if your chip doesn't have the L1 bridges connected, which it probably doesn't, then you can only change the cpu freq to like 111, about 1.11ghz. Read some guides on unlocking the thunderbird/duron. If you unlock it then you can change the clock multiplier which will allow you to go to like 1.4+ with good cooling. I have a tbird 1ghz, but didn't want to take a pencil to it so i got a duron 600 and its exactly the same for unlocking it. i unlocked it fine and went to 1050. Its not that hard but i didn't want to have a tbird keychain, since the duron is only 50 bux it wouldn't have been much of a loss
