As Intel continues its dominance in the mid/high-end PC market, its mainstream LGA1150 socket remains the platform of choice for most DIYers with a relaxed budget and a penchant for performance. Since Haswell’s debut in summer of 2013, we’ve already seen one new set of refreshed chips from Intel (codename Devil’s Canyon) which required a BIOS update to work in 8-series motherboards. The new 9-series boards however did not and they will be compatible with Broadwell as well, the next CPU microarchitecture for LGA1150 due sometime in 2015. Suffice to say if you’re in the market for a Haswell board right now, a H97/Z97 model is highly recommended if a CPU upgrade is a possibility in the future.

Aside from new CPU compatibility, the main difference between the 8-series and 9-series is support for M.2 and SATA Express, storage interfaces that can use two PCI-E 2.0 lanes to surpass the throughput limit of traditional SATA which is capped at 6 Gbps, a figure which is now bottlenecking the capabilities of high-end SSDs. M.2 is essentially the mSATA equivalent of SATA Express and such drives are currently available while full sized SATA Express devices have yet to hit the market. Like their 8-series counterparts, the H97 and Z97 chipsets are basically differentiated by two things. The Z97 can split its available PCI-E lanes for more varied graphic card support, and it is capable of CPU overclocking, making it the better choice for gamers and enthusiasts.


The ASUS Z97-PRO.

Our first Z97 motherboard comes courtesy of ASUS which of course has a whole series Z97 models available at various price-points with differing feature-sets. The Z97-PRO is an ATX variant near the US$200 level that also comes in a second version the Z97-PRO(WiFi-ac), which is completely identical except for the inclusion of a wireless 802.11ac/BlueTooth 4.0 module. Interestingly, this second pricier model is more widely available, at least in North America.

The chipset provides a pair of PCI-E 3.0 16x slots which run at 8x/8x in dual configuration (there’s a third PCI-E slot but it’s 2.0 4x slot), along with SATA 6 Gbps and USB 3.0 support with the latter two complemented by additional ports via add-on ASMedia controllers. Not all Z97 boards implement SATA Express but it’s available here, along with its smaller-sized M.2 counterpart, sharing an interface so only one or the either can be used at a single time.

Complementing these core features are a hefty pair of VRM heatsinks around the socket, a physical power button directly on the board, and a POST code display. The board is also equipped with Crystal Sound 2 which means the onboard Realtek audio controller and associated circuitry is EMI-shielded and there’s an amplifier chip as well. It’s similar to the Audio Boost feature on the last motherboard we examined, the MSI A88XM GAMING.

Accessories.

The Z97-PRO ships with the usual accompaniments including manuals, a driver disc, I/O shield, and four SATA data cables. The only things that can be considered “extras” are the Q-connectors which makes it easier to connect the front panel features and an SLI bridge.

PHYSICAL DETAILS

The ASUS Z97-PRO has a relatively traditional layout for an ATX motherboard, with the CPU socket near the top and most of the onboard headers conveniently located along edges of the board. The most difficult spot to connect is the 8-pin EPS12V connector located between the corners of the VRM heatsinks, which most manufacturers have unfortunately concluded is the most pragmatic location. In tighter cases, you may want to connect this port before the board is installed.


The only thing that really stands out on a visual level are the gold-tinted VRM and PCH heatsinks which give it a luxurious accent. There are three physical PCI-E 16x slots, but only the top two are of the 3.0 variety, though they run at only 8x when both are used. More notable are the whopping six fan headers scattered the edges of the board, five of which are controllable.


The capacitors and inductors surrounding the CPU socket are arranged in a meticulous manner. The Z97-PRO has a 12 power phase design with a pair of chunky gold and black heatsinks for cooling.


The Z97-PRO is flush with storage options. The two black SATA 6 Gbps ports are wired to an ASMedia controller, the four gray SATA 6 Gbps ports are native to the Intel chipset, and the three on the end form a single connection for a SATA Express device. With a PCI-E interconnect, M.2/SATA Express can push up to 10 Gbps. For those living in the present, it’s backwards compatible, providing connections for two more SATA 6 Gbps drives.


