It's a non K and it's a lucky one, it can almost OC to an average 4770k. But one of the reasons I have the non-k is vt-d. I'm sure z97 is the same and you guys are just speculating unaware of the already built haswell-r rigs because most don't bother testing virtualization on an 'enthusiast gaming' processor.
Just to let know, I have a Gigabyte 77x-D3H that supports VT-d just fine. I have been running it with a i7 3770.
I was running Arch Linux with Xen 4.3.1 as dom0, and Win 8.1 Pro as one of the domU's. I used VT-d to pass through my Radeon 290 and Creative X-Fi, as well as a SATA controller and a couple of USB ports. It worked really well and I could play games like BF4 and Arma 3 in native performance.
Apparently this board have VT-d too. It's gonna be my next one to try together with 4790K :)
But you've got a locked ivy i7. I'll be interested in results with the unlocked haswell refresh, though.
Yup, I mostly use Gigabyte boards too, they're pretty much worry free in terms of supported features and BIOS updates and support.
Cool that you got it working. Since you're on Arch, and therefore on bleeding edge kernel, you don't have to bind your X-Fi to the guest, you can actually use the X-Fi for both the host and the guest at the same time, because you can now route USB devices over TCP. So you can make the X-Fi available to the guest as a network device. It works as it should (X-Fi USB 5.1 pro confirmed on my system).
The cool thing is that this also goes for USB storage, which is nice, because not only can you natively turn USB storage into network storage, you can also use maximum security on all different levels for just plain old local USB storage, and you can make linux filesystem volumes on USB storage easily available to Windows.
Yeah, my meaning was to share info on a mobo that has support for VT-d and works well with it. There is not a lot info on that easy to come by. I will make a post here on results with GIGABYTE GA-Z97X-Gaming G1 WIFI-BK with i7 4970K when I get it.
Thanks for sharing, that is very cool! I got the X-Fi Titanium PCI-e though. But I am sure going to check out that feature with some other device.
i know its an old post; but nah i have a Asus Rog z87 impact board and it has support for VT-D, however you have to have the non k version of the I7 4770..
Is this board specific? The i7-4770K doesn't have VT-D, but the i7-4790K does support it.
Asus allways claimed support for DC cpu´s on their Z87 board, with a bios update. Since a 4790K does support vt-d, it could be that with a new bios update this feuture gets enabled. But it could also be, that vt-d has allways been their on ROG boards, and / or Asus MS / TuF boards.
I need to research that some day lol. Because there where allot of Z87 boards that did not have vt-d support. there where specific Q87 board for that.
Basicly if you have a Z87 board right now, just check the Bios feutures in the manual. Or if you look for a specific Z87 board, download the manual and check it.
ok so this should clear this up a bit:
Intel® Desktop Boards require the following components to support Intel® VT or Intel® VT-d:
- Intel® Processor that supports Intel VT
- BIOS with Intel VT or VT-d support (found on the Security menu in BIOS setup).
So it depends on CPU and also on Bios...
here is a list of CPU:http://en.wikipedia.org/wiki/List_of_IOMMU-supporting_hardware
Sorry, that is not true. I have VT-D enabled on my Sabertooth Z97 Mark 1 with the 4790k. Also the 8350 is not "better" for visualization. I had the 8350 prior to my 4790k I am able to do much higher density workloads. The 8350 is still a great value for this type of workload though don't get me wrong.
