ASUS Sabertooth Z97 Mark S Limited Edition Motherboard Review

Add Your Comments

We’re still several months away from Intel’s next round of CPU/Chipset releases, but that’s not stopping ASUS from keeping the Z97 based motherboards an interesting lot. To that end, they recently released the Sabertooth Z97 Mark S Limited Edition motherboard. This niche product falls in ASUS’ TUF series motherboard line, and it features an arctic camouflage thermal cover resting on a white PCB. White PC components seem to be gaining in popularity, so it’s nice to have options if you like the white look. Specifications wise, the Sabertooth Z97 Mark S Limited Edition mirrors that of the Sabertooth Z97 Mark 1 we reviewed several months back. The Mark 1 had lots of great features and performed outstanding in all our tests, so let’s see if the Mark S can hold up its end of the bargain.

Specifications and Features

As we look at the specifications below (courtesy ASUS), we can see all the latest technologies are present and accounted for. There are lots of connectivity options via SATA, SATA-Express, USB, and at the rear I/O area. The motherboard conforms to the ATX form factor and comes with a 5-year warranty. Dual LAN ports and the Realtek ALC1150 CODEC are a couple other highlights here.

Moving on to the features, we’ll start with a motherboard overview showing several of the high-level features. All below images and descriptions courtesy ASUS.

The Thermal Armor provides many functions other than its aesthetic value. The included fans offer reversible fan technology to help keep things dust free, and the Thermal Armor housing has air flow valves to optimize its cooling effect for water or air CPU coolers. The picture below also shows the included dust covers installed in the PCI-E expansion slots, DIMM slots, and rear I/O area. There are plenty of these dust covers included in the kit to seal off any unused areas from dust accumulation.

A combination of form and function, Z97 Thermal Armor has been upgraded with innovative reversible-airflow technology that literally blows dust up and away from the heatsink and VRM!

By opening the two airflow valves, greater circulation can be achieved for air-cooling scenarios, while closing the valves will focus the airflow into the Thermal Armor channels — ideal for systems using self-contained liquid CPU coolers.

The TUF ICe processor built into the motherboard is said to provide precise temperature and fans speed monitoring, which makes any manual or software based cooling scheme you choose give the intended results.

ASUS TUF engineers have forged a brand-new microchip that delivers incredibly precise temperature monitoring and fan controls. With the TUF IC Cool processor, you can be assured that monitoring of onboard temperature sensors and fan speeds is always ultra-accurate — whether you’re adjusting settings manually or using the automatic one-click optimization.

The TUF Fortifier found on the back of the motherboard is a dual-purpose affair that provides motherboard rigidity and an additional layer of cooling.

TUF Fortifier adds a strong backplate so the motherboard doesn’t buckle under the weight of heavy graphics cards and CPU coolers. Reduced PCB bowing and bending means an end to potentially damaged circuitry. TUF Fortifier uses a thermal pad attached to the motherboard, making the whole backplate a huge heatsink that directs heat away from key components such as VRMs and MOSFETs. TUF Fortifier also protects DIY builders from solder pins and other sharp motherboard parts – preventing annoying cuts!
sabertooth_marks (5)

Some of the high-end components found on the motherboard are the 10K Ti-Caps, TUF Alloy Chokes, and TUF MOSFETs. The components are said to ensure cooler operation, longer lifespan, and better power efficiency.

Our military-grade alloy chokes have an 18.5%-larger heat-dissipation area so they run up to 13.6% cooler — and that means a longer lifespan for your PC. Unique Black Metallic capacitors with military-standard certification offer +20% high and low temperature tolerance and 5X longer lifetime usage. TUF MOSFETs also pass military-grade tests with lower RDS(on), certified for tough duty.
sabertooth_marks (6) sabertooth_marks (7)

Extended lifespan is also enhanced with the TUF ESD Guards. The ESD guards are supposedly tested to a 30% higher level than the industry standard.

Electrostatic discharge (ESD) can happen suddenly, and its damaging effects are easily underestimated. TUF ESD Guards are tested to standards that are 30% higher than industry standards, ensuring electrostatic discharges are properly grounded from all onboard connectivity — and that means greater component longevity.

