What is the difference from registered ram and unbuffered ram? I know I want duel channled, PC3200, 400mhz, what should I look for in the voltage, bandwidth, Cas latency, error checking, organization? Are some of those just crap that I don't half to worry about? And im guessing Ill proble pick between corsair, kingston. So any suggestions on picking memory for a Asus A8V deluxe, Geforce 6800 Ultra 256mb, Amd Athlong 3500.
