Page 13
2.4.2. Memory Modules
The mainboard has three 184-pin DDR DIMM slots which are located on the
right-hand side of the board. To install the DIMM’s into these slots, make
sure the white lever at each side of the slot has been pulled down to an angle
of approximately 45°. Make sure that the DIMM is in the correct orientation.
Place the DIMM on the slot and push down firmly.The white levers will come
back up and lock the module in place.
Hardware Installation
2.4.1. Installation of the CPU
To install your processor, please complete the following set of instructions:
1. Locate a small dot marked on the top of the CPU. This mark indicates Pin
of the CPU.
2. Locate Pin 1 for the Socket on the mainboard.
3. There is a lever on the side of the socket. First push this lever sideways
and then lift it to a 90-degree angle.
4. Insert the CPU into the Socket. Please make sure that Pin 1 for the CPU is
inserted into Pin 1 of the Socket.
5. When the CPU is installed correctly push the lever back into place.
6. Install a proper heat sink with cooling fan for proper heat dissipation.
Failing to install a heat sink with cooling fan may cause overheating which
will burnout your CPU and damage your mainboard.

IMPORTANT: CPU COOLING FAN
Please ensure that you have an approved heat sink with cooling fan. Without a
proper heat sink with cooling fan
you will damage both the mainboard and the
CPU.
Important: The DIMM’s can only be fitted into the slots in one orientation.
Make sure that the DIMM’s are in the correct orientation and the pins are cor-
rectly aligned before you insert them.
