Test cpu speed turbo boost

I like to monitor my system and keep an eye on performance and temperatures to better understand the systems operation. My MacBook Pro case gets hot in a non-repetitive manner so I thought that the CPU might be using the Intel turbo boost technology and that was causing the system to get warm but I can' t find out what the CPU's speed or mode is in OS X. What utility does Apple or Intel supply to monitor this feature? I know windows has a Intel Turbo Boost Monitor application, What are we using here at Apple.
Thanks

Likely your integrated grpahics.
Look in your System Preferences > Energy Saver and uncheck "use graphics switching" this will use your GPU instead of the CPU for graphics and calm down your CPU temps and readings.

Experiment and conclusion on notorious Bios and turbo boost related issue.

Hi everyone,
Like everyone here, I suffered from the turbo boost issue and I decided to find a practical way to solve this problem,so .I conducted some experiments trying to find out the relationship between power strategy, graphic type, booting power source and the CPU frequency.. Here are my results:
Variable: Power strategy for AC/BAT: Max/Balanced, Max/Max(didn't try for balanced AC power strategy)
Graphic type: Integrated, discrete and Nvidia Optimus
power source when the machine booted(BAT,AC)
Testing model: W520 42762QU i7-2720QM Quodro2000M 16G Crucial M4 128G, 500G HDD, BIOS1.30
Testing programs: Intel Turbo Boost programs and CPU-Z

Notice the '800-2400' state, it is a special situation when CPU-Z occationally gives me a speed of approx 2400 when I tried some head-load programs, which lasted about few seconds and the frequencies went back to 800 or 1500(in most cases, 800) when I closed the program.
Conclution:
1. power stratagy will not influnce the cpu frequency.
2. booting power source and graphic types will do.
3. I'm sick and tired of pluging and unpluggin my W520.
4. I'm not a fan of Nvidia Optimus.
5. Lenovo did a terrible job on this issue.
6. I expect a same result for Bios 1.26
Practical solutions:
1.When you need a powerful W520, use Discrete graphic and plug your AC while booting.
2, For a longer battery life, use integrated graphic, and if you wan't to plug the AC, please turn off your machine and boot again.(not rebooting!)
Thank you for reading my post and sorry for my bad english

SomeOtherGuy:
Thanks very much for keeping us all informed about the "work in progress" on the BIOS and the Turbo-thing. That is thoughtful of you and will (hopefully) cut down on the amount of carping and complaining about this issue.

Re: helix CPU speed stuck at low clock speed

Admin edit - Reorganizing this thread slightly as we are actively investigating the symptoms being discussed here. Several different low end clock speeds of 600-800mhz are being reported capped under a variety of circumstances - sometimes cold boot, sometimes after suspend / resume or dock / undock
motku wrote:
Same here (helix ci7), after suspend and wakeup when CPU slows down ist get stuck at 750MHz and dose not recover untill reboot.
Before the BIOS update I could unplug the AC adapter and work with full speed on battery.
I have the exact same issue. It is quite annoying.
Solved!

