I have a G5 2.0 Rev b powermac. I currently have 1.5 gig and because of photoshop and aperture I want to boost it. I see crucial has a 2 gig kit for $238 so I may jump on this.

While the PM can take in a gazilion amounts of ram, is there any limit for the apps, I thought some applications could only see something like 2 gig. I forget what the threshold is (or even if the threshold exists). I don't want to get memory that will have a limited benefit to my need.

Thanks in advance.

Mike,

I have a G5 Dual 2.0 with the following specs:

Machine Name: Power Mac G5
Machine Model: PowerMac7,2
CPU Type: PowerPC 970 (2.2)
Number Of CPUs: 2
CPU Speed: 2 GHz
L2 Cache (per CPU): 512 KB
Memory: 4 GB
Bus Speed: 1 GHz

I find Aperture and Photoshop CS2, can use as much memory as you can throw at them, especially if you switch back and forth , like I do. I don't know what the address limits of thes two apps are.
I use PS to work on RAW images, and also slide scans. Real memory disappears pretty quickly in this scenario.

I think PSs memory cap is somewhere around 2 GB, so you've got plenty of room for expansion.

If Apps do have a cap it will be around 2Gb (this was the old limit on the G4). But in practice the OS takes up a lot of RAM, and any other apps that are running, so it would be at least 2.5 to 3Gb of RAM being used.

But I doubt that this problem exists. At least not any more. Most serious apps have G5 versions now, so they would have addressed the memory issue.

Upgrade away, my friend.
