Features


Server-Grade Power Design

This motherboard is equipped with all switching power design, one set for transferring 3.3V voltage to 1.5V, the other one for 3.3V to 1.8V, delivering improved power efficiency compared to linear design. The ultra compact power design features server-grade high efficient power delivery with less energy consumption, thus offering better power efficiency to the system.


Server-Grade Intel® Dual LAN

Both of the Intel® Ethernet Controller I217LM and I210AT are low-power gigabit network controllers that can be used for server and workstation system configurations.

12 Power Phase Design

Designed with a 12 Power Phase design, this motherboard features sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capabilities and enhanced performance with the lowest temperature for advanced gamers as well.

Ultra Thin Design to Fit 1U Chassis

The back of motherboard is mounted with ultra short screws and the length of the CPU back plate is less than 3mm, allowing this board to fit in server-grade 1U chassis.
Ultra Thin DesignOther MB’s Design

XXL Aluminum Alloy Heatsink Design

The extra large aluminum alloy heatsinks take away heat dramatically. As the MOSFETs and chipsets areas are well covered by these heatsinks to protect them from overheating, MOSFET and chipsets can perform with lower temperature, and your motherboard and system will be more stable and reliable.

Premium 60A Power Choke

Compared to traditional chokes, ASRock’s new-gen premium power chokes effectively increase up to 3 times better saturation current, providing enhanced and improved Vcore voltage to the motherboard.

Premium Memory Alloy Choke

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.

Ultra Dual-N MOSFET for Memory Power

Combining 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.

Nichicon 12K Platinum Caps

Supreme 12K platinum capacitors with lifespans of at least 12,000 hours. Compared to other counterparts on high-end motherboards that merely have lifespans of around 10,000 hours, ASRock applied Nichicon 12K Platinum Caps that offer 20% longer lifespans and provide more stability and reliability.

* Tested under industry standard 105 degree Celsius ambient temperature.

Sapphire Black PCB

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

Supports DDR4 ECC / RDIMM Memory 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.

* ECC is supported with Intel® Xeon® processors.

128GB Memory Support

Designed to meet the maximum computing power system, this motherboard adopts Quad-Channel 8 DDR4 DIMM slots. Each slot supports 16GB memory module, thus delivering a maximum capacity up to 128GB.

Supports NVIDIA® 4-Way SLI™, AMD 4-Way CrossFireX™

This motherboard comes with more than enough PCIe slots that supports multi-GPU 4-Way SLI and 4-Way CrossFireX at x8/x8/x8/x8 mode.

Ultra M.2 (PCIe Gen3 x4)
The World’s Fastest M.2 Socket - PCIe Gen3 x4

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 32Gb/s which is 6X faster compared to other M.2 Gen2 x1 solutions that are limited to 5Gb/s.



Purity Sound™ 2

Purity Sound™ 2 includes 7.1 CH HD audio with Realtek ALC1150 audio codec, 115dB SNR DAC with Differential Amplifier, TI® NE5532 Premium Headset Amplifier, cap less Direct Drive technology, EMI shielding cover, PCB isolate shielding and DTS Connect. As Nichicon audio capacitors are what every audiophile has been longing for on a PC, ASRock applied these high quality capacitors for Purity Sound™ 2.

This frequency response chart was tested with 32 ohm normal headphones. It indicates how traditional audio solution's frequency response drops drastically at low frequencies. Compared to traditional audio solution's (2.0dB) at 20 Hz bass low freq area, Purity Sound™ 2 still maintains its frequency response (0.4dB) and provides better bass with the TI® NE5532 amplifier, improving the bass quality by 20% (1.6dB)!
