Why can I only use 2x400DDR or 4x333DDR with MSI Diamond?

[wal]

Looking at the spec sheet for MSI Diamond and the type memory it supports. Kingston site says maximum memory is;

2GB using 400MHz DDR modules
4GB using 333MHz or 266MHz DDR modules

Am I at a disadvantage by bying 2 x 1G 400 sticks as appossed to 4x1G 333? I dont understand why this is the case yet it looks like I can have more ram but I have to use slower ram.

Edit: Ok after a bit of research it seems as though using 2x1Gb sticks is much better for performance oem mode and even better for overclocking. I was originally going to buy only 1 x 1GB and upgrade to 2GB in the future but I would be disadvantaged because i would either have to by another single channel module or swap the first stick and buy 2 dual channel sticks.

So If I understand my brief research thus far I should really just buy 2 x 1GB dual channel DDR 400 sticks which should keep me happy for a long time.

I just went through the similar situation. go for the 2x1 gb stciks in dual channel. look at the ocz gold gtx series stick. i have them and have never been disappointed.[/code]

You're on the right track, this is just like my last post about this motherboard.

OK, WELL I HAVE 1 STICK OF OCZ512400R3...IF I GET ANOTHER CAN I RUN THEM AS DUAL CHANNEL?
