"This is a guide to show you how to unlock the AMD T-birds and Durons via a pencil. Why AMD had overlooked this simple trick I cannot say and when they will bury the bridges under the ceramic plate I cannot say. Obviously AMD is aware of this, and they might bury the bridges when they move to the .13 micron process, but for now we can enjoy unlocking our processors with a simple pencil. Some people have processors already unlocked (early production) where the L1 bridges are connected, AMD was quick to implement a laser to cut these 4 bridges leaving us with locked multiplier processors. Luckily such low voltage runs through these bridges simple graphite found in normal #2 pencils is good enough to conduct and give us unlocked processors. Usually, a pencil containing low amounts of clay and high amounts of graphite work better to unlock processors because clay only prevents conduction. Pencils such as 5h are optimal for the unlocking process, usually anything 2h or more is good enough though, these are hard pencils since they have low clay content (used to soften the lead piece) and high graphite content. Since the local Walgreens here didn't carry anything other than 2hb pencils (Normal #2 pencils) that is what I will use in this article. The exact pencil I used was a mechanical pencil with .5mm lead, thinner is better."
