"Yes, A7V8X-X can support DDR400 (PC3200) memory. Due to the chipset
limitation, it can only support 2 banks DDR400, and DDR400 memory only
work with 200/266MHz FSB CPU."
"3 DDR333 memory cause system unstable on A7V8X-X
------------------------------------------------
Problem:
When I install 3 DDR333 (PC2700) DIMMs on A7V8X-X, the system
becomes unstable. But if I remove one, the system works properly. Why?
Answer:
"Due to the chipset limitation, A7V8X-X supports 4 banks DDR333 max. It
means you may have to use 3 single-bank DDR333 DIMMs or 2 single-bank
with one dual-bank DDR333 DIMMs max. Please contact with the memory
manufacturer to confirm with the memory bank Spec. In addition, please
use DDR333 memory in the QVL section on ASUS web or A7V8X-X manual."
