Installing Hardware
Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure
that you DO NOT scratch the motherboard or any of the surfacemount resistors with the clip of the cooling fan. If the clip of the cooling
fan scrapes across the motherboard, you may cause serious damage
to the motherboard or its components.
On most motherboards, there are small surface-mount resistors near
the processor socket, which may be damaged if the cooling fan is
carelessly installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you
can clearly see the motherboard and processor socket.
Before installing the Processor
This motherboard automatically determines the CPU clock frequency and system bus
frequency for the processor. You may be able to change the settings in the system
Setup Utility. We strongly recommend that you do not over-clock processors or
other components to run faster than their rated speed.
Warning:
1. Over-clocking components can adversely affect the reliability of the
system and introduce errors into your system. Over-clocking can permanently damage the motherboard by generating excess heat in components that are run beyond the rated limits.
2. Always remove the AC power by unplugging the power cord from
the power outlet before installing or removing the motherboard or
other hardware components.
This motherboard has an LGA775 socket. When choosing a processor, consider the
performance requirements of the system. Performance is based on the processor
design, the clock speed and system bus frequency of the processor, and the quantity
of internal cache memory and external cache memory.
Fail-Safe Procedures for Over-clocking
When end-users encounter failure after attempting over-clocking, please take the
following steps to recover from it.
1. Shut down the computer.
2. Press and hold the “Page Up Key (PgUp)” of the keyboard, and then boot the PC
up.
3. Two seconds after the PC boots up, release the “Page Up Key (PgUp)”.
4. The BIOS returns to the default setting by itself.
