So I get myself a 3200+ and then buy two separate sticks (same company,
style, type, etc.) of PC3200 RAM at 512MB each. I put them in slots 1 & 3
so I can run in "dual channel." As things happen this does not work...the
OS will not come up after the BIOS boot screens and memory test (memory
tests fine). Anyway, I check the manufactures web site and it says that it
is important to have two of the exact same RAM sticks or you will have
trouble. Okay, so I return the sticks and get a "dual channel kit." This
works fine and I have 1 GB of RAM - 512 in slots 1 & 3. Everythig is
working now. But...

Here's the question: If I have to have "matching" sticks of RAM for dual
channel to work...what if I want to stick a third stick in slot 2? This
will obviously not be part of a "kit" and most likely not match the other
two sticks. How does this work????
 
you dont need matching sticks....i have 2 different pc3200 ram chips and
they work in dual channel 2x512, on same board
 
I have done so but I also have OCZ Ram and not any generic..some say to add
a 3rd you should then add a 1 gig stick to balance out your 2 512s..I had 2
sticks 256 PC3200 and all I added was another 256..dual channel does not add
that much performance so I would not worry about it

You know,, the funniest thing happened to me a month ago when I
upgraded... I was going to get an Asus A7N8AX board and use Dual Data
Channel but the shop didn't have any left in stock... The guy there
said that board didn't support DDC anyway... Strange..!!! I could
have sworn I saw it "did"... And besides,, my younger brother has one
and he says it works on his....
Anyway, I was looking for an excuse to move away from Asus stuff as
they are beconing very average nowadays, so I bought a Gigabyte board
and have DDC now up and running...

Personaly, I beleive the most common way to fix this issue on the A7N8X
is to raise the Voltage on the RAM. I find 2.7V makes my two sticks of
Corsair XMS-3500 512M stable. They have never worked at 2.6V on this
Version 2 board, or with my prior Version 1.02 A7N8X-Deluxe Motherboard.

You don't need a Duel Channel Kit, it's just Marketings way of saying
they work in Duel Channel and I would presume they also Guarantee them
to work with a Stock Voltage setting. I wouldn't be surprised if they
tell you to raise the RAM Voltage to 2.7V in one of those kits.

From memory the two coloured RAM slots 2 & 3 worked here and slots 1
and 3 didn't.

Hope that helps.

I have A7N8N and I've had many problems matching memory
for that board. For a month I didn't succeed to make my system stable.
It's very fastidious MOBO.
