ABIT's CPU Accelerator How-To Guide
Get 33% faster performance in four easy steps

November 12, 2004 – Released earlier this week, ABIT's CPU Accelerator technology allows the user to adjust the multiplier of Intel Pentium 4 CPUs, and boost the overall performance of their PC. The following guide takes you through step-by-step on how to boost your front side bus (FSB) speed from 800MHz to 1066MHz. CPU Accelerator is a quick and easy way to get free performance from your system. In-house testing has shown gains of 33% or higher in four easy steps!
A word of caution:
As with all overclocking, ABIT can neither guarantee results, nor be responsible for damage that may be caused to your system by running it beyond normal specifications. Do the following at your own risk.

Step 1: Know your system configuration.

It's important to know what kind of CPU and FSB you are running. For this demonstration, we are using a 3.6GHz Intel Pentium 4 processor, and running an FSB speed of 204Mhz. You can see that the CPU multiplier is currently 18.

Step 2: Enter the BIOS

The BIOS handles the basic operating parameters of the system, including things like CPU speed and memory settings. When you are booting the system, press the DEL key to enter the BIOS.

Once you enter the BIOS, set the CPU Operating Speed to User Define.

Step 3: Change the system settings.

Here's the fun part. Using your keyboard arrow keys, change the following settings:

External Clock > 266MHz
Multiplier Factor > X 14
N/B Strap CPU As > PSB1066
DRAM Frequency > DDR533

Step 4: Save your new settings and reboot.

Press F10 and save and exit the BIOS. After rebooting, recheck your system configuration.

As you can see, the CPU is operating at 3.72GHz, and the FSB is running at 267MHz (1066MHz quad-pumped)!

Congratulations! You've now just increased your system performance by 33%.
