When you overclock your Pci-e clock to lets say 105 MHz,  would you see any performance increase?.
I have a 8800 Gtx,  so i reckon it likes the extra bit of bandwidth.
I don't want to fry my card,  but i couldn't care less if the MB explodes.
The rest of that system is maxed out right now,   but there's still that 1 option i didn't touch.
I do know the range for this thing is:  100/145 MHz,   so there's some room to play with :p.
And its a PCI-e clock only,   not PCI / PCI-e clock.
Should i give it a shot, and run some benchmarks right after that?,  just to see if it actually did something.
Btw. this is still on my (old) 939 rig, with now a msi MB,  as my asus board died on me 2 days ago,   and the worst thing is i already sold the parts, so i bought a new MB, just to give it away

It will become unstable, so don't bother. You have an 8800...why would you need MORE?! lol

I have heard that raising the PCI-e clock to 104MHz can help with overall overclocking stability(CPU, RAM) in some circumstances, but doesn't increase video performance. Anything over 104 and you're risking causing problems for yourself.

you want to DECREASE it to put less pressure on the motherboard and components etc.

The only time you want to lower the PCI-e frequency is when the board has no PCI-e lock. Otherwise the PCI-e frequency rises as you raise the CPU FSB, possibly too high.

But as I said, in some situations people have reported raising it a few MHz can help stability when overclocking CPU & RAM:
