Recently I got a memory manegement blue screen and I just ran memtest today and it failed multiple times most within the same test 3rd hour in today.
Is it possible that a mobo might cause good ram to fail memtest? If not then I know 100% my ram was slowly going bad and was the culprit these past few months!
It all depends. I noticed in your sig that you are overclocking your computer. Have you tried running memtest with stock settings?