At the bottom of the board are a couple of enthusiast-friendly features. A hardware power button is essential for tinkering without a case, and a POST code display helps diagnose the issues that inevitably crop up.


All the typical connectors are available on the back panel including 4 x USB 3.0 ports, and the four main video output methods: VGA, DVI-I, HDMI, and DisplayPort. There’s also a small slot designed for ASUS’ WiFi GO! wireless module which comes included with the Z97-PRO(WiFi AC) model.


The area around the CPU socket on the trace-side of the board is fairly clean. It does not appear that any of the components on this side can interfere with larger heatsink backplates.

BIOS/UEFI

Since its debut, ASUS’ UEFI BIOS has been improving incrementally with each new iteration. The latest version is powerful with a wide array of frequency, voltage, and settings that allow overclockers to hit high clock speeds while also supplying consistent power to vital components to ensure stability. There are also a series of little flourishes that make life a bit easier for the typical enthusiast such as brief explanations of each setting, the ability to bookmark specific settings for quicker access, and a summary of all the changes made being presented before exiting.


By default, the UEFI BIOS utility launches in EZ Mode, not only to simplify the interface for neophytes, but also to present the most relevant system information condensed in one handy screen.


Advanced mode is more detail-oriented but enthusiasts from the old school may not appreciate the ample spacing between the items which limits how much is visible at one time. There are a ton of options so quite a bit of scrolling is required to see everything available.


The most notable aspect of the vast AI Tweaker menu is the ability to change the voltage using an offset, which applies a +/- difference no matter what state the system is in. There’s also an adaptive mode which does the same thing, but only when Turbo Boost is active. A full list of the available settings can be found in the manual.


If you rarely use the reset button on your face, you can use it turn on the system and go directly into the BIOS without having to repeatedly click the “DEL” key (which sometimes miraculously doesn’t work). Hook up the appropriate header and enable DirectKey in the BIOS and you’re ready to go.


Fan control is the one area that is noticeably improved compared to previous versions of UEFI BIOS. For starters, PWM control is now available for every header, not just the CPU fan header. Furthermore, they’ve added a middle temperature/fan setting to manual mode, putting an another point on the fan control graph so it’s not just a straight line.


In fact, ASUS has actually put in a basic version of Fan Xpert in the BIOS called “Q-fan,” allowing you to adjust the plot points on the graph visually. The fans can even be tuned to determine their minimum speeds to ensure they don’t accidentally get turned off by Q-fan.


And finally, the ability to use temperatures other than the CPU to dictate
fan speed change has been included. This feature is limited to the board’s
sensors so fans can’t be set to react to hard drive or graphics card temperatures.
You can use an external sensor by plugging it into the provided T-sensor
header and taping it to the graphics card but this is strictly an aftermarket
option.

This data is enough to give us a very good estimate of DC demand in our test
system. We extrapolate the DC power output from the measured AC power input
based on this data. We won’t go through the math; it’s easy enough to figure
out for yourself if you really want to.

Testing Procedures

If available, the latest motherboard BIOS is installed prior to testing. Certain services/features
like Indexing, Superfetch, System Restore, and Windows Defender are disabled
to prevent them from causing spikes in CPU/HDD usage. We also make note if energy
saving features like Cool’n’Quiet, SpeedStep or S3 suspend-to-RAM do not function
properly.

Our main test procedure is designed to measure the overall system power consumption
at various states. To stress the CPU, we use Prime95 (large FFTs setting). After 10~15 minutes of load (when temperatures stabilize), We also measure the hottest points on the external heatsinks using an infrared thermometer.

Finally, storage subsystems are tested briefly using CrystalDiskMark (1000 MB of 0x00 fill test data) and a Kingston HyperX 3K 120GB solid state drive.

