    Both sticks are running at 667MHz, individually they both work, but paired I get three beeps, any idea on whats going on?

    One of your memory slots might be faulty. Try a PRAM/SMC reset then make sure you've sat both sticks properly.

    not that sure, but think mac not like odd number in ram if have one stick 1gb other should be 1gb too so if add a 2gb other should match. best check what max ram comp takes.

    Your mac ether takes a total of 4 or 6GB, I can't remember.
    It shouldn't matter that the memory sticks are mismatched. One may be dirty, so try cleaning out the slot with some compressed air.

    Early 2008 takes up to 8gb. Id get a 4gb set (2x 2gb) and try a matching set of ram. If one of your slots is indeed faulty, look for a 4gb 667mhz stick to use in the working one.

    Not true. The max is 6GB for Early 2008 MBP models.

    You can find specs on all Apple products, including maximum RAM:
    • By visiting EveryMac.com: Actual Maximum RAM
    • By using Mactracker
    • By entering your serial number here to find specs for your model. (Be aware that some models can use more RAM than Apple shows. Check EveryMac or MacTracker to verify.)

    You DO realize you're responding to a year old post, right?
