I have had 256 mb of pc 2700 (Corsair) in my albatron kx600 motherboard. It has been working great but i opted for more ram. I had an extra stick of pc 2700 (kingston) lying around so I popped it in the motherboard. Unfortunately, windows still shows only 256 mb of ram. I tested the sticks individually and they both work, but together it only registers as 256!?!?!?! ANy suggestions?
