ASRock Z270 Killer SLI review and test: motherboard with good efficiency

ASRock Z270 Killer SLI review and test: motherboard with good efficiency

ASRock also produced several motherboards by the time the new ad Intel Kaby Lake processors and chipsets. Motherboard Z270 Killer SLI is equipped with an ASRock is not as rich as high-end models of its competitors, but still very interesting. All the details you will find out in our review.

ASRock Z270 Killer SLI is offered at a very attractive price. The motherboard ASRock Z270 Killer has a SLI ATX format, and equipment can be called quite sufficient for most users. Like other models LGA1151 motherboard has four DDR4 DIMM slots. Note two mechanical slot PCIe 3.0 x16 and four PCIe 3.0 x1 add-in card. The first two slots just justify additive “SLI” in the model name.

SSD and HDD are connected via six SATA 6 Gb / s interface and two M.2, note the eight ports USB 3.1 Gen1 and four USB 2.0 periphery. Of course, would not prevent one or two port USB 3.1 Gen2, but the manufacturer has saved them. To connect a monitor or TV to the integrated graphics core available outputs HDMI 1.4b and DVI-D. There is also a Gigabit LAN port, and a built-in audio subsystem.

In addition to the motherboard you get:

  • The plug I / O
  • Quick Installation Guide, software manual, DVD with drivers and utilities
  • Bridge 2-way HB SLI
  • Two SATA cables
  • Two mounting screws M.2
  • A card ASRock Killer

In the case of motherboards entry accessories abundance level should not be expected. What is just right for ASRock Z270 Killer SLI. The package includes a mandatory I / O plug and DVD support. Supplied two SATA cables, SLI-HB bridge two NVIDIA Pascal cards, two screws M.2. As a bonus, you’ll get a postcard in the style of ASRock Killer.

The difference between the chipsets Intel 100 and 200 is not as significant as one might think numbering. In Z170 Intel chipset offers up to 20 Gen3 lines. In the case of Z270 PCH we get four lines Gen3 more, that is, their number increased to 24 Gen3. Additional lines allow you to connect more components. For example, another slot M.2.

Processors Kaby Lake still offer a very limited number of lines – only 16 Gen3, but they can be distributed in at least two slots mechanical PCIe 3.0 x16.

ASRock Z270 Killer SLI review and test: motherboard with good efficiency

ASRock for the CPU power subsystem used ten chokes 40A. Each throttle announced two MOSFET, which are equipped with heat sinks for cooling. For stable operation of the power supply should be connected to an optional 8-pin EPS12V. It provides power to 336 watts, which by the way have in the case of CPU overclocking. On board there is a brand capacitors Nichicon 12K.

Chip Intersil ISL95856 operates as PWM-controller. However, ten phases directly, he can not manage, because ASRock added two Phase Doubler.

ASRock Z270 Killer SLI features four bars DDR4 DIMM, allowing to install up to 64 GB of memory.

Despite the addition of “SLI” in the title, ASRock motherboard supports CrossFireX. However, due to two mechanical slots PCIe 3.0 x16, you can expect a maximum of the configuration of the 2-way multi-GPU. Both slots are connected directly to the LGA1151 processor (Gen3 16 lines), in the case of installing two video cards we get separation x8 / x8. four PCIe slots are also available 3.0 x1, they are connected to the chipset Z270 PCH.

ASRock has used the free space above and below, to install two M.2 M-Key slot. They can be installed SSD modules in length from 3.2 cm to 11 cm. If the module operates in SATA mode, you have to put up with some restrictions. So, if in the upper slot of the module is installed in M.2 SATA mode, 5 SATA port is disabled. Lower slot M.2 leads to blockage of the SATA port 0. On the other hand, if you install a module in the PCIe protocol mode NVMe, nothing will not be blocked.

Also M.2 slots can be seen six “native” interface SATA 6 Gb / s, deployed at an angle of 90 degrees.

Interfaces from left to right from top to bottom:

  • HDMI 1.4b
  • PS / 2, 2x USB 3.1 Gen1 Type A (Intel Z270)
  • DVI-D
  • 2x USB 3.1 Gen1 (1x Type A and 1x Type C, Intel Z270)
  • Gigabit LAN (Intel I219-V), 2x USB 3.1 Gen1 Type A (Intel Z270)
  • Five analog 3.5mm audio ports, optical digital audio output (Toslink)

A set of interfaces to I / O panel can be called average. Integrated graphics LGA1151 processor core can be displayed through the HDMI 1.4b and DVI-D. Note PS / 2 port for connecting the old keyboard or mouse. The manufacturer installed six ports USB 3.1 Gen1, but by USB 3.1 Gen2 will have to give. There is a Gigabit LAN port, five 3.5-mm audio jacks and optical digital output Toslink. If you buy an option ASRock Z270 Killer SLI / ac, you will get and Intel WLAN module AC and Bluetooth 4.0, which is installed between the video output DVI-D ports and two USB 3.1 Gen1 Type A.

