Solution to the PCI-Express X1 bug Part1

Solution to the PCI-Express X1 bug:

The reason on why I wrote this article, is simply because I have seen many whom had their board's PCI-Express bus width stuck at X1 while overclocking (especially the Asus P5B series). So today, we are going to find out what will work and what won't, as well as it's impact on gaming & HD content.





Motherboards that might be affected:
-Asus P5B vanilla
-Asus P5B-E Plus
-Asus P5B Deluxe/Wifi

-Gigabyte P35-DS3L
-GigaByte P31-S3G




Graphics Cards that might be affected:
-Radeon X1950Pro
-Radeon X1950XT
-Nvidia 8800GT


How to check if you are affected:

Download CPU-Z or GPU-Z



if your PCI-E bus is running at x1, you are affected by the bug,




else if its running at x16, then you are not affected by the bug.



Rumored solutions that doesn't work:
-Setting the PCIE Bus Frequency to 96Mhz
-Setting the PCIE Bus Frequency to 101Mhz
-PCI Synchronization Mode to 33.33 MHz
