Z97 chipset, i7-4790k CPU, and vt-d/(Intel Virt Tech) MoBos?
« on: August 09, 2014, 06:04:27 am »
Folks,

If you could give this a serious read. I'm in the process of planning and analysis... Have a old comp for home and games (comming up on 6 years). I really need an upgrade. Of course, I've kind of gone down the rabbit hole.

I'd like some good idea what is what.

I've fallen in love with the GA-Z97X-Gaming G1 (yeah, dont really need the wifi black, however the integrated surrounding cpu water block is a great feature).

However, it has kind of shook me up the various developments in not having to dual-boot, keeping my tech skills fresh and the possibility to have room to overclock, upgrade and passthru devices things would be fantastic.

So, looking at the specs of the Devil's Canyon/Haswell refresh.

The i7-4790k

http://ark.intel.com/products/80807/Intel-Core-i7-4790K-Processor-8M-Cache-up-to-4_40-GHz

has the ability to be overclocked... and/or left at default and has VT-d tech.

so reading all the head spinning info about what is compatible versus not-compatible.

I see here on the Gigabyte site.


http://www.gigabyte.com/products/product-page.aspx?pid=4963#ov

the manual for the GA-Z97X-Gaming G1 (p.s. also compared this mother board versus the EVGA Classified and this board rocks)

In the manual for the GA-Z97X


http://download.gigabyte.us/FileList/Manual/mb_manual_ga-z97x-gaming-g1_e.pdf


pg 53-55 section 2-5 BIOS Features
53 screenshot of VT-D tech option
55 Intel Virtualization Technology.(Note)
Enables or disables Intel® Virtualization Technology. Virtualization enhanced by Intel® Virtualization
Technology will allow a platform to run multiple operating systems and applications in independent partitions.
With virtualization, one computer system can function as multiple virtual systems.
(Default: Enabled)


tl;dr

So folks please tell me, is VT-D really included on the GA-Z97X-Gaming G1? is this just filler for the manual?  ???

Is VT-D(a.k.a. Intel Virt Tech) included on any of the Gigabyte Z97 boards?


Sincerely,
BattleBrother


p.s. Damn PCPartPicker is worse then cookieclicker.

Well yes but it also depends on the CPU you use. I have that motherboard and a 4790k and have vt-d enabled and works well.

@autotech how did things work out? Did you get the card and did it have VT-d?

This card got a marvell controller and they don't follow the pci standard which cause problem for IOMMUs. The Linux kernel bugzilla got a description of the problem: https://bugzilla.kernel.org/show_bug.cgi?id=42679

Kernel 3.16 contain the commit cc346a4714a59d08c118e8f33fd86692d3563133 which tries to work around the problem but I don't know if it works as well. Xen and other solutions also needs to implement some kind of workaround if you plan to use them.
