hi. I have a M754LMR Mainboard and need to know if it will support a 1gig celeron. I went to the store where I bought my computer from and they said"oh yeah no prob", but not really sure of these great words of wisdom I looked up boards web site and it says hat it only support to 600. so I phoned the store and talked to owner and his reasoning for the discrepancies was that the owner of thaw web site don't update it. So to make long story even longer I would like to know if anybody has done this.
