*cough* http://forums.rojakpot.com/showthread.php?t=20199 I also got the VX pretty high too.. Ballistix did ok too.. So thats what, UTT, TCCD, micron chips... Also used UCC too. I've used OCZ, GSkill, and Crucial. All of them with top notch support.
Yeah, not sure about Corsair specifically but 2GB ktis mostly use Samsung UCCC, Infineon chips and probably some Micron ones too.
