Hello everbody! I´m a owner of a Logitech Formula Force steeringwheel. The steeringwheel works much better on the serial port than the USB port. Using the steeringwheel on the USB port causes problems as the computer not fully respond of my commands. The serial port works much better. Are where some known issues with the USB port on P3V4X. (However except that my mobo works very nice. A month ago I buyed a Inn3D Gf2 PRO, an belive it or not, the Gf2 PRO works very stable (4X AGP) from the beginning. I have not tweaking so much, and have not yet have use for to change the undocumeneted jumper next to the CPU fan connector to increase from 3,3(3,46) to 3,6 volt) Except the parenthesis I am very thankful for answer. Have a nice day.
