Our first ASRock X299 motherboard review is here, and today we will look at the X299 Taichi. The Taichi brand has been one ASRock has offered since they launched their X99 Taichi last year. The whole concept of the Taichi is balance and in this case a balance of price and features. The motherboards have always been solid, but never over the top or of lower quality than one might expect from a high-end motherboard.

The aesthetics of the motherboard also have not changed too much, the ying and yang white and black theme has moved over to silver and black, and ASRock has done much more to clean up the PCB to improve overall looks. Many of the motherboard's components can be found on the rear of the board. Let's see how this more affordable X299 motherboard does!

Specifications

The X299 Taichi offers a lot of features including dual Intel LAN, three 32Gb/s M.2 slots, 10 SATA ports, a healthy amount of USB 3.0 and 3.1, and even WIFI.

Pricing

The X299 Taichi costs $289.99.

Packaging and X299 Taichi Overview

Packaging and Overview

ASRock X299 Taichi Motherboard Review 03 | TweakTown.comASRock X299 Taichi Motherboard Review 04 | TweakTown.com

Box and packaging are similar to what I have seen before from other ASRock's HEDT Taichi boards (mainly the X99 Taichi). The motherboard is well protected and zip tied into a foam tray, which is inside an anti-static bag.

ASRock X299 Taichi Motherboard Review 05 | TweakTown.com

The accessory package includes four SATA6Gb/s cables, two WIFI Antenna, IO shield, SLI HB bridge, 3-way SLI bridge, case badge, manuals, post card, and driver DVD.

ASRock put five fan headers on the X299 Taichi, all of them are 4-pin hybrid DC/PWM mode headers. All of them but the CPU fan header circled in red can auto detect whether a DC or PWM fan is in use. The CPU fan header supports 1A, while the two headers circled in blue over 1.5A of output. I am not sure of the current capabilities of the headers circled in green, but I would assume a minimum of 1A. The back of the motherboard has a ton of components, including the majority of the PCI-E quick switches.

ASRock X299 Taichi Motherboard Review 08 | TweakTown.com

The IO shield offers two USB 2.0 ports, four USB 3.0 ports, PS/2 keyboard/mouse port, WIFI antenna connectors, BIOS Flash Back button, Clear CMOS button, two 1Gbit Intel LAN ports, USB 3.1 type-A, USB 3.1 type-C, and gold plated 7.1 audio jacks with S/PDIF out.

ASRock X299 Taichi Motherboard Review 09 | TweakTown.comASRock X299 Taichi Motherboard Review 10 | TweakTown.com

The PCI-E lane allotment isn't straightforward, so I will list the speeds according to PCI-E slots PCIE1/PCIE2/PCIE3/PCIE5 as per the manual. With a 44 lane CPU you get x16/x8/x16/x0 or x8/x8/x16/x8, with 28 lanes you get x16/x0/x8/x0 or x8/x0/x8/x8, and with 16 lanes you get x16/x0/x0/x0 or x8/x0/x4/x0. That means that the 16 lane CPUs won't support SLI, only CrossFireX.

The three 32Gb/s M.2 slots all have one link to SATA ports 0,1, and 7, the manual will tell you which are shared. The M2_1 slot gets its bandwidth from the CPU, so with a 16 lane CPU, you will have to run your GPU at x8 if you want to use the slot. The 28 and 44 lane CPUs don't use PCI-E layout lanes if you use M2_1.

ASRock X299 Taichi Motherboard Review 11 | TweakTown.comASRock X299 Taichi Motherboard Review 12 | TweakTown.com

There are ten SATA6Gb/s ports, two of them are from ASMedia, and ports 0,1, and 7 share with M.2 slots if a SATA based M.2 drive is used. There is one right angled USB 3.0 header and one straight angled USB 3.0 header, both get their bandwidth from an ASMedia USB 3.0 hub.

ASRock X299 Taichi Motherboard Review 13 | TweakTown.comASRock X299 Taichi Motherboard Review 14 | TweakTown.com

An RGB header is located at the top right corner of the motherboard. In the lower right corner of the motherboard is a POST code display.

ASRock X299 Taichi Motherboard Review 15 | TweakTown.comASRock X299 Taichi Motherboard Review 16 | TweakTown.com

There are two USB 2.0 headers located along the bottom edge along with a ThunderBolt 3 GPIO header. An RGB LED header can also be found on this lower edge. The VROC header is located near the CPU socket.

