Zen3 (Ryzen 5000) support

[hattedsquirrel]

After patching zenpower as described in ocerman/zenpower#39 I got zenmonitor working on a Ryzen 5000 series processor as well. Zen3 is familiy 19h. Everything else seems to be similar to the previous versions.

Can confirm that this patch works on my 5800X as well.

Great work, thank you!

(You should totally make a pull request out of this.)

Works with the 5900X too

Thank you very much.

[worzel910]

Works fine here too! 5950x

Much appreciated.

I also followed the patch as in ocerman/zenpower#39. My CPU is 5950x and I do not overclock my CPU. As in the attached photo, one of the core reached 11GHz! is this a bug?

zenpower3 and zenmonitor3 are actively maintained forks of this project that have Zen 3 support.

@Ta180m zenpower/zenmonitor already works with the patches mentioned in the comments above.
Could you explain what else was changed/improved besides that in your fork? Thanks

I can merge new pull requests, unlike this project which is inactive. For example, I merged the four pending PRs for zenmonitor to my fork.

Change define #ZEN3_FAMILY 0x19 to
#define ZEN3_FAMILY 0x1A to get ZEN 5 detected
