Chapter 1 Product introduction Thank you for buying an ASUS® P5G41-M SI motherboard! Before you start installing the motherboard, and hardware devices on it, check the items in your motherboard package. Refer to page ix for the list of accessories. If any of the items is damaged or missing, contact your retailer. 1.1 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings.
1.2 Motherboard overview 1.2.1 Motherboard layout Ensure that you install the motherboard into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis. 1 2 3 4 5 6 7 4 24.4cm(9.6in) CPU_FAN KBPWR KBMS ATX12V COM1 RTL 8112L 3 EATXPWR TPM Intel® G41 LAN1_USB12 24.4cm(9.
1.3 Central Processing Unit (CPU) This motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™ 2 Quad / Core™2 Exreme / Core™2 Duo / Pentium® dual-core / Celeron® dual-core / Celeron® processors. Ensure that all power cables are unplugged before installing the CPU. • Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the socket contacts are not bent.
1.4.2 Memory configurations You may install a 512MB, 1GB, and 2GB unbuffered non-ECC DDR2 DIMM into the DIMM socket. • 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.

1.5.2 Configuring an expansion card After installing the expansion card, configure it by adjusting the software settings. 1. 2. 3. Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for information on BIOS setup. Assign an IRQ to the card. Install the software drivers for the expansion card.
• If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery. • You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature. Shut down and cut off the AC power, then reboot the system, the BIOS automatically resets parameter settings to default values. 2.
