This might be a dumb question, but I'm not sure with the Mac motherboards...

If I buy a single-processor G5 (1.8) now, can I add a second 1.8 G5 to make it a dual?

Coming from the PC world - some dual processor boards can operate with either one or two processors, so you can buy one and upgrade later.

Is this true with the G5?

Thanks in advance!

You definitely can not. Get the dual - they are sooooo much cooler (because they have more fans...duh)

If you're curious, the mainboard is essentially the same on the two higher-end G5 models, but the connectors to attach a second CPU are removed on the 1.8 GHz system's mainboard.

Yeah, keep in mind if you skimp on stuff like the optical drive you can really drive down the price of the upgrade.

The g5 motherboards all have 2 CPU sockets, including the 1.6 if I'm correct, but the 1.6 motherboard, unlike the 1.8, has regular PCI and only 4 ram sockets (2 on the top, 2 on bottom).

While YOU cannot add a socket to the 2nd port it might be possible in a year or two for a company like sonnet or powerlogix to make a mail-in package where you send it in to their soldering company and they install a second socket for you <-- problem is this is very hard to do.

So it's unlikely you'd make that single a dual. On the other hand, however, you can make a dual CPU g5 a single one later on or upgrade the CPUs on either.

wait a minute u just said they came with two sockets then you said yuo couldn't add a second socket that doesn't make sense, if they come with 2 sockets, why'd you need to put in a second one?

Well, I think he meant that the pin holes are there but the actual cconnectors for the CPU to plug in to are not slodered on.
Hope this helps.
