ASUS P5QL-EM Motherboard Specification

The ASUS P5QL-EM is a robust micro-ATX motherboard designed to accommodate Intel processors with an LGA 775 socket, supporting Intel Core 2 Quad, Core 2 Duo, Pentium, and Celeron CPUs. It is built on the Intel G43 Express chipset, which integrates the Intel Graphics Media Accelerator X4500 for high-quality onboard graphics performance. The motherboard supports up to 16GB of dual-channel DDR2 memory across four DIMM slots, with speeds up to 1066MHz through overclocking. For expansion, it features a PCIe 2.0 x16 slot for discrete graphics cards, a PCIe x1 slot, and two PCI slots for additional peripherals.

Storage options include six SATA 3Gb/s ports, offering RAID 0, 1, 5, and 10 configurations for enhanced data security and performance. Connectivity is facilitated by a Gigabit LAN port for high-speed internet access and eight USB 2.0 ports, providing ample options for peripheral connections. The onboard Realtek ALC1200 audio codec supports 8-channel high-definition audio, delivering superior sound quality. Additionally, the motherboard supports ASUS's Express Gate technology, allowing users to access the internet and key applications without a full system boot.

The ASUS P5QL-EM is equipped with a DVI-D and VGA port for video output, accommodating dual-monitor setups. It includes ASUS's proprietary EPU (Energy Processing Unit) for efficient energy management and ASUS CrashFree BIOS 3 and EZ Flash 2 for easy system recovery and BIOS management. This motherboard is suitable for users seeking a balance of performance and efficiency, ideal for both home and office applications.

ASUS P5QL-EM Motherboard F.A.Q.

How do I reset the BIOS settings on my ASUS P5QL-EM motherboard?

To reset the BIOS on your ASUS P5QL-EM, power off the computer and unplug it. Open the case and locate the CMOS jumper near the battery on the motherboard. Move the jumper from the default position (usually covering pins 1 and 2) to the reset position (covering pins 2 and 3) for about 10 seconds, then move it back. Alternatively, you can remove the CMOS battery for a few minutes and reinsert it.

What is the maximum RAM capacity supported by the ASUS P5QL-EM motherboard?

The ASUS P5QL-EM motherboard supports up to 16GB of DDR2 RAM across its four DIMM slots, with each slot supporting up to 4GB of memory.

How can I update the BIOS on my ASUS P5QL-EM motherboard?

To update the BIOS, download the latest BIOS file from the ASUS support website. Copy the file to a USB drive formatted with FAT32. Restart your computer and enter the BIOS setup by pressing the 'Delete' key during boot. Navigate to the 'Tools' menu and use the ASUS EZ Flash utility to select the BIOS file from your USB drive and update it.

Why is my ASUS P5QL-EM motherboard not detecting my hard drive?

Ensure that the SATA cable is securely connected to both the hard drive and the motherboard. Check the BIOS settings to verify that the SATA ports are enabled. If the hard drive is still not detected, try connecting it to a different SATA port or test with another SATA cable.

What processors are compatible with the ASUS P5QL-EM motherboard?

The ASUS P5QL-EM motherboard supports Intel processors in the LGA 775 package, including the Intel Core 2 Quad, Core 2 Duo, Pentium Dual-Core, and Celeron series. Ensure your processor is listed in the compatibility section of the motherboard's manual.

How can I improve the cooling efficiency of my ASUS P5QL-EM motherboard?

To improve cooling, ensure that your case has adequate airflow by organizing cables and adding additional case fans if needed. Apply a high-quality thermal paste between the CPU and its cooler, and consider upgrading to a more efficient CPU cooler. Regularly clean dust from all fans and heatsinks.

What should I do if my ASUS P5QL-EM motherboard fails to boot?

First, check all power connections and ensure the power supply is working. Verify that the RAM and CPU are properly seated. Remove any unnecessary hardware to isolate the issue. If the problem persists, reset the BIOS and test with a different power supply or RAM module.

Can the ASUS P5QL-EM motherboard support a graphics card upgrade?

Yes, the ASUS P5QL-EM has a PCIe x16 slot for a discrete graphics card. Ensure your power supply can provide sufficient power for the upgraded graphics card, and check for physical space within the case to accommodate the card.

How do I enable virtualization on my ASUS P5QL-EM motherboard?

To enable virtualization, enter the BIOS setup by pressing the 'Delete' key during boot. Navigate to the 'Advanced' tab and select 'CPU Configuration.' Enable 'Intel Virtualization Technology,' then save and exit the BIOS setup.

What are the integrated audio features of the ASUS P5QL-EM motherboard?

The ASUS P5QL-EM motherboard features integrated 8-channel High Definition Audio, with support for jack-sensing, multi-streaming, and front panel jack-retasking. It uses the Realtek ALC1200 audio codec.
