Intel(R) Pentium(R) CPU G620 @ 2.60GHz

Hello guys.
Im having a some problems with my CPU.
Since my english is not fluent and im not really a PC Engineer ill try to explain the problem best i can.
Im using MSI Control Center and i think i have some issues with my motherboard / processor.
Frequencies of CPU are very oscilating, they ussualy work at x16.0 but is that good? I mean i see they can work at up to x27.0 so should i maybe set them at x26.0?
If i should do that, can u tell me how? I dont want to hurt my system by doing something that i dont really understand.
Also ive noticed that my iGPU is always at 0 MHz. I dont know what is iGPU exactly but i think this cant be good.
If anyone can tell me how can i make my CPU steady in few simple steps and how to enable iGPU please.
I would be very greatefull to you!
Thanks in advance.

What motherboard do you have? What other parts are in your system? So far all you tell us is what CPU you have and nothing else.  Do you have a separate graphics card or are you using IGPU (Integrated Graphics Processing Unit)? CPU speed will vary depending on load, light load slower speed, heavy load higher speed. If you have a discrete video card then IGPU will be zero.
 Since that is a LGA1156 CPU this is posted in the wrong section of the forum, it should be in Intel iX section.
Ive also forgot to mention that im getting Black Screen Bug while playing some games, League of Legends exactly. And i think its somehow related to my CPU, but im not sure.
After i start the game, whole screen goes black and im unable to do anything about it. I cant even ALT+TAB it so i ca see my CPU usage..completely cut off from my PC while this is hapening.
It does hapen always, each time i start the game and it lasts for about 1-2 minutes. Screen is blinking in black like its trying to refresh itself.
Here is complete DxDiag of my PC.

  • Creative Cloud Requirement: Does Intel Pentium Dual CPU E2200 @ 2.2GHZ 2.20GHZ work?

    Creative Cloud requirements ask for Intel® Pentium® 4 or AMD Athlon® 64 processor (2 GHz or faster). I have an Intel Pentium Dual CPU E2200 @ 2.2GHZ 2.20GHZ, which supposedly is better than a Pentium 4. Can I install the Creative Cloud apps on my computer as long as I have Windows 7 64 bit version?

    By the way, I called support since no-one was answering this. And they said "yes, the requirements are a minimum. If you have something better (in this case I do) it will be fine".

  • Will the new Fire Fox run so well as the actua in my pc? I have an Intel Pentium 4 CPU 2.40 GHz 736 MB RAM and Windows XP Version 2002 Service Pack 2 and Fire Fox 3.6.24 or it will take my pc more ressources than currently?

    Pay attention to what rkaufmann87 is saying, because I agree.
    Chrome is very resource intensive.
    It is possible you are running other memory intensive apps.
    You have a lot of 3rd party additions loaded at boot time.  Do you really need all of them?  Even after you get rid of MacCleaner (as suggested by rkaufmann87).
    Do you really need the seagate and WD drive software?  The Mac is fairly good at accessing disks without 3rd party intervention.
    Any of the 3rd party additions listed by EtreCheck that you do not need, you should consider uninstalling.
    That fact that you have
        171.19 GB    Page-ins
    in just about 4 days, says you have about 0.5megabytes per second.  That is a huge load on your disk drive.
    Either cut back on the RAM intensive apps, or get more RAM.  At least 8GB, but if your Mac supports it, 16GB.  Crucial.com and MacSales.com (OWC) are well respected by the long term forum contributes.

  • Can I run Lightroom on a PC with an Intel Core 2 Duo CPU?

    The specs for Lightroom state that you need a Pentium 4 processor.  My PC has an Intel Core 2 Duo CPU @ 2.2Ghz.  Is this sufficient?
    Thanks.

    Hi vc10,
    You can install Lightroom on Core 2  Duo Processor.
    P4 processor is the minimum system requirement for it.

    Fixing a Mavericks Installation Problem
    How to manage a failed OS X Mavericks installation | MacFixIt - CNET Reviews.
    Try these in order:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
         after the chime press and hold down the OPTION key until the boot manager screen appears.
         Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

    Hi:
    I am looking at the BIOS setup guide for your PC series and it shows there is a VT setting under the device configuration menu for "select models." See Chapter 3 page 6.
    http://h10032.www1.hp.com/ctg/Manual/c01662442.pdf
    Here are the specs on the T6500 processor. It does not support VT, which is why the VT setting cannot be enabled.

