Over-clocking information
Over-Clocking: Users accept all risks in over-clocking the system when the "CPU Clock" in the CMOS BIOS is selected to be higher than 100Mhz.

Basically, the Athlon System Bus in the SCE USA^tm771ASIR board operates at 200Mhz, double the speed of the memory bus. The BIOS has a spot that allows you to adjust the "CPU clock" speed from 95mhz up to 133mhz. The so called CPU clock is on an old Intel conventional term where the CPU bus was the same as the memory bus. This "CPU clock" is the memory bus clock speed only; whereas the Athlon System Bus (the true CPU clock) operates at twice the memory bus clock speed.

What it comes down to is that this BIOS setting allows for over-clocking. This board is now shipped with Auto Detection mechanism to boot up correctly. The only time you would need to go into BIOS's Frequency area is to over-clock.

For example, if you have an Athlon 600Mhz CPU and leave it at default "CPU clock" speed, which is 100Mhz, then the Athlon System Bus speed will be running at 200Mhz and the actual CPU internal speed will be running at 100x6=600Mhz.

If you are in the mode to try over-clocking, you could go into the BIOS and change the CPU/PCI clock speed to 105/35Mhz. What this does is that the memory will run at 105Mhz and the PCI will run at 35Mhz. The Athlon System Bus speed will be at 105x2=210Mhz. And the actual CPU internal speed will be running at 105x6=630Mhz ! If it boots up, it will show 630Mhz on the boot-up screen.

    Of course, the standard disclaimer goes -- try it on your own
    risk. If it doesn't boot up, you can shut down the power, hit the
    power button, and hold the "insert" key to get the screen back
    and change the CPU/PCI clock speed back.

The SCE USA^tm 771ASIR stands equally against the top 5 brands in quality and performance even before the bundling. With the 4X USB ports, IR Drive, and free unlimited internet access
bundling, it provides an high performance total solution package at an affortable price point.
