mode enough for now, temps stay around 60'C and still plenty of performance. 15v instead of 1. 35v on a allcore workload 65A x 1. Any and all advice is much appreciated! (The included screenshot is from during the multithreading test) If your temps are low, as long as the tdc, edc, ppt values are not hit (look in hwinfo64) they don't have an effect (in theory). normally the voltages for ram should always stay 1. So 1x is actually the default and is not overclocking. May 6, 2024 · I have done lots of research and tinkering to cool the 7800X3D with little to no performance loss in gaming and everyday workloads. This is being done under the AI Tweaker bios tab rather than the Advanced tab, because any time I apply changes to PBO under the advanced tab, they don’t stick when booted. As I lowered each value the clock speeds went up and stayed there longer. I can change Curve Optimizer's value from "All cores" to "Single core" by pressing enter, but again, enter does nothing if I hover over "0 Anyone have additional tweaks or resources they can point me to to mess around? 7950x w/ PBO undervolt by 100mv, 32gb DDR5-6000 EXPO CL30, Kraken X72 (without AM5 brackets), Gigabyte Master X670. Then try a PPT of 140. Advanced > AMD CBS > NBIO Common Options > XFR Enhancement > Precision Boost Overdrive, set it to manual. EDC also has an effect on temps, but not nearly to the extent of TDC IMO. 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. Config TDP offers default PBO settings for Ryzen CPU such as 170W Ryzen 9 7950X/7900X and 105W Ryzen 7700X/7600X, and also 125W/95W/65W/45W profiles. But with the factory-defined clock speeds and power consumption limits (TDP, PPT, EDC and TDC), nothing of this is visible under full load on all cores: Ryzen 9 7950X and Ryzen 7 7700X not only consume more power for the same project in HandBrake than their respective predecessors. In HWInfo observe CPU PPT. As far as I know this doesn't affect the GPU power, but limits the CPU heat Set PPT to around 220-250. If I set my own PPT values (AMD CBS -> XFR Enhancement in Gigabyte B550I BIOS), for some reason I still see them reflected in Ryzen master even though PBO Limits are set to disabled. And honestly using curve optimizer is so easy, most 7000 owners should do it. Nothing crazy so you can leave them on Mainboard limits, I just like to be precise. Don't get why that is. Idle temps of 41C - 43C and gaming temp of 65C - 70C. 3 with temps at 82. Change those default values to the following: Posted by u/RazerPSN - 48 votes and 86 comments Jul 25, 2016 · All I want to do is lower the PPT limit on the 7700x, however when I set PBO limits to 'manual' the other TDC/EDC values are set to 0. 5GHz all core turbo and 4. The PPT limit won't allow TDC or EDC to cause socket power to exceed PPT's value. PPT is the total power that the CPU can intake. ini. It may just be mobo related (VRMs and one or two 8pin ATX12V connectors etc). PPT is the wattage limit. The default limits for 105W CPUs: 142W PPT, 90A TDC, 140A EDC. But changing the other PPT, EDC or TDC limits above the default is overclocking, like in your case. There are essentially 3 levels of Precision Boost Overdrive Aug 21, 2023 · Question: What dose everyone use for best performance and great undervolting? Is this a good and safe settings for Ryzen 5800x3D for longevity PPT @ 140W TDC @ 95A EDC @ 140A Thermal Limit: 80c And Curve Optimizer -20 to -30 per core Is that good for safety and longevity of the Ryzen 5800x3D 142,000 PPT 110,000 TDC 170,000 EDC Whilst running at an all core boost of 5. 7800X3D have 1 CCD, 7900X & 7950X have 2 CCDs. And that's what makes me wonder. 