2.2 CPU (Central Processing Unit)
The mainboard supports Intel® Core 2 Duo/Core Duo/Core Solo pro-
cessors. When you are installing the CPU, make sure the CPU has a heat
sink and a cooling fan attached on the top to prevent overheating. If you
do not have the heat sink and cooling fan, contact your dealer to purchase
and install them before turning on the computer.
Note
(1) Overheating will seriously damage the CPU and system.
Always make sure the cooling fan can work properly to
protect the CPU from overheating.
(2) Make sure that you apply an even layer of heat sink paste
(or thermal tape) between the CPU and the heatsink to
enhance heat dissipation.
(3) While replacing the CPU, always turn off the ATX power
supply or unplug the power supply’s power cord from the
grounded outlet first to ensure the safety of CPU.

This item controls the number of cycles for Row Address Strobe (RAS)
to be allowed to precharge. If insufficient time is allowed for the RAS to
accumulate its charge before DRAM refresh, refresh may be incomplete
and DRAM may fail to retain data. This item applies only when synchro-
nous DRAM is installed in the system.