TEST RESULTS

Power Consumption

Note: Motherboards vary in regard to stock Turbo Boost settings so more aggressive models consume more power which is a detriment when using energy efficiency as a metric. So for these tests, all the boards compared have been tweaked to use the exact same clock speeds (a multiplier of 39x/38x/37x/36x for 1/2/3/4 core operation on our Core i7-4770K test chip) to ensure a level playing field.

Compared to previously reviewed Z87 models, the Z97-PRO consumed slightly more power than average on light loads but it should be noted that it, along with the Gigabyte Z87X-UD5, have more advanced feature-sets than the rest of the field. However, it was the most frugal board overall on heavily load suggesting superior high power voltage regulation.

Cooling

To test the board’s cooling, the CPU was stressed for ~15 minutes with Prime95. Temperatures of the boards’ chipset heatsinks were recorded using a spot thermometer. The highest temperatures were taken for comparison.

The Z97-PRO can boast the lowest average heatsink temperatures with both the PCH and VRM heatsinks staying relatively cool during load. Take these numbers with a grain of salt though, as we assume the thermal contact between the chips and the heatsinks is equal.

SATA 6 Gbps Performance

We’re not aware of any differences between the native SATA controller in the Z97 and Z87 chipsets, but the Z97-PRO produced a superior result in CrystalDiskMark compared to the Gigabyte Z87X-UD5, particularly in 512K sequential reads and 4K random writes. Like most third party controllers, the ASMedia 1061 couldn’t keep up with the native solution but with significantly faster 512K write speeds, it did outperform the Z87X-UD5’s Marvell controller.

Boot Performance

To test boot time, the BIOS/UEFI was optimized by setting the hard drive recognition and other delays set to minimum, taking care not to disable common functionality like full USB support, POST messages, etc. and measured the time it takes to reach the Windows loading screen (we stop here because this is the point where the O/S and drive become factors).

Despite having a complex UEFI BIOS and quite a few extra features, the Z97-PRO completes the boot sequence swiftly, entering the Windows 7 loading in under 10 seconds, a good 2~3 seconds faster than Z87 models from Intel and Gigabyte, and almost twice as quick as the ASUS Maximus VI Impact.

Software

The Z97-PRO ships with their all-encompassing AI Suite, as well as few other useful utilities to round out their software experience. The only real hiccup we encountered during our time with the board was getting AI Suite installed. After setting up Windows 7 and all the drivers, AI Suite simply refused to install, neither from the CD or the downloadable executables on the website. After spending a good chunk of time researching possible fixes, we had to reinstall Windows from scratch, making sure to install AI Suite first before everything else.

In the BIOS section we pointed out the DirectKey feature that allows the reset button to be used to enter the BIOS directly on a cold boot. The Boot Setting utility provides similar functionality, restarting into the BIOS from convenience of the desktop.

Turbo LAN is another interesting applet that gives users the ability to conduct local traffic-shaping. Network priority levels can be set for a variety of applications and file protocols. This is particularly useful if you have a limited speed internet connection or use specific applications that demand better ping times for optimal performance (such as online games). If data caps are an issue, you can budget bandwidth and there’s also a charting function to help visualize your usage.

ASUS’ main utility, AI Suite, has undergone a bit of a revamp with all the major aspects like Fan Xpert bundled together in what they call “Dual Intelligent Processors 5.” At the top is a “5-Way Optimization” button that tweaks the settings in each main module (TPU, Fan Xpert, DIGI+Power Control, EPU) for optimal performance and energy efficiency. It automatically overclocks, changes voltages, tunes fans, selects appropriate power regulation settings, and tests for stability all simultaneously so you don’t have to deal with all the minutia. Each module can be tweaked individually of course, and at the bottom is a monitoring section which can display frequencies, voltages, temperatures, fan speeds, CPU utilization, etc. Turbo App is the only completely new section, a utility that lets users apply different performance settings to specific applications.

