Turbo Boost on Intel Core i7-3610QM processor does not seem to work

[idata]

A year ago, I bought an ASUS G75VW-T1066V laptop with an Intel Core i7-3610QM processor.

I recently installed the Intel Turbo Boost Technology Monitor 2.6 because I was curious how Turbo Boost works.

But under no workload, and I tested many different kinds, never ever did the Turbo Boost Technology Monitor indicate anything other than either the green dot or 2,30MHz.

The Intel specifications (http://ark.intel.com/products/64899/Intel-Core-i7-3610QM-Processor-6M-Cache-up-to-3_30-GHz http://ark.intel.com/products/64899/Intel-Core-i7-3610QM-Processor-6M-Cache-up-to-3_30-GHz ) say that this processor has a "Clock Speed of 2.3 GHz" and a "Max Turbo Frequency of 3.3 GHz" and "Intel Turbo Boost Technology 2.0".

The Intel Processor Identification Utility also claims that this processor supports the "Enhanced Intel SpeedStep(R) Technology: Yes", which I take as meaning "Turbo Boost Technology: Yes".

CPU-Z and Speccy from Piriform are silent about the presence or absence of Turbo Boost.

I have searched on the Internet:

• some say that Turbo Boost must be activated in the Bios; but nowhere in the Bios do I find any parameter that could concern Turbo Boost
• others say that Turbo Boost is used only when the operating system (W7-64) requests execution in a "higher performance state (PO)"; but in "Power settings" I did request the highest performance.

My questions: do I have a faulty i7-3610QM processor?

Or do I have to activate something so that Turbo Boost becomes operational?

Hello S Ulmer,

Based on your processor specifications it was designed to run up to 3.3 GHz with Intel ® Turbo Boost Technology.

This feature is enable by default in our processors, however, depends on the laptop manufacture, they could disable this technology if they want to.

In our motherboards, you can find the Turbo Boost technology feature on the BIOS, under the Performance tab>processor overrides. There you are able to disable it or enable it. However, I suggest you to check with the laptop manufacturer where this information could be found in their BIOS.

Hello Silvia,

No need to search for the Turbo Boost technology feature in the BIOS..

The problem was solved by Pierre Romani /message/192265# 192265 http://communities.intel.com/message/192265# 192265 :

click on start button, type msconfig in the search bar, then press Enter, then go to start, advanced options and uncheck the number of processors and memory limit.

Thanks a million, Pierre.

Not only did this simple procedure enable the turbo boost function, but it also brought back the 4th core of my i7-3610QM processor which did not work before.
