G5 1.8 dual core recognizes only one core

I recently bought a dual core G5. The G5 isn't recognizing one of the cores. Any ideas how to fix it?

I don't usually have this problem, but I'm having it now with a project I'm doing while working off of Access Music's virus logic template. I wonder if there's a setting or something. One core is maxxing out and crashing the system, and the other is completely unused. I'd like an answer .

  • Second mac in cluster uses only one core

    Hello all. For some reason the second computer in my render farm is using only one core out of eight.
    I'm using 2 Mac Pros linked together directly via giga ethernet wire. Mac one is a Quad Core 3ghz. Mac two is a Octo Core 2009 model. Both computers have the same version of FCS3 with different serial numbers.
    In the Qmaster preferance pane: Mac one is set to "Quickcluster with services" with the check boxes for Share and Managed next to "Distributed processing for Compressor" checked. 4 instances selected and "Include unmanaged services from other computers" checked. Mac two is set to "Services only" with check box for Share next to "Distributed processing for Compressor" checked. 8 instances selected and "Include unmanaged services from other computers" checked.
    I hit submit in Compressor, select the name of the cluster from Mac one, then in the Batch Monitor I see the video divied into 10 sections with Mac one handling 4 and Mac two handling one. On Mac two I see that the cores aren't fired up 100%, more like 30% on average.
    I did a test earlier with a dual core mbp, and again only one core. How do I get my Octo core to use all 8 cores?

    Solved the problem. The solution was simple, but somehow went under my radar. On Mac two in the Qmaster preferance pane next to the "Options for selected service" button, the selected service was set to off.
    Duh

  • Oracle utilizes only one core out of 8 core's.

    Dear Team ,
    We have noticed that, in oracle database server Oracle processes uses only one core and that goes to 100% usage remains are at idle possition thats the reason the Oracle performance is very poor some time system haults and needs to be started
    Please suggest if you can have best solution,
    waiting for your valueable response.

It is often slower running processes across CPUs (e.g. 5 processes on 5 CPUs with 15% CPU utilisation per CPU), than running these processes on the same CPU (e.g. 5 processes on 1 CPU for a 75% CPU utilisation). See Non Uniformed Memory Access (NUMA) for some details on why this is the case.
    The kernel deals with CPU scheduling. It decides which process/thread to execute on which CPU. From a s/w perspective, one can code "processor affinity" into your s/w to bind a process or thread to a specific CPU. Oracle only does this with Oracle XE - as this is one of limitation of the free version of Oracle's database s/w. Oracle uses default kernel scheduling for Standard Edition and Enterprise Edition versions.
    Oracle uses the number of CPUs/cores to determine the processor load it can create. It does not force its processes to run on a single specific CPU (with XE being the exception).
    So "blaming" Oracle for what you are seeing? You are blaming the wrong layer in the s/w stack. You are also very likely misinterpreting what you are seeing.
    The #1 reason for poor Oracle performance is shoddy code. Code that you and your cohorts write and run in Oracle. And that is a far likelier candidate to blame for shoddy performance, than blaming Oracle and the kernel's process scheduling across CPUs.
    And you have provided not a single shred of evidence that points to a SMP scheduling issue across multiple CPUs/cores.

  • T440s - i7-4600U CPU - ONLY ONE core operating :((

    Hi,
    I am an owner of Thinkpad T440s ultrabook, which has Intel i7 4600U CPU installed (exact model is 20AQ006BMC - the one with GeForce 730M graphic card).
    Regarding to the documentation on Intel website, this CPU should have 2 cores and 4 threads (Hyperthreading). But when I start CPU-Z utility, it shows me, that I have only one core and two threads available. Same thing displays my process manager in Windows 8.1 - 1 core and 2 logical processors.
    Any ideas, what could cause this problem?
    Thank you.

    I have found review of exact same model (as I know, they differ in few other details like 3G modem etc.): http://www.notebookcheck.net/Lenovo-ThinkPad-T440s-20AQ006BGE-Ultrabook-Review-Update.120211.0.html
    And there is also screenshot from CPU-Z utility and there it shows correctly 2 cores and 4 threads:
    So any idea, what could be an issue? Should I use warranty service? because it looks to me like a broken CPU

    It appears this model came with XP. Did you install Vista or upgrade to Vista?
    Perhaps you need to install or update the Intel Chipset Driver, or install the Value Added Package.

    Why is motion 5 using only one core during heavy renders, even when all other apps are closed?

    coz it uses the GPU to do all the graphics stuff. The cores are only used to process project data.