The TPU section is where a typical overclocker will spend most of their time. The same options as in UEFI BIOS are present but everything’s depicted in a more pleasing manner.

There are three different performance/power profiles that can be selected manually. If you decide not to overclock, the power saving profile is a quick way to save a bit of electricity with very little work. Essentially it works by undervolting the CPU, either with user defined values or automatically, though the automatic route obscures exactly what is being undervolted and by how much.

In automatic power saving mode we saw a power consumption reduction of between 2W and 5W with zero impact on GPU/CPU clock speeds, so these are essentially free efficiency gains. Any board with undervolting options is capable of saving a few watts here and there but ASUS makes it less of a hassle.

Fan Control

Fan Xpert 3 is of most interest to us, but it’s really not that different from the second iteration, though nevertheless impressive. It is more powerful but only because ASUS added new fan features to the board, not just the software, like enabling PWM control across the board, and allowing other temperature sensors to serve as the basis for fan control. Each fan can be labeled and assigned a case position (it’s easy to mix them up in multi-fan systems) and assigned their own individual profile.

After tuning the fans, Fan Xpert displays the controllable range and allows you to adjust the fan speed curve accordingly. You can also control how quickly the fans react at both ends, when speeding up and slowing down.

The Chassis fans have slightly different options than the CPU fan. The available spin up times are much longer so they react slower to temperature increases, and you can select a source, that is the sensor to which it responds.

AI Suite is almost a full screen application but it still doesn’t display as much as we want. The fan location schematics take up a lot of space so there isn’t enough room to show all five fans on the same screen, and system monitoring has been squished into the lower quarter of the screen. There’s a nice fan speed graphing option but it can only display three fans at a time and the scale is tiny.

FINAL THOUGHTS

From a feature perspective, the ASUS Z97-PRO’s primary focus seems to be storage. M.2 and SATA Express provides some future-proofing and an extra ASMedia controller supplements the standard SATA ports offered natively by the chipset. There are a total of eight SATA 6 Gbps ports available (six if you utilize M.2 or SATA Express), which is more than sufficient for the here and now. USB 3.0 is well-represented as well with four connectors at the back and four more available mid-board, again thanks to a supplementary ASMedia controller. The Z97-PRO’s 12 phase power is more efficient during heavy usage but this is somewhat balanced out by above average power consumption on light loads. The provided VRM heatsinks do their job well and both remained fairly cool even during load tests.

The UEFI BIOS has a great look and feel and is filled not only with good functionality, but little conveniences that makes life easier. If there’s one complaint, it’s that there are too many options to scroll through. The included software is of a similar vein, powerful, customizable, and perhaps overwhelming for the uninitiated. That being said, the less technically savvy user shouldn’t shy away, as all this tinkering is optional. You can always use ASUS’ various tuning features to do the heavy lifting for you. The only real issue we ran into during our entire time with the Z97-PRO was getting AI Suite up and running, which necessitated a full reinstall of Windows. We recommend installing AI Suite immediately, even before the drivers.

CPUs and GPUs are increasingly being cooled by AIO liquid coolers, which requires regulation of both a pump and one or two fans, making fan control more important than ever. The last generation of ASUS motherboards had excellent controls and this has only improved with the Z97 series. The Pro model has six fan headers, five of which are individually controllable with your choice of PWM or DC control. Furthermore, you can tie the fan speed curve of each fan to a different temperature, giving it a whole new dynamic. Front fans can be made to respond to the chipset temperature, top fans to the VRM temperature, or any other variation. If they had managed to tie in off-board temperature sensors such as hard drives and graphics cards, it would be close to perfect.

Overall the board is rock solid with a good feature-set, though it doesn’t really standout in this regard as there are numerous comparable boards in the same price-range. What really sets ASUS part are the extras and the Z97-PRO has this in spades. You don’t necessarily need to spend US$190 to get this experience either, as lower-tier models in ASUS’ Z97 line have similar functionality to varying degrees.

Our thanks to ASUS for the Z97-PRO motherboard sample.