Mark, theres more.
I found a "pseudo workaround" of this problem and hope this could lead to the real workaround.
What helped - installing win7, lenovo power manager, change power plan to other and change back to previous)
I tried to do some research and what i found:
In normal Lenovo power manager wheres 2 options in power plan:
System perfomance (Maximum turbo, Turbo, Balanced, Low) (lets call it PERF) and Optimise fan control to (Maximize perfomance, Balance all parameters) (lets call it FCNTL.
In theory FCNTL must control only fans, like table of data cpu temperature/fan speed. But in reality it affects CPU speed.
Only way to make PC always select speed from lowest to highest is to set PERF=Maximum turbo or Turbo, FCNTL=Maximize perfomance.
Lets go through options how they really works in practice:
PERF
Maximum turbo and Turbo are equal, means highest speed for CPU with turbo boost. The level of turbo bust is always maximum, Turbo didnt mean "slow turbo boost".
Low - cpu always at lowest speed 800mhz - thats ok.
Balanced - this option works a little crazy. In some situations it means "maximum cpu till 63C", in some situations it means "lowest speed, temperature doesnt matter. Why is it working in different ways but in same settings i dont know.
In theory Balance is something like "from lowest cpu speed till normal cpu speed, no turbo boost", but it doesnt work like that at all.
FCNTL
Maximize perfomance - in theory it must be "try to keep CPU on lowest temp when high load"
In practice its like "Balanced in PERF" - logic is unknown.
Balanced - the same, logic is unknown.
Unknown really means, that when i, for example, setup PERF=Maximum turbo or turbo and FCNTL to Balanced, sometimes it works in full speed and sometimes not.
Maybe there is logic, but it tottaly unknown to users.
The bad thing is that theres no way i can set mode "always run cpu from lowest speed till highest speed without turbo boost, 800-1800mhz".
By the way, there is some error in Lenovo power manager - when i change options in power plan and click "apply", sometimes they a apply, and sometimes not. If not, i need to select other power plan, and then select the needed one back.
Now about how this all can happend. I'm not shure that i'm right, but logically it is:
In Lenovo power manager theres option called "Optimise fan control to". And, there is NO such option in real windows power plan, so, it can be only changed through Lenovo power manager. As i see, this option affects maximum cpu speed. So, lets say, if this option is "damaged" some way, theres no way it can be fixed in windows 8, because Lenovo power manager for windows 8 has too few options, and native windows power plan editor doesnt have this option at all. So, when i done "something" in Lenovo power manager for windows 8, it changed that setting and all ruined.
Sorry for my bad english once more, hope you can understand what am i trying to say. Looks like we have 1) an error in power manager for win8 and 2) incorrect power option logic, or "specific" logic without a manual.
The strange thing, that in BIOS we have this options too. But changes in BIOS doesnt affect this at all.
P.S. by the way, when i got my helix, dock battery was having "wear level" = 1%. Now, after 6 days (battery info 5 cycles) it has "wear level" = 2%. Is it normal, or battery is bad?

Msi gx 623 no turbo boost

hello everyone,
i have my msi gx 623 laptop for over the years now, at the begining for like 8 months everything was ok, with turbo off cpu speed was almost 2.0MHz with turbo on cpu speed always jumped to over 2,3MHz.
Now for last few months i've noticed that my turbo button doesn't boost cpu while playing games.
this one screen was taken with turbo off
and this one with turbo on
anyone have any idea what can be wrong? as you can see, all what turbo does is rises cpu temp nothing else.
im runing win 7 x64 and bios wasn't updated at all

Quote from: Bas on 13-August-10, 09:32:33
As I said before, put W7-32bit on it, unless you have specific 64bit software you must run, as I do believe SCM doesn't function.
32bit software with hardware control won't work in 64bit windows!
Nor does any 32bit program benefit anything being run in 64bit Windows.
To say brief: Do not run 64bit Windows if you don't know why you run it.
i run 64bit because 32bit doesnt use all of my 4gb rams, well at least it didnt one year ago.
btw how can you explain why i had no problem with win 7 64bit and turbo boost 4-5 months ago?
here is some proof that scm doesnt have problem functioning on 64bit, the only thing that doesnt work is that cpu speed doesnt boost with turbo on

Hyper-V stopped turbo boost and cpu park on my intel 4702mq processor?

Hi I just got my lenovo thinkpad e540(core i7 4702mq ,256 hyper-x ssd, nvidea geforce 2gb...)
I installed windows 8.1 and server 2012 r2 to separate personal and business use.
The cpu was running at many speeds to preserve battery life (between 0.7ghz and 3.2ghz on turbo boost). After installing the hyper-v role, the speed in task manager is stale at 2.19ghz and
all the cores are not being parked even when the system is idle, is this a bug or that's just how virtualization work??
Thanks!!

Quote from: NovJoe on 22-November-09, 01:24:35
Performance mode probably means having higher voltages or higher "optimized" settings to run the system. Fail safe mode already spelt out its intentions to keep the system from failing.
For details, you can contact MSI for more information.
As I stated in my first post, I carefully went through all of the BIOS settings and the only thing I could find different between 'default' and 'optimized' is the setting for 'Intel Turbo Boost'.
I will post a question on the BIOS board about any other differences, but until then my original question remains...
...does anyone know of any problems (and hopefully FIXES) with the P55-GD80 and Intel Turbo Boost?

