Tried in another sub-forum with no response, but maybe it's not CPU related, so let's try here as well, hope it's within the rules:

Been having crashes when the computer's under heavy sustained load, but all attempts to finding a specific component have failed, which leads me to thinking general PSU, but, I did find one thing that was weird.

In AIDA64, there's a +1.8V option, which seems to correspond to the CPU VDD18 on HWInfo.

Mine remains in the range of 1.254-1.287. It should be 1.8-2.0 or so.

Ryzen 3700x, Gigabyte Aorus Elite B450. Updated to revision F52 today (60 is still in beta for Gigabyte) and I can't seem to find anything in the BIOS to control this setting.

PSU is Antec HCG 80+ Bronze.

Is this a motherboard issue, PSU issue, or not an issue at all? Could it be what's causing the crashing? Don't have a PSU on hand to replace current one with, so would rather find out the cause before I take the computer to the shop.
