May 24, 20215 yr Small issue (?) with CPU scaling in HP z820 with 2 x Xeon E5-2695 v2, baseclock is 2.4GHz, turbo up to 3.2Ghz, system is using Intel CPU Freq driver bu default, same behavior is with intep_pstate if activated - Using "ondemand" or "conservative" and turbo activated frequency is between 1.2 - 2.4Ghz, does not turbo at any point, changing turbo on/off does not change behavior - Using "performance" frequency is between 2.4 - 3.2Ghz, does not "idle" under baseclock meaning unnecessary heat and power consumption Ideally we would get "ondemand" with turbo? Any ideas? I know a CPU does not turbo with all cores, turbo works since I can clearly see it loading one core, grepping /proc/cpuinfo and using performance governor.
