Okay finally got some time the last couple of nights and man......
these stick are pissing me off even stock settings they fail memtest86+ after 7 hours IDK....?
I have tightened, loosened the timings , lowered raised the volts dropped to 2t, switched slots. going to have to pull 1 and test some more I hope to hell I dont have a bad stick.
It fails on test#8 BTW which was a bad OC on my OCZ platinums but these are rated ddr500.
IDK any suggestions something I am overlooking? Had my ocz for years and I knew exactly what they would do so it's been awhile since I have had to play this game with my ram.
Edit:
Doh
Forgot to inclued my specs:
3800 x-2 @ 1500, takes it out of the equation
EVGA NF-41 mobo
2x1 gig Muskin PC-4000 Redline
XFX 7600GT XXX
600w FSP Epsilon PSU
ect, ect, ect.
Also 2400 is stable @ stock timings for like 10 hours.....
Edit

kay getting some settings from muskins forum for a64 tweaker, if they work then it's probably a MOBO issue rather than RAM, I did just flash my BIOS before I installed the new RAM.......
Hmmmmmmm.......................
