DDR400 ram on a DDR333 Board

[Neos]

Ordered an MSI Micro ATX board that says it maxs out at 333 on the ram. Can I use DDR400?

I am looking to maybe upgrade the board later and would make better use then of the DDR400.

Thanks for any and all answers. Already picked one guys knowledge box - thought I would get other opinions.

Not sure about all boards, but on alot of them you can.. it will just only run at DDR333 speeds. Can't say this for all mobo/ram combinations, but its pretty goods you can do it.

Yes

That sounds good.

If it means anything, I ordered Kingston ram (256 - 1 stick). All the reviews on New Egg say it is great ram.

The MSI board is the KM4M-V with the Via KM400 chipset.

All opinions welcome.

Thanks

Well IIRC the KM400 is based off of KT400 (only with onboard graphics) which supports a max of 333fsb/Memory.

So if you have DDR400 in there it will just underclock it. I would advise against KVR (kingston Value RAM) as it is poor quality, generally does not OC well, and is very picky about which boards it resides on. I would suggest OCZ, Geil, or Corsair, or Mushkin Value Select. Much better!

yep, your rigth! it could just run @ 333 but no sure if all mobos allow...

Yes, it will.

As I said in your original thread already, KM400 does support running the RAM at 200 MHz. But even if it doesn't (or you choose not to), the RAM will run at lower speeds just as well. It's the mainboard who dictates the frequency, the RAM just has to be fast enough to cope. Slower doesn't matter - as long as you keep it above 83 MHz, which is the specified minimum clock for DDR SDRAM.
