Need advice, Newbie o/cing the VH6T

What's the best method to o/cing the VH6T in the softmenu3? I've tried raising the multiplier, but I'm getting hints that the chip is automatically defaulting to factory settings. It's a p///800 w/ win98se. If I remeber correctly, Pentiums are internally locked for the multiplier, right? So, the only o/cing that can be done is raising the fsb and vcore?
After raisinbg the multiplier, I reboot and the softmenu says it's at 6.5 and default was 6.0. Any and all advice is greatly appreciated
