I have a couple memory modules from my previous iMac late 2009 -Intel Core 2 Duo 3.1GHz- and I just got my 27" i5 Quad Core this week, and I was thinking if those memory modules (Original) are compatible with the one I have now, so I dont take them to the garbage.
No, the 2009 uses PC3-8500 1066MHz modules and the new iMac uses PC3-10600 1333MHz modules. see > iMac: Memory specifications and upgrades
Besides you should always keep your factory modules in a safe place for troubleshooting and/or incase the iMac ever needs to go in for service
Regardless of it being the same or not, NEVER use old or cheap RAM! It is just asking for trouble!
Thanks, I was thinking it was compatible for some reason, then just update with new ones and that's it !
Altough the memory says PC3-8500S it has an S at the end.
Is my iMac Late 2009 Core 2 duo 3.1 Ghz Memory compatible with i5 Quad core late 2011?
