Safety information

Electrical safety
To prevent electric shock hazard, disconnect the power cable from the electric outlet before relocating the system. When adding or removing devices to or from the system, ensure that the power cables for the devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device. Before connecting or removing signal cables from the motherboard, ensure that all power cables are unplugged. Seek professional assistance before using an adpater or extension cord. These devices could interrupt the grounding circuit. Make sure that your power supply is set to the correct voltage in your area. If you are not sure about the voltage of the electrical outlet you are using, contact your local power company. If the power supply is broken, do not try to fix it by yourself. Contact a qualified service technician or your retailer. Before installing the motherboard and adding devices on it, carefully read all the manuals that came with the package. Before using the product, make sure all cables are correctly connected and the power cables are not damaged. If you detect any damage, contact your dealer immediately. To avoid short circuits, keep paper clips, screws, and staples away from connectors, slots, sockets and circuitry. Avoid dust, humidity, and temperature extremes. Do not place the product in any area where it may become wet. Place the product on a stable surface. If you encounter technical problems with the product, contact a qualified service technician or your retailer.

ASUS Crystal Sound

This feature can enhance speech-centric applications like Skype, online game, video conference and recording. Noise Filter This feature detects repetitive and stationary noises (non-voice signals) like computer fans, air conditioners, and other background noises then eliminates it in the incoming audio stream while recording.

ASUS EZ DIY

ASUS EZ DIY feature collection provides you with easy ways to install computer components, update the BIOS or back up your favorite settings. ASUS O.C. Profile The motherboard features the ASUS O.C. Profile that allows users to conveniently store or load multiple BIOS settings. The BIOS settings can be stored in the CMOS or a separate file, giving users freedom to share and distribute their favorite overclocking settings. See page 2-25 for details. ASUS CrashFree BIOS 3 The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a bootable floppy disk, USB flash disk, or the motherboard Support DVD containing the original BIOS file. See page 2-6 for details. ASUS EZ Flash 2 EZ Flash 2 is a user-friendly BIOS update utility. Simply launch this tool and update BIOS from a USB flash disk before entering the OS. You can update your BIOS only in a few clicks without preparing a bootable floppy disk or using an OS-based utility. See pages 2-3 and 2-24 for details.

ASUS Stylish features

ASUS MyLogo2
This feature allows you to convert your favorite photo into a 256-color boot logo for a more colorful and vivid image on your screen. See page 2-22 for details.

AI Booster

ASUS Intelligent Overclocking features
The ASUS AI Booster allows you to overclock the CPU speed in Windows environment without the hassle of booting the BIOS.

Precision Tweaker

This feature allows you to fine-tune the CPU/memory voltage and gradually increase the memory, FSB, and PCI Express frequency at 1MHz increment to achieve maximum system performance. See page 2-12 to 2-17 for details.
CPU Parameter Recall (C.P.R.)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the BIOS default settings in case the system hangs due to overclocking failure. When the system hangs due to overclocking failure, C.P.R. eliminates the need to open the system chassis and clear the RTC data. Simply shut down and reboot the system, and the BIOS automatically restores the CPU default settings for each parameter.

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. 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. Hold components by the edges to avoid touching the ICs on them. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component. Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets. The figure illustrates the location of the DDR2 DIMM sockets:

DIMM_B1 DIMM_B2

P5Q SE2 240-pin DDR2 DIMM sockets
Channel Channel A Channel B Sockets DIMM_A1 and DIMM_A2 DIMM_B1 and DIMM_B2

DIMM_A1 DIMM_A2

You may install 512MB, 1GB, 2GB, and 4GB unbuffered nonECC DDR2 DIMMs into the DIMM sockets. Recommended Memory Configurations
Mode Populated Populated Populated Sockets DIMM_A1 Populated DIMM_A2 DIMM_B1 Populated Populated Populated Populated DIMM_B2

Memory configurations

Single-Channel Dual-channel (1) Dual-channel (2)
When using only one DDR2 DIMM, start installing it from DIMM_A1 or DIMM_B1 for better overclocking capability. For dual-channel configuration (1), install two identical DIMMs in DIMM_A1 and DIMM_B1. For dual-channel configuration (2), you can: - install four identical DIMMs in all four slots; or
- install one identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow slots) and another identical DIMM pair in DIMM_A2 and DIMM_B2 (black slots). Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. When you install a total memory of 4GB or more, Windows 32-bit operating system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended if you are using a Windows 32-bit operating system. This motherboard does not support memory modules made up of 128Mb chips. This motherboard supports up to 16GB on a Windows XP Professional x64 and Windows Vista x64 Edition. You may install a maximum of 4GB DIMM on each slot. The default memory operation frequency is dependent on its SPD. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. To operate at the vendor-marked or at a higher frequency, see section 2.4 Ai Tweaker menu for manual memory frequency adjustment. The memory modules may require a better cooling system to work stably under full loading (4 DIMMs) or overclocking setting. Some old-version DDR2-800 DIMMs may not match Intels OnDieTermination (ODT) requirement and will automatically downgrade to run at DDR2-667. If this happens, contact your memory vendor to check the ODT value. Due to chipset limitation, DDR2-800 with CL=4 will be downgraded to run at DDR2-667 by default setting. If you want to operate with lower latency, adjust the memory timing manually.
