First a bit of luck. After being bumped back twice on my order, I called the local apple store, (Walt Whitman, Long Island) and they had one that just came in. I grabbed it sept. 8th, stock. (They haven't gotten another in since I believe). I immediately added 3MB of crucial ram (512 chips) and a second internal drive. From the first time I used it, it would put itself to sleep, usually after a fan rush, unpredictably in that it could be during CPU intense activities or web browsing. So...back to the Store where I got FANTASTIC service. (Thanks Sarah if you read here). problem turned out to be a bad processor. More so, the first replacement sent by apple was a totally DOA processor that wouldn't even boot up. The second replacement did the trick.

Everything has been working fine for several days. I love the machine. (I've owned them all from a classic on down). well worth the trouble, but, it does sound like there are some squirly dual 2.5 processors out there. best.....Peter

Glas to hear you got good service and finally got a good G5. I've just started saving up to buy a G5 hopefully this time next year.
I would put more than 3MB of RAM in it though.

I remember upgrading my Apple II+ from 48K to 64K of RAM back in 1983. Now that was a lot of memory to have in a personal computer!

As long as we're reminiscing, I got an Apple IIe back in '84, but it was a replacement for my TRS-80 Model III, which I remember upgrading from 16K to 32K and then all the way up to 48K. The big jump for me was from that 128K IIe to a 2MB Mac II with a 100MB drive in 1988. I don't think I'll ever have a machine so clearly superior to anything else on the market again.

Thanks drive-thru. It's got 3.5 total now, (stock comes with 2 256MB chips). Sometime, after prices come down perhaps, I'll toss those and add 2 1GB chips for a total of 5GB. Of course, when we are really in a 64 bit OS and world, it'll be 8GB for sure! Crazy....Peter

Or 16GB with 2GB sticks

But I thought 8GB was the G5 limit?

8GB is what's officially supported by Apple at this time. Theoretically, the G5 can address up to four terabytes of RAM.

You guys are dating your selves! I too am from that era... Ti99, Atari 400/800, Comodore (commie 64), TRS80 (Trash80), etc...

I got the 80 column card and 16K memory expansion card for my //e, and they cost more than the 3.0 Gig of RAM I got from crucial today (adjusting for inflation)

It wasn't much later that I got a maxed out IBM PC/XT with a whopping 640K and a 10MB hard drive! and COLOR RGB!!!!

Man, we are spoiled with this new stuff, aren't we?
Mac Pro 3.0, ATI 5770 1GB VRAM, 10GB, 2xVelociraptor boot RAID, 4.5TB RAID0 storage, 30" & 20" Apple displays.
2 x Macbook Pro's 17" 3.06 4 GB RAM, 256GB Solid State drives
iMac 17" Core Duo 1GB RAM, & 2 iPhones 8GB, and a Nano in a pear tree!
Apple user since 1981

Apple sells modules up to 1 GB, which gives limits of 4 or 8 GB depending on your G5's slot count. However, the G5 memory controller does support 2 GB modules. Here's the likely reason why Apple doesn't offer 2 GB modules at this time:

1 GB module - $95 (pair for $190)
2 GB module - $335 (pair for $670)
(prices from pricewatch)

Apple's developer notes have mentioned before that 2GB modules are the real max modules recognized. The reference I found just now is here, in the 2nd paragraph.

From the link above...

"Each DIMM can contain 256 and 512 MB (also is capable of 128 MB, 1 GB, and has future expansion ability of 2 GB) of double data rate synchronous dynamic RAM (DDR SDRAM)." (emphasis added.)

Apple does offer 2 GB modules, both on the online store and in the retail stores. A 2 GB memory module is $1200 from Apple.

I think you'll find that they're offering 2 Gb kits that comprise 2 x 1 Gb sticks. At least on the UK Apple store site, anyway.
G5LC, 6 GB 1.07 TB 6800 GT & 30" (Workhorse)
1.4 GHz Cube 512 MB 60 GB (headless folding)
15" 1.67 GHz Ali G4 PB, 1.5 GB 100 GB (VJ rig 1 & Uni)
15" 1 GHz Ali G4 PB, 1.5 GB 60 GB (VJ rig 2)
G4 800 MHz Ti PB, 512 MB 60 GB (Lounge)
