ASRock releases two new X299 motherboards, the ASRock X299 Taichi XE and ASRock Fatal1ty X299 Professional Gaming i9 XE. Both Feature a  whopping 13 power phase and additional 2 power phase that ensure memory area's stability.

Dr. MOS solution that is optimized for monitoring current and temperature of each phase, thus delivering neater and smoother power to the system. An integrated Hyper BCLK Engine III controller that provides a wider range of frequency and more precise clock waveforms. XXL Aluminum Alloy Heatsink/Heatpipe design that effectively takes away heat from the MOSFET, thus allowing this mainboard to support up to 450W CPU with airflow condition. The boards are based on a special 8-layer PCB layout that makes it possible to support Quad-Channel memory technology (one DIMM per channel). Users may expect to reach a  DDR4 4400Mhz frequency.
