Asus A7N8X & Corsair TWIN2048 BIOS Settings

Recommended Posts

Motherboard: Asus A7N8X Deluxe

CPU: AMD Athlon XP 3200+ 2.2 GHz 400 FSB

Memory:

1. Corsair TWINX2048-3200C2PT 2GB DDR400 installed in DIMM1/DIMM2 slots

2. Corsair CMX1024-3200C2PT 1GB DDR400 XMS3200 installed in DIMM3 slot

 

1. Will the above configuration work in Double Data Rate mode or does the extra memory in the DIMM3 slot make the system run at Single Data Rate?

 

2. Are these the correct BIOS settings for the above configuration?
