I just got done looking up my current RAM and found out that NO it does not work with nForce2 chipsets at all and does not support dual channel in some motherboards. I ordered a pair of Corsair XMS 2x512MB RAM from ZipZoomfly and it should be here early next week.
Basically, what I found out is that the RAM I ordered is specifically for nForce2 chipsets and running dual channel. I guess I am set. Currently I just put back the 2100+ chip in the computer to keep it running till I am ready with the new RAM.
Thanks for the help all,
Michael
