I ran my 3700EB sticks for over a year at 3v and never had any problems. I dumped these for the 2gb ballistix kit. After all the stories, I am just waiting for them to go tits up. I am stable at 284 right now with 2.6v. I am hoping this low voltage will keep them alive. FWIW I never saw a gain when overvolting them (up to 3v) while I was first dialing in my overclock on the ballistix and Opteron.
I am glad they have a lifetime warranty.....
