Chapter 2 Installation Chapter 2 Installation G41M-PS is a Micro ATX form factor (9.6" x 7.5", 24.4 x 19.1 cm) motherboard. Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it.
2.3 CPU Installation 2.3 CPU Installation 2.3 CPU Installation 2.3 CPU Installation 2.3 CPU Installation For the installation of Intel 775-LAND CPU, please follow the steps below. 775-Pin Socket Overview Before you insert the 775-LAND CPU into the socket, please check if the CPU surface is unclean or if there is any bent pin on the socket.
Page 15
For proper inserting, please ensure to match the two orientation key notches of the CPU with the two alignment keys of the socket. Step 2-3. Carefully place the CPU into the socket by using a purely vertical motion. Step 2-4. Verify that the CPU is within the socket and properly mated to the orient keys.
Installation of CPU Fan and Heatsink Installation of CPU Fan and Heatsink Installation of CPU Fan and Heatsink Installation of CPU Fan and Heatsink Installation of CPU Fan and Heatsink This motherboard is equipped with 775-Pin socket that supports Intel 775-LAND CPU. Please adopt the type of heatsink and cooling fan compliant with Intel 775-LAND CPU to dissipate heat.
Modules (DIMM) y Modules (DIMM) G41M-PS motherboard provides two 240-pin DDR3 (Double Data Rate 3) DIMM slots, and supports Dual Channel Memory Technology. For dual channel configuration, you always need to install two identical (the same brand, speed, size and chip-type) memory modules in the DDR3 DIMM slots to activate Dual Channel Memory Technology.
EUP_LAN1 Note: EUP_LAN and EUP_AUDIO jumper design decreases the power consumption of this motherboard to meet EuP standard. With an ASRock EuP ready motherboard and a power supply that the 5VSB power efficiency is higher than 50% under 100mA current consumption, your system is able to submit EuP standard. The default setting (short pin2 and pin3) is EuP disabled.
