i have some systems running xmrig under linux. 2 of them are Ryzen 9 5950X with a big CPU water cooling. In xmrig Benchmark i saw, that it can hash up to 25kHs - i get at most ~15kHs. I have play around with Kernel params, bios Settings, over- and undervoltage and a lot of other Options. My stable System has not more the 15kHs produced. Mainboards are new, all updates are done.
Also i see, that it does not a big dfference, if i use 26 of 32 CPU’s or all of them. The result is likely the same.
What is the trick?
