In slots 00 and 01, 1GB each of DDR2 SDRAM at speed PC2-4200U-444
In slots 02 and 03, 2GB each of DDR2 SDRAM at speed PC2-3200U-288
In slots 04 and 05, 1GB each of DDR2 SDRAM at speed PC2-4200U-444
Slots 06 and 07 are empty
Everything in AE and FCP creeping along at a snail's pace. Is it just the wrong RAM?
Dual 2 Ghz PPC G5, 8 GB DDR2 SDRAM
I'm not familiar with the numbering you're using, but Pairing is the most important, 1 with 1, 2 with 2, etc...
4-3-2-1*1-2-3-4
Next in importance is bigger ones in the inner slots, next is all matching RAM.
When it's slow, open Activity Monitor in Applications Utilities, choose show all Processes, sort on CPU%... what do we get for numbers?
Ten click on the Memory tab... are we getting lots of Page Outs?
How much Free Sace is on the Hard Drive?
Your Dual-Core 2.0 GHz G5 tower uses PC2-4200 (DDR2-533), not the slower PC2-3200 (DDR2-400). Remove those (2) DIMMs and the problem should be eliminated.

I think you're on to something there. Who knows how much the memory controller slows down for the 3200 chips. I bet farther than down to 400 MHz.
You may very well be right, but I think I've seen some RAM just reported that way but still worked fine.
I don't know which numbers in the CPU % would be significant or how to read them. Threads: 433, Processes, 79. % User, is going between the high 3 to the mid 10 range. Percent idle is up around 80-something now that i'm online here rather than active in AE, for example. If I just hit play in AE, rather than trying to do any work in it, the percent idle goes down to the 30s and 40s....The page outs number is 152KB. What does that mean?
Page Outs mean it ran out of RAM for something & had to use the HD, but 152KB isn't too bad.
Did you try removing those PC3200 sticks as suggested?
On CPU%, it doesn't appear to be that so far.
Just picked up an A1117 (G5 2.0 DC). My questions are:
1. How can tell if ECC memory is required or not?
2. Can I go with a higher speed RAM (PC5300) since the RAM will down-clock to accommodate the slower speed?
3. Is install in pair a requirement or is just to support performance boost from interleaving?
Thanks!

Install in pair is a requirement; the machine only recognizes pairs.
You can download the appropriate manual for your machine from this Apple page and get the exact specs that Apple recommended.
1. How can tell if ECC memory is required or not?
It is not required. It is supported in the dual core G5's, but is not mandatory.
If used, all RAM installed should be either ECC or not.
2. Can I go with a higher speed RAM (PC5300) since the RAM will down-clock to accommodate the slower speed?
Yes you may. Expect misreporting of the RAM, however.
Most faster RAM will report as PC2-3200 in OS X.
3. Is install in pair a requirement or is just to support performance boost from interleaving?
It is a requirement of the architecture.
Any suggestions for a PCI-E based wireless card? Not sure I want to go the route of adding the Apple one (looks like a giant pain). Thoughts? Thanks!

I'm not aware of any that are PPC/OSX compatible.
USB adapters are plentiful.

I don't know about a giant pain. Delicate, yes, but not so hard:
is this strictly speaking mismatched RAM?
