Im currently building another cheap pc for quake etc by buying 2nd hand parts or cheap from ebay.

Ive seen some triple channel ddr3 ram (3x2gb) that seems to go for the same price or cheaper as dual channel (2x2gb) ram. The motherboard will have 2 ram slots, my question is if i buy a triple channel kit and just use 2 sticks and sell the third on will the 2 sticks just work as normal in dual channel?
