This only happens with 'Threading Tech' applied ...

Opteron (as with any CPU that uses HyperThreading Type of technology) is classically using only the cores allotted, but with HyperThreading Tech enables, it uses the SAME cores but different time slices. Which means you have 64 Physical Cores and another 64 'SoftWare' Cores - making 128 Cores in total. That is IF this is happening here with this machine.

So even though it is showing only 50% usage of all 'SoftWare' Cores, the physical cores are actually being used to close to full capacity. You may get some increase in hashing, but I would assume very little if you set your miner thread count at 128.

You can test it and see, it can't really hurt the Physical CPU's themselves, but the whole OS may slow down considerably so be prepared to wait for things to happen when you click

These Opteron CPU's were incredible in their day. Now the Epyc CPU's show what REAL CPU Power is all about!
