Overclocking by Multiplier Manipulation
Many people have emailed me and ICQ'd with this big statement, "AMD promised to support the overclocker, they said that they wouldn't lock the multipliers." In 1 was this statement is true and in another its false. The multiplier factor is soldered onto the Athlon CPU's but they can be manipulated with some simple modifications.
For the Slot A range of CPU's you can buy a overclocking tool called a "Goldfinger Device." This device plugs onto the expansion port that AMD put onto the Athlon Slot A PCB. When powered this device uses a series of resistors to change the voltage received by the CPU from the motherboard and intern changes the multiplier this way. There are many overclocking devices for AMD Athlon Slot A CPU's on the market and just about all of them are good enough for use on the Slot A Athlon, this applies to the Slot A Athlon Classic and Slot A Athlon Thunderbird.
For Socket A processors like Athlon Thunderbird and Duron the process if a bit different. Since there is no PCB for the CPU there is no Goldfinger expansion port, however multiplier adjustments are available by connecting the L1 bridges together on the CPU. When connected these bridges allow electrical currant to flow to the 4 extra pins on the bottom of the Socket A CPU. A motherboard with multiplier adjustment capabilities is then required to allow multiplier manipulation. Unfortunately there aren't a great amount of boards out there with this feature at the moment but we have seen this feature take hold on a few companies with multiplier motherboard out now and other companies announcing board with the multiplier adjustments onboard. At the time of writing this review the only motherboard with multiplier adjustments either in BIOS or jumpered are; ABIT KT7 (RAID), MSI K7T Pro 2, EPOX EP-8KTA+, ASUS A7V and the ASUS A7 Pro.
This comes in handy as this way you only have to worry about overclocking the CPU and not have to worry about the other preferables in the PC like video card and memory as they are unaffected by this type of overclocking. This gives AMD K7 another advantage over Intel CPU's.
