Hi out there .. looking for some information to this topic.

In detail it would be most important to know if the specific mainboard ( Fatality Z97M Killer ) supports the virtualization technologie VT-D

My I7 4770K does not and when the Mainboard also does not, then it would be stupid to go for a  VT-D capable Xeon CPU.

And if not, then it would be important to know witch  Skylake-mATX-Boards support VT-D.

Still no answer after 28 hours?

This question has to be pretty easy to answer from the techs

These are user forums not tech support Wink

While "ASRock_TSD" is a tech support representative the rest of us are just users like yourself, even us moderators. We can only answer questions we know the answer to and I prefer not to make guesses that could lead another forum member to waste time or money should I be wrong.

ASRock_TSD is on the forums on occasion but usually to address wide spread issues. If you want to get a response from Tech Support you can contact them directly by clicking the "Support" link at the top left of every forum window when scrolled to the top.

Good luck. 

If anyone else has an answer for you I am sure they will post it.

According to Intel, the Z97 chipset does not support VT-d. Scroll down on the page below to see that spec:

http://ark.intel.com/products/82012/Intel-DH82Z97-PCH

You then mention Skylake, which I assume you know is based on the Intel 100 series chipset, not the 9 series chipset.

For Skylake boards, VT-d is supported by the Z170, H170, H110, Q170, Q150, and B150. That is all the mainstream Skylake chipsets.

If you want to check this yourself, go to Intel's website and their "ARK Home", select a processor you are considering and display its specs. On the left there's an entry for "Compatible Products", which then lists all the chipsets that work with the processor. Click each chipset for it's information like in the link above.

Then again, does the board support it too? Choose a board, click on the manual link, skip to the Advanced, CPU Configuration UEFI/BIOS information, and look for a VT-d option.

This i got from the tech support via mail:



Hello,

 

if CPU support VT-D = The mainboard support it as well??u>

 

All socket 1150 CPU that support VT-D:

http://ark.intel.com/search/advanced?s=t&SocketsSupported=FCLGA1150&VTD=true

 

All socket 1151 CPU with VT-D support:

http://ark.intel.com/search/advanced?s=t&SocketsSupported=FCLGA1151&VTD=true

 

Best regards,

What they are saying is that if the CPU supports it then so does the motherboard. If a CPU without support is installed in a motherboard then the option disappears from the UEFI (would have been grayed out in the days of BIOS). As you can see on the links they provided you there is a "VT-D = yes" filter applied.

I find it very odd that your i7 4770K seems to be the only i7 not listed with support. It may be an error in the data on the ARK site, you could contact intel and ask them. Given the 4770 (non K) is in fact listed it stands to reason that the 4770k should be too.

After a little bit of research it seems like this:

initial Haswell "k" CPUs dont support vt-d 

4770 = vt-d - 4770k = no vt-d

Haswell Refresh "k" CPUs suppert vt-d

4790 = vt-d - 4790k = vt-d


This is alos for the i5 series ... so it seems my CPU just dont support vt-d by itself

That may well be the case, it is possible they disabled VT-D on the first series of Haswell K CPUs due to the overclocking features but then left it in place on the refresh or Devils Canyon CPUs, likely because the feature proved stable even with an overclock in place. 

In that case a Xeon or even an i7 4790k should give you VT-D support. I wouldn't bother upgrading from Haswell to Skylake as the performance gains are negligible and as with most new architectures there still seem to be a fair number of bugs in Skylake systems.

If tech support says it is dependent on the CPU then that means that all Haswell based boards must have support for it.
