I recently purchased 2 sets (total of 2 gigs) of this type of DDR400 memory.

Currently my motherboard is a Asus A8v-Deluxe motherboard, with a 3500+ (soon to be a fx-55 San Diego core )

anyways for some reason my memory only reads at DDR333, i have tested the memory one by one and they all work..Anyone know how i can find out what is wrong? Or what i need to tweak/change to get it to go into dual channel mode? (how can i tell by the way)

Could this be due to a bad MOBO?

thanks to everyone who helps