  • Intel Core2 Quad Q9550 CPU, 2.83GHz

    Hi!
    I dream of buying the new processor called Intel Core2 Quad Q9550 CPU, 2.83GHz.
    Is it to suit my motherboard - Marketing Name: P35 Neo2-FR/FIR; MSI Model: MS-7345?
    Intel Core2 Quad Q9550 CPU, 2.83GHz has 45nm. My motherboard can receive 45nm or 65nm only?
    If so, do I need to upgrade the BIOS?
    If there is no upgrade from the BIOS. It means that I can only put into Intel Core2 Quad Q9550 CPU, 2.83GHz to the motherboard.
    Regards Lillemester :-)

    Yes it can, check CPU Support page:

    all other 865 chipsets support intel celleron cpus but msi mobos not ! why? or is there any way that i can run mobo with celleron 1.7 cpu?

    yes, we have tried. yesterday i bought a new mobo for my friend. he has celleron 1.7, when we start the system it does nothing also the d-bracket colors are

    OO
    O:red that means "the d-led will hang here if the processor is damaged or not installed properly! "
    the same procesor is workings with no problem on his old board!
    is there any solution that you can suggest? as i sad all other 865 chipsets  support celleron cpus! :(

  • Intel CPUID says my CPU is overclocked?

    Hi there
    I have the MSI 875P m/b and the Intel 2.40C Ghz CPU.  My motherboard is not overclocked (at least not as far as I know, the default settings are enabled), but I have just launched the Intel Processor ID Utility v5.6 and I get the following:
    Reported Frequency: 2.43Ghz / System Bus: 811Mhz
    Expected Frequency: 2.40Ghz / System Bus: 800Mhz
    Underneath this there is a yellow exclamation mark and it says "overclocked" and also has an "advisory".
    I know that the speeds are not much higher than the expected frequncies but for the time being and because the parts are new, I would like my system and especially the processor to run at the normal speed.  Can someone tell me exactly what are the default settings that I should have so that the processor and system bus run at their "expected frequencies", and also what I need to adjust and where in the BIOS are these settings are please?
    If you would like to know more before you advise me, please ask me what settings you would like me to quote.
    BTW:  CPUID v1.19b from CPUID.COM also reports the same frequencies.
    Regards      

    Hi to all
    DOS:  I am quite prepared to believe your comment:
    "You've been around here long enough to know that all of the 865 and 875 motherboards are slightly overclocked at the standard "Slow" performance", and I guess that this "must" be the case here because my PAT is 100% set to the default setting of "SLOW" and I do not have "High Performance Defaults" enabled and after enabling "BIOS Setup default settings" and rebooting, the CPUID frequencies were still the same as I first reported:
    Reported Frequency: 2.43Ghz / System Bus: 811Mhz
    Expected Frequency: 2.40Ghz / System Bus: 800Mhz
    So, with "Performance Mode" now in the BIOS since BIOS v1.7 and left the default of "SLOW", all Intel CPU's must be slightly overclocked on this and similar boards?
    REILLY875:  Thanks for your response and yes your right, I am not that bothered at the difference in FSB of 811Mhz, as it's hardly worth thinking about but I was just wondering why when I had all the defaults chosen, my FSB and CPU were, according to INTEL CPUID, overclocked; especially as you mentioned your friends Intel 875-PBZ was also showing overclocked.
    Assaf:  As I stated above, my BIOS settings are default, so I guess that my FSB/CPU frequencies must be normal for this board and, apparently the 875 Intel board.
    So, as I don't want to play around with the FSB clock settings, I guess I'll just leave well alone.
    Many thanks for all of your comments.
    Regards

    Depemding on where you are from Crucial has four international web locations.

    I have installed 64 bit distros on here before without any issues.
    I know I could just use the i686 core disc but this would not allow me to run my 64 bit xp virtually within Arch.
    The 64 bit Arch image allows me to get to the splash screen but then fails when it gets to the udev part of the boot process...
    Google turns up no related results.
    Any help would be appreciated.
    Thanks,

    I agree with the above post, you have not provided enough information. But the fact that the boot process fails might indicate an issue with KMS. Do you have an ATI or Intel VGA? Furthermore, "...but then fails..." can mean anything, what exactly happens? Does you laptop explode? Does your screen go black? Explain further...

  • Installation problem on W2k computers with Pentium 4 CPU

    The installation of Discoverer 4.1.37 stops before it is finished and says - Installation successful!
    Every unnecessary service is stopped prior to installation,
    The almost installed application can't start and generates and application error in Windows when I try.
    This event only occurs on computers with an Intel Pentium 4 processors....!
    Anyone else? Patch for this? Workaround?

