My iMac has been having problems (see https://forums.macrumors.com/threads/568012/), and apple is sending me a new 2.8Ghz 24" iMac. I was initially happy, but now I see that the new iMacs use PC2-6400 (800 MHz) RAM. I have 4GB of aftermarket ram in my current mid-2007 iMac, which is PC2-5300 (667 MHz) - can I install this in the new iMac, and it will just operate at a slower speed?
Thanks!
Thanks!
