Had to send some Corsair pc4000pt 2x512 memory on RMA. Had errors when running memtest and failing blend in prime95. My overclocks were not stable at all. So question is what kind of memory do i get instead. I am running winchester 3200, Gigabyte K8NS Ultra 939 and using a geforce gt6600 agp PNY card. I want the best performance i can get with what ive got. Thing is the store I got the memory from ONLY deal with Corsair, or Kingston so was wondering what to get from either these 2 manufacturers.
