Upgrading the CPU
The server supports two dual-core Intel Xeon processors 5000 sequence
with 2 x 2 MB L2 cache and 1066 MHz or 1333 MHz FSB.
CPU upgrading guidelines
When installing CPUs the following must be observed:
• Use only Acer-qualified CPUs.
• Each CPU socket include a CPU and heat sink combination.
• When two CPUs are installed, both should have identical revision,
core voltage, and speed values.
• When only one CPU is installed, it must be installed in CPU 1
socket.
To remove a CPU:
If you are replacing a CPU on the system, the heat sink must first be
removed.
Important: Before removing a CPU from the mainboard, make
sure to create a backup file of all important data.
1 Observe the ESD precautions and pre-installation instructions
described on page 35.
Warning! The heat sink becomes very hot when the system
is on. NEVER touch the heat sink 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 42.
3 Locate the CPU you want to remove.
