I've been a Mushkin customer for several years and have always been completely satisfied with it's performance, not to mention great customer service. Well a couple of weeks ago I decided I needed another 256 stick of their PC3200. As expected I was no longer able to run it as fast with the second stick. So I gave in and purchased a 512 stick of Corsair PC3200 2 3 3. Well the performance has exceeded all my expectations. It actually ran at 210fsb at 222 before failing Prime95 after 15 minutes. Still pretty awesome in my opinion. I don't get too excited about this kinda stuff anymore...., however I'm running this stuff right now at 440ddr at 2 3 3 6 without a hitch................trully some great stuff!!
