Had my rig running 4.5 ghz fine running below the 1.4v limit, decided to push it, had it run 8 threads at a bit below 1.7v, reverted to normal, ran fine for ages.
recently decided to push to the 1.5v limit and clocked 4.9ghz 4 threads.
woke up one morning with it blue screening on me everytime. downclocked it to standard and got a boot and login shortly before blue screen again.
So i decided to downclock it, had it running longest at 2.5ghz 4 threads but it would inevitably fail, blue screened quicker at lower clocks
I changed my approach to the downclock and limited the number of cores used, by running 3 cores w/o HT i was able to easily reach a clock of 4.0ghz without any voltage change without any issues of blue screening.
I think I may have blown a core if that is even possible?
Temperature has never been a problem and has only ever reached 80 under extreme clock stress tests.
I have of course tried a reinstall of windows with and without my common drivers/programs etc but the same problem exists.
Just wondered if anyone had an idea as to what may have happened?
Thanks in advance.
