RAM Error

Basically I've just installed 4*1gb sticks of corsair PC6400 55512. Now, my ram settings where set to +.2v (=2v) and AUTO timings (55518). Now I ran memtest and received 1 error after about 15 minutes. Could the voltage cause that? I'm running memtest again now. I hope it's ok :/

I've manually set the ram timings to 55512 and voltage to +.1v.

Don't think so, probably just faulty RAM. Try Orthos blend test, and if it fails then remove a stick try again, etc til you narrow down faulty stick
