DO NOT, i repeat, DO NOT buy that OCZ memory. Particularly if you plan on doing any overclocking. I just bought a set from newegg and BOTH STICKS were defective. Had to return it. Ran tests independenty on both sticks. Also uses a totally crappo IC - Infineon - if you are lucky. Stock latencies only good at 200MHz. OCZ themselves does not even report stability at those latencies on my mobo (Lanparty NF4 - most popular NF4 mobo) and recommend you run at 2-3-2-8 =/ ... There are better and cheaper options out there. This is a very disappointing offering from OCZ. They really dropped the ball on this one. Most people I have spoken to have returned them. Now me too.
I am trading them in for the g.skill ZX kit. Last I checked it was about $215 at newegg.
