Little OC help with an old chip?

[sp00]

Let's start out with my system specs... just to put me in on the ground floor.
So I've got an old Thunderbird 1.4 that came with an unlocked mulitlpier. I'm using it with an Abit NF7-S v2 and 768 of PC2100 (1x512, 1x256). I've also got a decent PSU (AntecTrue380) and a decent video card (Asus FX5600 with 256mb), so no worries about those yet. Anyway I wanna OC my chip to see what it can do. I'm not to worried if I fry it becuase it gives me a good reason to upgrade. The HSF on my proc is a Coolmaster HHC-001 (the heatpipe one) with a decent 5000rpm fan.
Right now I've upped the FSB to 137 and the multiplier to 11. It's doing 1504mhz @ 43C without any problems.I've played around with the setting a little, but never was serious about OCing. Can somebody explain to me how to go about changing things (voltage, FFSB, and mult) to get a good OC outa this chip?
TIA

First thing I would is drop the multiplier low then start increasing the FSB to see where that tops out at. Then slowly raise the multiplier until you find where the chip is no longer stable. Then start increasing voltages.

along the way, TortureTest it (use Prime95 www.mersenne.org) to test for stability; this tests both RAM and CPU, if it has an error, you aren't stable (even if you CAN load Windows...)
