Code:
PCI-E 1x Link Width issue :

Happens when OC-ed. After restart link width is automaticlly set to 1x instead of 16x, which causes significant performace downgrade.  Reason unknown. Happens mostly with ATI GPU cards. Possibly a BIOS protection measure, preventing percieved possible damage to GPU or motherboard, or a BIOS problem with proper video card  initaition.

 

Symptoms :  

PCI-E Link Width switches from 16x to 1x after a restart.

 

Solution : 

- Unplug PSU, wait a few seconds, replug PSU.

- Unplug PSU, reset CMOS, replug PSU, renter all BIOS settings, save, shutdown, power on.

- Combining slightly lowering or uping voltages of PCI-E, Vmch, VCore and FSB can usually fix it. Also try

  disabling ASUS C.G.I and PEG Force 1x., and changing values to PEG Link Mode.

- Flash to BIOS to previous BIOS version, then reflash to current.
If this doesnt work either RMA the board.
Hope it helps...
