I have an MSI 645 Combo MOBO and I want to up grade my 256MB pc2700 to a 2700 512, and I was just wondering if I could put a RAM with the pc number 3200 eventhough my MOBO doent support it, would it just clock it down or not work at all???
Cheers

found this ram tool but your board is not listed.
they do have an e-mail for special requests:

plus here is a google search for browsing:

running 3200 ram on 2700 board

hope this is some help
