the motherboard is rev1 with bios f6 I tried running memory at 1333 8,8,8,24 and 1600 9,9,9,24(I am not sure on the last number it maybe 22 I used what was recommended on other forums) and increasing voltage to 1.6 at both speeds. I did test the memory ind. in the slot closest to the cpu with memtest and windows memory. 1 time I did get 1 error with memtest running at 1600. I have the module out of my computer now It still will blue screen. I tried a Ubuntu boot disk to make sure its not a driver in windows and got a unknown error and have clean installed windows 7 pro. That is why I think its memory,cpu or motherboard that is bad. The memory I have is F3-12800CL9D-4GBNQ if I slow the memory down to 1066 my computer won't boot.
Most of the blue screens are memory_management or IRQL_NOT_LESS_OR_EQUAL and 1 ATTEMPTED_WRITE_TO_READONLY_MEMORY
