Chim3Ra ,

I set it to 100mhz, but the computer acted weird and didn;t start up properly, I set it back to auto for the moment. I am going to install IA Booster from ASUS mobo's software to get into more details , in order to get the picture across

See you

That has got to be the funnyest statement I have ever heard from an overclocker! If it couldn't be changed there wouldn't be an option, whether you do it right or not will determine whether or not your gonna fry anything.

Asus/nVidia has a program called nTune. It can tune your overclock for overall memmory, hard drive, graphics, or overal system performance. I used it for graphics, and it adjusted and tested video card clock speeds HTT and PCIe bus. It pumped the PCIe bus to 113mhz.
So using that information I manually overclocked and tested things and have the PCIe bus overclocked at 115mhz. As far as performance gains, it gained 400 points in 3DMark05. So it does do something for performance, but it may depend on your configuration. I run two 6600GT's in SLI, which means the PCIe bus width is only 8x per card instead of 16x for one, I believe this is why the overclocked PCIe bus has gained some performance.
Your vid card will see increased temps from overclocking the PCIe bus though, so just watch the temps, and for artifacts.

HELP HELP

When I change from "Auto" to 100 in advance section jumperfree setting, the system won't start. Even worse the monitor doesn't receive any feed from the computer and so goes to sleep. Computer doesn't start up

Please explain

May this have anything to do with my system ocasionally resetting out of the blue when surfing the web or watching movies ?

Chim3Ra, I am currently overclocking an Cedar Mill 631 from stock 3.0 to
3.7 Ghz having the FSB to 250 at the moment running a stock fan.

What kind of Cooling do you use ? Do you recommend anything?

I use a Thermalright XP-120 (http://www.svc.com/si-120.html). Others have had really good results with the Thermaltake Big Typhoon (http://www.svc.com/cl-p0114-14.html).

If they can fit your motherboard, I would get either of those. If they don't fit there are two smaller alternatives, the XP-90 (http://www.svc.com/xp-90-21.html) or the XP-90c (http://www.svc.com/xp-90c-21.html).

If you decide to go with any of the Thermalright's you'll need an LGA775 retention bracket (http://www.svc.com/lga775rm-21.html) as well.

Somewhere in the forum is a thread that will tell you that the "sweet spot" for ATI cards is 105 mhz; that is what I have mine set at and it seems to work great.
