MANO831 Mini ITX Board Chapter 3 Hardware Installation Take note of the following precautions before you install motherboard components or change any motherboard settings. Caution 3.1 Unplug the power cord from the wall socket before touching any component. Use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity.
MANO831 Mini ITX Board Place this side towards the rear of the chassis. 3.2 Central Processing Unit (CPU) ® The motherboard comes with onboard Intel Atom™ D2550 processor. 3.2.1 CPU Location Locate the CPU on the motherboard.
MANO831 Mini ITX Board 3.2.2 The CPU Heatsink and Fan ® Intel Atom™ processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. CPU FAN 1 Caution Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside the system may damage the motherboard components. These are not jumpers! DO NOT place jumper caps on the fan connectors.
MANO831 Mini ITX Board 3.3 System Memory 3.3.1 Overview The motherboard comes with two 204-pin Double Data Rate 3 (DDR3) Small Outline Dual Inline Memory Modules (SO-DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR SO-DIMM but has a 204-pin footprint compared to the 204-pin DDR2 DIMM. DDR3 SO-DIMM is notched differently to prevent installation on a DDR2 SO-DIMM socket.
MANO831 Mini ITX Board 3.3.2 Memory Configurations You may install 1GB and 2GB unbuffered non-ECC DDR3 SO-DIMMs into the SO-DIMM sockets using the memory configurations in this section. Important 3.3.3 1. IF you installed two 2GB memory modules, the system may detect less than 3GB of total memory because of address space allocation for other critical functions. This limitation applies to Windows XP 32-bit version operating system since it does not support PAE (Physical Address Extension) mode.
MANO831 Mini ITX Board 2. Firmly insert the SO-DIMM into the socket until the retaining clips snap back in place and the SO-DIMM is properly seated. Retaining clip Important Caution 26 DDR3 SO-DIMM notch A DDR3 SO-DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a SO-DIMM into a socket to avoid damaging the SO-DIMM. The DDR3 SO-DIMM sockets do not support DDR2 SO-DIMMs. DO NOT install DDR2 SO-DIMM to the DDR3 SO-DIMM socket.
MANO831 Mini ITX Board 3.3.4 1. 2. Removing a SO-DIMM Simultaneously press the retaining clips downward to unlock the SO-DIMM. Remove the SO-DIMM from the socket. Retaining clip Note 3.4 DDR3 SO-DIMM notch Support the SO-DIMM lightly with your fingers when pressing the retaining clips. The SO-DIMM might get damaged when it flips out with extra force. Expansion Card In the future, you may need to install expansion cards.
MANO831 Mini ITX Board 3.4.2 Configuring an Expansion Card After installing the expansion card, configure it by adjusting the software settings. 1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 5 for information on BIOS setup. 2. Assign an IRQ to the card if needed. 3. Install the software drivers for the expansion card. 3.4.3 PCI Slot This motherboard supports one PCI slot that complies with the PCI specifications.
MANO831 Mini ITX Board 3.4.5 CompactFlashTM Socket TM This motherboard supports one CompactFlash card socket and its location is on TM bottom side of the PCB. The following figure shows a CompactFlash card installed on TM the CompactFlash socket.