    You can look at the intel support site. They have the explanation and the solution for that problem. The problm i's related to a file named sys*.dll. They tel you exactly what file it's the poblem and How you can obtain a new version of that file.
    Hope this helps

  • [SOLVED] Intel i7-3920XM Laptop CPU Linux Kernel Support

    Recently, I purchased a laptop with an Intel i7-3920XM CPU, with the intention of utilizing it for scientific computing (I've become strongly interested in machine learning and artificial neural networks).  Supposedly, the CPU has a variable clock speed of 2.90 -- 3.80 GHz, which would be great, but my kernel has throttled it to 1200MHz.  I've tried both the cpufreq performance and userspace kernel modules (configured for performance), but the laptop stubbornly refuses to increase the clockspeed more than 1200MHz; I gave up on cpufreq and have uninstalled it.  I've read some accounts that it is possible that the Linux kernel may not support my CPU yet --- does anybody know if that is the case?  If it is not, can anybody point me to some literature describing how to un-throttle my CPU?

    CPU frequency scaling is enabled by default, 1200MHz is fine for your processor as it's lowest frequency I have the 3960x and it's lowest frequency is 1200MHz as well.
    You should just leave things as they are, if you can actually feel sluggish performance ( I don't with 6 cores @ 1200MHz) you can try this:-  https://wiki.archlinux.org/index.php/Cp … erformance
    Which will liven things up a bit at the cost of more battery juice.
    EDIT/ compile something and whilst compiling
    cat /proc/cpuinfo | grep MHz
    to see what's reported at full load, but be aware it still may not report correctly due to turbo.

    I would agree with you if that was what the argument was about. I said the same thing about i7z as you just did, which is why i suggested it. as I understand it. your telling him 1.2 Ghz is an acceptable min and i would agree.How i am interperting his thread is 2.90 Ghz is his base. 3.80 Ghz is his max turbo. His CPU under 100 % load will not rise above 1.2 Ghz despite his stock clock is actually 2.90 Ghz. I can honestly say that this is the more likely story because my i7 did the same thing. on battery the max it would clock up to while runing /dev/urandom > /dev/null was 1.2 Ghz, while on Ac it would even turbo correctly. by unloading the module.  my proccessor would clock as expected 800 mhz min 3.4 max turbo. and if you look he even used the performance governor to try to increase the clock
    Ya, really the OP did not tell us 'how' he was reading his CPU speed....

    runny6play: If deltaecho is also seeing these same slow speeds in i7z then both you and he should look into your BIOS settings. For sure this would be a BIOS setting on a ThinkPad. "If on battery....slow... if on AC...fast".
    Yes, it is the Linux Kernel that is no "Reporting" the correct speed. This is a known bug. However, there is nothing wrong with your CPU. It is running at High Speed.. Like this is the read out from my Kernel at idle...
    [user@archtop:~]% sudo cat /proc/cpuinfo | grep MHz
    [sudo] password for user:
    cpu MHz : 1200.000
    cpu MHz : 1200.000
    cpu MHz : 2901.000
    cpu MHz : 1200.000
    The BEST way to test your CPU is, again i7z then compile some code... Like change the MAKEFLAGS="-j4" to -j1 for 1 thread, -j2 for 2 threads.... and so on. Compiling software will push your CPU all the way up.
    When testing like this, i7z will show on 1 thread my CPU runs at 3.6GHz, on all 4 threads it runs at 3.4GHz, as it should. However, /proc/cpuinfo will only say wacky stuff like cpu MHz: 1200.000 cpu MHz: 2901.000

  • G580 Intel I3-2348M, what cpu upgrades can be done?

     I'm writing to you, because I have a G580 /20150/ laptop with an i3-2348M CPU and I want to upgrade it to a higher level CPU ,i5/i7 if it possible. I know that my motherboard has a 988b socket, so I want to ask you, please tell me the list of those CPU-s , which are compatibile with my configuration. I'm attaching a photo of my laptop's specs. I1m looking forward to your answers!  

    hi simond930203,
    Welcome to Lenovo Community Forums!
    Thisis the Hardware Maintenance Manual of that system

    Check this manual at pg. 101 for compatible CPU that would work on the system
    Also use that manual as your reference on replacing the part.
    Make sure to check the Chipset model of your system and check that chipset model with Intel website and confirm that the CPU you want is listed there.
