    Default VT-d support on Z77 motherboard

    The GA-Z77-D3H motherboard supports VT-d according to its manual.
    But according to Intel's spec sheet:
    http://ark.intel.com/products/64024/Intel-BD82Z77-PCH
    the Intel Z77 chipset doesn't support it.
    Does the motherboard really support it?

    It is my understanding that the unlocked K processors don't support it, the locked ones do. I didn't think it was a function of the chipset. Check Intel ARK for CPU specs, K series don't support VT-d.

    I'm well aware that the K processors don't support VT-d. My understanding is that cpu, chipset and BIOS need to support VT-d to be able to use it.

    So the question remains:
    Does GA-Z77-D3H fully support VT-d (when used with a compatible processor) even though Intel claims the Z77 chipset doesn't support it?
    Or does it only partially support VT-d, only passing a subset of the 50 tests in the VT-d validation suite?

    My board (Z77X-UP5 TH) supports VT-d in the BIOS under chipset option.

    What is this VT-d validation suite? I'd assume it either supports VT-d or doesn't. I know the Q series chipsets are suppose to all have VT-d support.

    If you can point me to this validation software I can check my board.

    Don't ya just hate it when you hold down the the shift key for one too many key presses and end up typing out an * instead of an 8 ?

    #1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.
    ____If you are overclocking, underclocking, or undervolting any parts, informing us of this and their values would prove beneficial in helping you.

    #3 - Please use the eXtreme Outer Vision Power Supply Calculator found HERE to determine if it might be your PSU at issue.
    ____Consider your PSU to be the foundation from which all else is built upon. Anything built upon a weak foundation is poorly built.

    I have only seen mentions of it, never a download link. Here it is discussed that it failed Asus Z77 boards and Asus therefore don't include VT-d support:
    ASUSTeK Computer Inc.-Forum- Z77 VT-d

    I was hoping Gigabyte staff would reply here, but doesn't seem to happen. What is the best way to ask them this question directly?

    You can call Gigabyte in the US, don't know if there is a Euro number but I would think so. Or you can put in a support ticket online and ask them whatever.
    It's extremely unlikely anyone from Gigabyte will reply here in the forum.
