CPU voltage problem withP4B 266

Hi,
I just got 1.8A and P4B266 too, but I am having problem oclocking. I can only get to 129 FSB with 1.725 V! I also get lock up when I reboot.

One thing I noticed in the Hardware monitor and MBM is that no matter what voltage above 1.65 I set, thevoltage stays at 1.65V. I have the board over-volted too. If jump the board for non-over-bolting then the voltage reads 1.5v no matter what CPU voltage I set.
Please help I think there is something wrong with my motherboard. I tried 2 different power supply. Please help!

The board's over-volted, meaning you did that CPU pin-tying trick? If so, I think that's supposed to "lock" your voltage to the chip's maximum (1.65 I'm assuming). Maybe undoing the wire, and using only the BIOS voltage settings will help?
