I'm sorry if it looked rough, I do not want to offend.
Thank you for your time.

No need getting huffy with us. We're Moderators, and while very experienced with what we discuss we're not the smart folks who designed it.

Of course not.
Theoretical and actual is not the same thing.

Exactly. It's absolutely not confirm anything.

In general, I would ask you if you believe that any USB revision, such as 2.0 or 3.0, on any board, provides the full theoretical speed in actual use.

I don't know where that Russian website got that diagram of the X99 chipset connections to the various IO devices. It is true that the PCIe lanes from the X99 chipset are PCIe 2.0, which would be the same for any mother board. Unfortunately, they don't show that one SATA port is normally implemented with two PCIe 2.0 lanes. They also don't show the multiplexing chips that are used to connect multiple PCIe 2.0 lanes to an IO device, that are used on the X99 Taichi board.

We know the real world maximum speed of a SATA III SSD on a SATA III port, for large file sequential read speed is ~550MB/s. This is the result of testing the X99 Taichi's USB 3.1 port in another review:



https://www.techpowerup.com/reviews/ASRock/X99_Taichi/11.html

The Marvell and ASMedia "SATA III" chipsets that are designed to be connected to one PCIe 2.0 lane, will not produce sequential read speeds beyond 400MB/s with a SATA III SSD. USB of course does not have the advantages of the SATA interface, such as NCQ provided by AHCI, so will always be slower than an equivalent bandwidth connection.

The only current PC chipset that has PCIe 3.0 lanes is the Intel Z170 (called DMI 3 by Intel), and will be used in future Intel chipsets.

This does not prove or disprove the claim of the Russian website, but is a demonstration of the actual capabilities of USB 3.1 on X99 and Z170 chipset boards. Given the test above, the Z170 boards have no advantage over X99 boards in USB 3.0 performance.

Currently, since none of the CPU/chipset manufactures (AMD, Intel) provide native USB 3.1 support, it is common for mother board manufactures to provide add on cards for USB 3.1 support. ASRock includes PCIe cards like that with some of their X99 boards, but not at the price point of the X99 Taichi.

Gen2x1 would present a theoretical 4Gbit/s transfer rate. No where near 3.1 speeds.

Do you already have this board? Or considering buying one?

The fact that claims to support ASM1142 Gen2x2 or Gen3x1
Still does not mean that it can not work on Gen2x1 (with the consequent drop in bandwidth)

Or I'm wrong?

Ok, why do I ask?

Here is an overview X99 Taichi (translation needed from Russian) 
http://www.ixbt.com/mainboard/asrock/asrock-x99-taichi.shtml

The reviewers concluded that ASM1142 not connected optimally and using only Gen2x1.
And because USB 3.1 is actually obtained with low bandwidth

iXBT - rather authoritative resource.
I would like to have a clear understanding, it is just a mistake of those who have tested or really ASM1142 uses only Gen2x1 on this motherboard.

Hi

Question about X99 Taichi / X99 Professional Gaming i7 motherboards
How many PCI-E 2.0 lines is used to connect ASMedia ASM1142 (USB 3.1 Gen2)

1xPCI-E 2.0
or
2xPCI-E 2.0
