I ran lshw yesterday while looking for what kind of memory I have, so I
already have the motherboard info:
MSI MS-6380E

Could be.

I remember putting one of them in myself several years ago when
upgrading to a whole gig was a big deal.
According to the CNET review, the motherboard supports 333 MHz, 200 MHz,
and 266 MHz. I figure that once I know what the installed ones are I'll
get another that is the same speed.

Economy is required. Hence, I'm trying to keep what I have and just add
another gig.

That would be useful to know since performance is something I'm trying
to improve.

I assumed there would be some gotcha if they were mixed. I thought they
might not work together at all.

If I don't come up with another solution I'll try that before pulling
the cover off the case.

As mentioned above, I've tried that.

Now that you mention it, I think I still have the motherboard box, and
the docs. I'll have to dig those out.

See above.
Thanks for all the ideas. I'll do some more digging and see what I find.
