5000 sequence with system bus speeds of 667 MHz, 1066 MHz or 1333

MHz, and core frequencies starting at 1.6 GHz.

CPU upgrading guidelines

When installing CPUs the following rules must be observed:

• Use only Acer-qualified CPUs.

• Each CPU socket include a CPU and heat sink.

• When two CPUs are installed, both should have identical revision,

core voltage, and bus/core speed values.

• When only one CPU is installed, it must be installed in CPU 1

socket.

• System is designed to provide up to 130 W of current per

processor. Processors with higher current requirements are not

supported.

To install a CPU:

1 Observe the ESD precautions and pre-installation instructions

described on page 39.

Warning! The heat sink becomes very hot when the system

is on. NEVER touch the assembly with any metal or with

your hands.

2 Remove the CPU air duct. Perform the instructions described in “To

remove the CPU air duct” section on page 45.

3 If installing a second CPU, remove the CPU air dam first. See

“Removing the CPU air dam” section on page 47.

4 Locate the processor socket.
