Chapter 2 Hardware Installation Process

Installing the Central Process Unit (CPU)

CPU Installation

1. Unlock the CPU socket by pulling the lever up to a 90-degree angle.

2. Position the CPU above the socket such that the marked corner (pin1) matches the corner near the

base of the lever.

3. Place the CPU into the socket. If the CPU is unable to insert properly, check its orientation and

attempt to re-install.

Warning! Do not force the CPU into the socket. Doing so will prompt bending of the pins and create

damage to the CPU.

4. Close the socket by lowering the lever and locking the lever in place.

Installing Memory Modules

1. Push the white retaining clips on each of the memory socket outwards.

2. Match the notches on the contact edge of the memory module to the ridges in the memory socket.

3. Insert the memory module vertically into place. When properly inserted, the white retaining clips will

move inward to lock in the module.

4. Repeat installation process when adding additional modules.

Double-sided DDR modules can be plugged into either DIMM2 or DIMM3 only.

DIMM2 and DIMM3 only can plug single side DDR (DIMM2: single side, DIMM3: single side)