Speedstep or Turbo Boost and Logic CPU Meters

I'm currently weighing up selling my remainding outboard synths and going the plugin route, so last night i loaded logic up with as many plugins as i would normally use in the equivalent of hardware audio tracks to get an idea on CPU Usage, Heat build up etc. (I run on a macbook pro in clamshell to external monitor).
Just to note, i don't normally run with the CPU meter displayed so this is all quite new to see what's going on under the hood, especially as i was making a point to watch it.
What i noticed was that the CPU meter went up very quickly to about 20-30% across all cores after the initial plugins that i loaded up.. But after that point i could load several audio units and record with them, yet they were using nowhere near the same kind of overhead the initial few used.... Dare i say it, they were hardly noticable on the load.
Now, i know that intel processors have had speedstep in the past which would slow your cpu down until the demand was there, and i'm aware that the modern cpu's have Turbo Boost which increases the core speed if required.
So, what i'm curious to know is that do plugins generally cache and have less draw on a system in multiples, or is this a case of my CPU ramping up it's capability the more i pushed it?

hey fmortz,
could you go to > http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-70498

Green Power CPU Phase Control + C-STATE + Turbo Boost ?

Does anyone know if we can turn on MSI's Green Power CPU Phase Control + Intel C-STATE + Intel Turbo Boost in BIOS all at the same time? Any problems with doing this? Does MSI's Green Power CPU Phase Control override or conflict with Intel's C-STATE? And will Turbo Boost kick in if turned on when a core needs it even if Green Power CPU Phase Control and C-STATE are switched on?
I really like the idea of the PC running cool and quiet when doing lite work, but would like full power on demand as well.
Thanks.

I'm using Intel speedstep (EIST) but i disabled c-state because this brings a unstable PC for me.
I'm using also the greenpower genie and it works very well.
When i don't need the power my PC falls back to 50% 2154MHz (this you can choose in the energy configuration of windows), when i play games or decode movies it goes up to 100% 4130MHz. And it is stable as a rock tested 24/7 prime 95 and OCCT and Intel burn test.
My settings are=
Eist enabled
Turbo enabled
C-state disabled
Greenpower auto
My CPU temp in idle is 24° cores 38° and this on aire (room temp 21°-22°) Load 100%=CPU 60 and cores 70°-72° ( prime stressing), gaming CPU 42°-45°.
For more info on my sys. follow link and see my overclock and voltage settings.http://www.hardware.info/nl-NL/usersys/cm9xZ51mk2yd/view/
I also changed cpu skew and ioh skew to 200ps so i don't get BSOD that says :cpu did not receive clock on time , but this is only necessary when i go above 178 MHz BCKL.

Does the 13-inch: 2.5 GHz 2.5GHz dual-core Intel Core i5 Turbo Boost up to 3.1GHz internet speed the same as the 13-inch: 2.9 GHz 2.9GHz dual-core Intel Core i7 Turbo Boost up to 3.6GHz

does the 13-inch: 2.5 GHz 2.5GHz dual-core Intel Core i5 Turbo Boost up to 3.1GHz internet speed the same as the 13-inch: 2.9 GHz 2.9GHz dual-core Intel Core i7 Turbo Boost up to 3.6GHz

The retina MBP will be faster than the conventional one on boot and shutoffs as well as very demanding CPU/GPU intensive applications. As far as web browsing , text editing and other non-CPU intensive applications there will be little if any difference between the two.
If you install A SSD in the conventional MBP, it will be faster than the retina due to the faster CPU. Note also that the conventional MBP can have up to 16 GB RAM installed. The retina is restricted to a maximum of 8 GB.
You will have to weigh the differences in the display, speed, form (weight) and flexibility as to how they suit your needs. All I can do is to and highlight the differences.
Ciao.

MBA2012 cpu multiplier wrong and no turbo boost in Windows7

MBA2012 Corei 7 2.0GHz/ MEM 8GB / SSD 128G.
core i7 3667U, it support turbo boost, max multiplier 3.2GHz (x32, 2core), or 3.0GHz(x30, 1core).
but check cpu-z 1.60.1.x64, it reports cpu multiplier x8 or x19.
core speed does not rearch 2.0GHz(x20) and can not turbo boost.

