Disabling one processor

Hi,
i'm a little curious about this,
is it possible to disable one processor manually from osx?
Will it consume less power (perhaps half?).
I'm asking this because i keep the macpro on all the day,
but only a few hours i need to work hard with all the 4 cores.
I'm not crazy, simply my energy bill this month was a bit too high and i think the guilty was the macpro.

you can use apples chud tools to disable one or more cores: http://www.versiontracker.com/dyn/moreinfo/macosx/14358
when you install it youll get a 'hardware' or 'processor' prefpane which will let you disable the last 3 cores of the mac. im not sure whether this actually turns them off, but they certainly get no tasks to carry out so it should use less power. you can also keep your work to just the boot drive and any other drives you have in there will spin down, thatll use less power. i cant think of much else to do really.. turn the brightness down on your monitor if its tft, those backlights eat up power. oh yea, and turn off airport and bluetooth as well as the ethernet ports if youre not using them.

  • Why would you disable one processor?

    just curious about the system preferences pane that lets you specify whether to use one processor core or two. why would you set it to one? what practicle application could there be to disable a processor core?

    Developers may need to disable a processor as part of software development. Disabling a processor on a laptop will extend battery life when processing speed isn't critical. May be necessary to determine if one of the processors is defective.

  • I can disable one of my MacBook's two CPUs using the CPUPalette application.  How can I do it under control of a script?

    I can disable one of my MacBook's two processors using the CPUPalette application.  How can I do it under control of a script?
    I want to do this because the MacBook is overheating.  I will soon get it repaired, but in the meantime, disabling CPU 2 is effective at preventing overheating.  Sadly CPUPalette is not scriptable, and it won't remember its setting after the computer is restarted.
    Would it be worth learning about the relevant Darwin API (supposing there is one) and writing a small command-line program for the job?  I am an experienced developer of software using Standard C.
    Comments appreciated.

    i wonder if there is a key that is stuck cause whenever i try to turn it on again after the 60 minute lockout, it says that the password was incorrect and i am locked out for another 60 minutes

  • My dual processor G5 is missing one processor?

    I transported my G5 dual processor 1.8. When I look at my "About This Mac" screen it only lists one processor. When my friend looks at his screen it clearly shows it as a dual processor. I can not honestly say I checked it before. But for sure now it does not say dual. And when I go to the "more information" page it says there is one processor, not two. Can something happen internally to the machine to disengage one processor? Ever heard of this? Please answer offline as well, [email protected]

    It's possible one of the processors has been disabled.
    Look for a "Processor" preference pane in your System Preferences.
    You'll see right away if the second processor was disabled.
    If it's not there, open Activity monitor and watch CPU load a you run a bunch of active programs, DVD, iMovie, garageband, iTunes visuals etc.
    If you see only one processor there, no +100% readings, you got a problem.
    It's possible one of your heatsink/processor combinations came dislogded from the logicboard.
    Open your machine up and gently wiggle each heatsink, you might be able to tighten it down yourself, the plastic cover may need to be removed. It's snaped into place.

  • Disabling AMD processor

    I have a 15 inch mac book pro and it is equiped with a AMD Radeon HD 6770M with 1GB GDDR5. When activated it consumes a great deal of battery power when using applications that do not require it. I was wondering if ther is a way to shut it off and turn it on when needed.

    Do you have a specific question regarding temps?  There are probably thousands of posts here with respect to temperatures, so it would be impossible for us to know which specific one you are referring to.  As the title of this thread is "Disabling AMD Processor", anyone browsing won't know to look for a posting about temps here.  You should probably create a new post for your temp question.  If you just want to monitor your temperature, you can use the free iStat Pro widget which you can download directly from Apple:

  • How to disable one single element in a 2D array?

    Hello,
    I would like to disable one element in a 2D array. its size is constant at least.
    I can change its value by using a 1D array of cluster, but I can't use the property mode easily to disable an element.
    If you have any idea, it will be great.
    Thank you for your help.
    Lolopuf

    Right click on the particular control you want to disable and change the properties on that.  To do it programmatically, create a reference for that specific control and set the Disabled property for that.

  • How do I disable one item in a radio buttons control at run time

    I need to disable one item in a radio buttons control. At design time
    this is possible, but how do I do this at run time? Is this possible? I
    cannot find a property per item

    Use the property "Controls[ ]" - this gives you an array with references of each single button in the radio buttons control. These you can access with property nodes too.
    Hope this helps.

  • Unable to use more than one processor group for my threads in a C# app

    Hi,
    I set my .Net 4.5 (or 4.5.1) App.Config to:

    <configuration>
    <runtime>

    I run my app on a windows server 2012 with a NUMA architecture: 2 x [cpu Xeon E5-2697 v3 at 14 cores each with Hyper Thread activated] => 2 x 14 x 2 = 56 Logical Processors.
    This is TaskManager screenshot:
    My app start 80 threads either from "Thread Class" or "Parallel.For" and in both case it only takes 28 Logical Processors, all from the same Processor Group.
    According to MSDN documentation
    and
    Stephen Toub answer, it should use every Logical Processor of every Processor Group.
    Why does the Task scheduler assign my threads on only one Processor Group?
    I also reported this question to
    StackOverflow which have a lot more information.

    One thing before all, is that I suggest that you think through your security model before implementing it in UCM. You should ask yourself questions like :
    - Is security really based on department ?
    - Why two departments need to have access to the same category of document ?
    - Is it really security that I need or classification ? Is it a problem if Accouting have access to Finance or you just don't want Marketing documents in a finance related search ?
    - Maybe what you want is that finance guys to have access to marketing document.
    Without a clear business security model, it's hard to find a UCM security model as it is impossible to associate 2 security groups to one document.

