I've been searching for some hours now with no answer. I built a system (Win 7 32bit) with a a Striker II Formula and I am noticing that it cannot connect to my network with 1Gbit but only 100Mbit. I tried forcing it, but there is no option available. When checking the mobo manual, I saw that on a table, it had some figures that said: 32bit OS: the LED will be orange when the link is 100Mbit. It didn't say anything about 1Gbit. And on a table below, it said 64bit OS: LED will be green when the link speed is 1Gbit. Is it possible, that the 780i needs 64bit OS to have 1Gbit speed? It seems odd. Thanks.
