Should i leave Global C-States Disabled by default?

[MatrixQW]

I am replying to you from my old pc with b365 motherboard and i9400f cpu with c states disabled and turboboost working just fine like i said before

I know this is how Intel Turbo Boost works, it's by design, so no idea how you have it working since your cpu isn't even unlocked.

So guys i did not get anything,so i have i5 6600 in the intel site it says "Intel® Core™ i5-6600 Processor 6M Cache, up to 3.90 GHz" i have it for 2 years i have never seen go above 3.3GHz,so guys how can i test and see if i must disable all c-state like show on the picture,and then just enable "Intel Speed Step Technology".Because right now all the c-states are off and "Intel Speed Step Technology" is off.And it task manager says 3.31ghz.

Select power plan High Performance or Ultimate (since I think this is what you are using).
See what frequency it shows in each of your cores in HWInfo64.
Then go to BIOS and enable SpeedStep and try again.
If it still doesn't go beyond 3.3, enable C-States in BIOS and Windows in the power plan (demote = 40% and promote = 60%).

My CPU is 3.5 base and 3.9 turbo. All my cores work at turbo speed while in High Performance power plan.

There is no diffrence between High and Ultimate power plans,i use ultimate,i did enable "Intel(R) SpeedStep(tm)",set demote and promote like you said,still no difrrence i will provide screenshot,also wich of the c-state i should enable?

3.9GHz is only when 1 core is being utilized but for all of them it should be 3.6Ghz make sure you on high performance power plan

i am still no diffrence.

this is not the default high performance power plan, the power plan you using probably have something wrong

also i am now with default so its nothing to do with power plan.

Enable all states except C1E, like in here:

See screenshot

And see if they are working in HWInfo64 in C-State Residency. Cores should be in C7 most of the time.

Your cores are at 3.6 so turbo boost works, it just isn't reaching 3.9 full speed.
