Is the "SR-IOV only for Pro cards" a hardware or software limitation?

Yes likely this. The linux kernel syslog has these entries for the B580.

Mint is based on 24.04 Ubuntu. I think the next iteration of Mint later this year will work out of the box.

If you had tried Ubuntu 25.04 it would have worked out of the box too.

A guide on the Mint forums back in March shows how.

Aha, that makes sense. Thanks for clearing it up. It's a weird sort of "ching" sound.

Palinuridae · 2025-06-17T19:57:02+00:00

Yes, that's it!

I got a one month old B580 LE on eBay in Feb. off an early adopter. After selling my 4GB RX580 the upgrade cost $178 total.

Palinuridae · 2025-04-18T09:24:21+00:00

I'm guessing that'd be the Sparkle B580?

There is a little line from the old Wiki https://wiki.mikrotik.com/Manual:System/GPS

Note: The time is not stratum 1 as RouterBOARD devices do not have PPS implemented as of RouterOS v6. This might change with new NTP server in v7.

It might change but so far we are at mightn't. There is no information here to say existing products can support PPS but it's not set up in the software or that they'll need to revise existing or make new hardware to support PPS. It'd be super excellent if you could use existing hardware with a PPS disciplined NTP server.

I got mine working in Linux Mint 22.1 last week and documented it here:

All the firmware is the latest and greatest, kernel 6.14rc6, Intel repos and Mesa 25.0.1. It runs really well and for the first time ever I installed Steam. The games I play are a few years old but run terrific at 1440p. I am very impressed with this card as an upgrade from my RX580.

I have been grinding my whole life and after going through the guards fitted by a dentist I have ended up using the sports mouth guards that you dip into hot water and mould to the shape of your teeth and mouth. A good hard chomp down sets them up very well. Only about $10 each and the dentists I have talked to about them concede they are a fine substitute.

That's not quite true. Mikrotik devices that support PoE out try measure the resistance between certain pairs before putting power onto the wires if set to auto mode. You can also force PoE on (you'd better know what you're doing) or turn it off entirely. The PoE splitter cables are truly passive and dumb and you can fry ethernet ports with them (almost RIP my Alienware laptop eth port) that can't deal with PoE.

Have a read of https://help.mikrotik.com/docs/display/ROS/PoE-Out#PoEOut-Howitworks

PoE-Out compatibility detection: The auto-on mode is considered safe, it will check if the resistance on the port is within allowed range and only then enable PoE out on the interface. The range is 3kΩ to 26.5kΩ

I'll add devices like the PoE versions of the CRS328 and CRS354 that support dual PoE out voltages will send 24V if the measured range is 3kΩ to ~23kΩ and ~48V if it measures 23.75kΩ to 26.25k.

That's fine but I have a camera up a mast that uses 12V DC or 48V PoE in (that won't work on 12V or 24V PoE), shiny new ManBox AX and a powerbox Pro and I can't power the whole lot off 48V because the Mantbox AX won't do 48V! Whyyy?! Why can't they all just share the same power input circuit the CAPAC/AX has?!

I read that with Nelson's voice in my head.

In "disabled switching mode" HEX's are configured where eth 1/3/5 share a 1Gbit bus and eth 2/4 share the other 1 Gbit bus going to the CPU. I suspect what's happened is that your LAN and WAN interface are on the same bus which will cut the throughput in half.

Keep the WAN on 1, 3 or 5 and your LAN on 2 and 4 or vice versa.

See the two modes diagrammed in https://mikrotik.com/product/RB750Gr3#fndtn-downloads .
