OC the AGP / PCI bus?

[CSiborg]

I've read somewhere that you can OC the AGP bus to run at higher than 66mhz (75mhz being fairly safe) and get a tad more video performance. Can anyone confirm this is fairly safe and will speed things up a bit or is it not worth the risk? The only side effect would be the PCI bus also being OC'd on my system which would again be minimal but I cant imagine what it would cause to go wrong.

unless your board supports pci/agp freq locking, as you move the fsb up the pci and agp bump up accordingly :)

Yea, this mb does support locking, it also supports your typical ratios for the FSB > AGP/PCI bus as well as custom ratios I do believe. I suppose their is only one way to see if it will make a performance difference or not and that is to try it out for myself.

Edit: Humm yea that didnt work... I guess i'll stick with default settings.

Yeah I've tried that before too ... but even with only 2mhz overclock things started going haywire! Might be cause the FSB is so high already, that it doesn't like the rest of it being bumped up! :D?

AGP/PCI buses run out of spec = BAD.

Yes, some performance can be had, but that is at the expense of running your HDs, PCI cards, Vid card, and anything else out of spec.

In the "old days" that's just what you had to do. But now that there are bus locks...use them. I've toasted a few OS installs and a few HDs by running things out of spec for long periods.

It's not worth the performance IMOHO.
