Dual Channel Mode?

I need to identical sticks of memory to run dual channel, Right? If I fill
all 3 slots on my mobo. I cant run dual channel, is this correct? So if I go
1 Gig now and add some more later my dual channel setup wont be in effect.
Enlighten me, please!

Rick

Dual channel mode with 2 sticks= 1 in slot 1, 1 in slot 3.
Dual = 1 in 2, 1 in 3

Slots 1 & 2 = Channel 1
Slot 3 = Channel 2

Therefore if you put 256Mb sticks in Slots 1 & 2 and 512Mb in Slot 3, you
will be running in Dual Channel mode. It is better if the sticks are
identical, but I am running a mixture of PC3200 and PC4000 in my machine in
DC mode.

This is for the K8N-E, a socket 754 board. It is single channel only.

Socket 754 is 64 bit (single channel), while socket 939 has room
for 128 bit mode (dual channel). As per the summary sheet here:

http://www.amd.com/us-en/assets/cont...docs/24659.PDF

The only population rules to follow, will be any table in the manual.
Check carefully, to see how many DDR400 sticks it will support.

Since I cannot find a downloadable manual for the board, the paper
copy in the motherboard box is the only reference material available.

True.

well most replys were wrong...

slots 1 and 2 are channel 1 and slot 3 is channel 2
to attain dual channel with 2 sticks, use slot 1 and 3, or 2 and 3
to attain dual channel with three sticks place 2 equal size sticks in
slot 1 and 3
and the third stick of an equal or greater size in slot 2

the ram does not need to be the same size make or speed on an nforce2
chipset board.

forinstance you can have 3x256 in slots 1 2 3, or 2x256 in slot 1 and 3
and a 512 in slot 2, this would be ideal where channel 1 equals the
amount of ram in channel 2. but this is not a requirement of dual channel
mode.

So what do you do if you had a 1G stick and 2x512?
Place the 2x512 in slots 1 and 2 and the 1G stick in slot 3? or the 512's
in slots 1 and 3 with the 1G in 2?
I understand the second choice to be correct, as when 3 sticks are used 1
and 3 indicate dual channel mode and slot 2 is split between the two
channels.

Hopefully your adequately confused now

So as you can see there are many variables, each neededing a certain
configuration.

May I ask a supplemental question?

My BIOS (P4C800D) says "dual channel linear mode"

What _is_ linear mode, and is it optimal?

See the Intel memory guide. It is the best we have to offer.
