How to overclock a 1.7Ghz Celeron

[Pray For Death]

Hi
I have a 1.7Ghz Celeron with a locked multiplier in a Gigabyte GA-8ID533 (Rev 1.0) motherboard and a 350W PSU, after reading some reviews, I noticed that most of the people were able to overclock the FSB easily to 133Mhz with some little voltmodding, so they get around 2.26Ghz with their Cel.
My question is, how do I voltmod my CPU? And what's the highest (and still safe) voltage for my CPU?
And How do I unlock my CPU's multiplier? I can do a hardmod if I had to, don't worry.
I know that I can raise the FSB's speed using my Mobo's bios. But as I said before, the multiplier is locked, so when I raise it nothing happnes.
Any help would be apreciated.

The 1.7GHz Celeron is a Willamette core and I don't think it's common to expect a 33% overclock even with extra voltage unless you've pretty lucky. The Northwood Celerons and the new Prescott Celerons do overclock pretty well. The Willamette Celerons were never great overclockers.

Like most P4 overclocking, you don't use a "volt mod", you just increase the voltage in CMOS setup. If you don't have voltage options, then you would short pins together to increase the voltage (or more correctly, tie the pin to Vss with a resistor). Secondly, you can't unlock the multiplier. Some engineering samples come unlocked from Intel, but the locked CPUs are not unlockable by end users at all.

If you are raising the FSB (not changing the multiplier) and nothing happens, maybe your motherboard is resetting back to default FSB after a failure... or the overclocking features are not working. Take a smaller step (5MHz) and verify. If you don't have FSB or voltage options in setup, forget about overclocking.

Increasing the FSB works for me, so far I've managed to get as high as 2Ghz, and looks like I've reached the ceiling, when I try to go higher, the PC becomes unstable, and sometimes it doesn't boot up.
Can you provide a link describing "increasing the voltage" process?
I thought increasing voltage means volt-mod, if not, then what exactly is it?
Thanks
