I have a pcie clock set to 100mhz in my bios - will changing it give me some advantages in my video card performance???

Thanks

If u want ur comp to crash sure go ahead :p

This is the clock speed of the interface, not only can it make ur comp unstable, but it wil also make no difference what so ever. The PCIE interface is MORE than enough, considering cards only now are starting to be restricted by agp4*.

What's your motherboard?

On older boards with no pci-e lock I found 108mhz set manually will allow ~250fsb overclock.

Messing around with your pcie clock will most likely destabilize your system. Not a good idea.

depends on your mobo, imho

on my MSI K8N Neo4-F, I got best stabilty/ somewhat higher 3DMarks at 110mhz

on the VNF4-Ultra, it didn't have any positive effect on performance, but didn't hurt stability, so I left it @100mhz

on my DFI, even 103mhz results in instablity for me

I've heard a couple of times that changing it can enhance stability in some instances using an Nvidia chipset board with an ATI GPU, in the order of just a couple of MHz (like 105MHz or so). Dunno if that's just a computing urban legend or not.
