Hello guys! I have a 2.4GHz Intel Imac I was wanting to upgrade the RAM to 3GB. I realise the default Ram in the mac is a 1GB 667 MHz stick, the stick I was sold is a: Geil 2GB 800MHz stick. I have not opened the packaging yet so that I can return it if it does not work. Could someone please let me know if this stick will work successfully in my IMac. Any help would be appreciated - cheers!