Chip Nuvoton NCT6791D Super I / O is responsible for monitoring temperatures, voltages and fan speeds.

On ASRock Z270 Killer SLI mounted audio controller ALC892, although we expect to see ALC1150, if not fresher ALC1220. Next to the controller, you can see four audio capacitor, which promise to give better sound quality.

ASRock has established a network controller Intel I219-V, providing speeds of up to 1 Gbit / s and supports features such as VLAN and Wake-on-LAN.

According to the general layout of complaints we did not have. It’s nice that ASRock has left space under the top slot PCIe 3.0 x16, so the dual-slot video card will not block anything.

For the motherboard, you can connect up to four 4-pin fans. All fans can be controlled. The BIOS available modes “Silent Mode”, “Standard Mode”, “Performance Mode” and “Full Speed”. No preset profiles, but you can control the fan manually via the option “Customize”. You can specify four settings temperature / fan speed, and set critical temperature threshold.

ASRock Z270 Killer SLI BIOS

On ASRock Z270 Killer SLI at the time of the tests already installed the latest version of the BIOS L1.11B, which has left a positive impression. Although we encountered some problems overclocking, but more about them below.

As might be expected, did not change the ASRock UEFI. The Taiwanese manufacturer offers an overview page where you can see all the major parameters. There is not only the time and date, CPU temperature and motherboard, CPU voltage, but also a model of the motherboard installed BIOS version and model of the processor, including the base frequency. You can see in which DIMM slots, memory modules, which are capacitance and frequency. If necessary, you can activate profiles Extreme Memory Profile. Below, you can see which ports are connected drives. On the right you can change the boot priority simply moving icons devices. Finally, closer to the center of the fan speed displayed.

A “CPU EZ OC” you can activate the automatic overclocking. On the right you can see the startup icon “System Browser”, “Instant Flash” and “Internet Flash”.

Color UEFI ASRock has adapted to its line of Fatal1ty – it’s red. Option “My Favorite” allows the user to add frequently used functions into a separate UEFI menu “My Favorite”. Unlike ASUS, ASRock did not create a separate tab, limiting the menu item in the “Main” page. Also different and how to add features. Please select the function you want to add to the list. In the upper right corner under the item “Exit” has a “My Favorite” button. Next will be the star, where you want to click.

The rest of the menu structure of the former. The user can specify the tab that will be displayed when you call the UEFI interface. All overclocking brought to the tab “OC Tweaker”. But instead of all the functions on the same page, they are divided into three menu items: CPU Configuration, DRAM Configuration and Voltage Configuration. All overclocking settings can be stored in five profiles available. They can be stored on a USB-stick and imported back into the UEFI. On the page “Advanced”, you can manage settings related to integrated components. It also offers familiar tools: System Browser, Online Management Guard, UEFI Tech Service, Easy RAID Installer and Easy Driver Installer. UEFI, you can update to the latest version optionally via Instant Flash or Internet Flash. You can store up to three settings, profiles, supports import and export.

With hardware monitoring function, you can watch the temperature of the CPU and motherboard, voltage and fan speed, as well as to control the latter. On the “Security” you can protect access to password-UEFI. Download settings are located in a separate tab “Boot”. You can set the boot priority and other settings. Finally, there is an item “Exit”, which is clear by name.

Regarding UEFI our complaints have arisen. ASRock well laid out menu navigation using the mouse and / or keyboard. All settings are made correctly, complaints in this regard have not arisen. The stability of the motherboard too great.

ASRock Z270 Killer SLI: Acceleration

ASRock motherboard chipset equipped Z270, so processors Core i5-6600K / 7600K and Core i7-6700K / 7700K can be quite comfortable to disperse. The power system is powerful enough, it is based on the ten phases.

UEFI ASRock Z270 Killer SLI allows you to change the base frequency from 100 MHz to 538.02 MHz in 0.1 MHz. CPU voltage can be set in the Override and Offset modes. In Override mode, you can set a fixed voltage from 0,900 V to 1,520 in steps of 0.005 V. The bias voltage mode exhibited from -100 mV to +500 mV.

Core i7-7700K processor stably worked a maximum of 4.8 GHz. In the BIOS we set the voltage of 1,270 V. But was not that simple to test the stability. We saved the settings in the BIOS, and the system freezes during the Windows boot. The solution was to disable and “cold” system start.

With platform Kaby Lake, we again performed memory overclocking. We used two DIMM module capacity of 4GB – “G.Skill RipJaws4 DDR4-3000”. In the first test we will check the XMP functionality, and memory overclocking second hand, without using XMP.

