Question Does Hyperthreading lower the CPU frequency ?

[Larzeax]

Hey there,
I recently set up a Minecraft Server on a Debian based system with an i3 3220, but the CPU frequency shown is just round about 1600 MHz. The i3 hasn't any boost clocks. Just the standard 3.2 MHz. I did look up the CPU frequency with the following command:

watch -n.1 "grep \"^[c]pu MHz\" /proc/cpuinfo"

Could this be caused by Hyperthreading or did I just use the wrong command?

Hyperthreading wouldn't cause cpu to lower base speeds unless it's thermal throttling.

Check live speeds + temp with Coretemp.

Check live speeds + temp with Coretemp.

I did, but the CPU is at only 30 °C and the clock stays at 1600 ± 100 MHz

Somehow the cpu is locked to that speed and is unusual. Hyperthreading wouldn't cause that, turn it off and see.

Try reset bios, could be a setting there forcing an underclock.

Windows power plan for processor state hasn't been altered yeah?

BIOS Reset didn’t work. I don‘t run Windows, so Windows PP can‘t be the problem.
I thought maybe the PSU is the problem, because it’s a Dell 170 Watt with only 20 pins for the Mainboard.
