PCI-E Frequency

post #1 of 4
Thread Starter 
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?

Also while i'm here, would updating the Bios make higher overclocking possible?

@ PCI-E frequency:
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.

@ BIOS Update for OCing
For a GPU: No.
For a CPU: Kinda.
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
