You can grab the new smu ucode here:
It will be upstreamed to linux-firmware once it's completed our internal QA cycle. You can run the 19.50 packages or upstream code on the RX 5600 boards. If they have the old vbios, they will work fine. If they have the new vbios you can still use them with the old smc ucode, you'll just get slower performance.

Hello
Thanks for the new firmware its finally allowed me to flash my PowerColor Red Devil RX5600 XT.
The clocks went from a boost clock of 1650Mhz to 1780Mhz, and memory clock of 1500Mhz to 1750Mhz.
However when its running the desktop its running at 800Mhz (according to radeontop) it never throttles in games (Witcher 3/Wine) its constantly at its boost clock and after about 10 mins and temps are in the high 80s and it green screens. Shouldn't it reach a temperature and throttle back to standard clocks at some point?

The latest driver pack released by AMD is version 19.50 which adds support for RX 5500. The kernel would also require some modifications.
At moment, running more than a basic console on this card should be simply impossible.
How can you not only run X but even test games..???
Infos on how to make those games run on Linux would also be appreciated...
Thanks for your answer!

In the meantime, as long as your board does not have the updated VBIOS (which is likely but not definite) then any distro with good Navi10 support should work IIRC.
Which distro/version are you running ?

I don't know why Michael had all those performance issues, I had no performance issues at all, just a couple weird rendering issues with certain games but that's a mesa or dxvk issue not a firmware one.

I thought the memory clock dropped even lower with a flashed Pulse and previous firmware; have you picked up the new firmware yet ? If not it would be worth giving it a try.
