1.1 Welcome! Thank you for buying the RX945G motherboard! The motherboard delivers a host of new features and latest technologies, making it another standout in the long line of quality motherboards! Before you start installing the motherboard and any hardware devices on it, check the items in your package with the list below. 1.2 Package contents Check your motherboard package for the following items.
Dual-core processors contain two physical CPU cores with dedicated L2 caches to meet demands for more powerful processing. Intel®’s 65nm process is the most advanced chip manufacturing technology, delivering breakthrough performance, enhanced media experience, and low power consumption. Intel® 65nm dual-core processors utilize the latest package technologies for a thinner, lighter design without compromising performance.
PCI Express™ interface The motherboard fully supports PCI Express, the latest I/O interconnect technology that speeds up the PCI bus. PCI Express features point‑to‑point serial interconnections between devices and allows higher clockspeeds by carrying data in packets. This high speed interface is software compatible with existing PCI specifications. See page 1-22 for details.
1.5 Motherboard overview Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components. 1.5.1 Placement direction When installing the motherboard, make sure that you place it into the chassis in the correct orientation.
1.5.
1.6 Central Processing Unit (CPU) The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Duo / Pentium® D / Pentium® 4 / Celeron® processor in the 775-land package. 1.6.1 • Your boxed Intel® Pentium® 4 LGA775 processor package should come with installation instructions for the CPU, fan and heatsink assembly. If the instructions in this section do not match the CPU documentation, follow the latter.
2. Press the load lever with your thumb (A) and move it to the left (B) until it is released from the retention tab. Retention tab PnP Cap A Load lever B This side of the cam box should face you. To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU. 3. Lift the load lever in the direction of the arrow to a 135º angle. 4. Lift the load plate with your thumb and forefinger to a 100º angle (A), then push the PnP cap from the load plate window to remove (B).
6. Close the load plate (A), then push the load lever (B) until it snaps into the retention tab. A B The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU! The motherboard supports Intel® Core™2 Duo / Pentium® D / Pentium® 4 / Celeron® LGA775 processors with the Intel® Enhanced Memory 64 Technology (EM64T), Enhanced Intel SpeedStep ® Technology (EIST), and Hyper‑Threading Technology.
1.6.2 Installing the CPU heatsink and fan ® The Intel Core™2 Duo / Pentium® D / Pentium® 4 / Celeron® LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. • Install the motherboard to the chassis before you install the CPU fan and heatsink assembly • When you buy a boxed Intel® Pentium® 4 processor, the package includes the CPU fan and heatsink assembly.
2. 3. Push down two fasteners at a time in a diagonal sequence to secure the heatsink and fan assembly in place. A B B A B A A B When the fan and heatsink assembly is in place, connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN. CPU_FAN CPU FAN PWM CPU FAN IN CPU FAN PWR GND CPU fan connector Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector.
1.6.3 Uninstalling the CPU heatsink and fan To uninstall the CPU heatsink and fan: 1. Disconnect the CPU fan cable from the connector on the motherboard. 2. Rotate each fastener counterclockwise. 3. Pull up two fasteners at a time in a diagonal sequence to disengage the heatsink and fan assembly from the motherboard.
4. Remove the heatsink and fan assembly from the motherboard. 5. Rotate each fastener clockwise to reset the orientation. Narrow end of the groove The narrow end of the groove should point outward after resetting. (The photo shows the groove shaded for emphasis.
1.7 System memory 1.7.1 Overview The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets. A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to prevent installation on a DDR DIMM socket.
1.7.3 • Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. Refer to the memory Qualified Vendors List on the next page for details. • Due to CPU limitation, DIMM modules with 128 Mb memory chips or doublesided x16 memory chips are not supported in this motherboard. DDR2 Qualified Vendors List The following table lists the memory modules that have been tested and qualified for use with this motherboard.
