How does the Turbo-boost works on the Intel i7?

Just bought the new MBP Retina and would like to know how the Turbo Boost works in my processor. Is it a regular upgrade like buying a new processor or is it something I could menage at the settings and have it boosted up?
Thanks,

Intel's definition:
Any of the following can set the upper limit of Intel Turbo Boost Technology 2.0 on a given workload:
Number of active cores
Estimated current consumption
Estimated power consumption
Processor temperature
When the processor is operating below these limits and the user's workload demands additional performance, the processor frequency will dynamically increase until the upper limit of frequency is reached. Intel Turbo Boost Technology 2.0 has multiple algorithms operating in parallel to manage current, power, and temperature to maximize performance and energy efficiency. Note: Intel Turbo Boost Technology 2.0 allows the processor to operate at a power level that is higher than its rated upper power limit (TDP) for short durations to maximize performance.

D20 with Xeon Processor E5520 - Intel Turbo Boost

Hi Eric,
E5520 CPU support "Intel® Turbo Boost Technology", how it work under D20 ? any s/w that we can monitor it ?
From the D20 BIOS seems do not have setting relate to "Turbo Boost" .....
Any idea that we can can know it will work under D20 ? or say under the O.S. ?
Regards,
Cody.
Moderator edit: Added detail to subject.

like i said, that's the only app i know about. if it doesn't work with xeon processors then i can only suggest contacting intel and requesting an update.
to me, knowing what turbo boost is doing at all times would be like installing a tachometer on a toaster. it'll be entertaining for the first few pieces of bread but eventually you'll get tired of watching your toast pop up.

Mobo not allowing Intel Turbo Boost

Hey,
I build my own pc like 2 month ago and I'm experiencing problems with Turbo Boost. It was enabled when I got it and after a few days it was gone. The whole option wasn't there in the bios. Later i flashed the bios cause i messed something up and it was available again! So I enabled it again and now It isn't available anymore. Do any of you guys have an idea how to fix this?
CPU: Intel Core i7 4770K
Mobo: MSI Z87-G45 Gaming

Nope it won't.
Leave voltages etc at Auto as CPU should handle this without modifications.
However if you're running stock cooler, run an Intel Burn Test once you change the clock to see if it doesn't go too high than it does with the stock speed.
I am running my non-k i5 4670 at 3.8ghz and I had to manually change the speed, as there was nothing like Intel Turbo Boost
On 3.5 ghz i reach max 90 degrees while stressing :/
So I don't think 3.9 is reachable on stock cooler right?

turbo boost is just enabled unless disabled in the BIOS. There is no way to overclock your laptop. You can install this little app to track the turbo boost and be sure it is working:

HP g62-a60EM Intel Turbo Boost Technology Driver problem

Hello!
When I try to install Intel Turbo Boost Technology Driver from the HP solution&drivers page i get this error: This computer does not meet the minimum requirements for installing the software.
Can you assist me with solution how to fix this problem? Before I changed my OS from Windows 7 Professional (64-bit) - English to Windows 7 Professional (64-bit) - Slovenian I had no problems.
Sorry for my bad English.

Dragan

dmarinov,
Short answer is you do not need the driver. The driver is intended for laptops using the same CPU but integrated GPU only. Since your PC has a discrete GPU (ATI), the TBT driver is not necessary.

Qosmio X500-134 - Intel turbo boost issue

Toshiba stated that Qosmio X500-134 with the standard clock speed of 1.73GHz with the intel processor can get a clock speed of 2.93GHz with intel turbo boost.
I have downloaded and installed the intel turbo boost monitor widget while running loads of applications at once and still turbo boost does not start or work :S,
There is no feature to enable this in the bios which I have the latest version 2.60,
I would like help thanks.

Hey,
As Akuma wrote, Intel turbo boost will only be activated if its really necessary and the application requires more CPU power. Otherwise the notebook will still run with lower CPU speed.
So test it with a high CPU usage application again!

If you look on the second row, you see that it says turbo boost up to 3.6GHz.
Please help me, as i want a faster computer

It works when it needs to permitting power is available, and it isn't too hot basically. You shouldn't need to do anything.
From Intel:
Intel Turbo Boost Technology is usually enabled by default. You can disable and enable the technology, only through a switch in the BIOS, there are no other user controllable settings. Once enabled, Intel Turbo Boost Technology works automatically under operating system control.

