12K hour caps - Capacitors with World's Best Longevity

ASUS is the world's first motherboard manufacturer to introduce 12K solid capacitors, and X99-E WS/USB 3.1 is of course equipped. These Japanese-made capacitors are the most durable in the industry, able to endure up to 12K hours at 105 °C and 1.2M hours at 65 °C. This is far higher than the temperatures generated by everyday computing, so X99-E WS/USB 3.1 is built for endurance . Our 12k capacitors also boast lowered equivalent series resistance (ESR) for increased efficiency and minimized heat generation improving overall performance!

Q-Code Logger one-touch status checker

Q-code logger is your one-touch status checker that lets users easily check system status at any time. Plug a flash drive into adjacent USB port, press the motherboard's dedicated Q-Code logger button and all ASUS Q-Code event logs for the current live session will be copied to the drive even with the system off.

ASUS Dr. Power hassle-free power supply health monitoring

As the X99-E WS/USB 3.1 is meant for professional users who rely on non-stop operation, stable power delivery is critical. Real time power supply health detection helps prevent sudden system shutdown and provides hassle-free notifications should power delivery be insufficient. Additionally, LED messages on the board clearly indicate any relevant power issues in the event your system fails to boot.

Drive 8-core CPU and DDR4 performance beyond all expectations!

The X99-E WS/USB 3.1' CPU socket includes extra pins that connect proprietary circuitry to extra contacts found on Haswell-E's land grid array (LGA). When combined with our customized UEFI, this exclusive feature offers comprehensively-improved overclocking margins, especially under extreme liquid-nitrogen (LN2) overclocking. You'll enjoy better margins for memory overclocking, better comparative memory performance under the same frequencies, and better margins for CPU overclocking with minimal voltage drop so you're able to push the latest processors and DDR4 memory beyond their limits! OC Socket is 100% compatible with the new Haswell-E LGA 2011-3 processors. Forget limits, break every performance barrier with OC Socket!

Make your memory go faster

This is the first platform to support DDR4 memory, and it is capable of overclocking memory up to DDR4 3200+ MHz with all eight DIMMs fully loaded! ASUS-exclusive T-Topology circuit design plus patent-pending OC Socket unleash the full potential of DDR4 by minimizing crosstalk and signal reflections. Thanks to our expertise in motherboard layout design, signal timing issues are also greatly reduced, resulting in improved stability and overall performance. ASUS works with almost every DDR4 memory vendor to ensure the best compatibility so you're assured reliable performance from your favorite brands.