  • How to use only one core for Macbook Pro?

    I know that Macbook Pro is a dual-core CPU Macbook. I know I can do this by using battery only. But are there any ways that I can turn off one core in the system while keep the power adapter plugged in? Thank you!

    Navigate to /Library/Application Support/HWPrefs and launch the CPUPalette program.
    (If you don’t find it there, insert your Leopard install disc, click on Optional Installs, select Packages, and double-click on CHUD.pkg; that will install CPUPalette.)
    It will display two graphs showing how busy your CPU’s cores are, and let you disable one or more of them. Click on the oblong button in the upper right corner to reveal a settings panel where you can adjust transparency, sample interval and history, and chart format.

  • Only one core working in Core Duo X60

    I bought a 2nd-hand Lenovo/IBM x60 Thinkpad about a year ago on Craigslist. Perfect condition, nice price, all legit-looking, and I'm using it now -- except that the guy had replaced the legit XP Pro with a bootleg installation of Windows7, without saving any backups or making rescue disks or anything. It worked fine and updated and everything, but I didn't want to run bootleg Windows, so I was determined to reconstruct the legit XP Pro SOMEhow. I had various Windows disks (incl. a non-legit install CD some vendor stuffed into my shopping bag) and a full set of recovery disks from my T40 Thinkpad.
    It wasn't easy or quick, and didn't go smoothly, and I don't think I saved detailed notes on all the steps I took, but I finally got it running smoothly. XP Pro, SP3, with the same ID# as on the sticker, and enough updated drivers to run properly. I've been using it pretty happily for the past year, except that the speed has been disappointing. Recently, it's finally dawned on me that I'm only using one CPU core in the 2-core "Core Duo" CPU. That's presumably because the T40 only has a single-core CPU, and I used its XP setup (with some updated drivers, etc.).
    Device Manager says my Computer is an "Advanced Configuration and Power Interface (ACPI) PC", not an "ACPI Multiprocessor PC".
    Other than converting to Linux or buying a copy of XP Pro. . . is there a way I can educate this computer to use both of its CPU cores??
    [Here's more details, and what I THINK I know about the problem:]
    I think the problem is in the HAL = Hardware Abstraction Layer, and I've already tried using XPud Linux to substitute-rename the multi-core halmacpi.dll file from the SPFiles\i386 folder, making it the Hal.dll file in the System32 folder (which was formerly identical to the 1-core halacpi.dll in that folder -- no, not the halaacpi.dll file I expected to be identical). But the computer wouldn't boot Windows afterwards, so I substituted-renamed the Hal.dll file back -- successfully, without having to restore from an image. I'm guessing that there's another file or two that refer to that Hal.dll file that don't match up, but I can't find any advice online other than to re-install Windows. Since I still don't have the "real" Windows install CD for this Core Duo computer, I don't think that's a good option.
    I feel a bit victimized here, because I'm going to a bunch of extra trouble to be legit, but I'm not being treated (by MS or Lenovo/IBM) as a valued customer. (I must have gotten at least 5 or 6 "You're a pirate!" error messages while I was trying to restore the computer to its original legitimate OS!)
    Lenovo/IBM will sell me a new Rescue disk for $50 -- I bought one for an earlier Thinkpad, my T22, IIRC -- but I'm not confident that I'd get joy from that, either. (As I recall, the old one I bought didn't do everything I'd hoped it would do.) Plus, I'd rather not have to reconstruct and reconfigure all my software unless I have to.
    BTW, I've wiped out the traditional IBM Rescue partition I had originally set up and merged it with C:. (I wanted the GBs.) I do still have an image backup of it, and I could restore it (and try using it), but there's no reason to believe that it would help, since it presumably came from my 1-core T40, not from a Core Duo machine.
    Any suggestions?

  • Mathematica 5.2.2 uses only one core

    Using Activity Monitor, I have seen that Mathematica 5.2.2 uses only the second core, even if Wolfram says that it supports multi-core calculations.
    So, firstly, I use only half of the power of my MBP C2D and secondly this could be dangerous for the processor because I use Mathematica all the day for work and this asymmetric use of the processor could damage it.
    Do somebody know how to use both the cores?

    This is a Mathematica problem. Contact their technical support. The Apple Discussions are limited to assistance with Apple products. We can't fix a problem with Mathematica software.
    Furthermore, there's no reason why the use of one core will damage your processor.

  • Intel I7 920 / only one core is working (?) Any idea?

