There is an option to change the PCI-E frequency from 100Mhz upto 145Mhz in the Bios, why is this option there? Changing this would surely damage your GPU or make it run extremely hot wouldn't it?<br><br>
Also while i'm here, would updating the Bios make higher overclocking possible?

@ PCI-E frequency:<br>
I heard, but I don't know if its true, that ATI is best to be at 105Mhz, Nvidia at 100Mhz. I had mine to 118Mhz before, and at 105Mhz my 3DMark05 score grew about 200 points at stock, but my max OC for my GPU dropped quite a bit. No idea why. The difference between 105Mhz and 118Mhz was like 50 points, and its a pretty bad idea to do it any past 5/8 or so, so yeah. I keep mine at 100 to be safe and just OC.<br><br>
@ BIOS Update for OCing<br>
For a GPU: No.<br>
For a CPU: Kinda.<br>
Only way it would help a cpu is a limit of the HTT/FSB being removed. I couldn't get past 244HTT before I flashed mine to a newer version.

Increasing your PCI-E Frequency can give you better 3D scores, but it could also corrupt your OS <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile">
