Default PCI-E bus overclocking

Will overclocking my PCI-E 16x bus help my over-the-hill X850xt PE ?

How high can I overclock my PCI-E safely?
Can overclocking the PCI-E hurt systems stability?

My chipset is NF4 intel edition.

thanks! thanks! thanks!

try 115~ 120 mhz, look if you can up your corespeeds compared to stock PCI - E

From what I know, overclocking the PCIe bus does pretty much nothing because it is not remotely a bandwidth bottleneck. It may help marginally if you play games at very low resolutions, otherwise the advantage goes away as you increase the resolution.

I say this because nVidia debuted "LinkBoost" for the nF5 chipset, which auto-overclocks the PCIe bus by 25%. Even with SLI configs it didn't improve anything by more than 2 FPS at best from the numbers I've seen. Such as here: http://www.neoseeker.com/Articles/Ha...1XEM2AA/6.html

it does do something

overclocking the pci-e will! give you higher corespeeds, speaking at X1800XT,7900GTX level

Corespeeds? For what, you mean the GPU core??

i dont see how pci-e bus speed relates to corespeeds...

only nForce5 Linkboost does that with 7900GTX
