Hello,
finally put my pc together on the weekend and reinstalled it from scratch. Now I see some odd behaviour with turbo clocks.
i7 7700k on Asrock Supercarrier mobo. I'm not overclocking, everything is set to stock/default/auto. I even disabled the "turbo core enhancement", lol.
In idle, all cores are at x8 multiplier, and each individual core multiplier jumps up to different intermediate speeds when something in the background needs it.
However, it never ever jumps to x45 multiplier, the highest ever was x44. Why? Cpu-z says multiplier range is 8-45.
The other thing is, when I tried to put a single thread load on the processor to see if it jumps to x45 that way: it still only went for x44, but even for a single thread load, ALL cores together jumped to x44! Shouldn't they use different individual multipliers, as in idle?
Bios settings are: multicore enhancement - disabled. turbo multiplier settings is set to Auto. when I change this to per core, I can see the board's default settings are x45@1C, x44@2C, x44@3C, x44@4C.. Speedstep, speed shift, and all C-states settings are enabled.
