help with celeron 1.2a overclocking

[tenest]

i'm trying to overclock a celeron 1.2a (tualitin) on an Abit VH6T. It is ROCK-SOLID stable at 123 fsb (12X multiplier) and 1.5v. i've run CPUStability on it for 14 hours without one problem or glitch. however, if i try to bump it past 123fsb, even just to 124, it refuses to post. i'm assuming it's because the video card doesnt like the odd timing (124/4 = 31). if i bump it up to 129fsb and push the voltage as high as it will go (1.575) then i can get it to boot into windows and its fairly stable. if i push it to 133fsb, it will post but it hangs as soon as it starts to load windows. i'm pretty confident that if i could bump the voltage up to 1.625 or maybe 1.65 then it would run perfectly. but the mother board refuses to let me go that high. is there a secret to getting around the voltage lock?

i KNOW someone out there has run into the same thing. if you could point me in the right direction, i'd REALLY appreciate it!

I think this is what you are looking for here!

Yes, try the wire trick to increase your VCore to ~1.80v. With that try and my VH6T I'm able to run my 1.0A to a FSB speed of 153MHz. A real nice & fast system indeed... With the trick the boot-up voltage will be 1.675v and you will be able to set it in the BIOS up to 1.775v which gives a nominal 1.8v to the CPU.
