p4 ddr boards that support PCI "clock lock"

[natopotato]

i'm currently thinking about using a 1.6gig northwood in a new system soon. needless to say, i plan on OCing the snot out of it. anyway i was wondering which boards allow you to lock in the PCI/AGP clock at nomial speeds. i've heard the ASUS p4b-266 can do this. are there any others? i'd be particularlly interested in whether or not the Abit SD-7 533 has the feature.

thanks in advance

I dont think that it can. Based on what I have been able to find, the P4B266 at 133FSB and above will use 1/2 for AGP, 1/4 for PCI, and 1/1 for MEM. Check here. The only board that I know of that can lock at 66/33 AGP/PCI is the Abit BD7 but I have read bad things as far as stability for the BD7.

Epox 4bda manual says in auto, if fsb>117 then agp/pci fixed to 66/33. Also options are auto, agp-fsb*2/3 pci-fsb/3, agp-66 pci-33.

My ABIT SD7-533 does NOT ! Lotsa overclocking ratios,but no pci-lock feature in the BIOS.