With profiles Extreme Memory problems have arisen. Manually, we also successfully put a clock frequency of 3.000 MHz. VDIMM in both cases were put on 1.35 V.

We will use our standard test system with the motherboard ASRock Z270 Killer SLI.


  • Intel Core i7-7700K
  • Corsair Hydro H110i GT
  • Test Socket LGA1151 motherboard chipset Intel Z270 / H270 / B250
  • 2×4 GB DDR4-3000 (G.Skill RipJaws 4) – @ 2133 MHz, 15-15-15-35 2T, 1.2 in
  • ASUS Radeon R9 380 Strix
  • PSU Seasonic X-Series 560W
  • Samsung CDDVDW SH-222AB
  • OCZ ARC 100 GB SSD 240

To test the bandwidth used by other components.


  • Windows 10 Pro 64-Bit, Version 1607 (Build 14393)
  • AMD Crimson Edition ReLive 16.12.1
  • Intel INF-Utility

For other drivers, we used the latest version.

After entering the market of processors on Nehalem microarchitecture and integrate a memory controller on the CPU, the performance difference between motherboards become negligible. This is not surprising, because the manufacturers have disappeared almost all optimization mechanisms. In the past, they could optimize the chipset settings to squeeze one or two percent of the performance of the motherboard, but this possibility has disappeared. We conducted our tests the memory modules in the mode of 2.133 MHz and latency 15-15-15-35 2T, and all motherboards, allows you to adjust memory timings, showed similar performance.

Although comparative performance tests of motherboards and are not able to give such a difference, as before, they are still interesting. The fact that the tests allow you to quickly evaluate how different manufacturers implement support functions such as the Turbo, or rely on background overclocking tricks. In the motherboard ASRock Z270 Killer SLI we had to turn off the Multi-Core Enhancement function to a fair comparison.

But in our tests, we were limited to only four applications, namely 3DMark 2013, SuperPi 8M, Cinebench 11.5 and SiSoft Sandra 2014 Memory Benchmark:

3DMark 2013

SiSoft Sandra 2016

The values ​​of the performance of three tested motherboards were quite expected.

We tested the download time. We measured the time in seconds it takes the motherboard initialization of all components to boot Windows.

Load time

In the motherboard ASRock Z270 Killer SLI has a very nice feature – it boots in less than ten seconds.

Today, the question is quite relevant PC power consumption, energy consumption and the difference between motherboards is far more common than the difference in performance. On the one hand, it can be associated with BIOS, Intel wherein power saving functions may be implemented or not completely correct. Or simply disabled by default. Or inactive integrated components when they are replaced by additional chips, or simply not used, is not turned on and continue to consume energy. The power supply circuit also contributes to the overall power consumption, since it can provide more energy than is required components. Yes, and efficiency (efficiency) power supply system is also very important. If the efficiency is low, the system consumes more energy from the power supply. We should not underestimate the role of management software, the entire power supply system must be balanced and coordinated in order to ensure an acceptable efficiency.

At ASRock Z270 Killer SLI, there are several additional controllers. Namely LAN-controller and audio codec, which contribute to the overall system power consumption.

We measured the power consumption of the system in idle mode under Windows, as well as a full 2D-load Cinebench 15 and Prime95 (torture test, full load). The following is the power consumption for the entire system.

Test 1: The built-in components are active

In the first test run, we left the default settings when the motherboard most of the integrated components are active. We used the graphics card Radeon R9 380. As we have noted above, all power-saving features included, we did not make any optimizations manually.

Energy consumption

For the most part ASRock Z270 Killer SLI include lower power consumption compared to the ASUS Maximus IX Formula and Gigabyte GA-Z270X-Gaming 7. In our idle on the motherboard ASRock system consumes only 34.7 watts. The other two motherboards consume significantly more.

Under load, the difference was less Cinebench. We got the power consumption of 117.1 watts, 5.1 watts of the same ASUS Maximus IX Formula with 122.2 watts level.

When the load increases on the system of difference with the motherboard ASUS become even smaller. ASRock Z270 Killer SLI with the test system consumed load of Prime95 125.1 watts. But the difference with the ASUS motherboard was only three Watts.

In CPU-Z we got the CPU voltage under full load 1.2 V, the minimum result of the three tested motherboards.

Since most people are all embedded controllers are not required, we conducted another test run, during which the components of the integrated LAN controller is only activated and sound chip. All additional controllers USB 3.0 and SATA we disconnected. The motherboard is still exhibited voltage levels automatically, but we have to manually set up all power-saving features. We continue to use the graphics card Radeon R9 380.

Test 2: The integrated components are disabled (active 1x LAN + sound)

Energy consumption

We were not able to disable add-ons, so power consumption old.

