I have a G5 Dual Core (2.0) (Late 2005, M9590LL/A, PowerMac 11,2) that has
eight memory slots. EveryMac says that this G-5 is maxed out at 16 GB of
memory. Mine has 8 GB right now (1 GB chip in each slot).
Does that mean that if you put more than 16 GB in the memory slots, it will
only recognize or use 16? I heard that you can sometimes put more memory in
some G5s than Apple claimed was the limit. Is this G5 one of those?
Say I were to put 4 GB chips in four of the slots, I'd get 16 GB of RAM
from those, and there would still be four slots with 1 GB in them. Would
this Mac then recognize 20 GB of RAM, or only 16?
For that matter, what if I filled every one of those eight slots with 4 GB
chips--would the Mac then recognize and use 32 GB?
I'm doing Final Cut video editing with this Mac, and the render times are
awfully slow. I sit for long periods just waiting for the render bars to
fill up, and nothing can be done until they do--the program is frozen. I
could sure get a lot more done if i could speed up that rendering, and some
people tell me that maxing out the RAM helps a lot.
Any advice appreciated.

4GB DDR sticks do not exist. Sorry to bust your bubble :/ Even 2GB sticks
are hard to find and expensive; so expensive that it is probably more cost
effective to just buy a new mac.

2 GB sticks were the largest which were made (or are presently in stock of
PC2-4200 RAM).
2 GB * 8 slots = 16 GB, which matches Apple's spec.

I bought a similar G5 from a video producer. He was hurting for
faster render times and moved up to an 8-core intel Mac Pro,
My audio needs for this machine are perfectly well-met. I don;t know
the comparison data specifics, but your render times may well be what
teh machine is capable of. My audio needs for this machine are
perfectly well-met

Here is the link to the OWC webpage that sells 4 GB RAM chips for my G5:
<http://tinyurl.com/bnqxdyt>
The price ranges from $61 to $73 per chip.( I don't know why some RAM chips
cost more than others--can someone enlighten me?) 1 and 2 GB chips are also
offered there.
At $61 per chip, I could put 16 GB of RAM into this G5 for $244 + shipping.
If I left the 1 GB chips in the remaining four slots, would the Mac
recognize and use 20 MB?

You're reading this WRONG, there's no such thing as 4 GB modules, this
is for TWO 2 GB modules, a MATCHED PAIR (2 x 2GB = 4GB).

Price is cheaper now, I see $57 per pair, but still, you need even
cheaper prices.

Again, the 16GB represents EIGHT modules that fill all the slots,
there's no place left for anything extra. The maximum RAM is EIGHT 2GB
modules (8 x 2GB = 16GB total). That's it. At $60 per pair, this is an
iffy economic proposition. These G5 are right on the cusp now, and any
investment is questionable in comparison to newer models with cheaper
RAM.

Indeed so.
Manufacturers now specify the TOTAL amount of RAM contained in a RETAIL
package.
Example: a two stick package may be stated to be 4 GB, and the RAM will
indeed be marked 4 GB, but it will also state 2 x 2 GB.
Another example: a three stick package (for, say, an X79 system) may be
stated to be 6 GB, and the RAM will indeed be marked 6 GB, but it will
also state 3 x 2 GB.
I have quite a few so-called "6 GB sticks".
The precise language printed on EACH stick in a set of sticks is:
1333 MHz 6 GB (3 x 2 GB) 9-9-9-24 1.50 V ver 2.12

