Geez, I though I was the only one who was using technology this old!
Thank god AMD dropped their prices, now I can afford to upgrade.
I've got almost the same CPU as you. I'm running a P2 - 266 that is overclocked to 338. How far you can overclock yours depends on your cpu and motherboard.
First, the chip. Intel made the P2 300 with 2 different cores. The first ran at 2.8V (Klammath) and they also made some at the end of it's life that ran at 2.0V (Dechutes).
Check your bios or a motherboard monitoring utility and find out which one you got. (Prey you have the latter)
Now check out this link:

and get your soldering gun warmed up if your motherboard doesn't support voltage settings.
If you've got a 2.0V P2, increase the voltage to 2.2V or 2.4V if you've got a really good HS/Fan combo. (Cover the appropriate pins)
If you've got a 2.8V P2, increase to 3.0V or 3.1V/3.2V if you've got a really good HS/Fan and don't mind running with your case open.
(Solder the appropriate pins together)
Next comes the mobo. The mobo you are using is LX chipset, so the max FSB you can use is 83. First check the chip multiplier tho! My P2 266 runs at the 300 multiplier with no probs (4.5 instead of 4.0) If you can only use a 4.5 mult, these are your options:
4.5x66=300
4.5x75=338
4.5x83=374
If you can use a 5.0 mult, these are your options:
5.0x66=333
5.0x75=375
5.0x83=415
That's it. Can't get anything more out of this cpu without a mobo that will do a 100fsb at the least.
My advice is to run out and buy a new athlot 1.2 to 1.4 as soon as you can cause AMD likely has something big and new in the wings with the mega price drops they just did. Chances are they're getting rid of a huge surplus of old stock cause computer sales are so slow right now.
Oh, and buy ram!!! With the 845 chipset coming out now, pc133 is back in major fashion and the price is gonna spike next month. Mark my words!
