The ASRock 'FATAL1TY' X99X Killer is a serial killer that you want to have on your side. Okay, okay – so it’s not really a serial killer (at least not during the daytime), but the ASRock X99X Killer completely kills the competition in terms of a budget gaming board that delivers in a lot of ways in terms of all the current ASRock X99 offerings. The MSRP of $289.99 comes with this board that is layered with a black/red design surface and adorns the X99 emblem of CPU support. The board itself features Super Alloy components, which are simply stunning, ranging from the Aluminum Alloy heatsinks, to the Power Choke 60A that provide for better current saturation across the PCB. The ASRock X99X Killer also comes with the Killer e2200 LAN which is something that we only see in higher end boards, and it’s a great thing to see this being used here for network performance being optimal per gaming packet.

Being the choice for the hardcore gamer on a budget, ASRock really delivers something for the value. The ASRock X99X Killer comes with the Realtek 1150 powered chipset that runs across the I/O with support for Purity Sound 2.0 – a real nice software multiplexer for audio that can handle 7.1 surround sound before the world starts looking to 12.1 for consumer use.

Intel Haswell-E Features

First Desktop Platform To Feature DDR4 Memory Support

Coming to the memory controller,  Intel’s Haswell-E is officially the first HEDT platform to feature support for DDR4 memory. The DDR4 memory controller lies on the processor itself through which it is directly connected. The new DDR4 memory modules consume only 1.2 V of power compared to 1.65/1.5V standard with DDR3. The can feature upto 16 banks of memory and require a 288-Pin DIMM connectors which would be available on the new X99 chipset motherboards. The DDR4 memory controller offers Quad channel memory support. DDR4 would offer faster clock speeds and the Haswell-E platform supports frequencies o 2133 MHz, 2667 MHz O.C +.

LGA 2011-3 Socket Supports Haswell-E Processors

Intel is also preparing the latest LGA2011-3 socket which has similar dimensions but a different ILM key pattern which allows only for Haswell-E processor compatibility. Intel adds compatibility for both their Channel DRX-B Liquid cooler and T-HPHS air cooler with the LGA 2011-3 socket for Haswell-E processors.

Better Overclocking Support For Overclockers

Just like Haswell and Ivy Bridge-E before it, Haswell-E  retains the great overclocking features that  ship with the “K” series and “Extreme Edition” processors. Both the memory and processor can be overclocked beyond limits with unlocked turbo limits, unlocked core ratios in 80/100 increments, programmable iVR voltage, support for XMP mode, unlocked memory controller and voltage limits, native support for memory upto 2667 MHz, Unlocked PCH and PLL voltage controls and more. A single Haswell-E processor would feature 2 x16 and 3 x8 Gen 3 PCI-e support with 40 lanes and would be directly connected to the DDR4 memory controller and the Wellsburg X99 chipset. The feature set would remain the with technologies such as SSE4, AVX, VT, AESNI under its belt.

    ASRock FATAL1TY X99X Killer Unboxing

    The ASRock X99X Killer is not shy about blood on the box – which is streaked with a cut across the front as if a knife cut into the box. The center has a red vignette which contrasts with the black of the rest of the box very nicely.

    When you unwrap the main board packaging - you are greeted by the ASRock X99X Killer (not holding his trademark knife or wearing his trademark Pyramid Head).

    ASRock FATAL1TY X99X Killer – A Closer Look

    The ASRock X99X Killer is a professional grade motherboard which makes use of high grade components to feature better stability and last longer than traditional motherboards. The board comes with the LGA 2011-3 socket which is able to support the Intel Haswell-E processors - including the 8-Core Intel Core i7-5960X.

    x99xkillercloseIn terms of design, the ASRock X99X Killer makes use of a 12 Phase PWM and the socket is powered by a 8-Pin+4-Pin EPS connector scheme in addition to the 24-Pin power connector that provides juice to the board. Thes high quality Super Allot components include the 50G Aluminum Alloy heatsinks, Premium Alloy Chokes, Dual-Stack MOSFETs, Japanese made high-quality conductive polymer   platinum capacitors which all help to make this run faster. The color scheme is red and back for the board which is similar to the ASRock X99 FATAL1TY series, another X99 board that has some of the X99X Killer features plus a tiny bit of things (4-Way SLI support - though realistically 4-way SLI is overkill if you ask me).

