AMD Overclocking Guide

Overclocking via Software


Many overclockers out there know the versatility of overclocking and also what a pain in the butt it can be when you have to keep changing your front side bus settings. This requires a restart of the PC, entering BIOS and changing the FSB and then restarting back into the OS and testing. If this setting is right then you try to increase the front side bus and then go again which requires another restart. This can be a lengthy process especially if you are running Windows NT4 or Windows 2000, which takes a bit longer to load the Windows 9x operating systems. There is another way. Overclocking the front side bus by using software applications such as softFSB. SoftFSB works on the principal of altering the clock generator signals from within the Windows environment. This means that the CPU can be overclocked without having to restart the PC. All you have to do is select either the motherboard or clock generator that your board uses and they hit the "Get FSB" button and then softFSB will tell you your currant FSB and also give you a scale of what FSB's your board supports. The usefulness of this is shown when you want to try overclocking in small increments, i.e. changing the FSB one step at a time, this way you can select the FSB in windows, run the stress tests and find out whether the processor can take this speed and if it can you can proceed to the next level without having to restart the PC. After you find the sweet spot for the FSB then you can shut down the PC and make the adjustments to the BIOS to permanently use the speed you found in windows as its boot up speed. SoftFSB can't adjust the core volts of the CPU from windows so if the CPU requires more volts you will need to restart. SoftFSB is the only all-in-one FSB program that can work with just about all motherboards. Motherboard manufacturer FIC provide with their range of motherboard a program called Fuzzy Logic 2 which is a variation of the softFSB program designed for FIC motherboards. MSI also include a software overclocker called Busracing. This software is a variation also on the softFSB program designed for MSI motherboards.