The X299 Taichi really is quite beautiful.

ASRock X299 Taichi Motherboard Review 19 | TweakTown.com

The CPU VRM is in a 12+1 phase configuration and uses very high-end components both on the switching and filter side of things. ASRock has used Intersil's first fully digital solution, so let's see what they got.

ASRock X299 Taichi Motherboard Review 20 | TweakTown.comASRock X299 Taichi Motherboard Review 21 | TweakTown.com

There are three Intersil ISL69138 fully-digital PWMs, a first from Intersil. They were designed to be X+Y = 7 total PWMs, so you can use them in any configuration where two rails max out at seven total PWM channels. So you could use one ISL69128 PWM in a 6+1 phase configuration and another at 3+3 phases, for example, the new PWM also works very well with Intersil's brand new fully-integrated Smart Power Stage (SPS). The Smart Power Stage used here is the ISL99227B and ISL99227F, the only difference is the PWM input voltage range.

These Smart Power Stages offer a higher level of integration, better current sensing, and more protection compared to previous DrMOS implementations. Basically, these new parts can better react to large load swings and offer higher efficiency. They are a direct competitor to International Rectifier's IR3555, both are rated 60A, but these offer an almost integrated heat spreader. The new PWM and SPS offer direct competition to IR's solutions and should prove to perform quite well.

ASRock X299 Taichi Motherboard Review 22 | TweakTown.comASRock X299 Taichi Motherboard Review 23 | TweakTown.com

To get 12 phases from the six the PWM provides, ASRock uses a bunch of ISL6617 phase doublers on the rear of the motherboard. Here we find another ISL69138, most likely used to control the memory controller, and it controls two Sinopower SM7341EH dual N-channel MOSFETs.

ASRock X299 Taichi Motherboard Review 24 | TweakTown.comASRock X299 Taichi Motherboard Review 25 | TweakTown.com

We find two more Sinopower SM7341EH on the other side of the motherboard that power the other four DIMMs. On the back of the left of the motherboard carries a third ISL69138 PWM, and we can see two ISL6596 integrated drivers that drive the memory VRM phases.

The audio hardware on this motherboard consists of the Realtek ALC1220 codec along with a Texas Instruments NE5532 amplifier. Gold series audio capacitors and physical PCB isolation help to improve overall audio signal quality.

ASRock X299 Taichi Motherboard Review 27 | TweakTown.comASRock X299 Taichi Motherboard Review 28 | TweakTown.com

Intel's i211AT and i219v are used to provide dual Intel Gbit LAN on the rear IO. The i211AT is a standalone controller while the i219v is a PHY is requires the integrated MAC in the PCH to become whole.

Intel's Wireless AC 3168NGW is a 1x1 433Mbps Wireless AC card, and it also offers Bluetooth. It's not as fast as 867Mbps 2x2 WIFI cards, but it does get the job done if you need internet connectivity. USB 3.1 comes from the new ASMedia ASM3142 USB 3.1 controller that uses two PCI-E 3.0 lanes along with an ASMedia ASM1543 type-C switch and controller chip.

ASRock X299 Taichi Motherboard Review 31 | TweakTown.comASRock X299 Taichi Motherboard Review 32 | TweakTown.com

An ASMedia ASM1074 USB 3.0 hub provides both the internal headers with the bandwidth of a single USB 3.0 link from the PCH. An ASMedia ASM1061 provides two extra SATA6Gb/s ports, for a total of ten.

ASRock X299 Taichi Motherboard Review 33 | TweakTown.comASRock X299 Taichi Motherboard Review 34 | TweakTown.com

ASRock has a custom Flash Back chip, which I assume is similar to ASUS's "BIOS" chip in that it provides USB BIOS recovery from a file on a USB stick inserted into a specific USB port on the rear IO. The ASmedia ASM1184e provides four PCI-E ports from just one. I assume it outputs to the PCI-E x1 slot, WIFI card, and ASM1061.

ASRock X299 Taichi Motherboard Review 35 | TweakTown.comASRock X299 Taichi Motherboard Review 36 | TweakTown.com

The nuvoton NCT6791D is the main superior. The nuvoton N76E885 is used as a microcontroller that provides extra features such as RGB LED support; I found the same IC on ASRock Z270 motherboards with RGB LED features.

