Question regarding PCI bus OC

[HungLo]

When I'm overclocking my PCI express buses should I run them at a speed that matches my graphics cards bus bandwidth? That is, if I had a 7900gt I would set my bus speed to 256mhz or more specifically in my case with 2x7600gts would I set my buses at 128mhz? Or does that matter? Kind of a noob question but what the hell?

I can pretty much confirm...

nVidia got a feature called linkboost that OC the Ht PCIe and maybe the HT connection too, been shown not to improve the performance. I wouldn't bother and simply run it at default speed.

It can help to lock at 101Mhz if youre having video problems while OCing, but useless to run it different from stock otherwise.

Speaking of stabilty. When I overclock this evga mobo (I'm currently @ 9x multiplier for a 3.3gig clock speed) , my logitech mouse acts a bit buggy from time to time. Like if I move it accross the screen it pushes a button and I didn't push nothing??? Should I try lowering my voltages again? What part of my mobo would control this issue?

Add a notch to ICH, if that doesnt work, bump MCH a few notches at a time.

I tried like you guys said and bumped up the volts! Didn't work... Thanks, butlater that night found the answer @ EVGA. I was using the PS/ 2 inputs on the back of my mainboard for mouse and keyboard so since switching to USB it hasn't been a problem?!?

New boards, always full of glitches. Thanks for the info tough, im sure it will come in handy. Glad it worked out
