I haven't ever added RAM to a computer before, and I have a couple of questions before I shell out my money. I currently have 2GB.
I know that I need
DDR2 SDRAM-800 MHz

what I'm not sure about is how much I can add, and what I need to buy to do that. The box that my computer came in has information on it saying that it can have up to 4GB of RAM. But I've read some things online that say my model can hold up to 6GB. Which is correct?

Another thing that I'm having trouble understanding is which Ram I buy. I know that there are two ports on the bottom where it's added, but will there be a card in there that I remove? Do I buy 2X2GB so that it's running 4GB or do I buy 1X2GB to add to what's already in my computer to make it 4GB?
what i understand now is that I have 2x1GB. Am I right about that, so that I'll have to replace them both?

Please someone just tell me what I should do to get the best out of my system. I recently purchased a 24" monitor for an extended desktop and M-Audio speakers and I'm getting tired of the spinning wheel whenever I'm running multiple applications and I switch.

Also, where would you suggest I buy from?

iMac8,1, Mac OS X (10.5.7)

    Hi yortington

    Installing ram is fairly straight forward, the biggest problem folks have is ordering incompatible ram and not pressing firmly enough to fully seat when installing the ram.

    OWC sells both a 4 and 6GB kit for your iMac.

    Thank you very much for your help, just one more question.

    What's the difference between the 4GB Upgrade and the 4GB upgrade kit on OWC? I don't think I can afford to go all the way to 6 GB, and the 4GB upgrade kit 114.99 looks tempting, but is the $160 upgrade better?

    edit: nevermind, I figured it out for myself

    The 4GB upgrade is a single 4GB module, which could replace 1 of your 1GB modules giving you 5GB which might be better for opening a lot of smaller applications.

    But, because iMacs support dual channel memory your iMac would actually perform better with the $115 matching 2 x 2 4GB kit when your running large applications.
