Undervolting my 5800X
Undervolting my 5800X
I'm just getting started with CO. If I begin, I think using values similar to yours for PBO would be a good idea, then switch to all cores with the Curve optimizer and try -25 as an example. Alternatively, I could pick 2 cores at -15 or -20 and leave the rest at -30 or -25. Also, if Ryzen Master's optimization Auto takes about an hour, should I use it for all cores or set individual core values?
I had the best results with the setup I currently use, so I’d recommend something similar. I entered everything into the BIOS instead of Ryzen Master, just used RM to identify the cores. I’d test my settings and adjust as needed. It might be wise to keep HWinfo64 running while you’re using the PC—it will monitor any WHEA errors if the undervolt is too high for your CPU.
Okay so I came back with multiple tests and fiddling with PBO and CO
Here's what I tried so far:
I did as you suggested: set the PPT & EDC Set to 120, TDC Set to 80 ~ Ran cinebench or OCCT and still temperatures spike to 90 instantly.
Used CO to set the preferred core to -15 and the 2nd best to -20 and left the rest at -30 - Running cinebench or OCCT still get the same result
I tried setting my favorite core to -25, 2nd favorite to -20 and the rest on -30 and I still have the same issue.
The only time where I didnt have temperature issues is where the TPU is set to 1, from what I have noticed it changes the Core ratio to some specific value and adds a positive voltage offset to Core? not sure what is exactly happening but it was not stable. After running OCCT with TPU 1 I got random reboot so it was not stable.
I'm still annoyed by this, is there any solution I can take that could help? Other than drastically eliminating most or a large chunk of my performance? if there isn't, then I think I would keept it as it is until it dies or something
TPU should be disabled (for now). It's an built in overclock from Asus,
