Overclocking With Msi Kt4-ultra

[UAH_Alucard]

Hello, everyone. I have a few things for this post. Firstly, I am running an XP 2100+ Thoroughbred B0 (Stock 1.7 GHz at 13x133) and I'm currently overclocking to 2.17 at 13*166 with 35'C idle and 42'C load with Corsair XMS PC3200 2-3-3-6 and 1.675 volts air cooled by a globalwin TAK68+. I was wondering if that was a decent overclock for this chip. I've seen a lot of people get a lot higher. Also, for the love of all that is Holy, I cannot get this board to change the multiplier. I've flashed to the latest bios and everything and I have a B0 core so the chip should be unlocked but everytime I try to change the multiplier, it won't POST. I want to maybe down the multiplier and up the FSB since I know my RAM and my board can handle it. Any help would be greatly appreciated.
