I've had 3 hardware issues with my iMac G5 this month....the logic board is in the shop waiting to be replaced right now. I may be getting a replacement Mac but I was curious about the RAM. Is the RAM used in the Rev B iMac G5's the same as what is used in the Rev A iMac G5's? I spent $200 on a 1GB stick of RAM for my Rev A and if Apple ends up replacing it with a Rev B I'd like it to still work so I do not have to sell it and buy another stick. Thanks for any help.
