I wonder if VT-d support by the chipset is similar to which Intel chipsets support over clocking?

Only the 'Z' Intel chipsets officially support over clocking, but we now know how true that is given the non-Z OC feature and debacle that happened this year.

Finding VT-d support on boards that supposedly cannot support it seems to tell us that VT-d support is more dependent upon BIOS/UEFI support for VT-d, than the chipset itself.

If we check the manual of the H81 Pro BTC, we can see in the Chipset Configuration screen, there is an option to Enable or Disable VT-d:

Sorry about the H81 chipset warning, I should have looked at the board's manual, since that will tell us if VT-d is supported or not. I still think the CPU must support VT-d even if the board does, for it to be available. Note that Intel has VT-x support listed separately, so don't confuse the two.

I mainly wanted to warn about the H81 chipset apparently not supporting VT-d, since it is the chipset with the least amount of features in the 8 series, and with the most limitations on the extent of the features (only one DIMM per channel, four SATA ports total, only two SATA III, no RAID/IRST support, only two USB 3.0 ports, supports two monitors rather than three), and it is the cheapest of all the 8 series chipsets.

Alright, I'll give the H81 a go in a few weeks when it  arrives along with the rest of my components and get back to this thread about how VMWare reacts to it... I can live without it but the emulated NICs (if there is no passthrough) may hurt performance if I ever upgrade to FTTP. Thanks for your quick responses btw :)
