PCI-E frequency clock

[Asjasck]

My PCI-E clock rate now is 100mhz. What happens if i add the frequency to a higher number with a new frequency of >100 mhz. What is the best clock frequency?

 

[Asjasck]

The OC utility that came together with the GC has a limited overclockability. So i was wondering if add the frequency on the PCI-E bus would do any good?

The default clock rate of the PCI-E is 100mhz right?? So i should keep it at that frequency?

All PCI-E bus default clock rate is 100mhz right? I forgoten.

How do i reset my BIOS settings to factory settings?

Thanks.

If i clear my CMOS, all BIOS updates would be gone?

After clearing CMOS, BIOS settings are default? Or do i need to set value like clock rates and other settings?

The motherboard i'm using is Abit K9 SLI.

Owh okay.

I know this is weird, but using nvidia ntune it shows that the frequency at my PCIe bus is 2500.000mhz. Why is that so?

Thanks.

Generally PCI-E clock speeds are of little help when overclocking.However,sometimes upping the frequency slightly will help with over all system stability.Playing with the PCI-E bus frequency should be left to the serious over clockers.Unless of course you can afford to burn out your system and replace it as needed.I personally have seen no benefit from changing the PCI-E frequency,so I decided to leave it at 100mhz.I had more luck when I changed voltages on my hypertransport bus and memory and cpu frequencies.Goodluck.

When in Ntune your now looking at the Video card and not the PCI-e bus. I beleive your looking at the memory spped.

I'm not very sure

Here's the screenshot of my nTune.

By the way what is the nForce fans and aux2 fans?

Thanks.

 

[Asjasck]

Somebody answer me please.

Thanks.

The nforce fan on a NVidia board would be the fan cooling the northbridge.
The aux 2 fan should be a case fan connected to the mobo but there is no way it is spinning 30,000 rpm, so nvidia monitor isnt reading it right.
