dear jinino,

[but I think you can only use one stick of ram. From www.ocworkbench.com, some people say they can use two sticks of DDR400, and I am not sure it is true or not]

So said, you mean that this board doesn't have dual-channel function?

alas..., after browsing DFI website, the answer is dispointing.

So, maybe I have to turn to NF7 or LanParty series.

Thank you for your valuable advise.
