ASUS MOBO Issues

[rmslonejr]

Hello,
Have ASUS M4A79XTD-EVO, which mfg claims to have 8+2 Phase power. Have had random BSOD till now won't POST at all. Bios is latest, GSKILL 1333 RAM (4x4GB) runs Memtest86 v4.0 four hours w/o a fault. Have confirmed all MB drivers. Have tried 2 HDD's, 4 graphics cards, 0, 1,2,3 and 4 sticks of RAM to no avail. Currently using OCZ 500W PSU with XFX 6870 graphics card.

Wondering: Does this 8+2 Phase mobo power require a special PSU? Or, can you give me something else to fret about?

Is your CPU OC'd?

No oc. CPU and RAM are both at default. Memtest says AM is 1066

you are using 4 graphic cards? are they all 6870? if thats the case, 500W is no where near enough. you need a 1000W PSU minimum! Have you had any progress over the weekend?
