Reply reply Ryzen 7 7800X3D undervolting attempt upvotes At least CO and PBO still seem to be options and Async clk should do a lot better than the 5800x3d could. Undervolting at -50, -40, -30 have all had my CPU thermal throttled at 90. It consumes 80-90 W max by default, so lower power limits, or PBO won't help. Should I change the throttle thermal limit as well or just leave that default? Also can I leave EXPO disabled with PBO curve optimizer enabled? I have paired the 7800X3D with an Gigabyte X670 AORUS Elite AX and 2x16GB G. Confused if I should take an air cooler or aio liquid cooler with it. 1ghz. 1v to 1. By manually using the curve optimizer (and power and thermal limit) we can fine tune those values to our particular silicon to My 7800X3D (running pbo and -5 offset on the 2 fast cores, -10 on the rest of them) regularly records a max on half or more of my cores of 5. 83v, lowered vddio from 1. 7800x3D PBO, CO, cinebench , questions Help (CPU) Using the Gskill neo 6000mhz cl30, asus tuf x670E gaming board with my 7800x3d newest chipset from amd website, and new bios from mobo. ~10ws less idle, but I find it strange that it is still that close to operating consumption. - svenlange2/Ryzen-5800x3d-linux-undervolting This is with pbo on and no undervolting yet Reply reply Ok-Gur7779 • im glad to see 7950x3d owners not complaining about dead chips. If the CPU is completely stable at stock, then you probably just got The SOC voltage default setting is AUTO for ASUS boards and it is notorious for auto incrementing the voltage to unstable levels when turning on PBO to OC or undervolt. www. 7800x3d would randomly run aida64 sha3 butter smooth or just black screen crash at stock settings no pbo.

Ryzen Hey, I just wanted to share a quick overview over the results I got, with like no effort at all. My 3rd core can't handle any undervolt and it fails to start in Prime95 at -30. With EXPO and PBO enabled, my Cinebench R23 MP score is usually in the low 18ks, (best around 18350) and my temps during CB top out around 82-83C, with cores going at 4. For me, the I want to undervolt my cpu curve by -20 to -30. My setup: Ryzen 7 7800X3D AsRock Manually tuning PBO as OP did will of course give the best results, especially for SFF builds with low profile coolers like that IS-55. I do this by leveraging asynchronous eCLK to stretch the V/F curve beyond Undervolted, PBO 90 level 3. Undervolting usually provides better efficiency at a loss of negligible performance. I too started with -30 but that was extremely unstable and I got frequent reboots. passes all that. A Windows utility simplifying overclocking, undervolting, and enabling PBO on Ryzen CPUs, Ryzen Master allows the average user to get more out of their AMD CPU without heading into the BIOS. Can confirm this guide works really well , still testing though. RAM on the QVL. temperature (c): 88. 0 Ultimate 360mm - Fractal Planning to get a 7800X3D soon.

My AC is targeted to 18ºC but I doubt the room temperature is even near that. So testing PBO curve optimiser is easy for high load testing eg occt sine core small fft etc But it seems the random crashes you get while gaming are from very light loads. not sure what else to do to figure out which core is giving This helps a lot. 100. Thoughts or recomendations? 7800x3d undervolting and SoC voltage help needed Hi, I recently built a 7800x3d system with a msi pro b650p MB. co/5vHd4y4 The offset undervolting is the board calling the shots, it can increase performance but not like curve optimizer. Curve Optimizer is a more elegant undervolt but changes the the "curve", this results in better performance as long as there is Undervolting using PBO will allow your CPU to boost near to max clock speeds using less voltage (heat). if undervolting severly lowers the watt use of a conponent without affecting performance too much, it is worth it. Having those really good charts shows just how much extra headroom One thing I noticed, which most reviews failed to report, is how ridiculously effiicient you can even boost this chip further. Stress testing will only reveal if your undervolt is fantastically too low. One weird thing is I have PBO in 2 parts of the BIOS - one under Setting->Adv CPU config and After PBO tune and 30 undervolt, I ran my 7800x3d on cinebench multicore for 30 minutes and the max temperature was 76 degrees. Undervolting it will typically give you better performance that intentionally overclocking it, since it will lower it's power use and thus Undervolting only reduces power draw by about 10-15% under the very best conditions, and is a ton of work. github. 8v to 1. If you're at the 15C for 100Mhz point then you either pushed WAY past diminishing returns point and should turn back. What should I change my PPT, TDC, and EDC to in my bios settings?

Best Efficience. Using the tool Project Hydra I've attempted an OC of my RAM using Buildzoids timings (so it's Hynix die despite being CL38) which has been fine, and a PBO CO undervolt on the 7800X3D. Skill Flare X5 Series 32GB (2 x 16GB) DDR5-6000, so I assume I am good to turn on EXPO. Set the voltage at 1. My suggestions for a "quick and dirty" 7800X3D undervolt (one that is reasonably stable for most people that doesn't take several days of effort) are to do the following: Boot into BIOS and set your CPU SOC to 1. Im a newbie at this and learning as I’m going. you can test with cinebench until you find the best set for you. 15v, and vddp to auto. My cinebench r23 score is around 18600 and compared to -15 or -20 all cores on the CO I noticed that the CPU indeed clocks higher when using -30 all cores (~4860 How to optimize the 7800x3D.

PBO + Curve Optimizer -20 all core undervolt. Just thought I would share if anyone has one of these chips and wanted a boost in performance. was a stability test - I was just benchmarking. Cooler: Dark Rock Pro 4 - fan curve set to Standard . My stability test was playing the game because of which I did the undervolt in the So ive just build my pc with the Ryzen 7 7800x3D, which is a big upgrade from my last cpu granted, however with it came really high temps / temp spikes when playing games as well. Thankfully with the 7800x3d, AMD allowed support for one of the best PBO features Curve Optimizer, which allows you to adjust the voltage/frequency algorithm and effectively undervolt your CPU for every given frequency while still retaining the benefits of PBO itself. You will need this to see your CPU Voltage and Temperature and to later confirm that your Settings work. hello there awesome community, im looking for some guidence & assistance in trying to figure out the proper way to optimize this brand new system i got, which took some time to assemble as well but it seems to be quite worth it!
