I'm currently running at 66.66/33.33...
I see some people who wants the agp/pci lock.. why ?
Doesn't upping the settings increase performance ?

what is the process of finding the optimum setting?
change setting, reboot, test, change setting, reboot.. etc?

Hard drives surely don't like high PCI clocks. I've heard about a Seagate Barracuda IV developing bad sectors at 36Mhz.... Mine run @37,5 for 3 weeks and have the same problem...

To be safe it is best to keep your PCI/AGP setting locked when upping your FSB. That way you'll at least avoid problems in that department, and focus on getting the rest of your overclock stable.

With boards without a locking feature, a lot of times the PCI cards are a limiting factor in how high you can OC the system.

With my new Albatron board, I can lock the PCI/AGP divisors and completely take them out of the equation when I overclock.
