Chapter 1 Product introduction 1.1 Welcome! Thank you for buying an ASUS® P5P41TD motherboard! The motherboard delivers a host of new features and latest technologies, making it another standout in the long line of ASUS quality motherboards! Before you start installing the motherboard, and 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.
Intel® G41 Chipset The Intel® G41 Express Chipset is designed to support dual-channel DDR3 1333 (overclocking)/1066/800 architecture, 1333/1066/800 Front Side Bus (FSB), PCIe 1.1, and mutli-core CPUs. It especially includes Intel® Fast memory bandwidth and reduces the latency of the memory accesses. Dual channel DDR3 1333 (O.C.)/1066/800 support This motherboard supports DDR3 memory that features data transfer rates of 1333 (O.C.
ASUS Express Gate Express Gate is an ASUS exclusive OS, which lets you instantly access the Internet and key applications before entering the Windows® OS. • ASUS Express Gate supports installation on SATA HDDs, USB HDDs and flash drives with at least 1.2GB free disk space. When installing it on USB HDDs or flash drives, connect the drives to the motherboard USB port before turning on the computer. • The actual boot time depends on the system configuration.
1.4 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings. • Unplug the power cord from the wall socket before touching any component. • Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity. • Hold components by the edges to avoid touching the ICs on them.
1.5 Motherboard overview Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Ensure that you 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 1.5.2 Screw holes When installing the motherboard, ensure that you place it into the chassis in the correct orientation.

6. Apply some Thermal Interface Material to the exposed area of the CPU that the heatsink will be in contact with, ensuring that it is spread in an even thin layer. Some heatsinks come with pre-applied thermal paste. If so, skip this step. DO NOT eat the Thermal Interface Material. If it gets into your eyes or touches your skin, ensure that you wash it off immediately, and seek professional medical help. To prevent contaminating the paste, DO NOT spread the paste with your finger directly. 7.
1.6.2 Installing the CPU heatsink and fan The Intel® LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. • When you buy a boxed Intel® processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, ensure that you use only Intel®‑certified multi‑directional heatsink and fan. • Your Intel® LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install.
3. 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 P5P41TD P5P41TD 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.
4. Carefully remove the heatsink and fan assembly from the motherboard. 5. Rotate each fastener clockwise to ensure correct orientation when reinstalling. 1.7 System memory 1.7.1 Overview DIMM_B1 DIMM_B2 DIMM_A1 DIMM_A2 The motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules (DIMM) sockets.
1.7.2 Memory configurations You may install 512MB, 1GB, and 2GB unbuffered non‑ECC DDR3 DIMMs into the DIMM sockets. • You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • Always install DIMMs with the same CAS latency.
