Ram Timing Issue When using 2 sets of 2x4Gb RAM

[nothix9]

Hi there.

My build is
MOBO - Sabretooth z77
CPU - I7 3770K
RAM - corsair vengeance 2x4gb CMZ8GX3M2A1866C9

everything is running fine on xmp 1600 then after a year i decided to go 16gb and bought another set of the ram corsair vengeance 2x4gb same model.

default timing is 9-10-9-27

so Im now running 2 sets 2x4gb (16gb) and Im using all slots. I encountered varios BSOD and crashes since then.

I tried to put dram voltage to 1.575
still having issues. Any tips suggestion?

Make sure all timings are the same and frequency also. You shouldn't really put two different RAM sets together even if they are the same model.

The Cat's right, never a good idea to mix sets, but since you have them, set them manually to 1866, CR to 2T, DRAM voltage to 1.6, and raise VCCSA to 1.06 and give it a try, (may have to go to 1.1, but start at the lower 1.06)