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. It's the toastiest of all Ryzen 5000s I think. Np, I recommend using something like PPT 142 / TDC 96 / EDC 125 with +150 frequency offset. That should put you in the 16k range for CB23 multi and ~1640 single core with boosts to 5ghz. I've tried setting PBO limits to Motherboard, Manual and Disabled but can't get it to pull more power or boost higher. Then figure out how much of a performance decrease (as well as temperature decrease) that you would be fine with. your ppt might be Set to 200watts but i think you might be limited by tdc here. 5 hours to optimize the curve optimizer. If any hit 100%, increase limit and recheck. TDP*1. So my question: Does the value 0 on PPT/TDC/EDC = Default? The potential lack of the ECO-mode does not prevent you from using it, since it is nothing but a preset of PPT/TDC/EDC settings. Apr 22, 2025 · Precision Boost Overdrive 2 builds on the PBO implementation of Zen 2. Your cpu will run at somewhat around 1. Undervolting (and optionally tweaking PPT EDC TDC settings I'm PBO) will not only radically reduce power consumption and temperatures, but will also significantly improve performance due to increased voltage and thermal headroom. And how they interact is interesting. Jan 7, 2025 · Just keep EDC and TDC at stock. Nice and stable, been running it for a week, playing games etc. I get 65-75°C with a Wraith cooler on my 5800X, ~4. When choosing power saver power plan, all of them are not a 99%, when using ryzen balanced or ultimate perfomance then they EDC go to 99% but PBT and TDC stays normal, when stress testing PBT AND TDC go 99% and EDC go down to normal. In the BIOS, I have set PBO to "Advanced", PBO Limits to "Manual", For the limits I have put in PPT = 120 TDC = 80 EDC = 115 Precision Boost Drive Scalar = "Manual" and "10X" Max CPU Boost Clock Overdrive = 0 MHz Curve Optimizer = this one takes some time. I've choose CPU TDP config to 105w ( it make PPT 142/TDC 110/ EDC 170) I've set Boost Clock Override to +200 Thermal Limit untouched From what I understand, PBO boost until one of those limits are reached. Eco mode is broken in latest Crosshair VIII bios. In my case best would leave EDC/TDC stock and just lower PPT to 110. Yet both can be so much more efficient. Stability test with Corecycler. My CPU is a Ryzen 5 3500 65 watt cpu. Can anyone point me to the correct settings? The power aspect and the curve optimizer aspect (exclusive to Zen 3/4). Should be similar on other boards. Best 2 cores set to negative 5 and the other 6 cores negative 15. TDC can be raised if temps are low and performance suffers (e. Tuning in the CO increases the efficiency of the affected cores and reduces PPT Limit: 88000 (AMD stock 105W recommended settings: 142,000) TDC Limit: 75000 (AMD stock 105W recommended settings: 110,000) EDC Limit: 150000 (AMD stock 105W recommended settings: 170,000) But no results. 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. By only lowering the 65A TDC Limit to 15A and the 95A EDC Limit to 35A with the 24W PPT Limit. I have mine set to 65W / 75A / 150A I think (not at home right now). Looked OK. Settings are persisted to BIOS. 5600x reaches 4 In HWInfo observe TDC Limit and EDC Limit. Lastly your tdc limit is so high your chip can hardly draw half of Hello. I forget what the EDC and TDC default values are, but they're probably reasonable around 100A or less when temp constrained. I've noticed that the PPT, TDC, and EDC values reported by Ryzen Master for my system are significantly lower than AMD's official default I would start with playing with ECO mode if there's a 105w option,, AMD had a recommendation for the PBO limit values for 105w = PPT: 142 TDC:110 EDC: 170 & a negative curve, see how it behaves/benches etc, then adjust to your balance of temps/performance. It runs hot to begin with because it has the same power values of the 5950x with half the cores. 45W (AM4 infrastructure H) PPT = 60W, TDC = 45A, EDC = 65A Welcome to /r/AMD — the subreddit for all things AMD; come talk about Ryzen, Radeon, Zen4, RDNA3, EPYC, Threadripper, rumors, reviews, news and more. 90c temps and high power draw (with pbo maxed out, or on a manual oc) are nothing new at all. 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. Note it. If you set them all at 200, the numbers are out of range. --apu-slow-limit=<u32> APU PPT Slow Power limit for A+A dGPU platform - PPT LIMIT APU (mW) 3. yegymwhd fhf oivv jxeoac wvcc tpd bke jymzlpr gmpk pbzqv
