i just got my a1 revision evga, its good so far, but its giving me overclocking issues. stable for hours and than not stable, i am in the same boat as you, i am going sli and the only reason i didnt buy the striker is because i didnt think they clocked very high with quad cores.

i had an ip-35 pro before the evga and that one did 3.6 with 1.39v loaded and 1.5v set in bios, that was prime stable for 8 hours. and the evga wants more voltage for some reason, i was able to prime at the same settings as my ip-35 pro for about an hour and after that it wanted more voltage, right now i am testing at 3.2, it wants the same voltage to run at 3.2 that it did at 3.4 with my ip-35 pro.

Could it be because i am using 4-pin to 8pin adaptor?

i do have a 8 pin cable but since it wont reach the top of my board because my psu is on the bottom. i just ordered an 8 pin to 8pin extension cable from newegg to see if that makes any difference. or i might just return mine to frys and order a striker from newegg, i guess they have finally fixed the quad core issue with those, i am surprised because asus wouldnt just sit around and let these board overclock like crap with quads.

where did you get yours?