MSI X58 PLATINUM, the latest bios and how to enable turbo boost

1) Wich motherboard is ? MSI X58 PLATINUM or MSI X58 PLATINUM SLI ?
2) What is the lastest version Bios and where can i get ?
3) How to enable turbo boost in this motherboard ?
4) Thanks so much guys.

My bad. The obvious lack of your self research got the better of me. I do not take helping, if I can, lightly. This is new technology, & a lot of expertise is in short supply. I downloaded the manual on this board & read the bios section, & in CMOS Setup, you should find an "Enable" setting for Turbo Boost. If you don't, please contact MSI Tech Staff @ http://ocss.msi.com.tw Also, (in your manual), is a reference under "Intel Turbo Boost Tech", which clearly states "for further information please refer to Intel's official website". By your original post, CPU-Z says it's an SLI? What did you buy? Does it say on the retail box? At MSI's website, the X58 Platinum (not the SLI), has version 1.0 bios offered in three global region zip files. M7522v1.0 Euro.zip, M7522v1.0 ASIA.zip, & E7522v1.0.zip. J.T.N. is correct, the SLI board takes something else. Are both boards bios's compatable? I have no idea. Recommend step one as to confirm with MSI what board you truly have & go from there.

Z87-G45 BIOS 1.2 Disables Intel Turbo Boost?

I just installed a new Z87-G45 with an i7-4770k. I installed BIOS 1.2 after getting the system running.
I wanted to test that the Intel Turbo Boost was working, so I went to download Intel's Turbo Monitor, but they helpfully let you know it isn't compatible with 4th generation I-series processors. So I downloaded the Intel Extreme Tuning Utility, hoping it would show the CPU frequency live. It shows the CPU frequency at a constant 3.50Ghz, although I don't know if that means Turbo isn't working or the utility just doesn't do realtime frequency monitoring (but then why does it graph it?) The option to enable or disable Turbo Boost is grayed out in the ETU.
I went into OC in the BIOS to find the Turbo setting and make sure it was turned on... and found out there was no Turbo setting. Intel Turbo is not located where it is described in the user guide for this mobo. So I dug around the OC menu until I found OC->CPU Specifications->CPU Technology Support; that screen shows Intel Turbo Boost: N/A
I feel like there is something very wrong here. Anyone know what's going on?

Froggy: Yes, brought it over from a Gigabyte board with an i7-860 (I do a lot of video editing and moving from the 860 to the 4770k cut down the time it takes to render an effects heavy video by more than half! Getting turbo working shaved another few minutes off of the render time. For the video I used as a benchmark, the render time is down from 60 minutes to 24 minutes ) Honestly I don't remember if the Gigabyte board had AHCI enabled or not, but since Windows won't boot with it on now I'm guessing it wasn't on before.
Bernhard: There is a very simple registry change you can make in Windows 7 to enable AHCI: http://support.microsoft.com/kb/922976?wa=wsignin1.0 I tried the Fix-It tool and manually verified the registry change, but it still isn't booting.
More specifically, the system hangs at the Windows logo. This also happens when trying to boot into safe mode. It always stops after loading the same file, which I looked up and found was an Avast file, but I tried uninstalling Avast and it just hangs after a different file. I installed the Intel chipset drivers that came with the motherboard (which appear to be the latest ones) but don't see any AHCI driver listed under device manager. There is an Intel Rapid Storage Technology download on the MSI page for this motherboard (http://www.msi.com/product/mb/Z87-G45-GAMING.html) but it is for 7-series boards and won't install on my system (I'm not sure the RST driver is even what I need, as it seems more targeted towards RAID, but it came up searching AHCI). The latest RST driver from Intel's download page won't install either ("Platform not supported").
I can't find any other AHCI drivers on the MSI CD. I'm not sure whether they would even show up in the device manager while the mobo is in IDE mode, or only in AHCI mode. If you guys happen to know anything else I should install I'd appreciate it.

