If Intel Speed Shift is turned on then is CPU clocking still on the highest frequencies (despite on constant minimum ussage of CPU!). CPU heats like fool.
If i turn down this technology in Bios then is CPU power controlled by Windows itself (By Intel SpeedStep technology). In this case is clocking very reasonable! See attached picture.
Attached picture measured aproximately 2 minutes without load CPU (without any ussage). Power profile setting Minimum CPU = 0%, Maximum CPU = 100%
Whats wrong with it? Unique CPU bug, system CPU bug?
Thank you for reply. I get it. Also I tested the CPU by intel processor diag tool. It seems to be ok, in all case of test was gap around 20°C. I have one more question. I read it exist some Energy-Performance Preference. It does somehow relate with Speed shift technology?
Im able to enable or disable this technology in Bios, but this parameter is not present to set. I read in internet forums, it somehow set an "agresivity of reaction on load of MCU" of the technology. I believe Intel Speed Shift is valuable. But in my case CPU is still on highest power despite CPU usage is somewhere around 0-3%, consumed by minor background processess.. From my point of view Intel Speed shift should recognize this minor background traffic and should set much lower power... Actually Im aware on background is running really lot of very short transients (mentioned 0-3%) which rise maximal power almost all the time. I believe some other parameter is hidden for me. Does exist some way, how to set this EPP parameter?
Thank you Alberto,
wish you nice day.
