ASRock X299 Killer SLI/ac Motherboard Review

Here we go with next ASRock motherboard and we hope it will be as exceptional as the last one. This time it’s the X299 Killer SLI/ac so high-end motherboard designed for gaming which supports Intel processors from the Skylake-X and Kaby Lake-X series. We will show you how it performs with the i9-7900X processor, which is quite demanding considering high wattage but also generated heat.

Let’s start with some technical data and main features.

 

 

 

 

11 Power Phase Design

Designed with an 11-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.

Dr. MOS

Dr. MOS design features the latest SPS (Smart Power Stage) technology. It’s optimized for monitoring current and temperature of each phase, thus delivering smoother and neater power to the CPU with enhanced performance and OC capability.

VROC

Virtual RAID On CPU (VROC) is the latest technology that allows you to build a separate RAID array with M.2 NVME cards, using PCIe Lanes coming from the CPU. With VROC, users can setup RAID 0 to speed up the system with ease, not only that, an optional Upgrade Module is also available to open up more RAID options such as 1, 5 and 10.

*Only Intel® SSDs can support VROC 

Dual USB 3.1 Gen2 (Type-A + Type-C)

The newer and more power efficient ASM3142 USB 3.1 Gen2 controller not only delivers up to 10 Gbps data transfer rates but also supports “Multiple Ins” architecture, it is able to maintain fast and stable speed while transferring data from two USB storage devices at the same time without bogging down by their speed difference. 

Dual Band 802.11ac WiFi

No one has time for weak WiFi signals and sluggish internet! That’s why this motherboard comes with a 802.11ac WiFi (2.4G / 5G WiFi) module which supports wireless networks and Bluetooth v4.2.

Intel® LAN

Intel® LAN provides the best throughput performance, lower CPU utilization, enhanced stability and is able to deliver ultimate network experience to users!
 

Hyper BCLK Engine III

An additional external base clock generator that supports PCIe frequency overclocking. It provides a wider range of frequencies and more precise clock waveforms, allowing any user to get most from their CPU investment with precise, stable overclocking.

RGB LED

Build your own colorful lighting system! RGB LED and header allows users to connect LED strip and create their unique PC style easily. The ASRock RGB LED utility can be downloaded directly or from an all-in-one utility ASRock Live Update & APP Shop!

PCI-E STEEL SLOTS

The advanced PCI-E Steel Slots packed with solid cover that prevent any signal interference with graphics cards. It also ensures the heavy graphics cards to be well-installed in the PCI-E slots safely. 

Intel® Optane™ Memory Ready

Supports Intel® Optane™ memory technology and Intel® Optane™ storage technology that redefines a new standard of high performance and responsiveness. 

Triple Ultra M.2

Triple of the world’s fastest PCIe Gen3 x4 Ultra M.2 slots that deliver up to 32Gb/s transfer speed, it also supports SATA3 6Gb/s M.2 modules.

*Performance result may vary with a different configuration.

Digi Power

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.

A-Tuning

A-Tuning is ASRock’s multi purpose software suite with a new interface, more new features and improved utilities.
