blockhead78 :
with everything set to stock/auto, use hwinfo
run a quick stress test and check what frequencies the cores are running at, the vcore value and what temps the cores and cpu package are being reported
Also, is your bios running the latest version?
Sorry I took so long, couldn't get the machine to boot again and Toms wouldn't load up on my phone
Anyway, I might have finally got some progress, after a second reseat of the CPU, and the heatsink barley on, I think I might finally have a stable system on stock. The fastest it completed POST and booted so far. Stressing it with Adia64 at the moment.
Everything looks stock in HWinfo as well, BIOS on the latest version too.
EDIT:
10 minutes of stressing and I can still use the system pretty normal without Chrome lagging like I'd expect it to
Anyways temps still going up, so I think I'll wait around for them to flatten a little. I have observed frequently large temperature differences between the cores though of around 10C, possible result of a lose cooler I guess, so I might tighten it a tad more, but I don't want to screw it all up again.
