    Should be OK, the 3200 will clock down to the 2700

    well if your machine supports 2700 it will take 3200 but, it will run at 2700

    now if you already have ram its not reccomended to mix and match different speeds or brands

    Since when have you abided by a 'recommendation' ? ;)

    If it doesn't catch fire, it's all good :)

    Unless you are running dual channel DDR you can stuff anything you want into any machine. It will just run at the speed of the slowest stick. (Exception, some machines require you to use buffered RAM if all 4 slots are populated.)

    Some stupider bioses may lock up if you put a fast stick in the first slot becasue they don't look at the speed ratings for all the sticks. Just put the slowest stick in the first slot if this happens.

    If you really want to keep the older RAM in there (I didn't, though my old was XMS 2400), just pair the DIMMs appropriately. AKA, don't put a DDR 2700 and a DDR 3200 DIMM in the same bank, keep both of the same type/speed in their own respective banks, and then it should go OK, albeit slower.
