We don't know yet. Most people are betting that Apple is delivering RAM of CAS timing CL-3, and that if you match the size and CL-3 then you will have access to dual channel.
Some even surmise that if the CAS timing is different, that the G5 iMac could still do dual channel -- albeit at the slower timing. This one is pure conjecture, and we have to wait for reports from the field...
Most iMac owners will never know or care about single vs. dual channel. It was smart of Apple to enable any combination of sticks in the two slots.

How about this: My 1.8 20" is shipping with 256 ram. I use after effects and Final Cut and so could use every little bit... but I'm low on funds. Here's what I can afford: buy 1 Gb to combine with my 256... or buy 2 512 and lose the 256- I can't afford 2 1 Gb.... If it runs better on matched pairs, any idea on which of these configs would be superior?
I know no one knows for sure, but perhaps an educated guess.

If you are pushing the iMac to do that, I'd shoot eventually to max out the memory at 2GB. Thus, I'd buy the 1GB, live with the performance hit of single channel memory for the time being, and save your pennies to buy a second 1GB stick.
Thank you Corbin for those pictures, and congratulations on the new iMac. Looks great! Can you give us your impression of the computer in general. How do you find the audio performance?corbin_a2 said:
Oh, and may I ask if you use that Apple ][c?

Faster then my G3 AIO
Is there a way to do a benchmark? I don't have any software for it. All and all I am pleased with it so far. I don't think I can do a real review untill I use it more then 1 hr. But everything seems good so far. I like the size and the screen is nice and bright. Put a DVD in and it look excelent! All good so far.
commercials
Since the new imacs are shipping, from a historical standpoint when can we begin to see the promotional ads?

Yes, it's sad... (spent all my money waiting for those dual 3Ghz rev B G5's to be released last december as everyone seemed so sure they would be) but I've had the patience to render 15 minute projects on an 800 emac and even a 400 imac, so this should seem like nothin.
I'm buyin' the 1 GB now.

Go to www.cinebench.com and download the cinebench 2003 software (the G5 version). Run that and post the scores. You can save the scores as a text file, so just post the contents of that file.

That is so sweet!
I gotta go find my vintage Apples (a Plus, a classic and an Apple ][) and do something similar with my current setup!
Congratulations and thank you for the pix.

I'm dealing with this dilemma right now. I ordered a 20inch iMac with a single 512mb chip. I was going to go ahead and order another 512mb separately, but I read in another forum that I should wait and see what the CAS timing is on the chip installed by Apple. How do I figure that out once I get my iMac?

According to this:
https://www.macrumors.com/pages/2004/07/20040702194153.shtml
the 2.5 Ghz G5 does 356-CPU on the single CPU rendering test.
that is, it scales almost linearly in with CPU- frequency (basically getting 140 per GHz).
It shows that the 600 Mhz FSB speed does not limit the new iMac G5 design
PS. Mine is shipping to Norway too!!!!!!!
Congrats
Congrats to everyone who received their iMac G5s today and those who are going to tomorrow. Good luck sleeping. I don't know what the CineBench results mean, but I am sure someone will interpret/attack/defend/re-interpret soon enough. I hope that the results are what everyone was hoping for. I won't be the first person with a new imac but I'll get mine soon enough.
I am curious about how well the speakers work though. Most people expand upon the stock setup anyway but I am curious to see how well it works. Maybe Apple will develop it's own line of innovative peripherals down the line.
