The one question I have is that the i7 I purchased is configured with 2x2GB of 1333MHz memory (4GB total). I already purchased 2x4GB 1066MHz of memory that was supposed to go into the original system (for a total of 12GB). Does anyone know if the OS is smart enough to be able to mix the 4GB of 1333 and 8GB of 1066, or am I going back ebay?
Congrats on your new iMac...twice over!
Well, I don't think it depends on OS X as to whether or not the different type of RAM will work. I think it depends solely on the CPU. Please, anyone, correct me if I'm wrong. (@dfiler: You seem very knowledgable about this. Thanks for the advice!)
At any rate, I'm in the same boat as you. I took out the 4GB (2x2GB) DDR3-1333 chips, and replaced them with, gasp, 16GB (4x4GB) DDR3-1066 modules. Before I swapped the memory out, I decided to play around with it using the 4GB DDR3-1333's, and when I picked up my jaw off the floor after the incredible display had me mesmerized for a good 15 minutes (that's after 2 1/2 weeks on the 21.5" iMac! Yes, it's that amazing!), I pulled the chips that came with it and put in all four of my DDR3-1066 ones. After turning it back on, it booted the system back up with no problems and I've been configuring everything for the last several hours.
The service at the Apple store was excellent as usual. The manager quickly waived any and all restocking fees and simply let me swap out my 2 1/2 week-old 21.5" model for a brand spanking new 27" one. He even hooked me up with a $100 discount.
I'm loving this thing!
