If its this one, i think the AMD rep only mentions hwinfo with dont have multiple monitoring apps open that might contend.

There is a further response from Martin hwinfo in that thread .
Not trying to be contrary, I dont have Ryzen 3000 so cant try it myself ( currently 2700x ) but am considering it , couldn't live without Hwinfo, see interested to see where this goes ..
I still don't have any confirmation that HWiNFO would be affected by this phenomenon. It is not polling the CPU as aggressively as described, so I don't expect a big issue here.
Honestly speaking, this time AMD has failed big in supporting 3rd party tools. We are still missing several information and advanced support. Some quirks (like detection of sleeping cores) is AMD keeping for themselves, which is a shame. I'm ready to investigate this issue in more detail and take actions if needed. But this requires support from the other side too.
Today I'm planning to release a new Beta build of HWiNFO (v6.09-3855), which should reduce the CPU polling a bit more.

Might be worth trying the beta if you've Ryzen 3000
