I recently built my own computer. It consits of a Asus A8V Deluxe Motherboard, AMD 64FX 53 processor, TWINX2048-3200PRO 2048MB memory (2 Gig), a Geforce 6800Ultra from BFG, a Creative Audigy 2 ZS Sound Card, and a Promise Fast Track Raid 5 Serial ATA with 4 Western Digital 10k RPM 33Gig Hard Drives. When the Post screen appears, I don't see anything mentioning Dual Channel Mode. When I run SIS the Bandwidth measures 6400 MegaBytes as an estimate. How do I truly know? or what utility should I use to see if Dual Channel really works with my ASUS A8V Motherboard?
