iMac Upgrade Success and the case of the Mystery DIMM

[macosten]

I successfully upgraded my iMac G3/350 to an iMac G3/600. It used to have 9.2.1 on a 6 GB HDD. Now, it's Jaguar with 9.2.(2?) for classic. The supplies (mobo, mystery DIMM which I will need help identifying later, HDD) had been given to me by someone who had a Tray Loading "Life Savers" /333 mHz model, and the upgrades wouldn't work with his model (plus he only had 32 MB of RAM, while we all know OS X demands a minimum of 64 while liking at least 128 to run).

I had several reasons to upgrade. First, the CD drive is broken (replaced with an external USB DVD drive atm). Secondly, only one of the two USB ports worked. Third, FireWire.

It feels SO EMPOWERING to have done this!

Strangenesses include the fact that the power LED is always amber, not green, but I'm disregarding that for now.

I'll get a picture of the mystery DIMM up so you can see what it looks like. I think it's VRAM bit I have no clue. One of you vets should be able to figure it out

How much RAM? If you'd like more, let me know.

640 MB of system RAM. The Mystery DIMM is a 4 MB... thingy.

VRAM?

That's what I was thinking, but don't these things have about 16 MB VRAM (MacTracker says 8 or 16 MB)? Isn't the VRAM soldered to the board as well? I don't see why 4 MB DIMM will help with anything... Unless I'm missing something.

Well, the tray-loaders have an SGRAM slot so I figured maybe your guy hooked you up with a 4MB module for it.
