Crosshair VIII Extreme Thunderbolt firmware update

[boorya]

External USB4 drive won't work in 40GBps/PCI-E mode when connected TB4 ports on motherboard and falls back to 10GBps/UASP.
Intel JHL8540 on my motherboard has NVM version 28 (that's very old), and there is at least NVM version 36 for this controller.
I believe that is the reason of failure.
The drive works with 40GBps speed on other devces, like Macbook Air (2022) and Dell XPS 15 (2021).
Is there a way to update this firmware? I know that ASUS does provide updates for thunderbolt firmware on other motherboards.

I tried to contact support, they were of no help. case E23120048640-0001

ROG CROSSHAIR VIII EXTREME BIOS 1402

Thunderbolt drivers 1.41.1379.0
JEYI TB2464 ASM2464PD firmware 231204850000

Hello, @boorya 

May I ask if the situation you described happened after any changes were made? For example, updating the BIOS or connecting an external device
The current Intel Thunderbolt driver provided on the ROG CROSSHAIR VIII EXTREME official website is version 1.41.1193.0.
Could you kindly install this driver version before reconfirm the transfer speed?

If the issue of the external hard drive slowdown cannot be resolved, could you please provide the following information to help us further investigate?
- the images of the setting in BIOS, or whether it is the default
- the brand and model name of the CPU, GPU, RAM (part number as well), SSD/HDD, and PSU currently installed
- details on which slots on the motherboard you have tested
- screenshots of the Thunderbolt 4 firmware version and the read/write speeds when using the Thunderbolt 4 port and USB 3.2 port on the motherboard

Thank you.

It does not work either with driver from asus website =(
It's not a hard drive, it's NVMe SSD inside of ASM2464PD-based case, see
https://www.asmedia.com.tw/product/802zX91Yw3tsFgm4/C64ZX59yu4sY1GW5
https://www.jeyi.com/products/jeyi-40gbps-usb-4-0-m-2-nvme-ssd-enclosure-m2-to-type-c-4-0-solid-stat...
Only two TB4 ports on this motherboard, neither work in 40GBps/PCIe tunneling mode

Benchmarks when connected to different ports on my PC:

I didn't buy this device until i was already on current version of BIOS - 1402, so I haven't tested it on previous BIOS versions.
No BIOS update actually changes thunderbolt firmware, however i can try flashing back.

PC configuration:
AMD Ryzen 9 5900X CPU
Gigabyte GV-R69XTAORUSX WB-16GD GPU
G Skill Trident Z Royal F4-4000C14-16GTRS RAM
Kingston SFYRD2000G SSD

I need to actually disassemble PC to lookup RAM part number, will post shortly.

Hello, @boorya 

Thank you for providing the relevant specifications and information.
According to the description in the link you provided, "The JEYI ASM2464 NVMe Enclosure 40G transforms your M.2 NVMe SSD into a compact and portable mobile hard drive enclosure." and the current hard drive installed on the board's M.2 slot is the Kingston SFYRD2000G SSD.
Could you please provide the brand and model of the M.2 SSD installed in the JEYI TB2464?
If connected directly to the motherboard without using the SSD case, has there been any improvement in the transfer speed issue?
Additionally, regarding the transfer speed screenshots you provided, could you please label the results for each port to indicate where they are connected?

Thank you.

[boorya]

SSD inside the case is WD SN850 1Tb, this is the speed when connected to M.2_1 slot (PCI-E 4.0 x4, directly from CPU, not through chipset):

 U32G2X2_E1 (USB 3.2 Gen2x2 Type-C @ Front Panel connector), from onboard ASM3241 chip:

- the case is recognised as UASP device at 3.2 gen2x2 20GBps transfer speed, that is correct and expected

USB 3.2 Gen 2 Type-A port 1 @ Rear I/O connection, directly from CPU USB controller:

  - the case is recognised as UASP device at 3.2 gen2 10GBps transfer speed, that is correct and expected

USB 3.2 Gen 2 Type-A port 8 @ Rear I/O connection, through x570 chipset USB controller:

  - the case is recognised as UASP device at 3.2 gen2 10GBps transfer speed, that is correct and expected

Thunderbolt 4 USB Type-C ports E1/E2 @ Rear I/O connection, onboard Intel JHL8540 (Maple Ridge 4C 2020) Thunderbolt 4 controller:

- the case is recognised as UASP device at 3.2 gen2 10GBps transfer speed, that is not correct,
expected link speed would be 40GBps, and expected device type would be NVMe PCI-E controller, not UASP device.

Here is a screenshot of hwinfo bus tree, when device is connected to one of Thunderbolt 4 ports: 

I also tried using different USB-C cables, no difference.

There is USB diagnostics utility from Windows SDK, usbview.exe,
here is the output about this device when connected to one of thunderbolt ports:

Hello, @boorya 

Thank you for providing comprehensive information.
I have now consolidated the details and sought further consultation from the relevant teams.
Could you alsp confirm if the Kingston SFYRD2000G SSD is currently installed inside the JEYI TB2464 ASM2464PD?
If you cross-test by directly installing it on the motherboard, bypassing the JEYI TB2464 connection, do you still experience abnormal transmission speeds?

Thank you.

As i wrote earlier, SSD inside the enclosure is WD SN850 1Tb (shows as WDS100T1X0E-00AFY0) and it shows this level of perfomance when installed directly to one of DIMM.2 slots:
