AGP/PCI lock how do i turn it on or is it default?

yeah got an NF7-s yesterday and OC it immediatyely, well i never did figure out where i lock the pci bus, the agp has a fsb setting which i saw but where is the pci lock?????????? or does it just do it by default? also what is pci/agp spread spectrum?

pci is locked, no matter what. cant change it. its a feature of the nforce chipset,....... as for agp, its adjustable in the bios

They're both locked no matter what fsb you set. AGP is adjustable, PCI is not. Much better than old fashoned multipliers and makes it possible to run an XP 1700 at 3200 speeds and higher.
