ASUS Sabertooth X99 review and test motherboard

This series includes boards on all chipsets, and AMD, and Intel, including, of course, X99. Actually, on top of the X99 is built and overlooked today motherboard ASUS Sabertooth X99.

ASUS Sabertooth X99: Packaging equipment

Let’s start with a review of the box. Aforesaid outwardly stylized shabby metal, and generally creates the impression of something serious. The size is pretty standard for top-end motherboards ASUS Sabertooth X99, but it is much heavier than the boxes of other boards.

But here is a kit you can actually call perfect. There is no such a very, very expensive the final cost (like wireless chargers, antennas, OC panel), but a lot of small, and inexpensive to manufacture, and cool/useful.

Shocking the number of different plugs. They are: for connector panel I/o, memory slots, expansion slots and even the SATA ports. But to him we shall return.

Total package:

  • Plugs for ports/slots
  • 40 mm fan
  • Three thermocouples
  • The cover on the rear panel (with insulation)
  • Adapters Q-Connector (for easy connect/disconnect buttons on the front panel)
  • Driver disk
  • Six SATA cables
  • Warranty and user manual
  • A certificate of completion of a series of stability tests
  • Two stickers (well, all stickers there, so you need to take)

A good set, you could even say enviable. Even the labels are. So for a box set exactly 5+.

ASUS Sabertooth X99: Appearance and features

First, upon inspection of the Board catches the eye is what? No, not that Board is not visible, and what is here for fans is, the attention, the nine (!) connectors. The majority of the boards 3, well 4 of the connector. On ASUS Sabertooth X99can be 5-6. But it is understandable, because the processors on the socket s2011-3 heated more than the Z170, and it suggests a more powerful cooling system. But 9 ports! On the other hand, such connectors are never enough=) and they do not spoil, because intelligently grouped: three on top, three on bottom, three on the side. Right next to each other.

Now we can speak about the cover. As you can see, it covers almost the entire surface of the Board. Some of his components from metal, some from plastic. According to the description, this cover is intended solely to protect the Board from mechanical damage. Do not heat it dissipates.

On the ports of the I / o plug, in the place where you can set the most complete 40-mm fan. It has some practical benefits, because under it there is a small radiator connected to the radiator for the CPU VRM area heat pipe.

On the reverse side of the motherboard ASUS Sabertooth X99 has another cover, but this is metal. In addition, here he is still engaged and the heat (there are thermal pads between the plate and the cost).

If you want the covers easy to remove, and then also easy to put in place, but without intruding the fee is starting to look absolutely typical. When removing even noble 5 year warranty will not be lost. By the way, there’s nothing newfangled lighting, and everything like that. “Honed” it to another.

And Yes, all these extra covers and the heatsinks are very heavier cost. It is unusually heavy. On the other hand, they stiffen the PCB, preventing the bending. And more importantly, in the presence of 8 slots for RAM, and so many other connectors, ASUS Sabertooth X99 will fit in a standard ATX form factor (size 305х244 mm).

As with all other motherboards based on X99 chipset, this model 8+2 phase power design (CPU+memory). Here, everything is on the highest level. Ultra-high-quality integrated assemblies manufactured by ON Semiconductor, Japanese-brand capacitors, and inductors, military-grade TUF Chokes. The latter is notable for its hull, which immediately and a mini-radiator. Extra power for all this is supplied via one 8-pin connector and one 4 pin. To use both at once is not required. Adding the additional 4-pin is meaningful only during extreme overclocking with LN2.

Special attention deserves the socket s2011-3. “Normal” so the socket will engage all of the contact Professor and special OC Socket has more pins. According to the manufacturer’s website, these additional contacts improve the overclocking potential of the CPU and memory speed, and increase the upper ceiling voltage up to 1,825 In (1,725). In most cases it’s not necessary, but professional overclockers rejoice, I guess.

ASUS engineers have implemented special slots DDR4. Here are 8 of them (supports up to 64 GB), and RAM fee accelerates over 3,200 MHz. Enhanced acceleration is achieved through a T-shaped fork in the slots, but and you should connect.

Full specifications of ASUS Sabetooth following:

There are M. 2 (and 32 GB/s, and it too is closed with a plug) and never gained popularity, SATA Express (10 Gbps), and, of course, very decent audio section based on codec Realtek ALC 1150. The sound tract was thorough. The left and right channels of audio are divorced, and are on different PCB layers. There is a separate amplifier, complete separation of analog and digital paths. What can I say, just behind the audio jacks are already capacitors.

Separately among all this is to provide a COM port. “Old man” appeared in far, far 1969, almost 50 years ago, and now almost never used. ASUS, seriously? The serial port in one of the top boards for $300?

  • Panel I / o is:
  • 4хUSB 2.0
  • Special USB port for TUF Detective
  • Button reset BIOS
  • 2xUSB 3.1 (10 Gbps)
  • 4xUSB 3.0
  • 2xEthernet ports
  • The audio outputs and optical S/PDIF

The port of TUF Detective is a very cool trick. You can connect your phone, download the app (on Android and on iOS), and then from your phone you can not only monitor the status of the computer, but also POST-codes to understand why the Board suddenly does not start. You can still enable/disable/restart the computer. Thus the absence of such buttons, and a separate indicator for POST codes on the Board itself is smoothed.

