Proxmox 6.3-3, CPU runs at low speed - How to Install Dell Open Manage (dell r730xd)

[dodoj]

Proxmox 6.3-3 is successfully installed at my dell r730xd server. After few difficulties, Proxmox Mail Gateway is also installed. Subscription is paid, first days in production looks good. But there is a perfomance problem. After short investigation, I detected that CPU runs at low speed.

1. cat /proc/cpuinfo | grep "MHz" shows 1200 MHz in average (varying).
2. lscpu shows that this is min speed for Intel(R) Xeon(R) CPU E5-2690 v3 @ 2.60GHz. Max goes to up-to 3500 MHz.

Windows 10 VM behave too slow, with 1.2GHz there is no power at all. I stuck here.

• As I can't reboot to come to bios, Open Manage is needed. But how to install it at Proxmox 6.3-3?
• How to increase/fix CPU speed for specific VM?

Thanks for ideas.

As I can't reboot to come to bios, Open Manage is needed. But how to install it at Proxmox 6.3-3?

Do they offer a repository for Debian Buster? Someone from the community might have more experience though as we do not have Dell hardware around here.

How to increase/fix CPU speed for specific VM?

You cannot do that specifically. As a first step, try to disable all power saving features in the BIOS. After that, you can also try to set the CPU governor . The ArchLinux wiki has a good section about it. https://wiki.archlinux.org/index.php/CPU_frequency_scaling#Scaling_governors

Thanks. I do hope that somebody in forum can help with dell Open Manage for Debian Buster.

Following ArchLinux Wiki I have issue with: root@pve:~# modprobe amd_freq_sensitivity modprobe: ERROR: could not insert 'amd_freq_sensitivity': No such device

Mod amd_freq_sensitivity however exists: root@pve:~# ls /usr/lib/modules/$(uname -r)/kernel/drivers/cpufreq/ amd_freq_sensitivity.ko p4-clockmod.ko speedstep-lib.ko

With other two, loading with modprobe was ok.