ASRock X299 Taichi Motherboard Review 37 | TweakTown.comASRock X299 Taichi Motherboard Review 38 | TweakTown.com

The ICS 6V41742B is used as the clock generator on the motherboard; it enhances BCLK overclocking margins. All of these PCI-E quick switches and bus switches help to shift around a very confusing PCI-E lane arrangement, at least ASRock moved them to the back of the motherboard, so they don't interfere with the overall look of the product.

BIOS and Software

BIOS

ASRock X299 Taichi Motherboard Review 39 | TweakTown.com

ASRock's X299 UEFI is very similar to that of their Z270 motherboards. There is both an Easy Mode and an Advanced Mode for those of you with more experience. There is an overabundance of overclocking settings for those who want to tweak everything to the maximum.

For the rest, there are simple preset overclocking profiles for the 7900X. I assume these profiles change when you use a different CPU. Fan control is also present through both a graph and a menu, making ASRock one of a few vendors to offer both options in the UEFI. RGB LED control is also present in the UEFI.

Test System Setup

Steven's Motherboard Test System Specifications

The X299 Taichi leans towards the RGB-less camp. While it does have some RGB LEDs built into the motherboard under the PCH, but they aren't that pronounced.

ASRock X299 Taichi Motherboard Review 66 | TweakTown.comASRock X299 Taichi Motherboard Review 67 | TweakTown.com

There are a few RGB LED headers on the motherboard if you want to light up the system. Overall, many people would rather trade RGB LEDs for more features, and perhaps the lack of RGB LEDs has helped position the X299 Taichi at an affordable price point.

Overclocking

Overclocking Results

CPU Overclocking

ASRock X299 Taichi Motherboard Review 68 | TweakTown.comASRock X299 Taichi Motherboard Review 69 | TweakTown.com

For the time being, I was testing how each motherboard can overclock the CPU and what settings to change to get a 4.6GHz overclock using AVX with XMP enabled. While finding where to change voltages might be a bit tricky as the CPU voltages are located inside different menus (Input Voltage in CPU menu while VCore is in the FIVR menu), overclocking the CPU was straight forward.

The new VRM components and the digital nature of Intersil's new PWM don't require too much enhancement of power settings to avoid throttling. Temperatures also stayed pretty low on the CPU, at least compared to some other motherboards.

Memory Overclocking

As you can see above, this kit runs fine with XMP on the X299 Taichi.

The ASRock X299 Taichi is a solid performer, and it was also benchmarked with the latest benchmarks and updated drivers along with the X299 Aorus Gaming 7. The other boards were tested right after launch and these two others last week, so we can see how things have gotten slightly better (in regards to mainly single threaded performance). You generally don't get more CPU, GPU, or memory performance out of a more expensive motherboard, you just expect them to be at the top of the charts, and the X299 Taichi keeps up with the much more expensive motherboards.

I don't too much too much credence into benchmarking the CPU or GPU to see how well the motherboard does, as the difference is almost always within the margin of error. These tests are to make sure performance isn't below that margin, or to see what's going on if it's above.

ASRock's X299 Taichi is one of the best-performing motherboards when it comes to IO performance. We expect as much from ASRock, who is known for their strong IO performance.

Audio RMAA 5.5:

I disable all audio features, set the correct bitrates, and then test the audio with a loopback test.

ASRock X299 Taichi Motherboard Review 83 | TweakTown.com

Sound Judgment by Ear: Excellent, the motherboard uses the ALC1220 without too much enhancement, so we have heard similar implementations and they should great. There are five ratings for audio: 1. Problems, 2. Okay, 3. Acceptable, 4. Very good, 5. Excellent

VRM and System Thermal Imaging and Power Consumption

Thermal Imaging and Power Consumption

System power is measured at the wall with an AC power meter.

ASRock X299 Taichi Motherboard Review 84 | TweakTown.com

Note on Thermal Images: In the temperature section, we use our Seek thermal imaging camera to capture the surface temperatures of major components on the board. I look at the VRM and then all other things that light up the screen. If there is something to worry about, then I will state it. Otherwise, I will just show the hotter running parts of the board for fun. Unless some component is over 80-90C, then there isn't anything to worry about.