In general, the motherboard ASRock Z270 Killer SLI showed convincing results in power consumption. Under load, we also got quite a low level of power consumption.

Performance USB 3.1 Gen1

The motherboard ASRock Z270 Killer SLI has eight USB 3.1 Gen1 ports. Six of them are brought to the I / O panel, two more are available through the internal comb. All of them are connected directly to the chipset Z270 PCH. In order to test USB 3.1 Gen1, we used the same solution as for USB 3.1 Gen2. Namely, the outer snap Akitio NT2 U3.1, in which we installed two SSD OCZ Vector 150 with a capacity of 480 GB in a RAID 0 array.

Intel USB 3.1 Gen1 controller showed a good level of performance USB 3.1 Gen1. We got up to 441 MB / s read and up to 463 MB / s write. Excellent result.

Performance SATA 6G

The motherboard ASRock Z270 Killer SLI are six ports SATA 6Gb / s. All of them are connected to the chipset Z270 in native mode. For the tests we took SanDisk Extreme 120 drive that is connected directly to the SATA ports.

By reading performance controller SATA 6Gb / s from Intel showed a good result 554 MB / s. Is that on the record performance may be higher. We got a rate to 514 MB / s.

Performance M.2

The platform Kaby Lake S, we continue to test M.2 interface. Chipset Intel 200 allows you to squeeze out M.2 modules a high level of performance thanks to four lines PCIe 3.0, the theoretical capacity is 32 Gbit / s. For M.2 slot test, we used a Samsung SSD SM961 capacity of 256 GB and 8 cm long. Indicates the Samsung for its drive read speed of 3,100 MB / s and write speed of 1,400 MB / s. NVMe SSD supports version 1.2 of the protocol, the connection is made to the Z270 chipset Gen3 on four lines.

Performance module M.2 has been very decent. By reading we got up to 3.380 Mb / s, recording – up to 1,515 MB / s.

ASRock Z270 Killer SLI from ASRock – one of many new LGA1151 Motherboard chipset Intel 200. We have already tested two high-end motherboard, but ASRock innovation closer to the mass segment. The motherboard has a ASRock Z270 Killer SLI ATX format, this equipment is very worthy. LGA1151 CPU Power provides ten phases, which are able to cope with overclocking. Is that a user would have to abandon the integrated features improve comfort, such as the power button or reset. As might be expected, ASRock has established four memory banks DDR4 DIMM, allowing to install up to 64 GB of RAM.

On the motherboard ASRock Z270 Killer SLI has two mechanical PCIe 3.0 x16 slots, thanks to which SLI additive was obtained. Both slots enhanced function Steel Slot. For the expansion card slot provides four PCIe 3.0 x1. Interfaces drives presented six ports SATA 6Gb / s and two slots M.2 M-Key. The modules can be installed last in length from 3 to 8 cm.

There are eight ports USB USB 3.1 Gen1 standard and a four-port USB 2.0. The motherboard has a Type C port on the I / O panel, but it applies to the USB standard 3.1 Gen1. Unfortunately, the manufacturer saved on the controller USB 3.1 Gen2. If you want to display a graphic processor core, then ASRock Z270 Killer SLI available outputs HDMI 1.4b and DVI-D. Connecting to the network can be made via the Gigabit LAN port, implemented through the Intel I219-V controller. In the case of option ASRock Z270 Killer SLI / ac available and WLAN module that supports 802.11ac and Bluetooth 4.0. Both motherboards are based on the built-in audio subsystem controller Realtek ALC892. It is a pity that ASRock has not chosen a more modern ALC1220 or the same ALC1150.

ASRock UEFI established with the familiar interface. Feature any we found no problems. Is that in the acceleration test had to perform a “cold” start to setup worked as expected. Here, of course, the ASRock can make improvements. We turn to the power consumption: idle mode, we got a very low power consumption, under load – the standard level.

In Europe it will have to pay 150 euros . The price can be called quite high, given the equipment, but in the coming weeks it will certainly decrease. So far, for the same price you can buy MSI Z270 SLI Plus, which is not only equipped with the best audio codec Realtek ALC1220, but also provides a two-port USB 3.1 Gen2 controller through ASMedia ASM2142.

Benefits of ASRock Z270 Killer SLI:

  • Good CPU power subsystem, plenty of overclocking
  • PCI Express 3.0 Support on two PEG slots
  • Very good overall performance, good stability
  • Magnificent idle efficiency, good efficiency under load
  • 2 two slots 32 Gbit / s each

Disadvantages ASRock Z270 Killer SLI:

  • High price
  • No USB 3.1 Gen2 ports
  • Audio controller is not the most modern

On the technical side ASRock has presented a very convincing entry-level motherboard. But in terms of price / Z270 Killer SLI quality does not look so good.
