Need to upgrade memory in ppc mac mini

Question

Does anyone know of a step by step guide with pictures to installing memory in a ppc mac mini? Need to upgrade to a gig to use some graphics software. Thanks,
Steve

Answer 1

In sleep mode (STR) the RAM has to be refreshed to
keep the memory content, so the more you got the more
power will be consumed on this.
Having less ram will therefore benefit battery life
in sleep mode.
This is only of concern to portable users of course, and the additional RAM has barely any impact on power demand whether from mains-power or battery. Some admittedly, but not much. Nor would it be all that easy to tell what drain it caused since there are other variables involved with battery drain rates too, such as ambient temperature.
There is still room for improvement in whatever
algorithm it is that determines when "inactive"
memory is released. Paging frequently happens after
copying large files since all memory is in use and
"recently" so, even if this use is one where the
content is NOT likely to be needed again.
The much hyped idea that "old" inactive memory is
being released when more is needed I find it
difficult to confirm, or paging would not be needed.
Simply caching EVERYTHING does not in my mind count
as an "intelligent" algorithm..
As much as this may be valid, there is no way the user is able to change the algorithm - it's part of the operating system. As such, the user can really only take such steps as may be possible to improve the working of the system - one significant such step being adding RAM.
This can be cleared up by running "repair
permissions" in DU, since it seems to release much of
the inactive RAM. It would be much better to have a
small utility to do this, though, if making the OS
more intelligent is not an option.
Running disk utility may be an effective method of resolving memory allocations etc, but it then places the onus on the user to monitor the system and manually activate a process. Part of the appeal of MacOS to many people is that it removes much of the onus users of other operating systems feel is placed on them to keep tuning the system - activities which detract from the use of the system.
Ultimately, I have to say that I have never found the need to do anything of that sort. I do use MenuMeters (a very neat little app to place system monitoring tools in the menu bar and which uses barely any CPU overhead to do so) to watch the status of my system, but only as an occasional troubleshooting aid when I'm testing software or experimenting with the system. That is about as far as I go with anything other than using the system. Certainly, I've not found any need to perform the sort of tasks that are often being recommended, and even the systems I run 24/7 remain efficient in operation.
I can say that while my G4 was running off a 5400rpm drive, increasing RAM from 768Mb to 1.5Gb quite dramatically improved performance of both 10.4 and 10.2 but had little benefit in OS9 (all booting from separate drives). The effects were rather less noticeable after swapping out to 7200 drives instead.
