OC E6850

Hey guys am having a hell of a time trying to get my system stable with Vista Ultimate 64, On XP Pro 32 my system was stable, but now am getting error on orthos and prime 95, either ill bsod or it will just give me an error, Most times right away or with in ten min of testing. Am thinking its a ram issue. I sent in all 4 1 gig sticks of DDR2 6400 OCZ said they where fine, Sent in my mobo and evga said it was fine. Evga also told that the 680i have an issue with having all 4 dimms use so i went out and bought 2x2gb sticks of ocz DDR2 8000 and am still having the issues

when ever i go into the bios and place the ram voltage to 2.1V which is the voltage needed from the ocz website and timmings of 5-4-4-15 2t i have the ram sli enabled or disabled, ill go back in and stress test with no over clock and ill get an error or bsod but when ever i place the voltages at auto it works fine for 58 min then i get an error 8 times out 10 the other 2 i bsod and this is with both stock and overclocking settings.

can anyone please help me with this issue??

Thanks

Yeah it is bad idea to run all four memory populated ,
What are running exactly blend prime or small FTT ?
If Blend , then reboot your computer download memtest and let it pass 10 test if there is no memory error then this is the CPu which require more Vcore
If Small FTT .
Then in 90 % this is the CPU requiring more voltage or better cooling .
ANd yes stability is harder under X64 bit system
