Patiently waiting for this to show up as well. Would love to test one.
Realtek 10 GbE USB Adapters might be on the way?

Another brand RTL8127 has turned up on alibaba + aliexpress looks to be made by IOCREST
It looks identical to my RTL8125B 2.5 Gbps IOCREST nics
Worked out £27.61 inc 20% TAX Delivered with a discount code
I picked one up will run it in a 3.0 x1 port for what? 8 Gbps with jumbo frames maybe

Thanks to this article I found this PCI-e version from Alibaba while looking actually for a M.2 version (the Auvidea M20E is one but pricey at ~EUR100 and 5 weeks lead time) .
Realtek RTL8127 10GbE PCIe cards and M.2 modules are starting to show up for $35 and up - CNX Software

Waiting for IOCrest to release their m.2 variant as that'll be the really interesting one for me (in addition to pcie4x1 sfp.)
Can't wait for someone to get the SFP ones in stock
Also any word on pci 3.0 2x or 4x versions ?

The 4x SFP+ variant (which I bought from spreenow/taobao) seems to be available on aliexpress now: https://de.aliexpress.com/item/1005010287958266.html
the price might seem a lot but is basically the same as what I paid on spreenow after their paypal fee, the double-shipping, their 10% order fee and taxes.

I think there were already posted in previous posts on this thread if you want to skim through. I was checking earlier today for the M.2 versions so I checked.
The card in the photos is identical to the card @Shonk pointed us at earlier, which was $10 cheaper for NZ delivery from alibaba.

My spreenow/taobao order just arrived:
I didn't do much testing yet, but:
- I'm super relieved that the SFP card comes with a low profile bracket, since that isn't mentioned anywhere and I was already thinking about how to make my own.
- I think the Hellotek module needs around 2W, but I don't have clear numbers on that since I'm measuring my whole rack.
- While the Hellotek just says HTK-FR812 like in the Computex images, The packaging says HTK-812B, which does exist on the companies website. I may order the HTK813L as well to see if it actually has even lower power consumption.
EDIT: while the card is physically 4x wide, only 2x lanes are connected, meaning with Gen3, the max theoretical throughput is 15.752 GBit/s,meaning you can't do full duplex 10G unless you use it with a single Gen4 lane. It's 15.752 GBit/s, PER DIRECTION, so no issues here.

In Linux, the SFP+ card doesn't work with the mainline driver. It is detected but never gets a link. I've reported that already: RTL8127AF doesn't get a link over SFP+ DAC
The proprietary driver does work, but I haven't speed-tested it yet or anything like that: Realtek

My RTL8127AT turned up today it didnt come in a retail box like the RTL8127 did
when i installed the drivers it was showing as no link
disable and re enable the nic caused a code 10 and the card was gone
checking the event log showed
I can either disable PCH ASPM in the bios or use the Realtek Drivers with ASPM disabled at the driver level
I opted to use the drivers with ASPM disabled but tested both methods
Seems fine then

By the looks of it they havnt got aspm stable in the drivers yet and forgot to disable ASPM in the drivers for the RTL8127AT it's disabled on the RTL8127 card with the current drivers so didnt encounter any issues

Hello there, first post here.
I got 2 USB 3.2 x2 to 10Gbps that should arrive for Monday or such. I want to check the speed at either Gen 3.2 and Gen 3.2x2.
Got these ones https://es.aliexpress.com/item/1005...st_main.4.d3611802e2wDnn&gatewayAdapt=glo2esp
Seems here it is more discounted (I bought it before 11/11) here.

Which kernel are you running the prop driver on? I upgraded a proxmox box to 6.17 to run one of these & I'd rather not downgrade.
My Other brand RTL8127 Came just now
It comes with a newer UEFI Option Rom than the DIEWU cards come with
also the hardware revision is the newer 07 (same as my DIEWU RTL8127AT my DIEWU RTL8127 is Rev 05)
ASPM had the same problem on MY Z390 Aorus Master F13 bios and the DIEWU RTL8127AT you have to run either ASPM disabled drivers
or disable PCH ASPM in the UEFI

In Linux with the proprietary driver I also have lower performance unless I disable ASPM in the driver itself(not globally). Using the Gen3x2 SFP+ card.
