system spec:
AMD Barton XP 3000+(@2345Mhz) 1.85v 13x180
(stock is 13x166)
SI-97 & YS-Tech HSF
NF7-S (rev.2) (current bios: mantaray xt d26 cpc-off)
2 SATAs (240GB)
1.5 gig PC3200 value RAM (DC)
PNY 6600GT + VF700 (@569/1125)

my problem is this:
i can only use odd number multipliers. 13 is stock, 11 works, and 9 works. My CPU works fine at any of these multipliers.
If i want to use any multiplier in between, i can set it in my bios, but when my PC posts, it reverts to the nearest lower odd number multiplier. e.g. if i set my multiplier as 12, save, reboot, comes out at 11. If i go back into the bios it still says 12, but really is running at 11. WTF?
I have tried with original Abit bioses, and the same thing happens.
I have asked this question on many forums, and no one seems to know the answer (no one ever heard of it before).
Surely someone somewhere knows what is going on.

Just a WAG, but I wonder if that's a CPU pin broken or something like that...

A single pin in binary wouldn't do exactly what you described based on how I thought the multiplier pins worked - but I'm too lazy to go research it and I don't remember it from previous research.
