Hmmm i should not use Rise of the Tomb raider, seems to have issues with the current 4XX drivers with that game, alt-tabbing causes a reproducible bluescreen.
So you used XMP in one but not the other? I noticed that XMP greatly increased the vccio vccsa voltage's on my board. (Either that or it was the auto settings)
33C ambient?! Holy Cow! Sell PC and invest in AC!!
Unfortunately electrons and heat don’t play well even if you slow it down. By the time you under volt enough to make up for that ambient you might get it to boot and play minesweeper but it’s going to crash and burn on power point.*
I don’t know how you guys do It. I can take that kinda heat for awhile but can’t sit in it non stop. I can’t sleep in anything above 22C. My WC loop max temp alarms at 32C and your ambient is 33C OMG! Hottest I’ve ever seen was Aswan Egypt in the summer where it was hitting 45C+ every day. When I first got there I thought it was abandoned. No one in sight and the AC on the mini bus could not keep up. Went out later and after dark it exploded with people everywhere because at night the temps were dropping dramatically.**
If I had no choice in that environment and it had to be that hot I’d invest in a peltier. **
