blackmanga Posted March 26, 2019 Share #1 Posted March 26, 2019 Hi, I have read through most of the threads on CPU power throttling and am still not sure I have a proper solution to reduce CPU dynamic scaling. I can only use the following governors (powersave/performance) - which as someone pointed out, are the only ones available with intel_pstates. However, when I choose either of them, my CPU is stuck at 3.4Ghz (performance) or 800Mhz (powersave) without any dynamic scaling or boost. Specs HW: CPU: Xeon E3 1245 v3, MB: Gigabyte H97N WiFi, RAM: 16GB - 2x8GB 1600Mhz I am using 1.04b bootloader and running DSM 6.2.1 - 23824 update 6 on DS918+ Xpenology. @Olegin I believe you have the same motherboard. Is there anything specific that I need to do in the bios to enable the dynamic scaling ? Really appreciate any assistance in advance.

Olegin Posted March 26, 2019 Share #3 Posted March 26, 2019 @blackmanga There are no ondemand and conservative governors in 918 DSM version, but they are present in 3615/3617. Quote Link to comment Share on other sites More sharing options...
blackmanga Posted March 26, 2019 Author Share #4 Posted March 26, 2019 Hi Olegin, thank you for your reply. So dynamic scaling doesn't exist for powersave/performance governos. i.e. the CPU will always run at the fixed frequency when its in those modes. Is my understanding correct ? I am not too fussed about HW transcoding at the moment, so I will revert to 3617xs and DSM 6.2 if that is the case. Quote Link to comment Share on other sites More sharing options...

mervincm Posted April 5, 2019 Share #7 Posted April 5, 2019 What about Turbo? that CPU should scale up to 3.8 with Turbo. Is that supported under the 3615x/17x ? Quote Link to comment Share on other sites More sharing options...
Trauma Posted August 16, 2019 Share #8 Posted August 16, 2019 I guess some off you could be intersted in this : Quote Link to comment Share on other sites More sharing options...
gatsu_1981 Posted January 31, 2020 Share #9 Posted January 31, 2020 Hello, does it use turbo frequency? I see my i5-4460T limited from 800 to 1900mhz, never going up to 2.7ghz. Quote Link to comment Share on other sites More sharing options...