The onboard audio solution incorporates shielding, motherboard isolation, and a different PCB layer for the left and right tracks. An audio amplifier and a de-pop circuit round out the features here.

TUF Audio Design makes short work of optimizing audio settings for the way you want to listen, chatting, watching movies or relaxing to your favorite music. Onboard physical shielding, professional engineered design and premium components result in sound output that has exceptional clarity and fidelity.
sabertooth_marks (9)

Another feature worth mentioning is the server-grading testing that’s performed on the TUF series motherboards. Obviously, that kind of testing is a big reason why these motherboards come with a full 5-year warranty.

Server-grade Tests – Systematically-tested stability

ASUS is proud to be a leading total solution provider. That means we test more than just the product itself — we examine system durability as a whole. Our motherboards undergo extreme temperature variations (thermal shock), extensive Mean Time Between Failure (MTBF) tests and many whole-build server-grade stability tests — so you know that your TUF motherboard can be trusted in all conditions.

There are many more features to explore as we take a closer look at the motherboard itself; but for now, let’s get the box on the workbench and have a look around.

Packaging/Accessories/First Look

The retail box holds true to the white camouflage theme and does a great job of explaining what you’re buying into. The box top has a nice TUF logo and several icons describing a few of the features, At the bottom, you’ll find greater detail on the motherboard’s features and specifications. The box sides are reserved for additional marketing and product branding.

With the box top open, we find a hard plastic cover for some of the accessories to rest in. Below that, the motherboard is found nicely wrapped in an anti-static bag. Below the motherboard is the last group of accessories. The accessory stack is pretty impressive and includes everything needed to get the motherboard installed. ASUS provides a full set of dust covers for any slot, port, or connection that’s not in use. Here is the list of included accessories.

The following slideshow provides pictures of the Sabertooth Z97 Mark S from various angles, which gives you a good idea of the design and looks of the motherboard. ASUS first showed this design at Computex 2014, where they say it was enthusiastically received as something people wanted to take home with them. Based on that feedback, ASUS decided to offer it in limited quantities.

The ASUS Sabertooth Z97 Mark S Up Close

In order to have a close-up look at the motherboard, we needed to remove the Thermal Armor and TUF Fortifier. Both pieces attach to each other with the motherboard sandwiched between. The TUF Fortifier has a thermal pad that makes contact with the underside of the MOSFETs. As you can see, the PCB is completely white. The two included fans are not preinstalled, so the end user will need to install them if desired.

At the bottom edge of the motherboard, you’ll find a host of connection points. Starting from the left, you have headers for the TPM, front panel audio, SPDIF out, and three thermal sensors. Moving over a bit, we find the Thunderbolt header, two 4-pin fan headers, and the first of two USB 3.0 front panel headers. To the far right are the two USB 2.0 front panel headers, two SATA 6 GB/s ports (ASMedia), and the headers for the case wiring.

Turn the corner and head up the right side of the motherboard, you’ll come to six more SATA 6 GB/s ports that are all native to the Z97 chipset. There is a SATA-Express port within that block as well. Just next to the SATA ports are the second USB 3.0 front panel header and the 24-pin ATX power connector. Higher up the right side of the motherboard is where the MemOK! button and the four DIMM slots are located. The MemOK! button can be used to automatically find memory settings that may allow incompatible memory to work or at least allow the system to boot. Just next to the MemOK! button, you’ll see a small LED marked “DRAM LED.” This LED will stay illuminated if the memory is keeping the system from booting. In fact, there are similar LEDs scattered about the motherboard for VGA, CPU, and boot device. The DIMM slots support up to 32 GB of DDR3 memory. While the printed specifications for the motherboard only mention support for memory speeds up to 1866 MHz, the ASUS QVL list shows memory has been tested to work up to 3200 MHz.

Down the left side of the motherboard are all the I/O connections. Here we have four USB 2.0 ports, the BIOS Flashback button, and the HDMI and DisplayPort connectors. Further down the line are two LAN ports (1 x Intel & 1 x Realtek), four USB 3.0 ports, and the audio jacks. The block of audio jacks also has an optical out port as well.

