I am having a problem with dual channel memory mode.
Here's my setup:
Motherboard: Gigabyte S Series MA790X-DS4
CPU: AMD Athlon X2 dual-core 5600+ (Brisbane)
OS: MS Windows XP Pro, Service Pack 3
Memory: I have tried two matching 1GB sticks of Corsair XMS2, OCZ Platinum Rev 2, and Crucial Ballistix. All three sets were DDR2, PC6400, 800 Mhz of dual channel memory. For each one the BIOS configuration was set to 4-4-4-12, 2T, and 2.1 volts per specifications.
I started with just one memory stick in DIMM slot #1. The pc booted without any problems. I inserted a second memory stick in DIMM slot #2 for dual channel mode per instructions in the manufacturer's manual. The pc would not boot. I tried the usual CMOS reset, battery out, etc. etc. The pc would not boot. Thinking I might have a bad memory stick, I tried the memory in a friend's pc. They memory worked in dual channel mode. I also borrowed other matched pairs from friends. They would not work in dual channel mode in my pc. Next, I tried one stick in Dimm slot #1 and a second stick in DIMM slot #3. The pc booted without any problems but the memory was operating in single channel mode. The BIOS, CPU-Z, and other diagnotic utilities all indicate the memory is in single channel mode.
What do I need to do for the memory to operate in dual channel mode? Am I missing something?
