I want to upgrade my memory on a iMac G5 17" powerpc64 but how do I find out what memory cards are used? I should find this info in a system description but where in Ubuntu?

Hi

I think that this command will show you what you need (and probably more). Open a terminal (Applications->Accessories->Terminal) and enter the command below. The computer will ask for your password, type it in and press enter even you won't see anything while typing the password, it is ok.

sudo lshw -C memory

Scroll backward through the output until you see a line beginning with

 *-memory

The lines under this will describe your system memory.

 Lines that begin like the below (maybe with different numbers) are describing your controllers

 *-memory:0

Hope this helps

I would not expect this information to be available in any standard application like gnome-system-monitor. This kind of information should be handled by the BIOS.
I don't know Macs but couldn't that information be found in the BIOS setup? Or during boot-up?

Any OS, including Ubuntu would be glad not having to worry about these details.

On the other hand: Shouldn't Apple be able to tell you what kind of memory you need? And if you then buy a current (fast) version of that type, the speed of the others won't matter, it should still all work together.

sudo dmidecode

This allows you to dump a computer's SMBIOS table of contents into a human readable format. This table contains a description of your hardware components.

Disregard last message, it seems that dmidecode does not work on powerpc

Kingston memory technology has a detailed list of memory modules which can be looked-up by machine name, etc. Problem solved.
