Hi all
My friend has has got AMD Athlon 64 and DDR 400 memory.In CPU-Z it shows bus speed 200 mhz.Now is this normal?Shouldn't that CPU work at 400 mhz?
Thanks

Thats normal. DDR400 runs at 200MHz but can send/receive info on the up and down cycles so in effect it runs at 400MHZ. Thats what the DDR stands for.

Double Data Rate...so, 2*200=400 (DDR 400)

Basically what he said...
