Should I RAM one slot, or two? Huh huh.

I'm thinking about buying a new iMac G5, and I'd like to bump the RAM up to 1GB from the standard 512MB. The Apple customization menu gives you the option of getting 1GB in two DIMMs or one; the latter is $50 more expensive. Is there any performance benefit in having all the RAM in one place, or is it just a question of keeping a slot open?
one piece of advice i can give is this. buy RAM aftermarket! you will save a butt-load of cash. apple is really high for RAM.
now for your question...performace wise its about the same. so if you are just the casual user, keep it stock and just buy a 512 aftermarket. best of luck.

I just got a 20-inch last month and boy, does it rock. I bought a 1 gb stick from Crucial for much less than Apple was charging. It's really easy to install yourself, too. Apple Support has step-by-step instructions on their site.

Second ShawnString. Never buy memory from Apple.

If you have two separate sticks that are both the same size, the iMac switches to a special mode where it reads from both of them at the same time, which in theory works faster, but benchmarks have shown it making no difference whatsoever.
The reason that Apple charges more for a single stick is that:
a) A 1GB stick has to use chips that are twice as dense as those on each 512MB stick. But each of these chips actually costs more than twice as much to make.
b) It leaves the second slot free for upgrading later, which may be a consideration.
I'd buy it with 512MB and add a 512MB stick from Crucial.

Crucial has often been recommended in previous memory-related questions.

OWC is also good for Mac RAM. Crucial can be overpriced, sometimes dramatically. You might be able to get even cheaper without problems if you go even more generic, but everything from OWC has been rock-solid for me, and they know Macs.

And dealram is good for finding those generics that have been tested in your Mac.

(b1trot, I'm aware of the economics of chip manufacturing, I was just using "cost to make" as shorthand for "cost to buy from a manufacturer", which in practical terms is the same thing)

From recent personal experience, and to echo sentiments above, buy the stock iMac with 512, and the money you would save not buying the extra RAM from Apple will almost buy you a 1GB stick aftermarket! I did this, and am v.happy. 512 is just never enough with all the Mac OS X oompa-loompas doing on 'behind the scenes' (Spotlight, Dashboard, etc etc)

I bought my iMac G5 (1.8Ghz 17") with the factory 256 megs, then just bought two 512M sticks from CompUSA (because I was impatient; I paid $99/stick versus the $50/stick I could have gotten it for mailorder). Even with the CompUSA markup it was STILL cheaper than buying the RAM from Apple.
Took the 256M stick out and gave it to a friend.

Buy as little RAM from Apple as possible. Apple charges any where between double and five times actual retail cost. Sometimes even more!
