Question about AGP/PCI?

[D4rKCyclonE]

In my bios there is an option for

AGP/PCI Frequency (Mhz)

What is this and what does it do?

 

[I.M.O.G.]

It sets the frequency for the AGP and the PCI bus.

AGP = 66 Mhz
PCI = 33 Mhz

Ok, and would setting it higher increase performance? And are there any risks? And what would be the highest I should set it at?

Leave it at stock. Any performance increase is almost negligible. Increasing the PCI and AGP clocks usually just results in system instabilty, video card artifacts, lower video card OCs, and data corruption...it's much better left at stock.

Yup, leave them at stock.

Instead of overclocking the AGP bus, overclock your vid card using something like powerstrip.

Nothing on the PCI bus should be overclocked to increase performance, PCI cards do not have anything to benefit from it and it only causes problems for HDDs.

or destroyed cards, i lost a 9700 pro aiw to a overclocked agp bus. there was no oc on the card or volt mods.
