    Ok so I just recieved my 4gs of ram from Crucial and attempted to install them. I was able to get them situated fine but when I tried to turn on my computer it refused to start correctly. It would start up, but the screen would remain blank. So I removed the new ram and replaced it with my old ram. My imac started up fine after this.

    Now I am reviewing my receipt and it says the following under product description:

    Upgrade for a Apple iMac 2.4 GHz Intel Core 2 Duo (20-inch) MB323LL/A System 2-2GB 200Pin Kit of 2 CT25664AC800.A16F

    That's where I noticed something. Everything on the description seems to fit my mac except for the "MB323LL/A". My iMac is one of the late 2007 iMacs, and I am worried that I ordered one of the 2008 20" iMac memory. It seems like this wouldnt be a problem since both my iMac and the 2008 model have a 2.4 GHz processor.

    Does anyone have any thoughts or insite on to what might have gone wrong? Did I order the wrong ram? Should it still work if I did?

    According to Mactracker a 20" iMac from mid to late 2007 has 200 pin PC2-5300 (667Mhz) DDR2 SO-DIMM.
    A 20" iMac from early 2008 has 200 pin PC2-6400 (800Mhz) DDR2 SO-DIMM.

    Yeah, the MB323LL/A is the 2008 model.
