    24" Aluminum iMac, 2.4GHz core 2 duo, mid-2007 model.

    I purchased 2 2GB SODIMMs of pc5300 DDR2 RAM to upgrade. I inserted them into my iMac and got the black screen, no beep symptom. I put the original RAM back in, and it boots normally. I tried both of my new SODIMMs in both slots, together with each other, individually, and mixed with the original RAM, and it will not boot.

    Here's the twist. I put one of the new SODIMMs into my Dell Latitude D630, and it works just fine.

    I believe the RAM meets all of Apple's requirements.

    Any ideas what I could try next?

    What RAM is it exactly? It's not odd that it works in your dell and not in your iMac. Apples are finicky.

    Oddly, I can't seem to pull up the exact URL where I bought the RAM, but it was, and here's the SKU and description:

    SKU: g-2gb-ddr2-667-l
    Description: Market Grade - 2 GB PC2-5300 / 667Mhz DDR2 SODIMM

    okay, that's why. stick with a crucial kit, I've never had them not work.

    People seem to be using these with great success for your generation Mac.
    2x2GB for $51.99. No tax outside California and free shipping.

    Also this place has very good mac stuff at fair prices. MacSales (Other World Computing)

    They have a memory configurator and guarantee compatibility.
    I bought some there for my first eMac with no issue.
    Comes out to between 63 & $75 for 2x2GB sticks

    if it were me - i'd return the memory for a refund to 1stchoicememory and go with one of the options suggested here.

    had good results with both owc and crucial.

    all things being equal i'd go crucial as i'm in the uk and if there were any issues it's usually faster to deal with the local post and a few hundred miles vs multiday and 3000-4000 miles ;)

    agreed, i've never had any problems with crucial. Apples are really picky to fault, i'd try to get a refund on the memory you bought. good luck!
