Hey guys, thanks for looking into my problem.
What I've been having is some problems with my memory, I have 2 4GB sticks of Corsair Vengeance RAM (2133) running at 1333mhz at auto settings in BIOS.
Alongside with those I (tried to) have 2 4GB sticks of Corsair RAM of which I am unfortunately not sure about the stock speed, I believe 1366 or 1333 since they look like simple cards.

When they're all installed on my motherboard (ASUS ROG Crosshair V Formula-Z) they run at 1333mhz.
When I only have 2 of the same sticks installed I have no problems, but when I install all 16GB together on my motherboard it seems to be unstable. Sometimes I have no problems and sometimes I tend to get a BSOD right after booting.

Is this fixable? Or should I just give up and keep using only 8GB of RAM?

Thanks for looking into this!
 
Solution
Can try stabilizing at 1333 by adding + 0.05 to the DRAM voltage (prob to 1.55) and add + 0.10 to the CPU/NB, AMD CPUs generally need that to the CPU/NB for 4 sticks, and manually set timings at 9-9-9-27
