i read this:

I did some research on this and found that on a overclocked 925x platform the nVidia bridged PCIe solution is stable to about 250 to 258 CPU clock on the Asus and other 925x motherboards and then it fails at any higher FSB. The ATI PCIe cards, on the other hand, continue on to the CPU limit of 278-283 or what have you.


now, my intel 3.0E is only running at 1.3875vcore when i get to 260 fsb, but any higher, and my video card (look in sig) refuses to post....so i was wondering if any of you guys with a similar configuration as mine was able to get past 260 fsb. and if so, how were you able to do it?

here is a quote i thought might be helpfull to you from toms hardware and the website.

"We also did not have much success with NVIDIA's GeForce 6800 GT, which does not take much more than about 260 MHz FSB and a correspondingly high PCI Express clock. Unfortunately, overclocking the system doesn't work very well when the PCI Express clock is limited to 100 MHz."

here is where the quote is located

i cant seem to find where they said it. but they also said that the X600 and above series handle the pci express overclock much better.which was why they used the x600(for lack of the X800Xt's availability) for thier benchmarks.
