RAM upgrade mid 2007 Alu iMac

[Bolteh]

I have a mid 2007 Alu iMac (2.8Ghz, 24") that holds 2GB 667MHz DDR2 SDRAM, but I want to upgrade the RAM to 4GB now because it's starting to show age.

So the logical solution would be to get another stick of 2GB 667MHz DDR2 SDRAM and have a total of 4Gb (the maximum as far as I know?). But, I was wondering if you can actually throw completely new 4GB of 800MHz in there(or even more?), or won't the mainboard be able to handle that?

 

[Cave Man]

You can put 6 gb in your iMac.

Oh, the supportpage on apple.com states that the mid 2007 Alu iMacs can only handle 4GB max.

Apple has lied about maximum RAM for decades.

The 2GB of RAM will probably consist of 2x1GB RAM sticks, and not one 2GB stick.
So you either have to buy 2x2GB of RAM or just buy a single 4GB RAM stick.
I don't know about putting higher frequency RAM in there though.
Have a look with MRoogle.

Your iMac has a Santa Rosa chipset, therefore it can address 6 gb of RAM. My MBP has this same chipset and I have 6 gb in it. Here's what you need.