It is assumed in the model CTO in the initialisation of the MSR in EFI, is to set the Target P-State and 19 at the time of turbo boost, and the root cause of the bug (I originally set 32 is correct).
As a temporary workaround, in the application of the Throttle Stop, but it was confirmed that Turobo Boost working effectively, then, I tried to examine the state of the MSR at the before and after application of the Throttle Stop.
As a result, the following was found.
• The CTO model EIST, Turbo Boost is enabled.
• However, in the CTO model, Target P-State is closed when the Turbo Boost is set to 19-fold. Therefore, (Current P-State) can not be set to at least 19-fold magnification of the CPU.
• When you execute the Throttel Stop, so that can be set to 32 times the Target P-State of Turbo Boost, will be able to raise up to 32 times also (Current P-State) magnification of the CPU.
In fact, before and after execution of the Throttle Stop, appears similar to the following and see the state of the MSR. (The value of the MSR, Save Report(.TXT) of the "About" → "Tools" of CPU-Z in the, you can see)
CPU Throttle Stop before) cpu multiplier 19 (max cpu multiplier 19)
MSR 0x000001A0 0x00000000 0x00850089
MSR 0x00000198 0x00001CD2 0x00001300
MSR 0x00000199 0x00000000 0x00001300
⇒ enable EIST, enable TurboBoost, the current P-State 19, the target P-State 19
CPU Throttle Stop after) cpu multiplier 30 (max cpu multiplier 32)
MSR 0x000001A0 0x00000000 0x00850089
MSR 0x00000198 0x000021A0 0x00001E00
MSR 0x00000199 0x00000000 0x00002000
⇒ enable EIST, enable TurboBoost, the current P-State 30 , the target P-State 32
From the above, CTO model, at the time of initialization when the switch to Windows, it would have been set to 0x1E (0x00001E00: DEC
19) is target Performance State Value is IA32_PERF_CTL of MSR in the BootCamp is a cause of trouble, 0x20 (0x00001E00:DEC 32) you can determine it because it does not, and has been a state that does not increase the magnification was also an attempt to invoke the turbo boost when under load.
Core i5 In the standard model, so go up 26 multiplier, probably should be the value of the following.
MSR 0x00000199 0x00000000 0x00001A00

How to boost nokia e63 cpu speed

hello, please i am wondering if it is possible to boost the cpu speed of nokia e63, become its usually slow when performing various task like 1. When installing an application 2. When opening some big third party applications like opera mini, whats app, and some games 3. When removing an application, these are the areas where i,ve noticed nokia e63 being slow

Go to Solution.

Try closing apps which is running in the background. Clear browser cache and uninstall 3rd party applications which you don't use. Turn off theme effects. All this could affect the "speed" on your phone in a positive way.

10.4.10 boosts CPU speed by 130mhz !?!

Hi,
After installing the Mac OS 10.4.10 update my iBook 1.2ghz now thinks it is... 1.33ghz!
Am I the only one?
In the many years of being a Mac user I have never had this happen before, and it 'appears' that know one else has reported it happening either.
Not that I am complaining!
But really, I have checked and double checked, and the fact remains that 'About This Mac' and System Profiler shows my CPU speed as 1.33ghz now - has the update over-clocked my machine?
When I get a moment I will run a benchmark to see if that is the case, or whether the update is (more likely) just reporting the wrong speed...
Let me know if you have experienced this
braeng
Mac OS X (10.4.10)

Ok, I've just run XBench, compared the results with other users iBooks, and the conclusion is...
About This Mac is lying.
I had, and still have, a measly 1.2ghz
I feel like one of those kids who buy's a old 3-Series BMW and then sticks a M3 badge on it to look cool.
Anyway, I would still like to know if anyone else has had this weirdness happen after the update.

Core i7-2720QM on Macbook pro 2011: Turbo Boost doesn't work! It's possible?

I test my core speed with MacCPUID that show real time cpu frequency. I try it in normal condition and running extreme application. Everytime my cpu frequency is something like 2.199 - 2.200 but never more than 2.200 ghz.
So I have to think that Turbo bost is not active on macbook pro and all the things in apple website about this feature are false!
Is it possibile? Who knows something more about this?
Greetings,
Stefano

Yes, there is Turbo Boost active on all MacBook Pros. There is no real way to measure turbo boost unless you're in BootCamp, using Intel's Turbo Boost Monitor. The Intel website states that not all CPU measuring software will correctly display the turbo frequency because it's either not current, or doesn't support turbo boost. If you have BootCamp installed go ahead and search Intel Turbo Boost Widget. download, and install it, this will give you correct results. You can't really measure turbo in OS X.
