Motherboard info



The wife's desktop has a 1.3 GHz AMD Duron processor on an unknown
motherboard, that came with 128*1 MB RAM. I've upgraded it to 512*2 =
1 GB RAM. The m/b has only two slots for accepting RAM. Today, I
noticed this:

The info looks like I've got four RAM slots, with a max capacity of
128 MB for each, giving a total of 512 MB. However, looking at the
m/b, there are clearly only two slots. Is 768 MB (1024 - 2*128) of RAM
going to waste? It also lists 5 PCI slots, although the m/b clearly
has only two. Googling the motherboard product name leads me to
believe that what I'm seeing in the case is the right m/b, and that
the info in dmidecode is incorrect.

So, is the system using 1024 MB of RAM, or only 256? It is dead slow,
and I easily outtype it (I wait to see my letters appear on the
screen). All software is _slow_, especially digikam which we use a
lot. Note that mplayer video and mp3 files in Amarok play fine.
