The dock is not a simple splitter/passthrough device, it has it's own firmware and
additional hardware. From what you are saying the dock seems to be having compatibility
issues with your system.

There is quite a long list of common issues with your dock listed here.

I sympathize, based on what you have said in your posts I can only assume you are
navigating a dual ecosystem where you are trying to utilize mac and windows devices
together. This has been problematic since the beginning.

See what ASRock says when they reply your ticket. If nothing useful you may need
to look at getting a TB5 add in card for your system. Most windows users don't
use docks, that is more of a mac thing so as a result, not many motherboard manufacturers
put any effort into supporting them. ASRock does have a TB4 add in card if TB5
is not critical for you, otherwise things get expensive. As far as I am aware
ASUS and Gigabyte TB5 cards won't work due to proprietary headers being required.

It's always difficult troubleshooting things like this, essentially you are
troubleshooting 2 devices with no idea which one is causing the issue. Mac
TB implementation is not the same as PC, even within PC, laptop TB implementation
differs to desktop TB implementation. This is one of the primary reasons I used
to encourage clients to use a single ecosystem for their IT needs, compatibility
between Mac and PC has always been an issue, Apple likes to keep people on their
ecosystems and as a result tend to deliberately make compatibility problematic.
The advantage is that compatibility within their ecosystem is second to none
where PC users often suffer compatibility issues even within the same ecosystem.

Sorry I couldn't offer more useful assistance. ]]> Sat, 19 Sep 2026 14:42:06 +0000 https://forum.asrock.com/forum_posts.asp?TID=113583&PID=202038&title=x670e-taichi-carrara-tb-usb4-enumeration#202038 https://forum.asrock.com/forum_posts.asp?TID=113583&PID=202037&title=x670e-taichi-carrara-tb-usb4-enumeration#202037 Author: abhisheksrinivas

So the weird part is the port works when any single device is connected like an SSD or a USB but the same doesn't work if a dock is connected]]> Sat, 19 Sep 2026 13:44:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=113583&PID=202037&title=x670e-taichi-carrara-tb-usb4-enumeration#202037 https://forum.asrock.com/forum_posts.asp?TID=113580&PID=202035&title=x870e-taichi-lite-no-post-with-a2-b2-ram#202035 Author: Xaltar

Thanks for the additional info Assi.

It may well be worth trying to set lower frequencies manually with a single stick
installed then save, exit, shut down and install the second stick. Start at the
lowest available frequency, if it POSTs and runs stable then try upping it till
it fails and go back to the last frequency that worked.]]> Sat, 19 Sep 2026 01:30:06 +0000 https://forum.asrock.com/forum_posts.asp?TID=113580&PID=202035&title=x870e-taichi-lite-no-post-with-a2-b2-ram#202035 https://forum.asrock.com/forum_posts.asp?TID=113580&PID=202034&title=x870e-taichi-lite-no-post-with-a2-b2-ram#202034 Author: Assi

From https://www.techpowerup.com/review/crucial-pro-ddr5-5600-cl46-64-gb/ :
Crucial Pro DDR5 5600 64GB is organized as dual rank (harder to drive than single rank) and Micron chips (told to be less frequency stable than Hynix or Samsung).
Regarding actual chip capacities, your 128GB is dual rank too.

AMD specifications for Ryzen 9000:
https://www.amd.com/en/products/processors/desktops/ryzen/9000-series/amd-ryzen-5-9600x.html (section "connectivity")

Max Memory Speed
    2x1R    DDR5-5600
    2x2R    DDR5-5600
    4x1R    DDR5-3600
    4x2R    DDR5-3600

2x64GB brings high load on the CPU's memory controller,
so maybe DDR5-5600 or - the worst case - only DDR5-3600 may succeed.

Issues like this can't really be "fixed". A sudden, unexpected power outage can
cause firmware freezing/value corruption on any motherboard from any brand. The
"fix" is using a UPS to allow the system to properly shut down when power is cut
off unexpectedly. You can cause the same issue by turning the system off at the
PSU or wall while it's running. It's rare that it occurs but it can and does happen.

