CPU: 940-Pin AM2 Socket Supporting AMD AthlonTM 64 / 64FX / 64X2 and
SempronTM Processors
Supports AMD’s Cool ‘n’ QuietTM Technology
FSB: Hyper Transport 1000 MHz
Memory: 4 x DDRII DIMM Slots: DDRII_1, DDRII_2, DDRII_3, and DDRII_4
Support DDRII800 / 667 / 533, Max. Total Memory Size 8GB
Dual Channel Memory Technology Support
NOTE
AM2CPU Board provides four 240-pin DDRII (Double Data Rate) DIMM slots, and supports Dual
Channel Memory Technology. For dual channel configuration, you always need to install identi-
cal (the same brand, speed, size and chip-type) DDRII DIMM pair in the slots of the same color.
In other words, you have to install identical DDRII DIMM pair in Dual Channel A (DDRII_1 and
DDRII_2; Yellow slots) or identical DDRII DIMM pair in Dual Channel B (DDRII_3 and DDRII_4;
Orange slots), so thatDual Channel Memory Technology can be activated. It also allows you to
install four DDRII DIMMs for dual channel configuration, and please install identical DDRII
DIMMs in all four slots. Please note that only theDRAM configuration according to the Allowed
DRAM Configurations Table below is workable. Do not make any DRAM configuration
that is not listed on the Allowed DRAM Configurations Table.

AM2CPU Board Installation
To install AM2CPU Board into the Future CPU Port onASRock motherboards that support future
CPU upgrade function (e.g. K8Upgrade series motherboards), please follow the steps below.
STEP 1: Install the AMD 940-pin AM2 CPU into AM2CPU Board, then install the CPU fan and
heatsink into AM2CPU Board, and connect the CPU fan to the CPU fan connector
(CPU_FAN1).
NOTE: Though AM2CPU Board provides 4-Pin CPU fan (Quiet Fan) support, the 3-Pin CPU fan still can work
successfully even without the fan speed control function. If you use a 4-Pin CPU fan on AM2CPU
Board, the fan speed control function needs to depend on the motherboard support.
STEP 2: Install DRAM into AM2CPU Board.
STEP 3: If necessary, remove the CPU heatsink retention module from the ASRock motherboard
that you are going to install AM2CPU Board into.
NOTE: Whether or not to remove the CPU heatsink retention module from the ASRock motherboard depends
on the type of CPU fan installed on AM2CPU Board.
STEP 3-1: Place the ASRock motherboard with its backside up.
STEP 3-2: Use a flathead screwdriver to press down the WHITE fastener of the CPU
heatsink retention module through the hole. Repeat with remaining fasteners.
STEP 3-3: Use a pair of pliers to clutch the BLACK supporting part of the CPU heatsink
retention module, then press it down through the hole. Repeat with remaining
supporting parts.
STEP 3-4: Place the ASRock motherboard with its backside down, then remove the
loosened CPU heatsink retention module from the motherboard.
STEP 4: Adjust the jumper settings on ASRock motherboard to fit with the requirement for AMD
940-pin AM2 CPU installation. (See ASRock Motherboard User Manual for details).
STEP 5: Secure ASRock motherboard to the chassis.
STEP 6: Install AM2CPU Board into the Future CPU Port (a yellow slot) on ASRock motherboards
that support future CPU upgrade function by aligning the golden finger of AM2CPU
Board with the Future CPU Port.
NOTE: If you install AM2CPU Board and plan to install the AGP VGA card / PCI Express VGA card to the AGP
slot / PCI Express slot nearby Future CPU Port, please do not choose the VGA card with the heatsink
which is too thick to collide with AM2CPU Board. Otherwise, it may cause permanent damage to both
your AM2CPU Board and VGA card!
STEP 7: Secure AM2CPU Board with the bracket to the chassis.
STEP 8: Ensure to connect the power supply withATX 12V plug to theATX 12V Power Connector
(ATX12V1) on AM2CPU Board. Failing to do so will cause power up failure.

Please download the latest BIOS version of your motherboard from
our website and install it to your system; otherwise, your motherboard
may not support AM2CPU Board upgrade function. For the latest
