I understand that having 1 gig of ram on one stick allows you to upgrade without having to take any RAM away (as opposed to two 512s) -

but I've heard conflicting reports as to what you should do with an iMac - - I've heard the dual channel action with 2 is faster than using simply one - - -


What do you suggest when customizing an iMac?? The upgrade to 1 gig - (whether 2 512s or 1 gig) is the same price.

Whats the best choice??

For ram to be in dual channel mode, they need to be equal in memory size. You *can* have a 1GB stick and put in another 512, but it will be in single channel mode due to the differing memory sizes.

My view on it is this:


2x512 is possibly cheaper, and definatly faster. But one day im gonna want to have 2gb of ram. So if i have 2x512 sticks, I have one more stick to sell.


I also have 2 sticks which wont likely go wrong at the same time, still leaving me with some RAM while i wait for the new ram to arrive.


I spose its just personal taste.
