Hi All,

I am considering attempting upgrading the CPU, RAM and HD in my iMac. I recently upgraded my Mac Mini to a T7600 2.33Ghz C2D.

Upon searching the net, I see the iMac CPU is indeed upgradeable, as is the RAM and HD. Now, the RAM and HD I have no real issues about, however I am unsure as to the maximum speed processor I can put in my iMac.

I have the low-end 20" Rev C model listed here...

http://guides.macrumors.com/iMac_(Intel)#Rev._C

... Which is an Intel Core 2 Duo 2.0 GHz 800 MHz system bus, 4 MB shared L2 cache.

My first question is what socket mainboard does this model of iMac have? I have gathered it is socket-M. Is this correct? If so, what processors are Apple using in the 2.4GHz and 2.8Ghz models of the same revision? In the table below...

http://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors#.22Merom.22_.28standard-voltage.2C_65_nm.29

...the fastest socket-M listed is the 2.33Ghz T7600 I stuck in my mini.

Which begs the question... Is the mainboard consistent across all revC iMacs described in my first link from Macrumours, and if so, what is the fastest chip I can upgrade my iMac to?

Thanks in advance for your help, I am mighty confused indeed!

Right, I've figured out that actually, my iMac is a socket P mainboard.

I currently therefore have the Core2Duo T7300 2Ghz/4mb/800FSB chip in.

Chips I am looking at transplanting into this include the following...

Merom - 65nm / 35W
T7700 - 2.4Ghz - 4Mb Cache - 800 FSB
T7800 - 2.6GHz - 4Mb Cache - 800 FSB
Penryn - 45nm / 35W
T9500 - 2.6Ghz - 6Mb Cache - 800 FSB
Merom XE - 65nm / 44W
X7800 - 2.6Ghz - 4Mb Cache - 800 FSB
X7900 - 2.8Ghz - 4Mb Cache - 800 FSB
Penryn XE - 45nm / 44W
X9000 - 2.8Ghz - 6Mb Cache - 800 FSB

the X7900 is the CPU in the current top of the range 24" 2.8Ghz iMac, so I am pretty sure that will work. Someone on the net managed to put an X9000 in their iMac, but it only showed at 400Mhz due to the unlocked multiplier.

What are people's thoughts, if any?
