If a system has 3 RAM slots and 2 of them have 2x256MB sticks running in
dual channel mode, is it possible to add a third stick?

Is that an Nforce2 mb? I remember reading about this and I think the
answer was only if the sticks are inserted properly. i.e. your current
sticks in bank 0 and 2 and the 3rd stick in bank 1(or some wierd
combination). But that is just my hazy memory... Some of the guys here
have Ausus Nf2 boards. THey may know.

Not if you want to run it in dual channel mode no

OK, so how do I turn off dual-channel mode? What setting should I look for
in the BIOS?

i can't explain my answer, but i've got a asus a7n8x deluxe (nforce2 board)
and using 3 sticks of 512mb ram. dual-channel/"performance DDR timeing" *is*
enabled.
but dual-channel is way overrated/hype. there's little or no gain.
even if it does stops working after inserting a third stick, the performance
gain from 50% more ram will overshadow any loss of performace from
non dual-channel ddr.

Apparently it performs better with Pentium4 boards. But for AMD, dual
channel's a waste of memory unless you *really* need to squeeze every
last fps from benchmarks.

Yeah, there's roughly a 1% increase in benchmarks from what I've seen. Not
worth losing sleep over. Bit like 8x AGP - purely a marketing gimmick.
Steve, if you're talking about an nForce2 board, I've had such a combination
running for a few days, and it worked fine. The BIOS still showed the mode
as being 'Dual Channel' at startup, so I assume some of the RAM continued to
run Dual Channel mode.
In applications I didn't notice much of a speed difference. Sandra's Memory
benchmark lost ~ 3%.

Yes, the answer is that 2 of the sticks are in dual mode, while the 3rd
is not.

From the ASUS manual...
"To enhance system performance, utilize dual channel feature when
installing additional DIMMs. Install the DIMMs in any of the following
sequence; Socket 1&3, Sockets 2&3 or Sockets 1,2 &3"
I stand corrected
