ASRock TRX40 Taichi
With ASRock announcing just two new models for the launch of the AMD Ryzen Threadripper 3970X and 3960X launch, it is no surprise to see one of its most predominant series hit the TRX40 chipset. The ASRock TRX40 Taichi takes its usual unique approach to aesthetics with its cogwheel inspired branding, and even adds integrated RGBs to further adds to its appeal. The most notable features include support for DDR4-4666 memory, a 16-phase power delivery for the CPU, and a Realtek 2.5 GbE controller.
The ATX sized ASRock TRX40 Taichi continues the unique lineage of models with a recognisable aesthetic with cogwheels implemented into the design, as well as integrated RGB LEDs into the chipset heatsink and the right-hand side of the board. Underneath the large aluminium heatsink is a 16-phase power delivery with 16 ISL99390 90 A power stages and is controlled by an ISL69247 controller running at 8+0. There are three full-length PCIe 4.0 x16 slots, with a single PCIe 4.0 x1 slot in the middle, which are surrounded by a black Taichi designed armor shielding around the PCIe slot area. For storage, there are two PCIe 4.0 x4 M.2 slots onboard with heatsinks integrated into the armor, and a total of eight SATA ports which support RAID 0, 1, and 10 arrays. Two of the SATA ports are straight angled and are located right next to the two-digit LED debug, power button, and reset switch.
Users looking to expand on the two PCIe 4.0 x4 M.2 slots will appreciate the Hyper Quad M.2 card in the accessories bundle which allows users to install a further four PCIe 4.0 x4 M.2 slots into one of the full-length PCIe 4.0 x16 slots. The ASRock TRX40 also has eight memory slots which support up to DDR4-4666 and 256 GB of memory. As with all launch day TRX40 models, the chipset heatsink has a cooling fan which is open and not covered by a grill, while there are five 4-pin headers with one for a CPU fan, one for a water pump, and three for chassis fans.
On the rear panel is two USB 3.1 G2 Type-A, four USB 3.1 G1 Type-A, and one USB 3.2 G2 Type-C 20 Gbps port, with a BIOS flashback button and PS/2 combo port. The five 3.5 mm audio jacks and S/PDIF are handled by a Realtek ALC1220 and ALC4050H audio codec combination, while the two Ethernet ports are powered by a Realtek RTL8125-AG 2.5 GbE and Intel I211-AT Gigabit controller. The board also includes an Intel AX200 Wi-Fi 6 wireless interface which also adds BT 5.0 connectivity.
The ASRock TRX40 Taichi is the premier board for enthusiasts in its line-up with each of the four full-length PCIe 4.0 slots supporting x16 across the board, which allows for a powerful gaming system, solid workstation, or for other tasks such as content creation. The ASRock TRX40 Taichi has an MSRP of $499 which represents good value for money based on the features and leaves the door open for an even more premium flagship further down the line.

I wish those boards had more Type C ports and dropped some of those A ports. A type C port can easily be turned in an A, but vice versa is against the spec.Also serious question: what is the reason to keep A 2.0 ports around? Are there any devices that don’t work on modern ports?

Probably much easier to route one old and slow data pair vs 1-4 high speed data pairs.I have many devices that will likely never need more than USB 2.0 - my Mouse and KB included. USB microphone as well. The best external device I've got that benefits from USB3 speeds is my Bluray burner, and we all know how popular those are. External USB flash drives are usually limited by the cheap NAND inside, and most of my external storage is on my network.
For others, I suppose USB capture cards? Really decent USB 3.0 flash drives? Even if I connected my phone to my PC, it's still limited to USB 2.0. Maybe a decent external card reader? These boards reviewed here are all ATX, so I'll rule out USB NICs. I've got to be missing something in my list.

There is still the odd device that doesn't work on USB 3.0. Also the last 2 machines I've built did not have fully functioning USB 3.0/3.1 ports in Linux, indicating lack of driver support for operating systems other than Linux. In short: USB 3.x is still a WIP despite being out on the market for quite a while.Llawehtdliub - Saturday, November 30, 2019 - link
Plz no. Dont do an Apple. Just beczus you cant think of a reason to use doesnt mean others cant.There is a reason to leave them.

Bring back PS/2 ports too? /sasmian - Thursday, November 28, 2019 - link
I'm a little confused by comments on the X570 boards that will probably apply to these also. With these new PCIe4 slots (and M.2 slots), is it the case that they are all completely independent and you can mix/match PCIe2/PCIe3/PCIe4 cards/drives freely at each one's maximum possible negotiated link speed? Or will putting (say) a PCIe2 RAID controller in any slot reduce all slots to the lowest common denominator, PCIe2 speed?voicequal - Thursday, November 28, 2019 - link
PCIe lanes are wired directly to the PCIe controller on either the CPU or chipset, so link speeds between slots are independent. PCIe 4.0 is backward compatible with previous generations 3.0, 2.0 & 1.0, so running a PCIe 2.0 card in a slot capable of 4.0 will run at 2.0 speeds and not affect adjacent lanes on other slots.Some motherboards allow you to reduce the maximum speed of PCIe lanes from 4.0 to something lower -- this can help to troubleshoot signal integrity issues. This setting sometimes does affect lanes across multiple slots. But as long as you leave it to Auto, the lanes will run at the highest compatible speed between card and controller.

Yes, in most cases the slots auto-configure to the device connected. Gen 3 devices should happily coexist with Gen 4 devices with each running at spec. In the case of the GPU, you can run it at Gen 3 if you prefer even if it is a Gen 4 GPU natively--there's separate switch for that in the bios, but the slots auto-configure for other devices and the GPU bios switch doesn't affect any other slots.I was surprised to see that several of the mboards had no rear clear-CMOS button on their backplates, and thought that was an interesting omission from the article--and the article also failed to mention dual-bios mboards--which the GB Aorus Xtreme & Master have (pictured mechanical switches) --one would hope they all might have them. Seems as if both these important features would be worth a mention...

Is there any downsides of going to PCIe 4.0? Maybe something similar to DDR3 and DDR4 memory where the bandwidth increases, but the latency goes up too?PopinFRESH007 - Sunday, December 29, 2019 - link
not really no
