OK... Cheg... the fifth number stands for the type of core that is under that plastic box... 2 stands for Klamath and 3 stands for Deschutes. You have number 2 so that sucks. Normal PII300 (Klamath) comes with 6.5 or even 7 ns cache which don't give you much space for o/c-ing (Maybe up to 350Mhz)...
But the second row shows something interesting...

R stands for Phllippines, 7 for year 97 and 42 for week 42 of that year...
That means that it's very likely that your CPU isn't multiplier locked (Intel locked all their CPU's to one multiplier somewhere in the middle of 1998) so you could, in a mobo that supports 100 Mhz bus speed set your processor to work 3x100=300 Mhz which is significantly faster than 4.5x66=300 Mhz.
You could even try a 3.5x100 setting but that isn't guaranteed to work...
I suggest you get a new mobo (ABIT BH6 is cheap and most stable but ABIT BE6 is much better giving you two additional U/ATA 66 channels with other features pretty much the same). That way you can still yank something out of that PII300 and when the time comes you can stick in the mobo any Slot1 PIII processor that is currently available including the coppermines...