At the bottom of the motherboard’s left side is everything related to the onboard audio. You can easily see the isolation line running through the area and the audio amplifier. As we mentioned before, the audio solution is based off the Realtek ALC1150 CODEC.

The CPU socket area is pretty wide open for most air coolers on the market. With the TUF Armor in place, there could be potential issues with some AIO coolers if their hoses come into the CPU block from the side. Any custom water block where the hoses mount on top should easily fit.

The motherboard’s passive cooling solution includes a large heatsink over the PCH and a dual heatsink design covering the MOSFETs. Both the PCH and MOSFET heatsinks were found to be making excellent contact with their target points. To add additional air flow through the MOSFET heatsinks, it’s a good idea to install the two small fans included in the accessories. Once those are installed, you can utilize the adjustable air flow gates on the TUF Armor to better suit your needs.

With the board pretty much stripped at this point, we can see the 8+2 power phase design ASUS implemented here. The eight CPU power phases are handled by the all digital DIGI+ VRM controller. The DIGI+ VRM controller allows access to a host of power delivery options, as you’ll see when we tour the UEFI BIOS. The two power phases dedicated to the memory are handled by their own DIGI+ VRM as well. The 10K Ti capacitors, newly designed chokes, and MOSFETs are said to all be military grade components.

A removable BIOS chip is something we still like to see, just in case disaster strikes and it needs replacing. The Winbond 25Q64FVAI16 is used in this case. For Super I/O functions, ASUS uses the popular nuvoTon NCT6791D controller. The TUF ICe processor we discussed earlier is located just next to the audio components.

You may have noticed the lack of onboard power/reset buttons and a post code LED display. Other than that, a nice motherboard layout. Now that we’ve taken a close look at what the Sabertooth Z97 Mark S has to offer, let’s fire this thing up and have a look at the UEFI BIOS.

ASUS UEFI BIOS

ASUS has done a nice job making their EZ Mode area of the UEFI BIOS very user friendly. For the novice user, it’s a quick and painless way to to check on system vitals and setup basic system parameters. You can select the EZ Tuning Wizard where you’ll be presented with a few questions. Once answered, the wizard will automatically tune the system based on the answers you gave. There is also a RAID option that will guide you through setting up RAID arrays.

Pressing F7 will get you into the Advanced Mode where the more seasoned users will want to be. The first section is the My Favorites area where you can setup shortcuts to favorite UEFI BIOS pages. Across the top of every page in the UEFI BIOS are shortcuts to the My Favorites area, the EZ Tuning Wizard, Q-Fan Control, and Quick Notes. The Q-Fan Control lets you set fan speeds based on temperature thresholds, or you can configure them manually. Quick Notes gives you the ability to takes notes for quick access later. Think of it as Notepad for the UEFI BIOS.

Moving over to the Monitor section, you find just what the name implies. Here you can keep an eye on real time readings for temperatures, voltages, and fan speeds. One of the industry’s best set of fan control options built into a UEFI BIOS can be found in this section. You can choose from pre-configured settings or manually set things based off any of the available target source temperatures. There are also settings for the Dust De-Fan feature where you can set the duration between initiation and how long the fans will run in reverse rotation.

Bundled Software – AI Suite 3

The AI Suite 3 software bundled with the TUF series motherboards is a little different than what we typically see included with ASUS’ ROG and Channel series. The big difference is that Thermal Radar 2 takes the place of 4/5-Way Optimization. This makes sense because the TUF line of motherboards are geared more towards product longevity, which can be enhanced by a good overall cooling scheme. What this means for the overclocking crowd is you’ll have to go “old school” and use the UEFI BIOS to get your overclocking done. We’ll assume the vast majority of our readers overclock through the UEFI BIOS anyway, so this obviously isn’t a big deal.

With the software launched, the home screen has icons you can click to enter any of the utilities included in AI Suite 3. Thermal Radar 2 is the headliner here and offers thermal tuning, fan control, thermal status, a recorder, and several DIGI+ power control options. Thermal tuning is designed to test all fans hooked to a motherboard header and then produce profiles that will produce the best cooling with the lowest noise. There are nine temperatures sensors on the motherboard that you can choose as the target source for any fan. Additionally, the accessory stack comes with three thermocouple cables you can use as a target source as well, once hooked up the the appropriate header on the motherboard.

