NVIDIA SLI™ Technology
NVIDIA SLI™ (Scalable Link Interface) takes advantage of the increased bandwidth of the PCI Express bus architecture and features intelligent hardware and software that allows two GPUs to efficiently work together to deliver earth-shattering, scalable performance. For some applications nearly 2X performance! (From www.NVIDIA.com)

Dual-Channel DDR2-800
DDR2 is the next generation memory technology to replace the current DDR. With the highest speed up to 800MHz,DDR2 memory provides great performance for 3D graphics and other memory demanding applications.

ASUS EPU
Enables the Most Energy Efficient Motherboard in the World
The ASUS EPU utilizes innovative technology to digitally monitor and finetune the CPU power supply with improved VR responses in heavy or light loadings.

Working together with AI Gear 3, it automatically provides power for higher performance or improves efficiency by 50% when the PC is running low intensity applications - helping you attain the best possible power efficiency and energy savings of up to 80.23% to help save the environment.

Fanless Design
Provide a cool environment without all the baggage
Cooling fans, though a popular thermal solution, also come with noise and malfunction likelyhood. ASUS Motherboard´s fansless concept is specifically created to provide a cool environment without all the baggage.

ASUS has devoted special efforts to address the thermal issues across the motherboard, and most notably the areas that reside the CPU, power, VGA, and chipsets. The heat sinks were tailor made to dissipate heat in the most efficient manner.

Q-Fan 2
Adjusts both CPU fan and chassis fan speeds according to system loading
ASUS Q-Fan2 technology intelligently adjusts both CPU fan and chassis fan speeds according to system loading to ensure quiet, cool and efficient operation.

Optional Fan (for Water-Cooling or Passive-Cooling only)
Maximize Water-Cooling or Passive-Cooling performance!
The optional fan is specifically designed to provide sufficient airflow over the chipset area and CPU power modules when water-cooling or passive-cooling is utilized, ensuring effective heat dissipation for the entire system.

Uses 100% All High-quality Conductive Polymer Capacitors!
This motherboard uses all high-quality conductive polymer capacitors onboard for durability, improved lifespan, and enhanced thermal capacity.
