I have had a three week relationship with OCZ now, and I would have to say that it has been a very good experience. I bought one stick of 512mb 3500el from a local vendor. It did give me a few problems, so I ordered another stick from googlegear of the same stuff. It seemed even worse! I had a contact with the head guy at OCZ, so I shot him an e-mail. He called me on a Saturday afternoon (day after I emailed him) and I explained my story. TOld him it could be my fault, but I did not think so. He sent me out 2 sticks of the 3700 el which were at my vendor by Wednesday the next week. I echanged the sticks, and everything is fine now. The new sticks came in retail packaging, so I do not know if they were hand picked. I have opened one, and am able to do 464ddr at 2-2-5-2 right out of the box. They may have had prolems in the past, but I would say they are working hard at correcting it. Just my experience. (By the way, I did own one stick of their 2700 stuff awhile back and it ran just fine at the rated speed.)
