jhrfc Posted January 16, 2018 Share Posted January 16, 2018 on 10.13.2 anybody else noticed their system doesn't seem to speed step down much at all any more? on idle my cores would drop down below 2ghz, but now seem more or less permanently up at the max of 3.36ghz. although occasionally one core does drop down to 3.2 ghz the default speed. but they never drop down below the 3.2ghz. Hopefully not a side effect of the meltdown prevention changes in 10.13.2! I upgraded direct form 10.11, where i have had a stable setup for several years including the speedstep.

jhrfc Posted January 17, 2018 Author Share Posted January 17, 2018 i7-920? Make sure you generate C States + P States. Thanks! actually, mine is now idling properly, i think it may have been spotlight indexing or something, happening after my upgrade. (using the DSDT i have for years with c and p states unchanged) Link to comment Share on other sites More sharing options...
