As said in the title, my 4790k is only running at 3,8ghz clock speed, and isn't affected by turbo either. Turbo is turned on in bios, and the clock is set to 4000mhz.
It did this since i installed it, and it was fine since the stock cooler was bad, so i thought it was helping, but now that i installed my h100, it's still doing it.

What is causing this, and how can i fix it?

It won't clock to max turbo unless you are stressing the CPU enough, are you running CPU intensive programs and it still only goes to 3800 max? Your screen shot shows the range to be 8-44 multiplier, meaning most likely you just aren't stressing the CPU enough to require it to go to x44.

When i play GTA, it doesn't do it, and cpu usage gets pretty high, and shouldn't it be at 4ghz default anyway?

Just disabled the powersaving mode for idle, now it's at 4.4ghz all the time, aswell as core voltage is increased, yet i didn't overclock it? I have uninstalled ai suite 3

Install it? That's nothing to install.

@op, I'd advise you to just disable turbo at all and dial the multiplier up to what you want (4.2=stock, 4.4 slight overclock, 4.6 little overclock, 4.7-4.8 high overclock) and set the voltage to a constant 1.3v. When 4.8ghz crashes, use 4.7ghz. If that crashes too, 4.6ghz etc. Once it's stable lower the voltage in little steps until it becomes unstable.

If you just want it on stock, 4.2ghz with 1.175v vcore should (not guaranteed) work.

Stock is 4.4Ghz. You really shouldn't need to mess with any of your settings, if you want to try to lower the voltage to get better temps that is fine (just do it a little at a time till it is no longer stable then put it back to where it was last stable), but leave everything else alone unless you feel the need to clock your CPU over 4.4Ghz.

A utility that is not "Built in" the OS but is download via windows update when a Intel X generation series is installed as speedstep does not work with AMD processors so if it was built into the OS it would cause conflict.
Please don't reference Wikipedia as a reference. Anyone can write it.

I don't understand where you are getting this information. It is built in to the OS just like AMD Cool 'n' Quiet. There is no conflict.

Ok how about this one then? http://www.intel.com/cd/channel/reseller/asmo-na/eng/203838.htm

Software/Drivers: No specific software or driver updates are currently required. However, it is recommended that you always have the latest drivers for your system hardware.

As single core turbo, with all four cores in use 4.2ghz is stock clock.

"No driver updates are required"
A system update is still required.

Where are you getting this info? Any sources?

It is supported by default from Windows XP and newer.

Summoned here to adjudicate onsomething I am certainly no expert on so I'll just ask both sides of the argument to put their evidence up so the OP (who seems happy now anyway) and future readers can make an unbiased judgment.

Thank you, goodnight and as we humourists say on this day of the year - May the 4th be with you! 😀

There is no argument. Hjgrove seems to think you have to install something for Intel SpeedStep to work. This is simply not the case as it supported out of the box in Windows since XP and is supported by all other OSs by default.

If you are installing something to use SpeedStep, it is most likely malware of some sort. Sounds like they were tricked into installing something through second hand information out of ignorance on the subject.

Bit late to the party XD
I am not saying you have to install SOFTWARE as Sinxar thinks but a windows update is required as most motherboards have it in the BIOS itself but it must be activated in the OS, back in the days of XP you use to have to do this:

1.Download and run the latest BIOS update for your motherboard. Check with your motherboard manufacturer to ensure their latest BIOS contains support for Enhanced Intel SpeedStep® Technology.


2.Ensure Enhanced Intel SpeedStep Technology is enabled in your BIOS. For Intel desktop boards, the Intel SpeedStep Technology option is under the "Power" tab and labeled "EIST." Ensure it is set to "Enabled."


3.Ensure your OS has support for Enhanced Intel SpeedStep Technology. For Windows XP SP2 operating systems, install Windows XP SP2 if you haven’t already done so.


4.Finally, Enhanced Intel SpeedStep Technology must be turned on in the OS. Currently, for Windows XP SP2 operating systems, Enhanced Intel SpeedStep Technology by default is off. To turn it on, do the following: a.Under "Control Panel," open "Power Options."
b.Under the "Power Schemes" pull down menu, choose one of the following: 1.To turn Enhanced Intel SpeedStep Technology on, select "Minimal Power Management" power scheme.
2.To turn Enhanced Intel SpeedStep Technology off, select "Always On" power scheme.
"http://www.intel.com/cd/channel/reseller/asmo-na/eng/203838.htm"

But this was a pain so in the more recent OS when the Intel CPU driver is installed via the windows update service for the first time speedstep is automatically turned on but depending on your revision of the OS you might already have the latest drivers installed but this is unlikely.
Which is my point, speedstep needs to be supported by the BIOS and also needs to be activate on the OS which on newer OS is done via a windows update service when the driver is first installed.
