In my room I have a spare PC with a graphics card capable of x16 in PCI Express (ATI Radeon X1550 IceQ), so I thought I would test the speed of the video card. After some testing I noticed that it wasn't going the the speed it was supposed to be running at (transfer rate at 700MB/s), this led me to the conclusion that the motherboard is not capable of x16, even though it can take a x16 card.
I have checked the BIOS to see if their is a setting that will allow me to change the speed of PCI Express, which it didn't. I then remebered that I didn't update the BIOS for this motherboard.
So I was wondering; could updating the BIOS allow change in PCI Express speeds?
Note: I don't know much about PCI Express so be nice.
