The ASUS P9X79 WS highlights the utility and power of multi-GPU designs, featuring 4-Way SLI™ at 100% greater graphics performance than 2-Way SLI™. Similarly, its dual Intel® LAN design increases online output and lowers CPU utilization by up to 71%. Three times faster SSD Caching boosts system performance while the new board also comes with complete compatibility with a wide range of CPUs, memory, operating systems, graphics card types and RAID varieties. Exclusive ASUS USB BIOS Flashback makes modifying the BIOS easier, ideal for overclocking and troubleshooting. ASUS is also offering its new ARS warranty support* with this board.

Best performance for 4-Way SLI™ and quad CrossFireX™
Based on extensive benchmarking, the 4-Way SLI™ offered by the P9X79 WS works up to 30% faster than standard 3-Way SLI™ and up to 100% faster compared to 2-Way SLI™, giving professional and power users more graphics performance on demand. Using PCI Express 3.0 x16 links, the four GPUs can reach their full potential, perfect for both intense gaming and commercial uses such as mechanical and architectural design, interior design, aeronautics, plus audio and video production. As there are six total PCIe slots, that leaves two additional slots should any extra peripheral cards be needed.

Dual Intel® hardware-accelerated LAN
The inclusion of two Intel® hardware LAN ports reduces system load while working online, which helps ensure the fastest possible connections as well as CPU utilization up to 71% lower than standard Gigabit LAN. Dual hardware Intel® LAN reduces packet loss and connection latency, while offering improved operating system support and compatibility.

Compatible with multiple CPU and memory types
To guarantee effective integration into as many usage scenarios as possible, the P9X79 WS works with both 2nd generation Intel® Core™ i7 processors and the workstation-specific Intel® Xeon® family of CPUs. Additionally, it is compatible with both mainstream non-ECC memory, and highly reliable ECC (error-correcting) RAM, which is more suitable to professional workstation applications.

Three times faster performance with one-click ASUS SSD Caching
Working up to three times faster than a standard mechanical hard drive, SSD Caching boosts overall system performance via the use of an installed SSD as a cache for frequently accessed data. SSD Caching can be turned on and off in one click, with no system restart.

Setting a new standard of complete multi-faceted compatibility
Aiming the P9X79 WS at diverse users, ASUS has engineered the product to cover as many operating systems as possible, ensuring smooth compatibility. It also works with every major graphics card vendor on the market, as well as a full range of RAID cards, capture cards and LAN cards. This means a broad spectrum of users, from system integrators and gamers to professionals, can rely on the P9X79 WS for their flexible expandability and upgrading needs, all hassle-free.

USB BIOS Flashback, extreme expandability, and new ARS
Exclusive to ASUS boards, BIOS Flashback can flash the BIOS with just one click, with no further boot-up needed. Also, the P9X79 WS ships with eight DIMM slots for up to 64GB quad-channel DDR3 RAM to provide more capacity. An onboard three-colored LED indicates the board’s overclocking status. Red means overclocked, blue indicates normal settings, and green denotes power saving mode. New ASUS Advanced Replacement Service* (ARS) reduces RMA lead times and offers more convenient returns and product replacement in the event of any defects.

*ARS service currently available in select Eurozone markets. ASUS plans to expand this offering to other markets in due course.
