Intel® Turbo Boost Technology 2.0 Download

Intel Turbo Boost is Intel's trade name for central processing units (CPUs) dynamic frequency scaling feature that automatically raises certain versions of its operating frequency when demanding tasks are running, thus enabling a higher resulting performance.
The frequency is accelerated when the operating system requests the highest performance state of the processor. Processor performance states are defined by the Advanced Configuration and Power Interface (ACPI) specification, an open standard supported by all major operating systems; no additional software or drivers are required to support the technology.[1] The design concept behind Turbo Boost is commonly referred to as "dynamic overclocking".[2]
When the workload on the processor calls for faster performance, the processor's clock will try to increase the operating frequency in regular increments as required to meet demand. The increased clock rate is limited by the processor's power, current, and thermal limits, the number of cores currently in use, and the maximum frequency of the active cores.[1]
Frequency increases occur in increments of 133 MHz for Nehalem processors and 100 MHz for Sandy Bridge, Ivy Bridge, Haswell and Skylake processors. When any electrical or thermal limits are exceeded, the operating frequency automatically decreases in decrements of 133 or 100 MHz until the processor is again operating within its design limits.[1][4] Turbo Boost 2.0 was introduced in 2011 with the Sandy Bridge microarchitecture, while Intel Turbo Boost Max 3.0 was introduced in 2016 with the Broadwell-E microarchitecture.[1][5][6][7]
A feature of Turbo Boost 2.0 is that it introduced time windows with different levels of power limits, so that a processor can boost to a higher frequency for a few seconds. These limits are configurable in software for unlocked processors. Some motherboard vendors intentionally use values higher than Intel's default for performance, causing the processor to exceed its thermal design power (TDP).[8]
Some Intel Core X Processors and some newer Intel Core Processors (e.g. 10th Gen Desktop Core i7) support Intel Turbo Boost Max 3.0 Technology. Newer version Windows 10 and Linux kernel support Intel Turbo Boost Max 3.0 Technology.[9]
A similar feature called Intel Dynamic Acceleration (IDA) was first available with Core 2 Duo, which was based on the Santa Rosa platform and was released on May 10, 2007. This feature did not receive the marketing treatment given to Turbo Boost. Intel Dynamic Acceleration dynamically changed the core frequency as a function of the number of active cores. When the operating system instructed one of the active cores to enter C3 sleep state using the Advanced Configuration and Power Interface (ACPI), the other active core(s) dynamically accelerated to a higher frequency.
Intel Turbo Boost Technology Monitor, as a GUI utility, could be used to monitor Turbo Boost; this utility has reached the end-of-life state by no longer supporting Intel processors released after Q2 2013, and is no longer available.[12]
Your CPU doesn't support it! The turbo boost driver was designed for the CPU with the integrated graphics processor. I don't know why we have got the driver on the support website. I have tried it as well but found out it's not for my CPU (Core i7-720QM)..
I upgraded from Windows 7, but I still kept a copy of Windows 7 and all my files on a separate hard drive, which utilizes Turbo Boost Technology to it's full potential of 3.61 Ghz. Yet when I use my Windows 10 hard drive the processor will not go higher than it's standard out of the box speed of 3.33 Ghz.
I have faith that there IS a way to unlock the TB! Its funny, I just switched back to my other WD hard drive and W7 and it's turbo boost all day on the monitor and CPU-Z! But when I boot up my W10 HD its stopped like 75% of the way up the monitor. what a drag.
As I stated in my earlier post I have CPU-Z and its not going higher than 3.33 Ghz. But in Windows 7 I can get it up to 3.61 Ghz with Turbo Boost. So like, it's really not supported on Windows 10? Geez guys what a drag...
I think you need to be more specific here, since the Intel 7 series chipsets can support both 2nd Generation (Sandy Bridge) and 3rd Generation (Ivy Bridge) Mainstream processors.The Intel 6 series chipsets can work with both the 2nd Generation (Sandy Bridge) and 3rd Generation (Ivy Bridge) Mainstream processors.
