Motherboard gigabyte 81845 has 2 physical dim m slots 512mb x2 ram is installed. larger size (1gb or more)S DRAM unavailable to purchase. Some program failed to install as it needs 2gb ram. I have extra ram sticks, but how to accommodate is an issue. One side of ram stick is empty. If I could add chips that side what will be the result. If somebody find this test useful then comment on this thread.
