    The system gives only the base frequency

      I don't see this as an XCP-NG issue. A hardware forum where someone can help with overclocking would be a better place to post.

        @NikFer This is very likely a BIOS setting. My experience has been with Dell hardware, so I cannot speak specifically to SuperMicro configurations, but see if this might help or check one of the SuperMicro forums: https://www.supermicro.com/support/faqs/faq.cfm?faq=21555

          Are you talking about "base clock" vs "turbo clock"?

          If yes, you can try:

          xenpm get-cpufreq-para | fgrep turbo

          --> To see, if turbo is possible

          xenpm start 1|grep "Avg freq"

          --> To see the average frequency

          xenpm set-scaling-governor performance

          --> To force Turbo-Mode

          Stress the CPU and check, if the clock is above "base clock"...

              @KPS seems to show that you can make a turbo! But for some reason, in guest operating systems everything is 2.2 GHz

                      This is common for all virtualization products, I have ever been using.

                      But: Do you think, the community will get motivated by finding your "I will just post lots of screenshots and uncommented output and you are free to find out, what I want"?

                        @KPS Good day. I'll try to explain in more detail. For the above processors, I set turbo mode in the BIOS and want to get turbo frequency in guest virtual machines. but if I use command xenpm, I can see that there is a turbo frequency. But the hymervisor itself in the xen center does not show the turbo frequency. And the same in guest VMs.

                            @KPS And I’m also trying to install the oops utility cpupowerutils, but nothing works - Epel release is not installed. Is it worth installing? Will it help me?
