By default it seems that boinc only run on the E-cores (windows 11), and the P-cores remains idle.

Is there a way to force boinc to use all cores (p-cores + e-cores togheter) without throttling? and without having to disable the E-cores on the bios?

Under Windows you could use an app called "Lasso", I think, to assign them to the P cores.  That would avoid using the Bios to disable the e-cores.

This does sound like a Windows scheduler issue.  Might try googling something like "get games to run on P-core" to see if there is a "fix".

Might try limiting Boinc to just the number of P-cores and see if that changes Window's behavior.

Good luck.

Nobody with feedback from use

Nobody with feedback from use of intel 12th and 13th generation CPU on BOINC? Uau

The last time this issue was raised the only recommendation anyone had was disable the E cores in the bios to force Boinc onto the P cores.

Might also try any of the Windows Overclocking tools to see if you can push some tasks over onto the P cores.

Seems like it is possible to assign specific applications to specific cores.  That might be a LASSO thing or something you can do in the Windows task manager.

Here is a work around to assign the task apps to p cores.

While Windows Task Manager or

While Windows Task Manager or Windows Process Explorer allow you easily to set CPU affinity for a running task, that assignment is not inherited by the next instance of the task.  That makes this method useless for Einstein purposes, where you generally want the new copy of task launched on starting each WU to be affected.

That exact thing is a specialty of Process Lasso.  While you are at it, in addition to setting CPU affinity, you can also alter some priorities from their defaults.

I am wondering just how

I am wondering just how flexible lowering your power limit might be. I am assuming this is via bios settings. I am ignoring the ability to set the number of boinc tasks arbitrarily low.

With Ryzen CPU's it appears you can lower the power limit to an arbitrarily low number (like 35 watts).

Can you do the same on Amd Epyc CPU's Or Threadrippers?

What about Intel cpus?

Arm CPUs?

Ryzens have a ECO mode

Ryzens have a ECO mode available which drops their wattage down to 65W.

Some Epycs have a range of TDP in the specs. Spec might say TDP 170-240W and can be set in the UEFI TDP and PPT settings.

Some Epycs are just locked to one spec like 240W.

Keith, Tom and George have

Keith, Tom and George have you guys read this article on NVMe M.2 drive cooling? And do you use one on your own pc's?

No I don't use anything special for my M.2 drives.  For the motherboards that include a stock M.2 heatsink, I just use what's provided.

For the Epyc motherboards that don't have anything to offer for M.2 heat sink cooling, I just use them naked on the board.

But I have good case airflow in all my hosts and never have any issues with M.2 cooling or throttling.

All my M.2 temps are in the mid 30's or low 40's at most.
