Re: Gigabyte GA-X79-UD3 Core i7 3820 Random Freeze
Have you looked at the event viewer to see if anything was captured (or errors prior) from the crash. sometimes it will point to an issue and then hard crash prior to a BSOD being able to respond.
and have you tried running the system at stock speeds at all to see if the problem is replicated when no overclock was present?
I recently had an issue where my threads (1-8) would randomly "lose power", this was according to the event viewer system tab. this would cause a similar issue as you are describing... but the issue was only present when I overclocked, didn't happen when the CPU was at stock speeds. I could game, bench... all fine... do nothing or browse the web and boom... hard lock. in my case I had speedstep disabled, 3 years never an issue until recently.
