Moin experts,

the following phenomenon with an old Ryzen 1700 on an Asrock board Taichi X-370:

When the project DENIS is running, the computer clocks approx. with half CPU frequency!

The display (Conky) under Linux-Cinnamon 20.4 goes to 100%, but clocks only with about 1650 Mhz.

Also if other projects are used, this occurs.

Only when all DENIS are done, the computer clocks again to its nominal 3200 Mhz.

First I searched in the BIOS, which does its job unchanged for years.
Even with the stock BIOS or even the settings of JZ, but that was not it: It is only because of DENIS!

Consequently, the computer now no longer calculates DENIS, but serves other objects.
I wanted to describe it here only so that the inclined user does not search.

All other boxes run with DENIS without problems, only the Ryzen 1700 does not.
It's probably programmed in Commodore Basic V2.

Greetings, Rainer

Make sure the machine is not thermal throttling ie clocking itself down due to the CPU getting too hot.
Distributed computing work stresses the CPU cooling greatly, so make sure you have sufficient airflow through the machine, that the coolers are not clogged with dust, and that all the fans are clean and functioning properly. If you do not have temperature monitoring software installed now is a good time to do so and keep an eye on it.

Thanks for the contribution, but it does nothing.

I am already 2-3 days with Boinc and know my way around.

In my post was also mentioned Conky, which allows a display tool for any hardware information under Linux....

The temperatures are at nominal clock at about 54° under full load.

So that can't be the problem.

Greetings Rainer

I think all is running as it should. My Ryzen 3200 behaves the same way but I see it as DENIS work only needs half the cycles so Ryzen throttles back while other projects require full CPU speed.
When I exit BOINC and stop all calculations the CPU speed drops to only a few hundred MHz.
