Turbo Boost2.0

Icey370

Hi all,

I had bought two laptops and had set them up (programs, updates, etc). However, I then realised that I had the owners names switched around; as there were no personal files on either I just created new administrative accounts on both and deleted the old ones accounts and changed the laptop names around

Both laptops are using an Intel® Core i7-4700MQ (6MB Cache, up to 3.4GHz w/ Turbo Boost) and Im pretty sure it use to state the following when in Control Panel > System and Security > System:
"Processor: Intel(R) Core(TM) i7-4700MQ CPU @ 3.40GHz 3.40GHz"

However, one these new accounts, when I open Control Panel > System and Security > System in the new accounts, it states:
"Processor: Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz 2.40GHz"

Now my question is, is the system suppose to display the Turbo Boosted speed or the normal speed? As I swear it use to state the boosted, but it may just have been me seeing things :rotfl:

thanks in advance for the help

p.s. I do have a factory restore, would it be worth me restoring one and checking it?

one way of turbo boosting is in the bios. This wil always pedd up the procesor, making it hotter, use more power, and cause the cpu to fail quicker.

Often on newer laptops, there is a turbo boost detection built in as if it needs more cpu usage, will automatically boost the cpu. To see this in realtime action, you can download a utility from intel, but it does take up cpu

To be honest it can act as an annoying popup, and if it does not inform you, then it is not worth having, so I chose not having the popup. https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=19105

Which operating system is it? I find Windows can be a bit erratic as to what it claims as the clock speed in the system properties, I've just checked mine and it's showing as 3.2Ghz which is the base speed the processor runs at. If you have Windows 8, the new task manager will show you the actual clock speed the processor is running at if you go to the performance tab and click more details - when mine is idling it's showing around the 1Ghz mark, I've just fired up a video render and it's clocked up slightly to 3.46 Ghz (all cores are mostly active so it can't turbo much). The less cores that are active the more likely the processor will be able to overclock itself with turbo boost whereas when all cores are active it will likely sit around its base speed.

If you're not using Windows 8, CPU-Z should be able to show you the current core speed. If you want to see the cores turbo up you'll need to run an intensive task that doesn't use all the cores otherwise if the machine is idling and not doing anything that needs much power it will try and keep the cores clocked down. Also ensure in your power profile you have it set to maximum performance.

Don't use the tool recommended in the post above - as it listed in the details, it isn't compatible with fourth generation Core processors (Core ix 4xxx models):

Not Supported: This software is not compatible with any Intel® Core™ i3 processors and ALL the 4th Generation Core processor family

I've uploaded a screenshot showing system properties, task manager and CPU-Z with the speeds highlighted on each:

Yeah, the laptops came with turbo boost.

When installing any of the programs I had not recieved any pop-up message pertaining to turbo boost (some of which were quit large)

Im using windows 7 home premium (Im not a fan of windows 8 )

Anyways, what im doing is just launging the windows rating program as that makes my computer work, but mayber it just doesnt want to show the over boost 2.0

thanks both, thats useful information

Running the Windows rating program won't push the CPU, I've just checked it on mine and the CPU sat at just 4% most of the way and under the base clock speed with only brief flickers above that.

thats useful to know, guess I shouldn't judge the load on the fan noise Il try and remember to look at the load next time too although the windows 7 task manager doesnt look anywhere near as nice as the windows 8 :sad: Im sure thats will those other programs will come in handy though

Johnmcl7

It is possible for the fans to be on full but have no turbo boost because if all the cores are active at a high-ish level then the processor won't turbo boost. So you need software which isn't multicore optimised and only uses one or two cores to see the turbo boost in action, I was going to recommend Superpi as it's a very simple little tool but again checking on mine it isn't really pushing the machine much.

7zip to compress a large dir makes my cpu go from 8% to 32% and you can see the extra MHz in task manager on win 8.