Other features of Thermal Radar 2 include the ability to identify where each fan is located inside your case. The software has the Dust De-Fan controls and Fan Overtime parameters available. There is a CPU cooling assessment tool that provides a Celsius per watt score based on the CPU thermal qualities. In our case, the assessment result was 0.57 °C/W, which is considered very good. ASUS even includes the ability to control the fan on your video card, as long as it’s a compatible ASUS brand card. Looking at the slideshow images below will give you a good idea of what all this looks like and how it functions.

For network management, an ASUS skinned version of cFOS software (Turbo LAN) can be found on the support DVD. The main page allows you to choose outgoing priority between VoIP, streaming, gaming, or file sharing. There is an additional advanced settings area that allows for a tremendous amount of network management options.

Our usual set of benchmarks are on tap today to test compression, rendering, video conversion, and memory performance. Just for fun, we’ll toss in some 2d benchmarks as well. We usually don’t see a whole lot of difference when comparing motherboards, especially when the same CPU, chipset, memory, and GPU are used. To that end, we’ll simply provide screenshots of the stock and overclocked benchmark results. This basically tells us if there are any performance issues the motherboard exhibits during the benchmark runs. We’ll spot check these results with other Z97 motherboards we’ve reviewed in the past to make sure everything is in line. During the stock testing, the CPU was locked down at the Turbo Mode speed of 4.4 GHz because of the ASUS Multi-Core enhancement built into the UEFI BIOS. We typically like to do stock testing at the CPU’s Turbo speed anyway, so no worries there. The memory was set to its XMP profile setting of 2400 MHz.

Using the UEFI BIOS to overclock, getting the CPU to 4.7 GHz was a rather simple procedure. By adding some voltage to the CPU, setting the LLC to a mid-range option, and manipulating a few power delivery options, we got the system completely stable at that speed. The UEFI BIOS was easy to work with during the overclocking adventure, and everything worked extremely well. With our overclock in place, let’s get to the benchmarks!

Some very nice benchmarks results were obtained as you can see above. After checking these results against previous Z97 motherboards reviewed, the performance is right where is should be. Let’s see if we can squeeze a little more out of it!

Pushing the Limits

By manipulating the strap to 125 BCLK, adding 1.5 V to the CPU, and dropping the memory speed down to 1666 MHz, we managed a suicide run of wPrime 32M and SuperP1 1M at 4.875 GHz. Not a shabby result, and it definitely shows the Sabertooth Z97 Mark S is a very capable overclocking motherboard.

Conclusion

The ASUS TUF Sabertooth Z97 Mark S is a very unique offering that should appeal to anyone looking to build a white-themed system. Regardless of the color though, it proved to be a great performing motherboard that provides many of the features enthusiast level users look for. System longevity, an abundance of cooling options, and server-type testing backed by a 5-year warranty are a few features that separate this motherboard from others on the market. Of course, the white TUF Armor and PCB add an additional layer of uniqueness that’s hard to find elsewhere. Dual LAN ports, SATA Express, and a good onboard audio solution should appeal to those looking for the latest onboard technologies. The overclocking crowd wasn’t forgotten either, and you’ll find everything you need in the UEFI BIOS to get the most from your system.

If we were to nitpick a couple things, we would like the TUF Armor to allow just a little more room around the CPU socket area to accommodate a wider range of coolers. Adding a post code LED display and onboard power/reset buttons would be nice to see as well, but that might just be the reviewer in us talking.

As far as pricing goes, Newegg currently sells this limited edition motherboard for $289, which means there is a $50 premium to pay over the TUF Sabertooth Z97 Mark 1. Being a niche color and with only a small amount of these being produced, it’s understandable why the $50 premium is there… When they’re gone, they’re gone.

With white-themed system builds becoming more popular, the Sabertooth Z97 Mark S Limited Edition should definitely be on your radar if a build like this is on your road map. There is no need to sacrifice features and performance to get the looks you want… Overclockers Approved!
