Need for pairing to adjacent RAM slots went away with SIMMs.
Bank sharing between 2 RAM slots still exists with DIMMs, but doesn't
require that there be RAM in the adjacent slot.
Dual channel functionality is a problem using a a single DIMM, but doesn't
affect by loss of use.

If you want to know if you must always put memory by pair on your
motherboard, simply put back only one of the original memory modules and
see if your computer is able to boot. If not, then you will know that you
cannot add a single memory module at a time; always two.

Hi, purchased ram (corsair 512 3200c2), the systems already has 2/256
3200
400mhz with two extra slots for more memory, I install the memory as
directed, and when I start up windows, it would get to the welcome and
then
it would just reboot. over and over again. I tried trouble shooting by
removing the original memeory completly and replacing it with just the
new
corsair ram and I got the same results. a constant reboot. Did I get bunk
memory, or is the ram I purchased incorrect? Can anyone help?
The corsair memory is on one module, unlike the original, which is in
two.
Does this make a diffrence?
I thought windows would just recognize the new memory automaticly, or is
there something I missed?
