    VT-d support with Intel DX79SR MB and Intel i7-3960X CPU

    John

      Hi,

       

      I have an Intel DX79SR motherboard which according to Intel supports 'Intel
      VT with Directed I/O' as per for the following Intel page: http://www.intel.com/support/motherboards/desktop/sb/CS-030922.htm

       

      I also have an Intel Core i7-3960X Extreme Edition CPU which also supports VT-d as per the spec on the Intel website pages: http://ark.intel.com/products/63696/Intel-Core-i7-3960X-Processor-Extreme-Edition-15M-Cache-up-to-3_90-GHz and here: http://ark.intel.com/search/advanced?VTD=true&MarketSegment=DT

       

      The X79 Express Chipset is supposedly VT-d supported too: http://ark.intel.com/products/64015/Intel-BD82X79-PCH?q=x79

       

      HOWEVER VMware ESXi 5.1.0, 799733 displays the following in the advanced settings (where you set-up VT-d passthrough etc): "Host does not support passthrough configuration".

       

      I realise the this MB is not on the VMware HCL, however I'm both confused and disappointed as to why VT-d doesn't show as supported.

       

      Can anyone comment as to why VMware displays this message, when the Intel website information clearly states that this motherboard , CPU, and
      Chipset support VT-d?

       

      I have flashed the BIOS to the latest version (0553) and the virtualization support is enabled in the security tab of the BIOS. However it does NOT mentioned "VT-d" or "Directed I/O" in the BIOS, and from what I've seen elsewhere, true VT-d enabled boards display VT-d or Directed I/O in the BIOS...

       

      Thanks