W520 Turbo Boost works only after entering Setup (BIOS 1.34)

Hi there,
similar issue but not quite fitting the thread about Intel TB missing in Battery mode, I can reproduce the following BIOS/Windows bug:
- boot the system without entering BIOS straight to Windows 7 : Intel Turbo Boost not working (i.e. frequency dynamically changes between 800 and 2500 Ghz)
- boot the system, enter setup, press F10 and save settings (without changing anything), boot Windows: Turbo Boost works
Is this a BIOS or a Windows problem? It is a workaround to get Turbo-Boost always, but quite inconvenient.
Can someone with similar Turbo Boost problems perhaps check if this is a general issue and could be fixed by Lenovo in a new BIOS update?
System: W520 i7-2860QM @2500 MHz, BIOS 1.34 (same problem on BIOS 1.26).

Hi again,
after spending an afternoon with an IBM service technician we isolated the problem. To make sure we switched boards and tested 4 bios version: 1.26, 1.32. 1.34 and 1.35.
Problem can be reproduced and monitored with Intel Turbo Boost Monitor tool and/or CPU-Z.
Turning
BIOS CPU setting: hyperthreading - off
causes undefined behavior of the turbo boost settings. It works for some reboots. It seems to cause problems more often when the NVidia card is running (either through setting GPU to discrete or by using DisplayPort). Sometimes when taking out AC adapter and plugin back in it won't.All in all very random behavior, but 1 in 4 trials it won't work. Also, when the notebook was off for some time, turbo-boost never works on first boot (need to enter setup at least once, then it will work for some time and reboots).
Symptoms:
Whenever Turbo-Boost is not working, CPU goes only to 2.5 Ghz at max.regardless of energy plan settings.
Switching Hyperthreading back on has (so far) solved the isse (both on AC and battery-without-GPU mode), tested successfully with BIOS 1.32, 1.34 and 1.35. Now we have turbo boost but slightly slower single-core simulationn performance. Not nice, but at least there is a workaround.
Workaround so far (until Lenovo has fixed the BIOS): leave Hyperthreading turned on.
(PS: The service issue was marked as "not solved" and will be send a level higher in Lenovo Support - let's see how this will be taken care of).

Locking Intel Turbo Boost on an i7-2670QM?

Hi,
My HP Envy 15-3040nr has an Intel i7-2670QM processor, which works with Turbo Boost just fine. My laptop goes to a maximum of 3.0 GHz when under full load (I render heavy gameplay videos), and underclocks just fine when in energy saver mode.
However, I want to know if it is possible to LOCK the processor's clock rate at a consistently high rate, say, something like 2.9 (or an unrealistic 3.1 GHz, the rated turbo high) GHz, assuming that heat is not an issue (yes, it obviously will be an issue, but let's just say it isn't).
This question was solved.

In simple word NO,
It is a dynamic overclocking rather than a static overclocking, here is more:

Intel Turbo Boost

Can anyone show me step by step (with pictures if is possible) how to enable Intel Turbo Boost from Bios ?

Need your full model number so we can know what kind of BIOS you have and if your CPU is capable of TurboBoost.

How do i turbo boost my 2.7 i7 macbook pro 15" retina to 3.7?

Hello everyone...
...can someone tell me how to turbo boost my 2.7 i7 macbook pro 15" retina to 3.7?
Being quite new to laptops (my G4 lasted me 9 years!) I'm not quite sure what to do or look for.
Any advice much appreciated!
Glenn

Turbo boost isn't user controlled, it's technology that automatically (and dynamically) kicks in based on the usage of your machine. For more information:
http://en.wikipedia.org/wiki/Intel_Turbo_Boost
Or just google, 'Intel Turbo Boost' for tons of resources.

How to Enable Turbo Boost?

I have HP Pavillion G6 (core i5 2430M) .. I want to know how to enable turbo boost?

Intel® Turbo Boost Technology is a way to automatically run the processor core faster than the marked frequency if the part is operating under power, temperature, and current specifications limits of the Thermal Design Power (TDP). This results in increased performance of both single and multi-threaded applications. Intel® Turbo Boost Technology 2.0 takes advantage of the power efficiencies introduced with having an integrated die for processor and graphics. It is also optimized for the new micro-architecture that was introduced with the Intel® Core™ i7-2xxx processor series and the Intel® Core™ i5-2xxx processor series.
