I just purchased a kbyte 1 gb pc 3200/2700 ddr memory stick. It is an addition to two kingston pc2700 512k (pc 400/333). My motherboard is a abit be7-g. It has three memory slots. It read 1gb when I had the two 512k in the first two slots no problem. When I added the new 1gb in the third slot it would not recognize it. I put it in the first slot and the other two in slots 2 and 3. Now it only reads 1.50 gb. I have swapped the in all known configurations and it will still only read 1.5 . Ny hints?
