Hi all! I'm a newbie at this , I'm running PIII 733/CUVX M/B, Hundai P133 cas 3 sdram/256mb, Matrox G400 max V/C, the PIII is cB0 stepping, 2 case fans. So far what I've done is up the FSB to 146 and the voltage to 1.7, so I'm running at 803 mhz, stable(one random reboot in 2 days don't know if it's related) , and cool at 21c. Is there anything I'm doing wrong so far? And what more can I do? Thanks!

You're on the right track- keep an eye on cpu temperature and move it up a little. Watch for symptoms of instability, and once you discover where this occurs, the task of determining the cause begins. Starting out with an EB chip makes it a little harder, but you're doing fine so far.

Thanks Tim, so you are saying basically continue raising the FSB, should the voltage go up as well as I do this (forgot to say I'm running a 300 watt P/S) I don't know the function of the voltage in this process.

Increasing the Vcore is sometimes necessary to achieve stable operation at increased FSB. Some chips will run at default voltage, others (most I have played with) need a little more to operate properly at higher FSB. Don't exceed 1.85-1.9v Vcore- at least not until you KNOW the characteristics of your setup. Increasing the clock speeds increase the temperatures, and increasing Vcore does it ever worse. Keep a close eye on temps as you proceed.

The 300W figure of your PS is a capacity rating. It can provide up to 300W but the actual dissipation will be determined by the consumption of all of your active devices.

Awesome help thanx.....one last question though, is there anything I have to worry about regarding the over clocking this will cause to my V/C as I raise the FSB.

It's not going to make life any easier for it, but I doubt that it will cause any real problems. I have a card running at 97MHz AGP right now on a BX board with 146FSB. I added a fan to the heatsink on the video card, though...
