HWMonitor has my 4900hs trying to upgrade itself.

It's usually 439xMHz max, occasionally a core is 443x-445x max.

...but two cores hit 4561MHz?

[Edit: I'm thinking it may be legit due to the Mins being 87MHz, also a low I've never seen.]

I forgot I had a window open @ 33f, so it was a bit colder than normal and am on a decent cooler.

Are Ryzen CPUs designed to clock past the stated max like the nvidia GPU if temps allow?

I was downloading the new Outriders demo from Steam and saw I was getting 3/4ths of the cores just shy of 4.5ghz on a CPU that supposed to top out at 4.3. ...so another pic.
