yes you can increase the pci-e frequency but you wont see any improvement just instability and the risk that you will fry your card if you go too far

It should be as simple as changing the PCI-E speed in your BIOS; shouldn't be far fromw here you adjust FSB.

However, upping the PCI-E bus speed is usually pointless, even if it is a limiting factor (it may be with crossfire), if you up it to the point you can measure a performance difference you'll like have made your system very unstable.

Intel chipsets do not respond well to increased PCI-E speeds.
