ASRock Z170 Extreme7+ Features
XXL Aluminum Alloy Heatsink DesignExtra large aluminum alloy heat sinks that effectively take away heat from the MOSFET and chipset so that your whole system may perform more stable.
Combo Caps (Nichicon 12K Platinum Caps)A combination of 820uF and 100uF capacitors. Together these capacitors provide clearer, efficient and more responsive CPU Vcore power, and overclockers may achieve higher scores.
Premium 60A Power ChokeCompared to traditional chokes, ASRock’s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
Premium Memory Alloy ChokeSpecifically designed for memory power delivery, these new alloy chokes feature a highly magnetic and heat resistant design, thus delivering more stable and reliable power to the motherboard and memory modules.
Dual-Stack MOSFET for CPU PowerDual-Stack MOSFET (DSM) is another innovative MOSFETs design by ASRock. The silicon die area is increased by stacking two dies into one MOSFET. The larger the die area, the lower Rds(on). Compared to traditional discrete MOSFET, DSM with larger die area provides extreme lower Rds(on) 1.2 mΩ, so the power supply for the CPU Vcore is more efficient.
Nichicon 12K Platinum CapsSupreme 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.

Retail Packaging

The packaging for the Z170 Extreme7+ is very similar to that of the Z97 Extreme6 that I reviewed a little over a year ago. There’s a fairly simple front with the manufacturer/model listed, with a full feature/spec listing on the back, and once again there’s a handle for ease of carrying.

The Extreme7+ comes with a very nice accessory package. It includes the Quick Installation Guide, Software Setup Guide, an I/O Shield, a 2-slot rigid SLI bridge, the Driver CD, Case Badge, 4x SATA Cables, 3x Screws for M.2 Sockets, 1x Screw for mini-PCIe slot, 1x USB3.1 Front Panel, 4x Screws for Front Panel, 1x SATA Express Cable, and 1x USB Power Cable. My only other comment here is that it’d be nice for the SATA Express cable to be either sleeved or all black.


Here you can see the USB 3.1 Front Panel. This panel includes 1x USB 3.1 Type-A Port and 1x USB 3.1 Type-C Port. The finish on the front is black aluminum with ASRock printed in white.
On the rear of the Front Panel simply hook up the 1x SATA Express cable and 1x USB Power cable then you’ll be ready to go.

The ASRock Z170 Extreme7+

Much like last year, there’s a whole new color scheme for the motherboard. The new color scheme is black and gold, which goes nicely with the gold caps and matte black PCB. There’s a new cover over the I/O ports and audio section. The Purity Sound 3 audio section is based on the Realtek ALC1150 Codec, it is quite an extensive audio section, and it is isolated from the rest of the motherboard. There are also a total of six PWM fan headers scattered across the top half of the motherboard.
Going to the back of the motherboard it is seen that the first PCIe x16 slot is an electrical x16 connection, the second is an electrical x4 connection, the third is x8, and the fourth is also x4. All the heatsinks are attached to the motherboard with screws, which is expected on a motherboard of this level.

A Closer Look

Here we’ll start out at the lower right hand corner of the motherboard. Noticed first are the 3x SATA Express ports and 4x SATA III ports. Further back in the picture are the Debug Display, 3x USB 2.0 headers, and the case switch headers. Also, the CMOS battery is located on the corner of the board, which is much better than between the PCIe slots!
Moving to the upper right hand corner there is the main 24-pin power connector, 2x USB 3.0 internal headers, power button, reset button, and 4x DDR4 DIMM’s. There is also a pair of PWM fan headers and the CMOS clear button on this shot.

Looking at the bottom edge of the motherboard we find a few connectors I’ve already mentioned along with both BIOS chips and the BIOS switch, the CMOS Clear Jumper, the front audio connection, the COM Header, and the TPM connector.
In the expansion slot area of the motherboard there are 4x PCIe 3.0 x16 slots and 2x PCIe 3.0 x1 slots. The lower of the two x1 slots has the rear cut out so that it is a “flexible” PCIe slot, meaning it can accept cards longer than x1. For SLI/CrossFireX in a dual card configuration the second and fourth slots will be used, meaning that you can use a triple slot cooler. There are also 3x Ultra M.2 in this area, along with a MiniPCIe slot. These M.2 slots share bandwidth with the SATA Express connectors, allowing for multi-GPU configurations and M.2 SSD’s at the same time. The connector in-between PCIe3 and PCIe4 is the ThunderBolt AIC connector.

Looking at the rear I/O area you can immediately see that it is loaded with connections. For display there are DVI-D, HDMI, and DisplayPort 1.2 connections. There are a whole slew of USB ports including 2x USB 2.0 ports, 4x USB 3.0 ports, 1x USB 3.1 Type-A port, and 1x USB Type-C port. To wrap up there are 5x 3.5mm audio connections, 1x SPDIF Out connection, and 1x PS/2 port.

Stripping the Extreme7+

Even though the ASRock site lists a 12-phase Digi Power VRM, I counted… 14! From what I can tell this is broken down into eight phases for the CPU, four phases for the iGPU, one phase for the VCCSA, and one for VCCIO. Using a single International Rectifier IR35201, which is a 6+2 phase digital PWM controller. I didn’t see a second controller, so I assume there is some sort of dual driver being used.