Given what has been reported here, it seems to me that Intel processors with Intel Turbo Boost Technology 1.0, are the ones that may not have Turbo boost working, when used with Windows 10. Starting with the 2nd Generation Intel processors, aka Sandy Bridge processors, Intel Turbo Boost 2.0 began being used, instead of Turbo Boost 1.0. The i7-975 used by the OP uses Intel Turbo Boost Technology 1.0, and of course an earlier chipset.
Personally, I would never use CPU-Z as a monitoring tool for checking Turbo boost. CPU-Z displays one CPU/Core frequency, which is inadequate for monitoring Turbo boost. This applies to non-over clocked processors only. Turbo boost does not allow all the cores in a processor to run at the maximum Turbo boost frequency at the same time. Normally only one of the processor cores is allowed to operate at the maximum Turbo frequency. Two processor cores can run at one or two "bins" down from the maximum Turbo frequency. When all the cores in a processor are at high load, they will then all operate at the base clock speed of that processor, without any Turbo boost.
If you want see what your processor cores are running at most of the time, use IXTU or HWiNFO64. The latter will show all of your processor core speeds simultaneously in one display,as well as the core multipliers. Windows own processor speed display is also inadequate for monitoring Turbo boost.
Also, I am skeptical that Windows 10 is preventing Turbo 1.0 from working correctly. If it really is, that is more likely due to an out of date Intel Management Engine software being used in the Windows 10 installation. Turbo control belongs to the processor, not the OS. Multi-tasking and multi-threading belongs to the OS and software. Given how long Windows 10 has been with us, are we only now noticing an issue like this? Or is this a new issue with Windows 10 Anniversary?

I heard somewhere that this additional 1GHz is shared between all cores in laptops. If the boost is 1GHz per core it's pretty impressive (over 40% speed up). What does it really look like? How long can a processor run in turbo mode?
Intel Turbo Boost only boosts the speed if the processor is not fully utilized. Their site is pretty vague on details, but I remember seeing that it's designed for when one core is being maxed out while the other cores are sitting idle. If you're using multiple cores, the processor is drawing too much power, or the processor is too hot, then Intel Turbo Boost will turn off and the processor will return to it's normal maximum speed.
Thermal design power The thermal design power (TDP), sometimes called thermal design point, refers to the maximum amount of power the cooling system in a computer is required to dissipate. The TDP is typically not the most power the chip could ever draw, such as by a power virus, but rather the maximum power that it would draw when running "real applications". This ensures the computer will be able to handle essentially all applications without exceeding its thermal envelope, or requiring a cooling system for the maximum theoretical power (which would cost more but in favor of extra headroom for processing power).
In some cases the TDP has been underestimated such that in real applications (typically strenuous, such as video encoding or games) the CPU has exceeded the TDP. In this case, the CPU will either cause a system failure (a "therm-trip") or throttle its speed down.[1] Most modern CPUs will only cause a therm-trip on a catastrophic cooling failure such as a stuck fan or a loose heatsink.
For example, a laptop's CPU cooling system may be designed for a 20 watt TDP, which means that it can dissipate up to 20 watts of heat without exceeding the maximum junction temperature for the computer chip. It can do this using an active cooling method such as a fan or any of the three passive cooling methods, convection, thermal radiation or conduction. Typically, a combination of methods is used.
Since safety margins and the definition of what constitutes a real application vary among manufacturers, TDP values between different manufacturers cannot be accurately compared. While a processor with a TDP of 100 W will almost certainly use more power at full load than a processor with a 10 W TDP, it may or may not use more power than a processor from a different manufacturer that has a 90 W TDP. Additionally, TDPs are often specified for families of processors, with the low-end models usually using significantly less power than those at the high end of the family.
You can record the frequency of your CPU and then see how turbo boost behaves. I would also be interested in that :) Check my answer here (the last picture) how to record the frequency using perfmonThere is something odd with my CPU
You can open a terminal and run grep MHz /proc/cpuinfo. Then open a second terminal tab and run a loop like while :; do :; done. In the first terminal, run grep MHz /proc/cpuinfo again. You should see one of the cores has a higher frequency now:
