So if i use 2GB x 2 ram, will dual channel work? or will it not work because Window XP 32-bit can only detect 3.25GB?
Yes, dual channel mode will work.
how do u set the dual channel in the BIOS, someone please teach me =(
You don't set dual channel in the BIOS. Dual channel is achieved by inserting matching memory modules in the proper DIMM slots. RTFM!