Thanks for sharing your solution. Powering off the system, disconnecting from
power then pressing and holding the power button to discharge capacitors will
fix most frozen/stuck firmware. The BIOS is not the only firmware on a modern
motherboard. If doing the above doesn't help then removing the CMOS battery
while doing the same thing will often do the trick. ]]> Fri, 18 Sep 2026 16:23:28 +0000 https://forum.asrock.com/forum_posts.asp?TID=12050&PID=202033&title=x570-gaming-phantom-4-no-ethernet-detected-win-10#202033 https://forum.asrock.com/forum_posts.asp?TID=12050&PID=202032&title=x570-gaming-phantom-4-no-ethernet-detected-win-10#202032 Author: Sixthsense

Hi Lovely people I am back again.
Guess what? I had a powercut yesterday and the ethernet port did not shown yesterday.
My wife kicked off no time about it. :-)
Now let me update you about my current status.
Bios is at ver. P4.20
I have a wifi usb dongle also plugged in.
All I did is the following:
1. Powered down the pc,
2. Switched my PSU powerwitch to 1 to 0. (This is optional you might not have it)
3. Unplug the power cable from the PSU.
4. PRESS AND HOLD the power button up to 30-40 seconds then let it go. (This will do draw the power out from the PCB)
5. Plug back your power cable to the PSU.
6. Turn on the switch to 1 if you got switch on your psu
7. Power on the pc and voilá the ethernet port shows again.
I hope this helps you guys.
It is a shame Asrock newer fixed this, or at least I do not know myself this one. If changed by now.
Kind Regards
Sixthsense
Ps. Thank you for praising my efforts on this forum.

It may be worth booting a linux distro from a flash drive and seeing if it works
under linux to rule out OS and drivers. I am afraid aside from that I am out of
ideas. I don't work at ASRock so I don't have access to a comparable system to
test with and do my own troubleshooting. ]]> Thu, 17 Sep 2026 14:42:09 +0000 https://forum.asrock.com/forum_posts.asp?TID=113583&PID=202031&title=x670e-taichi-carrara-tb-usb4-enumeration#202031 https://forum.asrock.com/forum_posts.asp?TID=113583&PID=202030&title=x670e-taichi-carrara-tb-usb4-enumeration#202030 Author: abhisheksrinivas

So dual channel is not working. That is very odd. Both channels are working
yet dual channel is not. Did you try step 3 I listed above? The only other thing
I can think of is ensuring XPM/EXPO is turned off, not "Auto", off. If that does
not work then I would recommend returning/RMAing that CPU. Given all the slots
on the motherboard work, it is highly unlikely to be the board that is the issue.
The IMC on the CPU is likely the culprit and given the cost of a CPU it's better
to be safe than sorry and just return/replace it. The RAM could have an issue
but if it is booting into the OS in single channel with both sticks installed
it seems less likely than a bad IMC. ]]> Wed, 16 Sep 2026 21:52:07 +0000 https://forum.asrock.com/forum_posts.asp?TID=113580&PID=202029&title=x870e-taichi-lite-no-post-with-a2-b2-ram#202029 https://forum.asrock.com/forum_posts.asp?TID=113580&PID=202028&title=x870e-taichi-lite-no-post-with-a2-b2-ram#202028 Author: zkost

I'm able to post as follows:

A1 - 64 GB only = true sees 64GB
A2 - 64 GB only = true sees 64GB
B1 - 64 GB only = true sees 64GB
B2 - 64 GB only = true sees 64GB

A1 + A2 - 128 GB = true sees 128GB
B1 + B2 - 128 GB = true sees 128GB

A1 + B1 - 128 GB = false no post
A2 + B2 - 128 GB = false no post (and this is the recommended one)

Weird right? ]]> Wed, 16 Sep 2026 21:25:22 +0000 https://forum.asrock.com/forum_posts.asp?TID=113580&PID=202028&title=x870e-taichi-lite-no-post-with-a2-b2-ram#202028
