The FX60 CPU was the fastest CPU of its generation.
At the time of its release in 2006, the FX60 was the pinnacle of consumer processing power. Priced at roughly $1,000 per unit, it was the fastest dual-core CPU using AMD's Socket-939, and it was the last processor in the "FX" line. What made the FX line truly unique, though, was its unlocked "multiplier." A CPU's multiplier is the ratio of the CPU's internal clock to the external clock (usually supplied by the motherboard). On a normal non-FX CPU, the CPU would have to be overclocked by leaving its multiplier at its default value while increasing the external clock speed. With the FX line, all you have to do is increase the unlocked multiplier for an instant overclock.
Instructions
1. Reboot your PC and access the BIOS. The access method varies from motherboard to motherboard but can typically be done by pressing the "Delete" key at the Power On Self Test (POST) screen. If "Delete" doesn't work for you, pay careful attention to the POST screen when booting up to find your BIOS access key. It is usually displayed along the bottom of the screen.
2. In the BIOS, locate the "Frequency, Voltages or Advanced" page. Wording varies wildly from BIOS to BIOS and can even change within different versions of the same BIOS. The page will have settings for the "Multiplier," "CPU, DRAM and Northbridge voltages." Consult your owner's manual if you have a difficult time locating the page.
3. Locate the option for "Hyper-Transport Multiplier." Its default is "5." Reduce it to "4."
4. Press "Enter" to select the CPU's multiplier. The FX60's default multiplier is 13. To overclock the CPU, increase it in increments of one.
5. Press "F10" to save your BIOS settings when you're satisfied with your multiplier value. Allow your PC to boot into Windows.
