I've read on here that a 8X AGP card will fit into a 4X slot, But i have also read that as the voltage are different, that putting a 8X which i think is 0.8 into a 4X, which i think is 1.5v or something, can damage the whole system. Does anyone know for sure? The board is a couple years old (MS-6382E) And I am upgrading it for someone. It currently has a Geforce4 MX420 64MB. I can't find anything about this board, so does anyone know if this will work adding a 8X? Thanks.