Ah, 2 X 2 chips = 4 GB. Should have looked closer. Thanks Kris and Peter.
So 16 GB of RAM maxes out this G5.
Still, that would double what I have, and if i were sure that the rendering
times for Final Cut 5 would be significantly reduces, I'd go for it.
I just got a Mac Pro and Adobe CS6, but I have some long-term video
projects going on the G5 with Final Cut 5, so I will be on the G5 for the
foreseeable future. After years of experience, I know how to do exactly
what I want to do in FCP
5 and do it quickly. The only thing slowing me down is those agonizingly
slow render times. They stop me dead every few minutes.
The Adobe CS6 software I just bought for the Mac Pro includes their video
editing program, Premiere Pro, but Premiere has a learning curve that I'm
just now getting into. Plus, it seems to lack a lot of the features I'm
used to in Final Cut, for example the number of video transitions it offers
is pitiful. Final Cut, for example, has fourteen slide transitions to
Premiere's one, and that's typical. And there doesn't seem to be any
equivalent of Final Cut's Soundtrack, LiveType, etc. Adobe has After
Effects but I'm not sure what it can do, yet.
My new Mac Pro, Intel-based, cannot run my Final Cut 5 program in OS 10.8.
In fact it can't run any version of Final Cut Pro, even Final Cut 7. Apple
abandoned its longtime professional video editor bas when it dumped Final
Cut 7 in favor of an entirely new and different program they call Final Cut
Pro X. Nothing but the name is similar. All the helper programs for Final
Cut that I'm used to--Soundtrack, LiveType, Motion, etc. are gone. As I see
it, Apple dumped the pro editing community in favor of the far larger
market of teenage boys wanting to make skateboard and snowboard videos for
their friends with mobile devices. Apple goes where the money is, customer
loyalty be damned. They did the same thing with iMovie sometime back.
So until I learn a new editing program (NOT FCP-X, which is not
track-based) I'll continue to do video editing on what I know, FCP 5 on my
G5. It was while sitting through one of those long renders, with FCP 5
frozen in the meanwhile, that I began wishing for a way to speed things up.
Doubling the RAM in this G5 might, or it might not. I'm still considering
maxing out the RAM.
Thanks all for the help.
Tom

Likely not. Video rendering is heavily heavily CPU bound.
Here's a suggestion...install Menu Meters: <http://www.ragingmenace.com/software/menumeters/>
And see what's going on.
If the free memory dwindles to nothing, and the CPU isn't pegged, the bottleneck is RAM, and increasing it will help. I'd be willing to bet, however, that the CPU meters get pegged at max and stay there.

Besides what other people have mentioned about the *actual* DIMM sizes,
if you are using a 32-bit application -- and I don't know of a 64-bit Final
Cut for PPC, though I could be wrong -- the maximum addressing range of that
app regardless of your actual RAM is 4GB.
That said, OS X can map multiple 4GB ranges to multiple apps, so if you
are running large numbers of simultaneous apps, then you might benefit from
the extra RAM (but you'd benefit more by not running lots of simultaneous
apps during time-critical operations ;).
Also remember that the 4GB is a *range*, not an allocation; OS X only maps
pages as they are actually used. So, as Clark said, I suspect your real
problem is the CPU. The dual 2.0 was not an especially fast G5 even at the
time and certainly not compared to the later models.

Also something you need to take into consideration is that the G5
architecture requires you to increase you RAM modules in pairs. Meaning, if
the DIMM 1 Slot 1 (front slot) has a 2GB stick in it then the DIMM 2 Slot 2
(back slot) must also have a 2GB stick in it or the system might not
recognize the 2GB in Slot 1 or it might give and error beep or tone and
refuse to boot altogether. Same with all the other pair of slots. (front
and back each being a pair)
This was a very common mistake I have seen so many do and not understand
why their configuration wasn't working.

Regardless of price, you definitely aren't going to see much improvement. Speaking from experience, with video work you'll see the most gains in processing, storage speed, then memory.
My current gen base model MacBook Air will run FCPx just fine and without too much drama. Obviously with full 1080p it's a bit slow but it works. It would likely be a huge step up from your G5. And my late-2011 15in MacBook Pro absolutely tears through anything I throw at it.
Do yourself a favor and look into a newer Mac. Even a core2duo Mac mini would be a big step up.