About myself I want to add that everything was done very efficiently. There’s no plastic latches, all strictly on screws, including radiators VRM design. Yes, little things, but that is indicative of a sensitive approach.

Often when looking at an “eye” already immediately obvious where saved. So, in the ASUS Sabertooth X99 is never saved.

ASUS Sabertooth X99: BIOS settings

If the BIOS functions to stay separately, we will not, and at the end of the chapters will be shown only screenshots of the main sections, it’s about software Thermal Radar 2 tell worth.

So, Thermal Radar 2 is a utility that allows real-time tracking of the indications of the system.

On the Board itself in many places are equipped with heat sensors, and three more can be done by thermocouples, which are supplied. But the main feature is not that. At the touch of a button, the motherboard automatically adjusts the fan speed to achieve the optimal temperature at each node.

Also, if the system uses a graphics card made by ASUS, the fee begins to adjust the cooling of the graphics card (if the appropriate option to turn of course).

ASUS Sabertooth X99 review and test motherboard

All this is a cool design, very convenient and clear. There is even a rating cooling, and readings of the load on the power phases!

Of course, Thermal Radar 2 is able to monitor the CPU load, the temperature not only on the MB sensor, but embedded in the CPU, drives, etc.

In General, it is a fully integrated, through which you can manage the entire system, and track performance.

BIOS, in General, like all other expensive ASUS motherboards. The only difference in the design, and everything is as usual.

Stand, overclocking and testing

Surveys the Board was tested with the following set of components:

  • CPU: Intel Core i7-6900K (4 GHz);
  • Cooler: Noctua NH-D15S;
  • Motherboard: ASUS Sabertooth X99 and other;
  • RAM: GeIL Dragon Ram DDR4-40008 GB (2×4 GB)
  • System drive: Kingston M. 2 480 GB;
  • Video card: ASUS GeForce GTX 1060 Strix6 GB;
  • Bench: DimasTech BenchTable Extreme;
  • Power supply: Thermaltake DPS G RGB850 W;
  • Operating system: Windows 10 x64.

It is worth noting that the processors Broadwell-E, which includes our Core i7-6900K, appears only after updating the BIOS to the latest version.

The tests for later, but first, a little about overclocking. C default frequency 3.2 GHz, the Professor managed to rally to raise to 4 GHz, which is the first slat. 4 GHz will take almost any fee.

ASUS Sabertooth X99 review and test motherboard

We went ahead and 4200 MHz were also taken. By the way, charge up to 4.2 GHz able to overclock the CPU itself, in the mode of TPU II, which was activated in the BIOS. However, 4.2 GHz only on one core, the frequency of all the rest was about 4050 MHz. 4200 MHz is a kind of threshold that is crossed only good Board.

Of the many tests I have found that our copy of the Intel Core i7-6900K is able to accelerate to 4.5 GHz, but only with very good cooling. Not LN2 of course, but expensive dropsy for sure. In fact, if 4.5 GHz is taken – then the motherboard is the top level.And, of course, of course, the difference in overclocking under liquid nitrogen with any other Board would, but for “water and air” for 4.5-4.6 GHz ceiling.

Now about the tests. As usual, the boards on the same chipset with the same CPU and all other test results are always extremely similar. The difference is only 1-2% is not significant, and may even lead to mathematical error. Therefore, the indicators will be given only in a pair of the popular utilities, and a couple popular games. Whether it is comparing several different chipsets out there has the meaning of a large set of tests here and everything is clear.

Here one screenshot is enough. The results of the boards are identical.

As expected, the difference in synthetic benchmarks is minimal. All the boards are good, and the difference in performance is within 1%.

Completely identical situation in the games. And in DX12 and DX11 games in 1920×1080, and 2560х1044.

ASUS Sabertooth X99: Conclusion

ASUS Sabertooth X99 is, no doubt, cost the top level. If only other such “motherboard” is very beautiful, backlit and so on, overlooked fee is quite different. As was said in the beginning of the review, in the first place put forward was the reliability.What caused it is not only the highest quality components, but also the potential for cooling.

Not every card has a whopping 9 connectors for fans, and active fan to cool the VRM, which can be removed. Also not to mention the excellent software Thermal Radar 2 that optimizes the fan speed at only 1 click.

The plugs for the slots/connectors/ports is actually a great thing. They protect the connectors from dust and anyone who has ever “to Shine” out of the system after long months of work, faced with the fact that 1 time it doesn’t start. After purging the connectors are all back to normal. The plugs will prevent this. It’s great.

  • Price

From the obvious drawbacks, is to provide only the price. If the most unpretentious X99-Board you can buy for $170, and more or less decent cost from $220, for ASUS Sabertooth X99 asking $300. But here at least is clear and weight is felt that for the money paid.
