HWiNFO only shows 4 cores instead of 6. I got a Ryzen 5 1600 on a MSI B350 PC Mate Mainboard. The windows task manager is showing me all 6 cores (and 12 threads).
Okey sorry, there was a little mistake in my question. So it shows me the 6 cores but it doesn't show me the temp of all 6 cores (there are only 4 vertical columns).
AMD CPUs don't support per-core temperature monitoring. They report only a single temperature for the entire CPU die.
If you see per-core temperatures in other tools, then those are just fake copies of the same value.
