AIMB-253 Mainboard Quick Components Guide 2-2
Hardware Setup CPU (Central Processing Unit) The mainboard supports Intel® Core 2 Duo/Core Duo/Core Solo processors. When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating. If you do not have the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer. Important 1. Overheating will seriously damage the CPU and system.
AIMB-253 Mainboard CPU & Cooler Set Installation 1. Place the CPU on top of the socket. Make sure to align the gold arrow on the CPU with the arrow key on the socket. 2. Push the CPU down until its pins securely fit into the socket. 3. On the front end of the CPU socket is a locking mechanism designed into the form of a screw. Make sure that you actuate or deactuate this mechanism with a screwdriver before and after installing the CPU. 4. Release the metal clips on the retention mechanism.
Hardware Setup 5. Mount the cooler set (fan & heatsink bundled) on top of the CPU and fit it into the retention mechanism. 6. Secure the metal clips back to the retention mechanism. 7. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on the mainboard.
AIMB-253 Mainboard Memory The mainboard provides one 240-pin non-ECC DDRII 533/667 DIMM slot and supports up to 2GB system memory. DDRII 240-pin, 1.8V 64x2=128 pin 56x2=112 pin Single-Channel: All DIMMs in GREEN Installing DDRII Modules 1. The memory module has only one notch on the center and will only fit in the right orientation. 2. Insert the memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the DIMM slot.
Hardware Setup Power Supply ATX 20-Pin System Power Connector: ATX1 This connector allows you to connect to an ATX power supply. To connect to the ATX power supply, make sure the plug of the power supply is inserted in the proper orientation and the pins are aligned. Then push down the power supply firmly into the connector.

AIMB-253 Mainboard Back Panel Serial Port Connector The serial port is a 16550A high speed communications port that sends/ receives 16 bytes FIFOs. You can attach a serial mouse or other serial devices directly to the connector. VGA Connector The DB15-pin female connector is provided for VGA monitors. Mouse/Keyboard Connector The standard PS/2® mouse/keyboard DIN connector is for a PS/2® mouse/keyboard.
Hardware Setup Connectors Chassis Intrusion Switch Connector: JCI1 This connector connects to a 2-pin chassis switch. If the chassis is opened, the switch will be short. The system will record this status and show a warning message on the screen. To clear the warning, you must enter the BIOS utility and clear the record.
AIMB-253 Mainboard Serial ATA Connectors: SATA1, SATA2 SATA1~SATA2 are high-speed SATA interface ports and support SATA data rates of 150MB/s. Each SATA connector can connect to 1 hard disk device and is fully compliant with Serial ATA 1.0 specifications. SATA1 SATA2 Serial ATA cable Take out the dust cover and connect to the hard disk devices Connect to SATA1/2 Important Please do not fold the Serial ATA cable into 90-degree angle. Otherwise, data loss may occur during transmission.
Hardware Setup Audio Amplifier Connector: JAMP1 The JAMP1 is used to connect audio amplifiers to enhance audio performance. Pin Definition JAMP1 1 PIN SIGNAL 1 AMP_L- 2 3 4 AMP_L+ AMP_RAMP_R+ Front Audio Connector: JAUD1 The JAUD1 connects to an optional audio bracket that provides extra front panel audio IO jacks.
AIMB-253 Mainboard Fan Power Connectors: CPUFAN1, SYSFAN1 The fan power connectors support system cooling fan with +12V. When connecting the wire to the connectors, always take note that the red wire is the positive and should be connected to the +12V, the black wire is Ground and should be connected to GND. If the mainboard has a System Hardware Monitor chipset on-board, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control.
