Features:

Super Alloy
The ASRock Super Alloy design incorporates top-notch materials to achieve unmatched stability and reliability in any situation. XXL Aluminum Alloy Heatsink Design. The Premium 60A Power Choke provides enhanced and improved Vcore voltage to the motherboard. Premium Memory Alloy Choke, specially designed for memory power delivery, enables more stable and reliable power. Ultra Dual-N MOSFET, which combines two silicon dies into one MOSFET, provides a larger die area and lower Rds (on) for more efficient power supply to the CPU Vcore. Nichicon 12K Platinum Caps features more stability and reliability, and lifespans of at least 12,000 hours. Sapphire Black PCB represents rock-solid quality, and gives the motherboard a mysterious touch.

18 x SATA3 (8 x SAS3 12.0GB/s + 10 x SATA3 6.0GB/s)
If you are constantly worried about running out of storage space, ASRock X99 Extreme11 may be the end of your fears. This motherboard is equipped with 10 SATA3 connectors by Intel X99, plus eight additional SAS3/SATA3 connectors by an LSI SAS 3008 controller. This adds up to a total of 18 SATA3 ports that can reach an unearthly 6.1GB/s transfer speed!

4-Way SLI and CrossFireX Supported by Two PLX PEX 8747 Bridge Chips
PLX PEX 8747 is a PCIe Gen3 bridge chip that offers solid PCIe 3.0 lanes for PCIe devices, and is optimized to support high-performance graphics. Via the two PLX PEX 8747 bridge chips onboard, this motherboard is able to support 4-Way SLI or 4-Way CrossFireX at PCIe Gen3 x16/x16/x16/x16 mode with four graphics cards.

Dual Ultra M.2
The two onboard M.2 sockets are a new interface for connecting Next Generation Form Factor (NGFF) SSDs or other devices. ASRock is the first in the world to implement the PCIe Gen3 x4 M.2 socket on motherboards. The Ultra M.2 interface pushes the speed of M.2 modules up to 32Gb/s, which is three times faster than other M.2 Gen2 x2 solutions that are limited to 10Gb/s. Furthermore, this motherboard is capable of powering two M.2 x4 SSD devices simultaneously at 2.8GB/s!

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

HDD Saver Technology
There's a dedicated 4-pin HDD Saver Connector placed near the SATA ports. By connecting it to the HDDs, you can shut down or turn on the HDDs via software when needed. HDD Saver Technology secures more privacy, saves more energy, and extends the HDD's life.
