Hello, I have an optiplex gx280 (yes i know, sort of old haha) with what I believe to be the Intel 915G Chipset. Everywhere on the official specs, the maximum Ram is only 4 gb, however, sporadically I'll find threads saying that with 64-bit this chipset can actually accomodate 8gb (2gb per slot). I have the desktop version. Before I go off and buy either 4 x 1 gb of ram or 4 x 2 gb or ram, is the 8gb compatible? Thanks.
