Eliminate Restrictions and Power Your CPU ASUS Motherboards Unlock FSB Overclocking Limitation
Taipei, Taiwan, September 21 2004 – Every user with some experience on computer hardware knows this formula
CPU operation speed = FSB frequency x CPU multiplier
Users tweak their systems either by increasing FSB frequency or CPU multiplier, which is usually locked for the Pentium 4 CPU when purchased of the shelf, greatly limiting your overclocking options.
Here's the good news for overclockers!! ASUS Motherboards now offer the CPU Lock Free feature, which allows you to adjust CPU multiplier to 14x. The reduction of multiplier value provides more flexibility for increasing external FSB frequency to raise memory bus bandwidth.
The following example demonstrates the effectiveness of CPU Lock Free. As the table indicates, CPU Lock Free adjusted CPU multiplier from 18x to 14x, allowing the system to operate with FSB frequency up to 258MHz(maximum bandwidth 8.23GB/sec) and memory bandwidth up to 10.98GB/sec while CPU operation speed remained at 3.6GHz.
CPU Lock Free boosts overall system performance by making synchronous modification possible. Enjoy better performance at the same CPU operation speed and improve your system without pushing the CPU to the limit.
