The system gives only the base frequency

Re: xcp-ng CPU low performance issue

Hi all! There are 2*xeon 8360y on Supermicro 12dai-n6.!
The system gives only the base frequency in both the BIOS and the hypervisor. Tell me how to overclock?

@NikFer
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

@NikFer

@KPS In guest VM with CentOS7:
lscpu | grep "MHz"
CPU MHz: 2200.217

[NikFer]

@KPS
[14:21 xcp-ng ~]# lscpu | grep "MHz"
CPU MHz: 2200.096
[14:21 xcp-ng ~]#

@NikFer
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.

@lawrencesystems Hello! This question is directly related to the hypervisor.

[NikFer]

@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?
