Dual Channel Ram Questions

I am running 2 sticks of 512 3200 ram in dual channel. If I switch both
sticks to the same side of my mobo, and install a one gig stick on the
other. Will it still run in dual channel if both sides are matched? Also,
if I install a stick with multiple speeds (3200/2700) will it run dual
channel?

no, if your board is like mine you must put the ddr in slots 1 and 3
then 2 and4 it will run but probably as single channel memory
not know what board you have I am only guessing

My old ram in 1 and 2, the gig stick on 3.

No, as the way you described it.

Should be identical.

No, and No. However, if you need more RAM, then don't worry about the dual
channel. It doesn't make that much of a difference anyway. In other words,
2 Gig of single channel RAM will be significantly better than 1 Gig of dual
channel. -Dave

That was another question that I had. Thanks for clearing it up.

I would think this would be the case only if he is using more than 1gb of
RAM, which seems doubtful unless he's running some memory-hungry progs. I
do photo editing here with 1gb RAM and rarely use more than 1gb. The only
time I've seen it use more is running Nikon Capture Transfer or loading 50
or more digital images in PhotoShop.

If he is not using up the 1gb of RAM, he's better off with 1gb of
dual-channel over more RAM in single-channel mode, IMO.

I measured ram usage on my box and tops was maybe
800 meg. I had several programs and games that gave
figures like 650 meg, but still they seemed to be going
to disk too much. Finally I upped to 2 gig, and the disk
problem cleared right up. Games and programs ran
much cleaner ?????? Only thing I can figure is stacks
don't take up ram until they grow ... but the area of each
stack is still reserved, so nothing can use it, and that
greatly reduces available ram for programs. 2 gig
cleaned it up. I run PhotoShop, and even plot out of
it ... not smart, but works. Typical high-rez plot size
is 800 meg. Works much better now.

Wow...it must be different in the DDR2 world as my Intel mobo will do
just that (D915GEV).
