Dual Channel or more memory?

I've got 1024Mb memory with 2 matching 512Mb PC3200 running in dual
channel mode. Is it better if I fit another 512Mb PC3200 chip for a total
of 1536Mb memory or should I just leave well enough alone?

Overall system performance.

Of course more memory increases performance. :-s

There seems to be a question about that when it comes to the dual channel
architecture. Supposedly dual channel mode doubles the throughput of the
memory so that means my 1Gig of memory will actually act as 2Gig's.
Introducing a third 512Mb memory chip, even if identical, drops the system
back to single channel mode giving me only a Gig and a half. In theory
that extra memory would actually slow my system down.

Is your motherboard configured for the use of dual channel?

Yes and the BIOS does report dual channel mode is active on boot up. It
has only three slots however, so I can't use four chips and still get dual
channel mode. I can only put one chip in slot 1 and one in slot 3 for it
to work. Fitting the third chip drops me back into single channel mode.
