Advanced Thermal Design ASUS has devoted special efforts to address the thermal issues across the motherboard, and most notably the areas that reside the CPU, power, Northbridge and Southbridge. Stack Cool 2 Stack Cool 2 is a fan-less and zero-noise cooling solution offered exclusively by ASUS. It effectively transfers heat generated by the critical components to the other side of the specially designed PCB (printed circuit board) for effective heat dissipation. 8 Phase Power Design ASUS 8-Phase Power Design keeps CPU and power module away from suffering risk of high power stress, which makes CPU lifetime much longer and system more stable. Furthermore, It provides high efficiency operation to generate less heat than conventional power solutions and consequently achieve cool system environment. With this strong power pump, this motherboard is made for overclocking. Fanless Design: Heat-pipe Thermal solution Cooling fans, though a popular thermal solution, also come with noise and malfunction likelihood. ASUS Motherboard's fanless concept is specifically created to provide a cool environment without all the baggage. The heat pipe, heat sinks and strategic board layout were tailor made to dissipate heat in the most efficient manner.

AI Clock Skew AI Clock Skew automatically skews the memory clock signal timing, thus improving memory overclocking capability by 10 to 15%, depending on the memory features when users overclock memory frequency. Users can easily enjoy better memory overclocking without strenuously fine-tuning the clock signal timing. For professional users, they can still adjust each memory channel's clock signal separately to reach the highest memory frequency.

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.

Precision Tweaker It offers ways to raise system performance inch-by-inch and step-by-step to achieve maximum performance! This is about getting the most out of your machine and taking pride in your customized computer.

AI NOS™ Applications such as 3D games and video editing demand a huge chunk of system resource. Inject "nitrous oxide" into your CPU! The patented AI NOS™ (Non-delay Overclocking System) technology intelligently detects system load and automatically boosts performance for the most demanding tasks. Unlike other dynamic overclocking techniques, AI NOS™ reacts much faster to satisfy your unending need for speeds.

PEG Link This latest technology, PEG (PCI Express Graphics) Link Mode, is a unique feature that enables users to boost graphics card performance for superior video quality. PEG Link allows users to raise GPU and VGA memory throughput via the motherboard BIOS the same way system bus and memory bus are tweaked. PEG Link Mode enables powerful video performance on DX8 and DX9 applications. ASUS engineers carefully fine-tuned the parameters for every single PCI-Express card to provide system stability during high-speed graphics operation.

AI Gear To balance both system performance and quietness, AI Gear allows users to choose from profiles to adjust CPU frequency and vCore voltage, minimizing system noise and power consumption. Users can real-time change the mode under operating system to suit their needs.

AI Nap With AI Nap, users can instantly snooze your PC without terminating the tasks. System will continue operating at minimum power and noise when user is temporarily away. It keeps downloading files or running applications in quietest state while you're sleeping. Simply click keyboard or mouse, you can swiftly wake up the system in few seconds.

ASUS MyLogo2 The ASUS MyLogo2 is the new feature present in the motherboard that allows you to personalize and add style to your system with customizable and animated boot logos.

PCI Express Architecture PCI Express is the latest I/O interconnect technology that will replace the existing PCI. With a bus bandwidth 4 times higher than that of AGP 8X interface, PCI Express x16 bus performs much better than AGP 8X in applications such as 3D gaming. PCI Express x1 also outperforms PCI interface with its exceptional high bandwidth up to 500MB/s. The high speed PCI Express interface creates new usages on desktop PCs e.g., Gigabit LAN, 1394b, and high-speed RAID systems. Dual Gigabit LAN The integrated dual Gigabit LAN design allows a PC to serve as a network gateway for managing traffic between two separate networks. This capability ensures rapid transfer of data from WAN to LAN without any added arbitration or latency.

High Definition Audio Enjoy high-end sound system on your PC! The onboard 8-channel HD audio (High Definition Audio, previously codenamed Azalia) CODEC enables high-quality 192KHz/24-bit audio output, jack-sensing feature, retasking functions and multi-streaming technology that simultaneously sends different audio streams to different destinations. You can now talk to your partners on the headphone while playing a multi-channel network games. All of these are done on one computer.

SATA on the Go The P5W64 WS Professional supports the next-generation hard drives based on the Serial ATA (SATA) 3Gb/s storage specification, delivering enhanced scalability and doubling the bus bandwidth for high-speed data retrieval and saves.
