iMac RAM Upgrade in the Future?

[joemama2413]

I am the proud owner of a new Al iMac 2.8ghz, 4gb of RAM, 256 mb graphics. If, in the future, Apple comes out with an iMac with say, 6gb of RAM with 3 in each slot, would I be able to upgrade the RAM in my iMac to 6gb?

I do not have a concrete answer here, but I believe the Santa Rosa Chipset caps off the max at 4.

The Santa Rosa chipset allows for a 800 MHZ bus yet the RAM is only 667? Any chance that will be ungraded?

No.
Your machine is limited to what the hardware memory controller will recognize.
(and you'll never see a 3 Gb RAM module - RAM sizes go up by multiples of 2: 256 - 512 - 1024 - 2048 - 4096)

hi to all

This is my first post

I have some questions
I just bought the iMac 24” 2.4GHz with 1GB at 667MHz

I am thinking in upgrading it to 4GB of RAM
Is it possible to use 800MHz RAM or the machine dont support more than 667MHz speed?!!!

the second question, does the memory work as Dual-Memeory on iMac?!!
or they wont even if i installed identical pairs
