my i7 6700 reaches 3,7ghz when running cinebench r15, which is corrrect. However, in single core cinebench r15 test , it reaches at max 3.9ghz. Is it cpu's error? It should be at 4ghz
I use cpu-z to monitor the clock speed.
The processor base clock should be 3.4Ghz, if all cores are enabled and turbo boost the speed will go up to 4Ghz.
Try disabling Enhanced Intel® SpeedStep® Technology (EIST) through BIOS and run the monitoring software again.