    Hello all,
    I have a problem with my rendering. when I render with after, only one of the core's works (picture).

    adobe creative suit cs4
    my pc:
    intel core i7 920 2.67 GHz
    memory: 3 gb ddr3 (667MHz)
    card: Nvidia GeForce GTX 280 (1024 MBytes)
    Any idea what is wrong? ..Or recommended settings for better rendering (?)

    Dear Mylenium,
    First of all, thanks for your quick reply on my previews post.
    BUT, after reading a lot and watching the videos of Video2brain, I realized that everybody is talking about cs5. As I posted before... I have sc4. When I preview something in after ALL of my cores are working in order to render my preview. When I render my project things are different. Again I have the picture of 1 core rendering.
    Can I do something about that? Or, if I wanna use all of my cores I have to upgrade to cs5?
    Thank you in advanced

  • AME CC 2014 Rendering with only One Core

    This seems to have just begun recently (within the past month) where AME CC 2014 is only using 1 core (out of 12) to render video. No, this is not the CPU Parking issue - I have made the regedit tweaks and also changed my Power option to Performance, all with no difference in AME. Premiere Pro CC 2014 renders the same video just fine using all 12 cores, so it seems this problem lies not with Windows software, nor Premiere Pro, but just AME CC 2014. Was there a recent AME update that might have included this bug?
    Adobe, please look into this and resolve it ASAP. Not being able to queue up video renders is killing my productivity.

    I just installed Premiere Pro CC 2014 this week and had the same problem, my media encoding time tripled (3 times longer).
    The same sequence in Premiere Pro CC (Old Media Encoder ) still encoded at its normal fast speed.
    Only one of my eight cores was running during encoding in Premiere Pro CC 2014.
    After making the registry changes (below) all eight cores were running and Premiere Pro CC 2014 Encoder was back to normal speed.
    Read Below:
    I did a search and found this link below.
    Go to this link below and read.
    https://forums.adobe.com/thread/1506298
    After you have read the Adobe Forum link above, go to this link below.
    This registry change is for Windows 7, I'm not sure about Windows 8
    The registry link may be different but you can still look.
    Than call Adobe and have their tech go to this link below.
    Than have them suggest what to do.
    I did call Adobe back and told them it fixed my problem and they were appreciative and said they would pass it on to all their techs.
    http://ultimatecomputers.net/forum/viewtopic.php?f=7&t=3644
    Just a note,
    I was in touch with Adobe earlier this week with this same problem.
    I gave them control of my computer (from India) and after an hour the tech concluded it must be my video card causing the problem.
    I am using a Nvidia GTX 560Ti, which is not a certified card. I preformed the card hack.
    After getting off the phone with them I did some additional test and found that my old AME rendered my sequences with all eight cores.
    The new AME CC 2014 was only using one core.
    This registry change above keeps all the cores running.
    After I made the change all the cores were running during encoding and the speed was back to normal.
    Hope this helps,

  • 8 cores and only one is used fully?

    Why do I have 8 cores (16 are displayed in Activity Monitor) and only one of those 16 bars is really shooting up? Okay. Sometimes the others get something to do as well but, seriously... why do I have all this computing power and 1/16th of it is actually used? Why can one app cause the whole system to lag and become unresponsive?

    Yup, software applications have to catch up. And so does the OS's means for scheduling.
    Having a thread jump around between cores, try to attach the memory it needs, can and sometimes would make matters worse. We've seen that happen already. Core-thrashing, and the result can be increased heat and power, decreased performance. All from misuse of thread-locking, and not letting idle threads remain idle.
    The technical design of Intel Nehalem is complex but this review might help.
    The Cinebench benchmark is a ratio that measures how much faster the multiple threads are than running the benchmark with one thread; it's a true measure of how the threading scales when measured by rendering performance. InfoWorld: Multicore
    Barefeats has over a dozen benchmark reports just on Mac Pro 2009.

  • Dual Core yet only one is working win8.1

    Since a couple of days ago i've learn a trick which consisted in going to msconfig , Boot , Advanced settings and selecting 2 processos which would make my computer faster.
    I came to notice that my computer started getting slow , when i started "searching" for the cause i saw that my computer was working on 1 of the 2 cores that it has.
    Since then my win 8.1 has been working nearly always at 100% cpu usage , how can i put the dual cores back to usage?

    Hi,
    Please refer to the screenshot below to check your system boot configuration settings, make sure it's same with the picture.
    After that, please restart your computer to check if the problem resolved, if not, please feel free let me know.
