After seeing many negative posts about OCZ memory I was a bit leery of buying it...but after 2 RMAs for Kingmax PC150 that wouldn't even do 150mhz 3-3-3 without errors I decided to try the OCZ Performance 150cl2. Runs flawlessly in my system @153mhz 2-2-2 and upped my 3Dmark2001 score by 200 pts! The stick I received had 7ns Micron chips on it. Just wanted to post a positive OCZ experience for what it's worth...
