Yeah, what it was is that 166mhz FSB chips sucked for FSB overclocking, and when hacked back to 133 they could go alot higher (stright past 166) for some bizzare reason. The same when they hacked 133's to 166, they suddenly sucked for FSB overclocking.
they did the 166 down to 133 because of some of the motherboards. Couldn't go past whatever fsb then doing the mod allowed them to go beyond 180 or 220 or whatever.
Modding a Barton 166 (perhaps a 200 too) to 133 worked on the ORIGINAL nForce2 chipset. I don't know if it works on the nForce2 Ultra 400.
Modding a TBred (b only?) 133 to 166 works on the nForce2 Ultra 400. I don't know if it works on the original nForce2.
You can do the wire-trick, that way you don't get crap all over the CPU and there is no visible evidence of tampering and try modding the CPU and see which way gives the best results.

There has been a lot on this issue of changing chips in both directions. I have included 2 links to threds with very extensive info on this.
