    Default Problem with Gigabyte GPU

    Couple of months ago i bought Gigabyte 4870x2 (GV-R487X2-2GH-B) graphic card
    and i was very happy with it. Untill recently i decided to upgrade my computer and got new mobo and memory upgrade.
    Since then every time i start any 3D application, any game or 3D benchmark my video card starts making this LOUD buzzing sound.
    The buzzing sound stops at the very moment i close the 3D application. I can play games normally but the buzzing sound is really getting to me.
    The Buzzing sound varies from game to game, in some games the buzzing sound is very loud and some games it's just quieter but still noticeable.

    I've updated my BIOS, i have the newest Catalyst drivers and i have checked that the sound doesn't come from my fans.

    Before the upgrade i had this kind of setup:
    Asus P5k-E Wifi
    4gb Kingston 800mhz ValueRam

    And now i have
    Asus Rampage Formula
    8gb Kingston HyperX 1066mhz

    I have Core 2 Q9450 and Corsair 650W. My prosessor is at stock but i had to overclock the memory to get it to work. I haven't done any overclocking for the GPU.

    The only thing i can come up with is that my PSU isn't feeding enough my precious GPU and that's why it gets all cranky on me.

    What do you guys think?

    Sounds like coil whine to me. A component on the power regulation section of the card is vibrating at a very high frequency and causing the sound. It may also be the fan, to test this you can safelt mannually stop the fan carefully with your finger while running a 3D app. if the noise stops, it's the fan. If it doesn't it'd the coils.

    Loads of 8800 series cards had this exact problem, and I recently returned a BFG PSU because of it. It can be solved with either a replacement card, or coading the offending component with caulk (a white silicone like gunk that dries to the same consistency as glue from a hot glue gun, it stops the component vibrating). I've fixed a couple of old PSU's in this way, but I have basic understanding of electronics (A-level) so it wasn't to daunting.

    I'd recommend you RMA the card, rather than fix it yourself. It must be noted that RMA's have been refused by some companies because of this issue. It's annoying, but the sound isn't an indication of a terminal problem. The card is still 100% electrically safe.
