Q: Is my iMac Late 2009 Core 2 duo 3.1 Ghz Memory compatible with i5 Quad core late 2011?

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!
