Does the 8 core just ship with 1066MHz RAM or is that all it supports?
Good question. I would imagine that 1333MHz memory is supported by default, assuming the single- and dual-processor daughter cards are all the same, regardless of installed processor(s).
But that only applies to westmere? So then not the quad cores?
As noted on Apple's site
Quad, octo: 1066Mhz
Hex, dodeca: 1333Mhz
These are Intel's specs for the integrated memory controller in the CPU, so don't get your hopes up about getting around them. You can throw it in the bucket with overclocking, since that's basically what it is.
Can 1333 memory operate at 1066 though?
For a variety of reasons I am thinking of getting the bottom spec'd quad core, getting 12GB of after market 1333 memory and then later upgrading to the 3.33 Hex. Makes it harder to do if you also have to switch out the type of memory you have...
Yes. The rated speed is simply the maximum speed you can expect it to. Motherboards/CPU's can throttle the speed down if the system feels like it.
I was curious as to why the Quad Core iMac uses 1333Mhz but the Quad Core MP 1066Mhz?!
Cause Intel said so (CPU specifications).
The odd thing is Intel's specs for that i7 (i7-870 afaik) say to use 1066 RAM...
