    I have been getting kernel panic errors so I ran the Apple hardware test and it gave me the following error:

    4MEM/9/4000000: 0xb92e1b98

    I googled the error and it seems to be pointing to bad ram? I upgraded my iMac with another 8 gigs of RAM about 6 months ago and had no problems until recently.

    How can I find out what the problem is?

    And if it is RAM, how can I find out which RAM chip is the faulty one?

    Thanks

    ----------

    I should add that Techtool pro is not reporting any ram problems

    Take one module out and see if everything is fine on the one module if not swap them. Also alternate the slots. If it works fine on only one of the modules you found your culprit.

    Thanks. I took the two Crucial 4GB modules I upgraded my mac with and replaced with some old stock chips I had from my MBP.

    Ran the hardware test and no problems.

    Crucial are replacing both the modules, as I bought them as a set, under Crucial's lifetime warranty.
