Take a close look at the pictures below, which were taken using one of those fancy pants video microscopes. Manipulating the CPUs BP_FID multiplier pint and the “Golden Bridges” is a must. You'll see that the top right hand corner harbors the L1 bridges. An unlocked-ready Duron/Athlon will have the points on the left connected to their counterparts on the right. If not, then, you'll need to connect the points on the left by yourself and dig out a pen to do it with.
Here we have a Duron that is unlocked by Default.
This is our Duron 800, which is locked and has those little gaps, see?.
Here we used a slap-dash pencil and joined up the traces on our Duron.
Here we've done the same to our Athlon.
To overclock either the Athlon or the Duron we suggest using an “overclocking-friendly” KT-133 board such as the ASUS A7V or better still, the Abit KT7-RAID, currently the overclockers' AMD champion. Now it's time to start faffing about with the CPUs clock multipliers and FSB frequencies.
Another important point that “Scotty” on Star Trek was never too laid back about mentioning was “but Cap'n we need moooare powerrr!”. Hence be prepared to dabble a little with the voltage options in the BIOS. The Athlon by default is set to 1.75volts and upping it in small increments is going to allow you to get better results. The same goes for the Duron, which by default is set to 1.6volts. For those of you that have the stomach and heart of William Wallace, upping the Duron's voltage to 1.75volts can actually mean reaching 1GHz. Sound good? Thought so.
