Activating Intel Turbo Boost on demand possible ?

I have an Intel i7-4510U based laptop that I use to encode 4K videos on over night .

According to specs this thing CPU can operate at 2.0 GHz as base speed and 3.1 GHz as max turbo speed .

If I game on this laptop , monitoring utilities shows the CPU to be working at 2.8 GHz constantly and for long hours without tiring .

However when I set it to encode videos it sustain base speed of 2.0 GHz the entire time of encoding .

Now I am wondering how to get to control the Intel Turbo Boost so to have it boosting the CPU to as fast as it gets through out the encoding process too , any suggestions will be appreciated .

What is Intel(R) Turbo Boost Technology and How Does it Work?

so basically it has a mind of its own. so does this mean I would just over clock the cpu to 2.8 ghz and call it today ?

You can't overclock an i7-4510U. CPU will boost maximum speed when there is need for it.

Hi,
Turbo boost 3 unless you add a app to it's list it will not work
Just use bios to do what you want to do your bios may have By core usage along with All core or maybe even By specific core
By core usage is best for what you want to do just enter the turbo frequency

TB-3 has security flaws unlikely to be fixed
Think a win-10 update kills tb-3 finally

remove Intel Turbo Boost 3.0...
Here's a proper way to disable the application (with device driver intact).
1. RIght-click on the tray icon, and disable it.
2. Open Task Scheduler and disable Intel Turbo Boost Max Technology 3.0

3. Open Command Prompt and type “sc config ITBMService start= disabled”
4. Reboot.
Now back into bios and disable EIST (Enhanced Intel SpeedStep), and Enable SpeedSHIFT.
F10 to save and reboot.

Thank you all for your participation , again please realize the following :

1 - This is a laptop , and this is a Turbo Boost 2 technology CPU

2 - There are no options in bios to do anything , mind you Intel itself claim this feature is handled by CPU automatically

3 - The feature triggers itself with games and may reach 2.8 GHz speed

4 - The system is able to achieve Turbo Boost speed on balanced and high performance battery power planes

5 - However when encoding videos and while the program encoding them is multi threaded and utilize all 4 threads of core to 95~100% but still the CPU persist to operate at base speed of 2.0 GHz (on both balance dand high performance battery power planes)

The conclusion is :

1 - We can't tam Turbo Boost to work if it doesn't want to

2 - The laptop can achieve the turbo speed of 2.8 GHz when it wants to ...

so I'm getting to see this is an indicator that it is safe to overclock CPU up to 2.8 GHz since it can be sustained for as long as games run .

So my question is , should i just over clook CPU ?

"Activating Intel Turbo Boost on demand possible ? "
No, it is not possible.

Maybe you have not looked in detail for that processor. The 2.8 GHz max turbo frequency is probably for 2 core use, 3.1 GHz for 1 core use.

Mine is an i5-4200M CPU HD 4600 iGPU, so one of that series. The difference with most U series processors is the core voltage is reduced in addition to frequency to reduce power consumption.

The control that you have is the Power/Battery control right side of Task Bar.

On mine the RH end position (Best performance) gives a base frequency 2.5 GHz to 3.1 GHz (max turbo).
The centre position (Better performance) gives a range of CPU speeds up to the maximum Turbo frequency, 0.8 GHz to 3.1 GHz range for mine.
That variation can be seen in the Task Manager running suitable applications.

The iGPU has similar clock speed variations.

You have to bear in mind that there is thermal protection in the CPU/iGPU, so the Best performance setting increases the chances of that happening compared to the Better performance setting because of the higher minimum CPU frequency(base freq).
I have mine set to the Better performance setting(centre position). I can run any test with this and get the same result as the Best performance setting so basically the Turbo boost works well on something taxing but on using Windows or some minor stuff it clocks down to 0.8 GHz most of the time.

Putting that another way the RH end(Best performance) setting just makes it run hotter with no gain, not good for a Laptop.

There are further complications as to where the Video encoding is being done, is it the CPU, iGPU hardware encoders or software, that is what you will have to suss out.

"I have an Intel i7-4510U based laptop that I use to encode 4K videos on over night ."
An appropriately specified Desktop PC would be many times better for that sort of purpose.

Wrong conclusion, that is what you want, as I said there are thermal, hence performance limits built in to the Intel CPU/iGPUs.

Turbo Boost is under the control of the CPU. With the power options you have some control over the parameters under which it will operate but the CPU makes the ultimate decision as to when to activate Turbo Boost and how long to maintain it. Even the OS cannot override this.

The CPU will activate Turbo Boost when this would be beneficial and it is safe to do so. Heat is the major issue here, particularly in a laptop. The confined space, small fans, and restrictions on where they are placed make heat difficult to dissipate. Generally Turbo Boost will only be activated when 1 and sometimes 2 cores are active with fairly high CPU usage. If multiple cores are active Turbo Boost would quickly require throttling back the CPU speed, which defeats the purpose of Turbo Boost.

Overclocking a laptop is a really bad idea. These computers lack just about everything necessary for both safe and effective overclocking. For the previously mentioned reasons controlling heat in a laptop running above rated CPU speeds is very difficult. Many laptops run hot at stock speeds. Manufacturers are well aware of this and for that reason omit the necessary settings from the BIOS. This minimizes failures due to heat and saves on warranty claims. Overclocking a laptop is for experts looking for a challenge. And even then it is more of a stunt than something practical. Overclocking is best confined to home built computers where you control the ratings and quality of the components used.

Hi,
Use max performance power plan.
