I can have a perfectly stable OC, tested with Linx, Prime 95 etc. After the PC sits overnight switched off, upon a restart the next day it is terribly unstable, and can BSOD just sitting at desktop. Adjusting Vtt, usually lowering it, re-establishes stability.
Anyone else experience this?
I am using BIOS 1406, and have tried 2 different CPU's and the issue happens with both of them so its not CPU related. I have reseated the CPU and reseated the Vtt daughter board, neither helped.
EDIT - I am thinking perhaps the badly designed Vtt daughter board may be overheating or the pins that connect it to the mainboard have bad contact, but I'm not sure why this would suddenly happen on a cold restart and not during hours of benching. Could also be a BIOS issue, but since BIOS1406 is quite a few BIOSes in, they should have sorted any major bugs out by now.
