increasing Vcore does not do a thing so it must be my RAM. Also because memtest gives errors before it reaches 1% of the test.
Silly thing is that the RAM is running well below specs. I got the OCZ PC3-10666 ReaperX HPC Enhanced Bandwidth 2x2Gb kit which should be able to handle 1333Mhz 6-5-5-20 timings at 1,8v and I have it now at 1200Mhz 6-6-5-20 (2T) and it fails.

Tried to increase NB voltage but no effect. What do you guys think I should look for in solving this?
try playing around with the finer memory timings. even on auto one of them could be too tight for your ram.
also try playing with skews. there are a few ideas a couple of pages back.