Both heatsinks on the motherboard are large and make amazing contact with the components they’re meant to cool. The VRM heatsink is a heatpipe design which helps equal out potential hot spots. As mentioned before both heatsinks are attached with screws, not clips, which helps with the great contact they make.

The impressive, fully isolated audio section of this motherboard is controlled by a Realtek ALC1150 codec. This is currently the top dog in the world of audio and is supported well by ASRock’s circuit design. In this circuit design are two of the TI N5532 Operational Amplifiers which allow for use of headphones and headsets up to 600Ω.

Below you can see both of the Gigabit Ethernet controllers. Unlike quite a few boards with dual LAN, this one has two Intel controllers. The first is the brand new i219V and the second is the slightly older i211AT. These controllers support teaming, allowing you up to double the bandwidth on your Ethernet connection.

UEFI BIOS and Overclocking Software

Up first on the UEFI BIOS is something we haven’t seen from ASRock before, “EZ MODE”. This is a hub where all the system info is seen, along with adjustments for quick CPU overclocking, XMP memory settings, fan settings, and boot order. Hitting the “Advanced Mode” button we come to the typical “Main” screen that we’ve become accustomed to on recent ASRock motherboards.

This slideshow requires JavaScript.

Next up is the “OC Tweaker” section of the BIOS which includes CPU configuration, memory configuration, voltage settings, and user profiles. This gives all the settings for overclocking, tweaking, and saving your settings for later. The memory tweaking area of this motherboard is quite impressive, allowing changes even down to the fourth timing set! Nowhere do I see any settings to overclock the iGPU though.

This slideshow requires JavaScript.

Here’s the “Advanced” section of the motherboard’s BIOS, here are a few power settings for the CPU, the chipset configuration, storage configuration, and more. As seen in the slideshow below, this is where you can edit your C-States, active onboard devices, and more.

This slideshow requires JavaScript.

Now last, but not least, are the Tool, H/W Monitor, Security, Boot, and Exit sections of the BIOS. In the Tool section we find automated systems from ASRock to install drivers, update the BIOS, and more. One standout feature here is the ability to update the BIOS over LAN, which I am quite a fan of and have been since ASRock introduced this feature to their motherboards. Over at the “H/W Monitor” tab there are system temperatures, fan speeds, voltage readings, and fan configuration settings. On the Boot tab you’re able to change the boot priority, enable fast boot, and boot from LAN. Finishing up the BIOS is the Exit section which allows you to save settings, load defaults, and use a one-time override of the boot device.

ASRock’s A-Tuning software has been a nice piece of software for the last few generations and this newest iteration is no exception. The Operation Mode, OC Tweaker, and System Info tabs are largely unchanged, but there was no need to re-do these sections. The new “FAN-Tastic Tuning” section is great to see broken out into its own section, it allows control over all the fans on the motherboard via a user or predefined curve. There is a “Start FAN Test” button here that will also allow you to find the minimum speed that your fans run at easily. The Tech Service and Settings tabs are also unchanged from the last generation.

We’ll perform our usual set of benchmarks which test rendering, memory performance, and single/multi-threaded CPU performance. For 2D benchmarks we’ll use SuperPi 1M and 32M, wPrime, Intel XTU, and PiFast. For rendering it’s Cinebench R11.5 and R15. Memory performance is checked against AIDA64 and MaxxMEM. For encoding we use x264 and PoV Ray. Stock testing is performed with the BIOS as you get it out of the box, which will vary from motherboard to motherboard. When overclocking, a CPU speed of 4.7 GHz will be used for testing purposes. Memory speed is unchanged.

Pushing the Limits

Here’s where I take it up a notch, this screenshot shows a run on Cinebench R15 and SuperPi 1M at 4.8GHz on the CPU and 4.4GHz on the RING. My only voltage change was to set the vCore at 1.42V in the BIOS. With my current cooling I couldn’t run Cinebench at 4.9GHz, looks like I’ll need to wait until winter to give enough voltage for that extra step.

Cinebench R15 and SuperPi 1M 4.8
Cinebench R15 and SuperPi 1M 4.8


Like most of my conclusions I’ll start out with the negatives, but I only found one; no iGPU overclocking options. As an overclocker I want to set any part of this board considering that it’s a range-topper.

On to the positives… oh where do I start? This board is loaded like a good potato. Dual Gigabit Ethernet, 3x Ultra M.2, awesome audio, great VRM. ASRock went a new route with color scheme from last generation, and they’re working it like a model. On top of this, it performs very well pushing my 6700K to 4.8GHz without even thinking about breaking a sweat. It even includes dual BIOS chips, a BIOS switch, and all PWM fan headers. All this along with plenty more toppings that weren’t mentioned.

The bundled software and BIOS are all very familiar to what we’ve seen before, which is a good thing, but they do feature a few improvements such as EZ Mode. I’m glad ASRock didn’t see fit to fix what wasn’t broken. There’s more than enough adjustability in this board for almost any overclocker, whether rookie or veteran.

Now, on to the wallet, the suddenly lighter wallet. This board has an MSRP of $239 and is currently selling at Newegg for $219 AMIR. Looking at the competition for the Extreme7+; Gigabyte G1 Gaming 7, ASUS Sabertooth Mark 1, this price tag is spot on. With the features, pricing, and performance in mind this board is Overclockers approved!
