Random bluescreens F3-12800CL9D-8GBRL

[apathy]

OK, i was getting random bluescreens on my system a couple weeks ago. I came to this forum and searched around and followed some suggestions from users here, i ran memtest for about 9 hours and it did about 10 passes with no errors, i raised the voltage of my ram by .05v so it's now 1.55v and the bluescreens seemed to go away..until now. Now i'm getting random bluescreens again. Should i test my memory again? i already did it for 9 hours and no errors, should i maybe up the voltage more? or is there another voltage setting to try? Any help is much appreciated.

Check that you have the latest BIOS...if that doesn't help might raise the VCCIO voltage a tad (.04 or so), could also check that all hardware drivers are up to date....if continues write down the BSOD Error and let us know

I can't find the VCCIO on the voltage page. Can you tell me which one i need to edit?

QPI/VTT on this motherboard - some it's VCCIO, CPU/NB, NB, etc...it's the voltage to the Memory Controller
