The extra large massive aluminum alloy heatsinks dramatically take away heat and cool down MOSFETs, chipsets.


Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.


Combining with two silicon dies into one MOSFET, Ultra Dual-N MOSFET provides larger die area and lower Rds(on), so the power supply for the CPU Vcore is more efficient.


Specially designed for memory power delivery, the new-gen alloy chokes feature a highly magnetic and heat resistant design, thus delivering more stable and reliable power to the motherboard.


Compared to traditional chokes, ASRock's new-gen premium power chokes effectively increase up to three times better saturation current, providing enhanced and improved Vcore voltage to the motherboard.


Nichicon's supreme 12K platinum capacitors! The industry's longest lifespan – 12,000 hours.*
Durability - Others' High-End MBs Caps: 10,000 hours - 12,000 hours*. ASRock's MB With Nichicon last 20% Longer! 12K Platinum Caps
*Tested under industry standard 221°F (105°C) ambient temperature.

The onboard M.2 socket is a new interface for connecting Next Generation Form Factor (NGFF) SSDs or other devices. ASRock is the first in the world to implement PCIe Gen3 x4 M.2 socket on motherboards. The ultimate Ultra M.2 interface pushes the speed up to 32Gbps which is 6X faster compared to other M.2 Gen2 x1 solutions that are limited to 5Gbps. In addition to support PCIe Gen3 x4 M.2 modules, the Ultra M.2 also supports SATA3 6Gbps M.2 modules.
This motherboard is capable of supporting DDR4 ECC and RDIMM (Registered DIMM) memory modules which deliver server-grade performance and durability for high-powered computing systems.
Designed to meet the maximum computing power system, this motherboard supports DDR4 8-DIMM quad-channel memory with maximum capacity up to 128GB.
