X99 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 three times better saturation current, providing enhanced and improved Vcore voltage to the motherboard.
X99
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.
X99
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.
X99
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.
X99 X99
Sapphire Black PCB

Pure black PCB appearance. The new Sapphire Black PCB represents rock-solid quality and gives the motherboard a more mysterious touch.
X99 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 32Gbps which is six times faster compared to other M.2 Gen2 x1 solutions that are limited to 5Gbps.
X99X99 X99 X99
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.
X99
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.
X99 15µ Gold Contact in DIMM & VGA PCIe Slot

Unlike other motherboards come with only 3 - 4µ gold contact, this motherboard is coated with 15µ gold contact in the DRAM slots and PCIe x16 slot, thus providing better anti-oxidation protection than usual.
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.
Digi Power

More Precise, More Efficient
Unlike traditional motherboards that use analog power, this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design, which provides CPU Vcore voltage more efficiently and smoothly, so that the stability and lifespan of the motherboard is greatly enhanced.
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)!

Once you shut down your connected HDDs, they will disappear from your file explorer screen. Therefore other people won't even know these HDDs existed, nor can they access your private data stored on these HDDs. You can protect your privacy easily.
X99X99
Many HDDs are used for storing data only, while ODD is not frequently used. However, these occupied HDDs/ODD still consume a lot of energy and increase the internal temperature of the chassis when idle. This eco-friendly design allows you to shut down those devices for saving more energy. You can turn them back on anytime you need them.

Switch on or off the connected HDD/ODD whenever you want! Save more energy!
X99 It is always annoying when your HDDs fail, not to mention the loss of your precious photos, videos, data, etc. By avoiding switching your HDDs on and off frequently, you can protect them from any potential damage and prolong your HDDs' life.
