DDR2 RAM in dual channel mode....

my mobo is MSI K9N NEO F. i have 2*512MB DDR2 @ 667Mhz. how will i arrange it to run in dual channel mode??? HELP

also...CPU-Z latest version shows my ram is always in slot 1 when i put 1 of my ram in any slot. there are 4 slots in my board. and when i insert the 2 ram, it also show that it is inserted at slot 1 and 2 even when i inserted at 3 and 4. BIOS is latest version......................

put both the RAMs in DIMM 1 and DIMM2. u can know the dimm 1 and 2 slots by looking at the manual of the mbd.

you have 4 DIMM slots..
consider like this
DIMM 1 & DIMM 2 as A
DIMM 3 & DIMM 4 as B
now to use dual channel config.. you must use one ram in DIMM 1 and the other in DIMM 3 (i.e one is A and other in B, but you should use either 1 & 3 or 2 & 4 combination)
also configure you bios for dual chan config

hhhmmmm....... DIMM 1 and DIMM 2 OR DIMM 1 and DIMM 3???

DIMM 1 and DIMM 3 is the right choice

the slots are color coded , go for 2 similar colored DIMMs

sometimes all the slots r of same color. also dimm1 n dimm2 may not b adjacent. that is why i told u to read the motherboard manual. here... this link might help...

dual channel works only if you put your RAM on
DIMM 1 & DIMM 3 or
DIMM 2 & DIMM 4
if you put in DIMM 1 & DIMM 2 (or DIMM 3 & DIMM 4)it works only in single channel config..

Look inside the mobo manual .. dduuh ... !!!

Colour codes obviously. Just check which is DIMM1. Unless MSI thought they can do with some colour games(I saw a MSI with wrong colour coding).

ok.....i got it
