Review: A piece of Junk or it is not compatible with my Asus X670E-E Motherboard supposed to work with it - Works great if you hook it up correctly! Using an ZikeDrive Model Z666 USB4 M.2 Nmve case (they claim the fastest M.2 Drive Case): and an Fanxiang S880 4TB M.2 Nmve I get the fastest speeds of 3050.32 MB/s read, 2689.04 using Crystal Disk Mark 8 speed test. Running the Orico TCM-U4 Thunderbolt4 USB4 case with an Fanxiang S880 4TB M.2 I get the speeds: 3049.98 MB/s read, 2689.04 MB/s write. The Orico TCM-U4 is cheaper, but has a cooling problem with its top installed - but works great with thermal strip and copper heat sink and no top installed - it is reliable. But the ZikeDrive Model Z666 USB4 M.2 is slightly faster, has excellent cooling so far - better heat sink metal case with plastic over it - but the ZikeDrive is not as reliable when running thru my Plugable TB4 USB4 Hub (cant boot computer with it hooked in w/o error - sometimes errors if it is plugged in after computer booted? Seems to be working ok now.) The above ZikeDrive Model Z66 with Fanxian S880 4TB when plugged into Plugable TB4 USB4 Hub to Asus ThunderboltEx4 will get 2977.65 MB/s read, 1893.94 MB/s write for anyone who is interested. This same Fanxian S880 4TB when plugged into my Asus Hyper M.2 X16 Gen 4 Card or my Asus X670E-E motherboard M.2 PCIe 5.0 slot runs at 7271.24 MB/s read, 6187.19 MB/s write. So you can see the bottle neck is not in the M.2 I am using. It is cable of this speed, but Thunderbol 3 or 4 or USB4 is not cable of that speed. (I can't wait for Thunderbolt 5! I hope it works with my motherboard!) I am running Windows 10 & Windows 11 dual boot. Tests were done in Windows 10 on a Asus X670E-E Motherboard with AMD Ryzen 7950X3D CPU and using the GPU: MSI Gaming GeForce RTX 3060 Ti 8GB OC Edition "BGB GDDRR6X". And 96 GB DDR5 RAM (GSkill) 5400Mhz. So this is a top notch AMD computer build and is quite fast. I boot from an XPG 4TB GAMMIX S70 Blade PCIe Gen4 M.2 2280 Internal Gaming SSD Up to 7,400 MB/s in the PCIe 4.0 internal M.2 slot on the Asus Motherboard. (It has 3 PCIe 5.0 M.2 slots too reserved for future Raid-0 for video recording/editing and audio, etc.) To get this to work properly you MUST plug it into the proper PCIe X4 slot, plug the included cable from the USB 2.0 port on it into the USB 2.0 header on your motherboard, and plug the included cable from Thunderbolt Header on it into the Thunderbolt Header on your motherboard. If you don't hook it up to the USB 2.0, USB Devices can work on it, but no Thunderbolt. I have an Orico TCM-U4 Thunderbolt4 USB4 case with an Fanxiang S880 4TB M.2 in it, it was running at 1063.91 MB/s read, 1057 MB/s write, when the ThunderboltEx4 was not hooked up from its USB 2.0 to the USB 2.0 header on the motherboard. But when the ThunboltEx4 was hooked up correctly (USB 2.0 on it to USB 2.0 header on motherboard) then it was running at 3049.98 MB/s read, 2689.04 MB/s write, using the Fanxiang S880 4TB M.2. Review: Works great on z790-E - Works great with z790-E mobos, and installation is easy and smooth. Remember to check compatibility before ordering. ## Features - 1.

BTW, the only Intel processors with native PCIe 4.0 support are generation 11 and up. **Q: How many pcie lanes does this require?** A: It use PCI-E 3.0 4 Lane. Mainboard must support Thunderbolt header. I think Z590 chipset mainboard need Thunderboltex4 card. **Q: will this work on my "z370 gaming pro carbon (ms-7b45)"? i already ordered but im making sure** A: Yes. Just make sure to download and update all your drivers **Q: Is this card compatible with alienware aurora r11 dell computer?** A: It will pobably have limited functionality if your mother board like mine does not have a an asus proprietary tb4 header, I’ve only used my tb4 the two type c for video output to my g9 ## Customer Reviews ### ⭐⭐⭐⭐⭐ A piece of Junk or it is not compatible with my Asus X670E-E Motherboard supposed to work with it *by J***N on November 5, 2023* Works great if you hook it up correctly!

Remember to check compatibility before ordering. ### ⭐⭐⭐⭐⭐ Works as expected with Windows 10 and OWC TB Pro Dock *by J***N on July 26, 2023* After installing the card, connecting the TB/USB headers (opted to skip the PCIe as I don't need the PD functionality), and enabling TB4/USB4 (under AMD BPS for X670E BIOS), and downloading the TB manager from Asus' site it works exactly as expected. I can now swap my mouse/keyboard, 10Gig ethernet, and monitor (3440x1440p 175hz HDR) between my windows and macs with a single cable. The fit on the thunderbolt ports seems to be very loose, bumping the cable at all seems to result in a disconnect. There are also some quirks with Windows, sometimes it won't display HDR at 175hz at my native res (it will always do so if I drop to 144hz), and it doesn't seem to want to reconnect to the OWC Thunderbolt Pro Dock if I unplug and reseat the cable without powering the Windows machine off. (This may have been a Windows 10 issue, it now lets me disconnect/reconnect without power cycling just fine on Windows 11) At the end of the day, this has greatly simplified my current desk setup and I'll definitely be buying a motherboard with included Thunderbolt next time I'm in the market for an upgrade. ## Frequently Bought Together - ASUS ThunderboltEX 4 with Intel® Thunderbolt™ 4 JHL 8540 Controller, 2 USB Type-C Ports, up to 40Gb/s bi-Directional Bandwidth, DisplayPort 1.4 Support, up to 100W Quick Charge, Black - Cable Matters [Intel Certified] 40Gbps Thunderbolt 4 Cable 3.3ft with 8K Video and 240W Charging - 1m, Compatible with USB4, Thunderbolt 3 Cable and USB-C --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/311275102-asus-thunderboltex-4-with-intel-thunderbolt-4-jhl-8540-controller](https://www.desertcart.co.th/products/311275102-asus-thunderboltex-4-with-intel-thunderbolt-4-jhl-8540-controller) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-05-16*
