Point of clarification since it isn’t clear from the title. This isn’t a Framework product, but a product by Wisdpi designed for the Framework Expansion Card form factor.

Very cool to see an ecosystem developing around that form factor. Like the old PCMCIA, except not awful.

I do wish there were something like Oculink, but with power available over the connector. USB-C does almost everything, but it seems the chips to break out PCIe lanes for USB4/Thunderbolt for higher speed devices are still a significant cost for accessories.

I have a 10GbE network in my house and a Framework 13 AMD laptop (7840U variant), I found that most of the available 10GbE adapters on the market get too hot, and after trying a few I settled on the UniFi USB4 10GbE adapter as it has enough thermal dissipation to be able to sustain full performance over an extended period of time. I don't see how you can dissipate enough heat in the Framework insert shells.

I'm not sure why you want to either really. I can't see many scenarios where the absolute portability of having a 10GBE adapter in the laptop is really necessary. I suspect the general use of these kind of things is for people docked at a desk, at which point its best served by a well cooled dongle or a chunky dock like a TS5

> The Pi 4 / 5 will run OKish without a heatsink at idle wattages, but thermal throttle quickly if you attempt to do something intensive. Even with a heatsink and fan, I had to upgrade to a higher quality set to keep Jellyfin from thermal throttling a Pi5 while transcoding 4K video.

4k video transcoding is anything but an idle load.

Especially on the Pi 5, which has no hardware encoder to save on power consumption for that task. It's entirely in the CPU.

(Technically the Pi 4's hw encoder doesn't go up to 4K either, though, so I guess moot point).

Every PCIe 10G ethernet card I've seen has a heatsink on it, sometimes covering the entire card or even have little fans on the heatsink. Expecting it to work full time in a laptop is a bit of a stretch of the heat dissipation budget. Also, the laptop he is working has the AMD FP8 chipset - depending on how the ports are setup, he might only get 10G USB, if the ports are allocated to video instead.

So the entire Framework card's casing should have been copper?

If the whole thing were metal, the outer casing would transfer heat to skin too quickly, probably, for safety.

In a way, I kinda don't get the idea of an expansion card for ethernet, rather than just a dongle. Specifically, as in this case, where it sticks out from the side of the chassis. If I'm on the go, I'll have to take it out of the chassis while it's in my bag so I don't damage it. In that case, it's easier to have a regular USB-C card in that port, and toss a dongle in my bag instead of the expansion card. If I'm not…

A lot of people use their laptop as a desktop replacement and kinda leave it in one spot or only move it between two spots (home desk/office desk) rather than as an actually portable take anywhere use anywhere situation

Then dock it - these things have USB4 / TB, may as well get a TS5 and cover all your bases in one wire.

If you have a fixed computer or NAS, stop making excuses and install a 10G fiber card in it. If you have a laptop or TV it probably doesn't need 10G.

Fibre requires conduit with specific radius bends, making it difficult to route through a house.

You'd be amazed what exists on the market these days. For example, the pre-terminated InvisiLight fiber cabling is 0.6mm in diameter and has a 2.5mm bend radius. I've personally installed this cabling while making many 90 degree (and sharper in some cases) bends without any issues. That makes it easy to hide and trivial to fit right through doorways and other tight spaces too.

hey Nirav, dumb question: would it be possible to have usb-c ethernet adapters using intel chips in order to have vPro features on framework laptops (along with vpro-enabled intel chips) ? That's probably the missing cherry on top, as having vpro once the framework motherboard gets reused as a home server it gives some manageability features.

vPro requires the NIC to be connected directly to the PCH (over PCIe/CNV). This is going over USB, which won't cut it.

An Intel WLAN card in an M.2 slot on the mainboard might work (given your givens; a vPro enabled chipset).

There’s nothing to “get”. The circuit doesn’t fit inside the slot for expansion cards. You could plug in a dongle instead, but then you’d have a big hole in your laptop with a cable sticking out. Or you could just get a wider laptop bag. They make them in multiple sizes, you know.

Er, no, then you'd use the regular USB-C expansion card and plug the dongle into that, and then the port becomes generally useful. A wider bag doesn't solve it. The part that sticks out could still easily snag on something. I wouldn't want to take that risk, and I doubt many people would. I feel like you're arguing just to argue...

Not arguing, just saying that sometimes things come with compromises. It shouldn’t be surprising to anyone that some expansion cards don't fit in the expansion slot. There’s always going to be _something_ that needs a bit more space.

I was doing a comparison of 10G ethernet NICs just yesterday and ChatGPT was insistent that they are scorching regardless of actual throughput. Unless you manually downshift and upshift the communication rate.

I'm having second thoughts about having one of those dongles on my desk all day for the same reason wireless charging seems wasteful.
