There are several new boards which are beginning to allow multiplier changes most with dip switches, MSI has just released a new board that I have heard overclocks like a demon. Abit claims that there board is more stable at 1 gig and beyond, It will just entail a lot of review reading on your part. You pencil the L1 bridges on the chip, I used a pentel automatic pencil with 0.5 mm HB lead. I had to do it twice the first time I didn't cover them enough. Just be careful not to cross connect the bridges to each other and if you make a mistake use the eraser and rubbing alcohol to clean it up and try again. My 700 duron is running 1050 on my kt7. Good luck. Be sure to use a quality heat sink and fan, alpha, global win, or taisol, because when you increase the voltage to overclock you really increase the heat in the chip