    The board has four sets of heatsinks, two for the PWM and power area which are located on the top and interconnected via a heatpipe while the second set is located over the PCH and below the socket which are also connected through a heatpipe. The design is quite elegant and we can see several components scattered across the PCB so ASRock is making use of every inch of the space they can get. All of this combines with full spike protection from surge, lightning, or even electric static discharge – super impressive.

    For storage, the ASRock X99X Killer provides 10 SATA 6 GBps ports, two USB 3.0 header and two USB 2.0 headers. A Dual BIOS and Diagnostic LED can be found below the SATA ports. Expansion slots include 5 PCI-e 3.0 x16 slots which are provided extra power through a 4-Pin connector near the bottom of the board. The board supports both AMD CrossFire and NVIDIA SLI Multi-GPU functionality. There’s also the Ultra M.2 slot, mPCI-e in addition to the mPCIe slot and 4-Pin Molex connector which adds additional power to the PCI-e expansion lanes while using several cards.

    Being a FATAL1TY motherboard, ASRock has also included their Purity Sound 2 design on the PCB which is isolated from the rest of the components and has an ALC1150 codec underneath the EMI shielding and the Killer E2200 LAN chip which is placed right next to another mPCIe port which can be used for WiFi and wireless connector cards. The I/O on the motherboard includes 2 USB 2.0, 6 USB 3.0 ports, a PS/2 port, e-SATA port, Killer E2200 Gigabit Ethernet LAN ports and a 7.1 channel HD audio jack.

    ASRock FATAL1TY X99X Killer - Gaming Benchmarks

    CRYSIS 3

    Crysis franchise is the crown jewel for the PC gamers. Even after going multi-plat, the game is considered to be the most brilliant and gorgeous game ever brilliant, a visual marvel in short. The third and most probably the last title in the Crysis trilogy blends in the most deepest story line of the franchise with graphics that would make any other game cry in shame. Powering the game is the beastly and much user friendly CryEngine 3 that adopts all the features of DirectX 11 API. Simply speaking, the game demands a high performance graphics card than a high performance CPU to play well on higher settings.

    BioShock Infinite

    Destroying a giant floating bird as Booker DeWitt and saving a girl is all part of the job description in this sky utopia thriller by makers of the popular BioShock – Irrational Games. The video game is absolutely gorgeous with full settings, greatly optimized, and one that a benchmark is just calling out for.

    Power Consumption / Thermals / Audio Quality

    The ASRock X99X Killer surprised me quite honestly. Not that I expected little of it, but for the price point I did not expect it to come bundled with so many features to rival a more costly motherboard. ASRock has really done me proud in terms of its quality and dedication to building motherboards, and the ASRock X99X Killer is one of their stars. The Haswell Core i7-5930K has temperatures similar to the Ivy Bridge-E processors - and runs slightly cooler at default settings but as soon as its overclocked, the CPU pushed around the 83-94C even with my top-end air V8 GTS cooler.  A water cooling setup is recommended for 24/7 overclocked usage.

    The audio quality from RightMark Analyzer registered as "Very Good" - which is exactly where people want to be when it comes to audio benchmarking. My only gripe with the audio here is that Dolby Digital Live was not licensed instead of DTS. As much as DTS is relevant, I felt a gaming-central board would take more advantage of the most common medium technology in the form of Dolby Digital Live - which packs any source into a 5.1 channel stream (not upmixed). The quality in Dolby Digital offering seems to be more developed in terms of R&D than DTS when it comes to gaming support (most support analog HD surround or Dolby Digital). Definitely this is a slight disappointment of this board, but it seems that ASRock is trying to go for a higher medium that is less lossy than Dolby Digital.


    The ASRock FATAL1TY X99X Killer build is exceptional, the attention to software detail is great, and all in all the board performs admirably well in comparison to other X99 boards.  If you are a hardcore gamer but don't have the budget for a $399.99 or $450-$499.99 MSRP X99 motherboards, this is the one I would highly suggest. The price difference seems to be the only real difference between the ASRock X99X Killer and the most expensive offerings currently.

    The ASRock X99X Killer motherboard gives hardware enthusiasts the modesty of price along with luxury in the sense of value. It also totally stabs the competition and earns it's name as a real killer in this X99 market.
