    Default Is this a design flaw of GA-X58A-UD3R?

    System Configuration

    -------------------------------------------------------------------------------
    Model Name : GA-X58A-UD3R(rev. 1.0) (Purchased on 10 May 2010)
    -------------------------------------------------------------------------------
    M/B Rev : 1.0
    BIOS Ver : F5
    -------------------------------------------------------------------------------
    VGA Brand : XFX Model : 8600GT
    CPU Brand : Intel Model : Core i7 920 Speed : 2.66GHz
    Operation System : Win XP SP : 3
    Memory Brand : GSkill (ECO series) Type : DDR3
    Memory Size : 4GB Speed : 1600MHz (but running at 1066MHz at the moment)
    Power Supply : 600 W
    --------------------------------------------------------------------------------


    Problem Statement
    When Google Chrome is open, I can hear a "high-pitch high-frequency" (HPHF) noise from the computer, which is not very loud but audible and very annoying especially at midnight when the environment is quiet. The HPHF noise is not from speaker because at the moment no speaker is connected to the computer. After a careful investigation using a "straw", I think the noise is from somewhere around the CPU socket (i.e. under the CPU heat sink fan, I'm using Titan Fenrir v2). If we look at the motherboard layout, power regulation circuitries are very close to the CPU socket.

    My problem is similar to that described here. After disabling the C1E in the BIOS or through the Setting tab of Real Temp, the HPHF noise has gone. However, the temperature of the CPU at idle is approximately 5 deg Celsius higher now!

    My question:
    [1] Is my newly bought Gigabyte GA-X58A-UD3R faulty? RMA?
    [2] Is it a design flaw (e.g. poor VRM at low load) of the Gigabyte GA-X58A-UD3R and therefore it does not support well the C1E feature of Intel Core i7, which is one of the important features of the processor?

    I found out that the HPHF noise is significant if the CPU voltage (monitored by EasyTune6) falls within (0.928~1.200V). When the CPU voltage is maintained at 0.928V, i.e. at very light load, and when it reaches 1.200V or above, the HPHF noise's gone. Can I say that the VRM of the Gigabyte GA-X58A-UD3R does not work well within 0.928~1.200V? I guess the HPHF noise is emitted by the inductors used in the VRM.

    Kindly advise what I should do next.

    its intel power saving feature,go in bios under advanced cpu features and disable c1e,if you have windows 7 installed look in start/control panel/system and security/power options and make sure you choose balanced power saving option,it will do same job as c1e in the bios but without the noise,if your still getting mb noise try closing easytune aswell but its most likely c1e,my board makes the noise also

    xp doesnt have power saving profiles so i cant think of anything else you could try

    its the noise of the chokes when they ristrict the voltage to your cpu that you can hear,try using cpu voltage normal setting,it will help reduce idle temps if you disable c1e and also set qpi/vtt to normal voltage setting/only for stock clocks though

    Thanks for your reply. Can I say that my motherboard is faulty (due to the noise made by the chokes)? Or, is it the design flaw of the GA-X58A-UD3R and thus even after I send for RMA the new unit I get will have the similar problem as well? Thanks.

    I wish Gigabyte engineer to give their opinions. By comparing the m/board layouts of GA-X58A-UD3R version 1.0 and 2.0, one of the major differences which we can observe is the design of the m/board VRM. It looks to me that the VRM of version 2.0 has higher number of phase than that of version 1.0. With improved design of the VRM, do you think the HPHF noise issue can be eliminated? Thanks.

    i dont know,you might rma and they send you a board that does it more,thats if they accept it for faulty/noisey chokes.i think all boards make this noise, what brand psu do you have as this may cause it, also your gpu can cause the noise,best option imo is to upgrade to windows 7,i have both win7 and xp and i can say that the noise stops in win7 if u use balanced profile and disable c1e in bios-it lowers cpu vcore when idle also just like c1e but with no noise,when i use xp i have to enable c1e in bios because my idle temps are too high, use the latest lan and chipset and audio drivers as this helps to lessen the noise

    I wish I could move to Windows 7 but due to some driver issues of few software I've to stick with Windows XP at the moment. The HPHF noise is very annoying and it will eventually drive me crazy especially at the middle of the night when surrounding is quiet. By the way, my power supply is OCZ 600W.

    If you refer to my first post, this HPHF noise happens only when the CPU voltage falls within 0.928~1.200V. If the CPU voltage is constantly maintained at 0.928V, then I do not hear the noise. Thus I really hope that Gigabyte engineer will explain why this happens only within 0.928~1.200V, but not at 0.928V since at this voltage the VRM also restricts the voltage to the CPU.

    it happens when voltage is low because the chokes are throttling the cpu voltage at that point,when the load on the cpu increases it frees up the voltage to 1.2v and you dont hear the noise because the chokes dont need to throttle the cpu v,you wont hear the noise when cpu is under a certain amount of load only when its idling, ocz psu's are problematic with gigabyte boards alot just wont power up some do,if you try another psu theres a chance it might stop the noise but i cant say 100%

    Kindly advise what I should do next.

    what you say suggests that an inductor in the on board voltage regulators may be squeaking. This may happen because of large current changes in the inductor and a core that is not firmly attached to the coil.

    Is it possible that you may control or affect the squealing of the inductor by pushing it with an insulated tool such as a chopstick?

    If you are able to demonstrate this, you know the component causing the acoustic problem.

    Then you may decide to RMA the motherboard, or try to fix it yourself. You may use some potting material, RTV, or similar, up to the point that you change the inductor alltogether, loosing your warranty.

    I would investigate first.

    Good luck, Jure Z.

    I appreciate very much for your effort to explain it. If you read carefully my post, there is NO such noise at very low CPU voltage (i.e. 0.928V, which I think is the minumum voltage the motherboard can give), which at this point the chokes, I believe, should work "harder" to throttle the CPU voltage than any other voltage higher than 0.928V. When the CPU voltage increases, e.g. 0.940 or 0.960 (or any value between 0.928 and 1.200), then the noise appears. I'm not sure if it's due PSU. If you read this thread, you will find out almost everyone who bought this board, when used with different PSUs, has the same problem.

    Well, maybe it was not clear enough, but the different load situations (voltage, current) determine the way and conditions the regulators actually work (even the number of sections or phases active). I may very well be that this is the case.

    So, it maybe a bad component or a bad design altogether. (a design which causes undesired effects at some load).

    good luck, Jure Z.
