VT-d hardware support on chipset Z87 (DH82Z87)

VT-d hardware support on chipset Z87 (DH82Z87)

There seem to be some inconsistency on ARK product reference site:

This document Compatibility with Intel® Virtualization Technology (Intel® VT) (http://www.intel.com/support/motherboards/desktop/sb/CS-030922.htm) specifies that chipset Z87 (DH82Z87) supports VT-d:
   The following Intel® Desktop Boards support Intel VT with Directed I/O:
   ChipsetDesktop Board H87, Q87, Z87 - DH87MC, DH87RL, DQ87PG, DZ87KLT-75K

and the chipset product page here http://ark.intel.com/products/75013/Intel-DH82Z87-PCH says:
   "Intel® Virtualization Technology for Directed I/O (VT-d) ‡ No".

Please confirm if this chipset supports this virtualization feature.

Thanks,
Biv

Hello,

I am also confused by your information.

If I read http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/8... I can find no restrictions regarding VT-d.

Chapter 1.2.1 Capability Overview, page 52 of 992:

Whenever there are restrictions you can read: See Section 1.3 for details on SKU feature availability. In the section Intel® Virtualization Technology for Directed I/O (Intel® VT-d) you can not find this restrictive hint.

If you go to chapter 1.3 Intel® 8 Series / 220 Series Chipset Family SKU Definition, page 54 of 992 you will not find a restriction for Q87, Q85, B85, Z87 or H87 regarding Intel® Virtualization Technology for Directed I/O (Intel® VT-d).

Chapter 5, Functional Description, page 302 of 992:

5.29 Intel® Virtualization Technology (Intel® VT): There are no restrictions described.
5.29.1 Intel® Virtualization Technology (Intel® VT) for Directed I/O (Intel® VT-d) Objectives: There are no restrictions described.

If I look at http://ark.intel.com/compare/75013,75007,75004 (Compare: Intel® DH82Z87 PCH, Intel® DH82Q87 PCH, Intel® DH82H87 PCH) I get the following result:

Intel® Virtualization Technology for Directed I/O (VT-d) ‡

Intel® DH82Z87 PCH: No
Intel® DH82Q87 PCH: Yes
Intel® DH82H87 PCH: No

If I look at http://www.servethehome.com/intel-z87-q87-q85-h87-b85-pch-differences-ex... I get the following information:

Intel® Virtualization Technology for Directed I/O (VT-d) ‡

Intel® DH82Z87 PCH: No
Intel® DH82Q87 PCH: Yes
Intel® DH82H87 PCH: No

If I look at https://en.wikipedia.org/wiki/Intel_Series_8_chipset I get the following information:

Intel® Virtualization Technology for Directed I/O (VT-d) ‡

Intel® DH82Z87 PCH: No
Intel® DH82Q87 PCH: Yes
Intel® DH82H87 PCH: No

Beside selecting the right motherboard, the combination of processor and chipset is also important so here are a couple of comparisons in ARK: 

The first shows all the processors listed as compatible with the Intel(R) DH82Z87 PCH, so you can see which do and which don’t have vPro: http://ark.intel.com/compare/75125,75124,75123,75122,75121,75050,75049,75048,75047,75045,75044,75043,75040,75038,75037,75036

And this compare is the list of only those from that list that are both compatible with Intel(R) DH82Z87 PCH and also have Intel(R) vPro(TM) technology (basically just removed the non-vPro): http://ark.intel.com/compare/75125,75124,75123,75122,75121,75050,75049,75047,75045,75044,75043

Dear Thai!

 As I see the original question was related to Vt-d and not for VPRO.

I would really appreciate a clear answer for this question; whether the Z87 chipset (and motherboar built with it) supports the Vt-d virtualization function or not.

Thanks for your help,

Hi Szabolcs,

The key is to get the correct combination of chipset, processor, and mortherboard for the system to support the virtualization.  The list of processors provided above were to help you selecting the correct processor to work with the Intel® DH82Z87 PCH.  Besides the hardware, the software that will need to support virtualization as well.  In this case, I would refer you back to the software and system vendor to help you selecting the right combination. Here is one location to choose a mortherboard: http://www.intel.com/content/www/us/en/motherboards/desktop-motherboards/motherboards.html

Hope this helps,
