undervolting 5800x3d

[Koziolek]

My Ryzen 5800x3d runs very close to 90 deg so I am trying to undervolt it with PBO 2 tuner. It works pretty good, with -20 offset it gets 5-6 deg cooler in Cinebench

 

the problem is I have to put the values manually every time. I tried to add the offsets to target line in the shortcut at the end but it has no effect

 

"C:\Program Files (x86)\PBO2 Tuner for 5800X3D\PBO2 tuner.exe" -20 -20 -20 -20 -20 -20 -20 -20

 

the patch is correct because it opens the PBO but without offsets 

 

Anyone has any idea what I am doing wrong?

Hi I don't know which motherboard you are using but a more recent bios release has unlocked most pbo features as per stock Ryzen processors so you can undervolt from the bios which is probably a bit easier.

 

90 deg seems a bit hot what temps are you getting in Il2 gameplay mine rarely goes above 50 deg but It might hit 70 plus degrees in some benchmarking apps.

This is the same board as i have , if you have recently upgraded your bios you can undervolt from there. I have mine at all core -30 with no issues.  I think PBO was unlocked in bios version 4408.

thanks for the help

I did it from BIOS as you suggested. Nice 88 deg in Cinebench, lower in games

 

I still don't know why the shortcut did not work, but it is just my curiosity only now ?
