I've got a bit of a dilemna. I just bought 512mb of Crucial PC3200 to go with my Asus a7n8x. To those of you who suggested it, it works great! I still have a 512mb stick of SimpleTech PC3200 and I'm not too sure what to do with it. I know that the Crucial timings are CL=3 but I don't know what the SimpleTech is. Now, here's the question: Obviously I get better performance with the Crucial over the SimpleTech. However, would my performance improve even more if I install my SimpleTech alongside the Crucial in dual-channel mode? It seems to me that 1gig would be faster than 512mb hands down, but would the Simpletech be holding the Crucial back? I'm only running an Athlon XP 2200+ (266mhz FSB) right now, along with a XFX GeForce 6600GT AGP and SB Audigy 2. Thanks!
