    Just bought a new iMac with 24" screen, running 2.4Ghz with 1GB of memory.

    The local Apple store did not have more memory, so I took the machine with the standard 1GB. Would like to upgrade to (at least) 2GB.

    I have heard that a lot of the 3rd party memory is unreliable and can even crash the iMac. Can anyone recommend a reliable brand of memory for my machine?

    Thanks for your comments.

    Regards

    Is it better to have 2 sticks the same or does it make no difference if you have for example 1 gig + 2 gig sticks?

    Umm, you order a product, just like people in the States ... ?

    Actually I'm not sure about Britain specifically, but I live in Japan and had no problems ordering my 4GB RAM upgrade using a Japanese issued Visa. YMMV but I seem to recall seeing quite a big list of countries when I was checking out ... ;)

    Thanks for your comments.

    I have purchased a 2GB module for my 24" 2.4GHz iMac.

    This will be used in the #2 slot to provide 3GB total on this machine.

    Looking at the MacRumors instructions on installationof memory, it is strongly suggested that one run a thorough memory test after installation. The recommended tool is something called "memtest."

    Has anyone else used this tool? Although I have tons of hardware and Windows experience, I am new to the Mac. Is this test difficult or confusing ?

    Thanks for your help.

    Received a 2GB memory module for my 24" iMac yesterday afternoon from OWC.

    Installed without incident.

    Restarted computer and everything seemed to run fine.

    Ran 3 cycles of Rember and the end result was "all tests passed."

    Ran a second set of 3 cycles with Rember this morning with the same results, "all tests passed."

    I am assuming that the memory is okay based on these test results.

    Will I need to retest at some point in the future to determine if the memory has started losing bits or bytes with age?

    I ordered from OWC when I lived in the UK and also from Spain. No a problem at all. They requested that I complete a credit card verification form before they will deliver, but once that is done everything is easy. You may have to watch out for import duties, although saying that it still seems to be cheaper than buying it in the UK.

    Please read the MR Guide , we have covered this many times already.

    Matching RAM gets a general 6% - 8% performance boost -- more in the machines with integrated video (cos it speeds up the shared video memory as well), less on the machines with dedicated Video.

    If it is a choice between 2 Gb matching and 3 Gb non matching, IF you regularly multitask, use Photoshop, digital video or digital audio or have 1000's of photos in iPhoto, then the additional 1 Gb of RAM will give more performance than the 6% - 8% you lose by using unmatched RAM. So: for light use, matching RAM is better, for any heavy use, 3 Gb unmatched is better.

    If you can afford to go 2 x 2 Gb in a Core2Duo machine, then you get matching RAM dual channel speeds, and the maxium RAM load -- 3.3 Gb usable RAM in Core2Duo machines and 4 Gb usable RAM in Core2Duo Santa Rosa models.