All systems will act differently, so I will look for commonalities, such as how far from the VRM the heat spreads through the PCB and the difference in temperature between the front side and backside of the PCB. Keep in mind, the majority of the heat from the VRM goes into the PCB as it is a giant soldered on copper heat sink. A larger difference in temperature between the back and front of the PCB points towards a more effective heat sink.

Thermal Testing at Stock Speeds:

The image on the left is always at idle, and the image on the right is at load. During ALL TESTS, fans above the VRM that cool the CPU cooler's (Corsair H110i) radiator are turned on to high (12v).

The VRM thermal imaging here reveals a lot about how Intersil's new PWM works. For light load, it only turns one a single phase, but when full load is applied at stock, it seems to load balance on the left side instead of evenly balancing all the phases. It could be that the airflow is cooling those other phases, but we don't see this thermal gradient on other motherboards.

The VRM must have much higher potential, so the PWM puts more load on half of its phases. It is not a new approach, but until now with the integrated smart power stages, the real-time current balancing mode makes it safer.

4.6GHz 1.75V VCCIN OCed VRM Thermal Imaging:

ASRock X299 Taichi Motherboard Review 91 | TweakTown.comASRock X299 Taichi Motherboard Review 92 | TweakTown.com

Here with the 4.6GHz overclock, the PWM engages all PWM phases, or at least more. The VRM here is surprising. For starters, it keeps up with IR based solutions; Intersil is like the AMD comeback kid when it comes to high-performance digital VRM designs.

While the board has a single 8-pin connector for CPU power, it doesn't seem to be overstrained, and we should be pulling upwards of 300W, and there isn't throttling at 4.6GHz. The most impressive part is that the rear of the VRM is cooler than the front.

What's Hot, What's Not & Final Thoughts

Here are key points about the ASRock X299 Taichi.

What's Hot

Surprising VRM: ASRock is using what Intersil calls their first generation of fully digital PWMs along with their high-performance smart power stages. After doing some research, it does seem Intersil has hit the nail on the head and provided a very strong VRM solution for Intel's latest VRD13 specification. With the digital controller and smart power stages, the VRM keeps itself from throttling as it precisely knows the temperature and current of each power stage, which the PWM watches and then uses to balance out power regulation tasks. The VRM heat sink is surprisingly adequate as well, the temperature on the rear of the motherboard somehow stayed cooler than the front although it is not a very impressive VRM.

Triple Ultra M.2: The motherboard offers three M.2 slots, which as we all know is the latest on the consumer side of things when it comes to high-speed NAND and Optane based SSDs. The slot form factor is the best you can currently get as it can transform into U.2 if needed. Each slot offers 32Gb/s of bandwidth.

Dual Intel LAN: Need two Intel NICs? The X299 Taichi delivers that and even an Intel Wireless AC adapter. In this day and age when a 1Gbit NIC might not be enough for even home networking, being able to double your connection to the router or switch is a valuable thing.

Affordable: At this point, many of the X299 motherboards we see on the market cost over $300. They are premium motherboards with a price tag to reflect it, but so is the Taichi. The Taichi hits that sweet spot in the price to performance arena.

What's Not

Wireless AC is 1x1: ASRock has been using the same 1x1 Wireless AC controller, which means it doesn't offer up to 866Mbps, but instead 433Mbps, so if you do have a super-fast router and can take advantage, then you might want a faster card.

16 Lane CPUs Don't Get SLI: Because of the way Intel has routed PCI-E lanes, you won't be able to run 2-way SLI with a 16 lane CPU as you are limited to x8/x0/x4/x0 when something is inserted into the third PCI-E slot.

Final Thoughts

ASRock has done a fine job with the X299 Taichi. We could nitpick about only having an 8+4 pin power connector and single designer VRM heat sink, but the Taichi isn't a ROG motherboard. It is at the core of ASRock's design philosophy and has a long legacy of catering to power users, workstation builders, and gamers alike. Quality also is top notch on this Taichi series motherboard.

ASRock X299 Taichi Motherboard Review 93 | TweakTown.com

It is a do-everything motherboard, with just enough of everything to make everyone happy. Digital RGB LED support, Thunderbolt 3, best in class VRM components, and Wireless AD all find a home within the X299 Taichi. It's like the Swiss Army knife of ASRock's X299 offerings, and while it does cost a lot, it has the features to back it up.

If you are looking for a feature packed X299 motherboard and have a bit of change to spare, then the X299 Taichi might be the right motherboard for you.
