    Specs:
    24" IMAC 2.8Mhz Duo Core Extreme
    Installed 4GB RAM (2 x 2GB) on iMac 24" 2.8Mhz Extreme and system hangs.
    Hello everybody,
    I am new to the the wonderful world of MACs and I am seeking any kind souls out there tha can help me solve my misery.
    My IMAC specs are as such:
    24" IMAC with 2.8Mhz Duo Core Extreme, 2GB RAM (Upgradable to 4GB) Bought in July 08.
    After getting 2 x 2GB RAM (Kingston 800Mhz DDR SDRAM PC6400) to upgrade from my 2GB, the system refuse to boot up. (BLACK SCREEN)
    However, if i installed only 1 x 2GB RAM n 1 x 1GB RAM, the system boot up normally and indicate 3GB of RAM (667Mhz DDR2 SDRAM).
    Misery Misery Misery
    Any experts out there please advise.

    15" MBP, Core i7/2GHz, 8GB RAM, 480GB Crucial M500 SSD
    Very simple, you have the wrong kind of memory. Your machine takes PC2-5300 in 2GB (max) modules, the 800Mhz modules are not compatible.
    Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!
