I have 4x16Gb corsair vengeance on my P8ZZ7-V Pro MOBO
I have had it working with all 4 RAM before...
However it's got to the stage where I started getting blue screens.
From trouble shooting It seems all memory runs fine by itself and in pairs. On various slots.
But once 3 or more is used I get OA, 3D and 3B bugchecks
When all 4 are used it doesn't even start.
I have gone into the bios and set everything to default.
Also to a while ago I tried asus auto tune up.
Somtimes after a crash I get a new startup window saying overclocking has failed. Even though i had not attempted one.

Bug check description: This indicates that Microsoft Windows or a kernel-mode driver accessed paged memory at DISPATCH_LEVEL or above.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.