  • Need to disable one of the select-options in dynamic selection screen

    Hi,
    we have copied the Standard program: RFDOPR00 into Z, my requirement is to disable one of the select-options in dynamic selection screen for ex: Reason code(User shouldnot able to enter anything in it).
    Can anyone please tell me the procedure to do it... I had tried using at selection-screen but it doesnt work as it in 'LOOP AT SCREEN', i am not able to capture the Parameter name(screen-name).
    Thanks,
    Ravi

    Hi,
    Get inside your selection screen, by executing your program.
    Now type /h in the field where you enter transaction code and press enter.
    Now again press enter, this will take you debugger starting from your Selection screen.
    You might be knowing this, still if you are not aware of this, this might be a valuable tip.
    From here , you can trace your Parameter name.

  • Dual 1.8 GHz G5 only running of one processor

    My dad has a Dual 1.8 GHz G5 and had problems in the past, one of the processors went out. He took it to a repair shop and they switched it to run only off one processor. Apparently after they repaired the computer, they didn't tell it to run on both processors. We found out when we went to About this Mac. How do I tell it to run off both processors again?
    G5 Dual 2.7 GHz, 15-inch PowerBook 1.5 GHz   Mac OS X (10.4.3)  

    Nap is a power saving feature.
    The following processor states are defined:
    ■ Run: The system is running at maximum processing capacity with the processor running at full speed.
    ■ Idle: The system is idling; this is the default state. All clocks are running and the system can return to running code within a few nanoseconds. If the system has no work to do, it will be in idle mode.
    From idle, the processor will enter deep nap state when the system is power-stepped to half frequency. In this state, the processor’s internal frequency is reduced to 1/64 of the maximum frequency. The processor frequency is returned to normal on exit from idle. The exit from idle takes a bit longer than the regular idle nap but is still in the nanoseconds.

  • To disable one field of standard sap screen.

    Hi,
    I want to disable one field of standard SAP screen for example
    tran code : MD61
    Field : Version.
    Can Anybody suggest me with simple coding.
    thanks
    naresh

    Naresh,
    I guess this can be done using Transaction Variant SHD0.
    Just try to check the links related to transaction variant.
    1.go to SHD0
    2.give the transaction as MD61     
    3.Transacation variant as zmd61
    4.now press create button
    4.Here you will get to see the initial screen on MD61
    5.Press enter
    6.You will get to see the field attributes in a screen called 'Confirm Screen entries"
    7.There you can make a field as required/invisible/ouputonly.
    Do check other links available in SDN for more info.

  • Turning off one processor with CHUD tools

    So I need to turn off one processor on my MBP running leopard 10.5.4 to solve a sound problem with Myst III Exile. When I switch to just one processor in the processor preference pane the computer slows down, which is normal, but what doesn't seem normal is that there are processing spikes that happen every 5 seconds or so. The computer seems to freeze during these spikes. I'm not running anything out of the ordinary. I have my linotype font explorer running, transmission torrent client running and thats it. Once I turn the second processor on again the computer functions normally with no spikes. Any help would be appreciated.

    Thanks for stating the obvious, does anyone have any intelligent suggestions rather than casual observations?

  • Can inherited events be used with only one processor?

    Hi friends!
    The question is quite simple: I have one parent event and several events which inherit from the first one. Every inherited event has its own properties and also the inherited properties (which have public visibility in the parent class so that the inheritance is automatic). I pass events to the CEP processor but it only works with the parent class and doesn't with the child ones. I mean, I'm using only one processor and only one CQL sentence.
    Is it neccesary to configure one processor for every inherited event?
    Thanks!

    It says the following:
    As you can see there are two input channels which are both connected to the JMS adapter as well as only one processor which is connected to the input channels and to the output channels. It is supposed that each event goes through each input and output channel but it fails and says the following:
    Channels mesEventsOutputChannel and inputPetitionOutputChannel from the same query must have the same event type.
    InputPetition is MeSEvent's child. It inherits all MeSEvent's preperties.
    Does anybody know what is happening?
    Thanks!

  • Core 2 Duo - one processor

    I did a hardware check and it says I have one processor and 2 cores. I thought core 2 duo was two processors - just curious. I just exchanged my Black MB for the 15.4 inch 2.16 MBP.

    no.. its two cores built into one processor..
    which unfortunately isn't as good as having two individual processors.
    its very very similar to your old blackbook..
    except depending on which processor you went for it may be slightly faster.. and because its a "core 2 duo" aka merom chip, it's a little more efficient with the power it has available...
    most people are also saying that they run a little cooler than the core duo aka yonah chips.

  • How to disable one Audio port on MSI MB with Realtek HD Audio

    Hello MIS gurus.
    I have MSI p45t-c51 MBoard with ALC889 Audio chipset. On this board i installed Win XP Pro with Realtek HD Audio Driver 5.10.0.6101.
    On back audio plate i use Edifier 2.1 audio over one of the audio port's and HeadPhones over another one.
    My question is: Is it possible to disable one of the ports so the sound only come from 1 of the audio devices instead of both.
    At this moment, what i do is in the Realtek HD Audio Manager, i set LINE IN for the device i do not want to hear. - Advice if that is bad for the device that is plugged in at that port!
    Thanks to all.
    Regards.

    Just disable the Onboard Audio from BIOS.
