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

[leao]

Hi,
Why Gigabyte's motherboards doesn't have Intel® Virtualization Technology for Directed I/O (VT-d)?  

I try configure my bios and nothing... I try to find a new motherboards and nothing...  

What's happening?

Best regards,

The different types of VT that are supported depends on what CPU you have.

Hi,
My CPU is q9400 and have VT-d, but in the bios doesn't show any option to active it.
the xenclient setup show me VTx is enabled but VT-d is disabled...

I looked in the manual for my board and also on new motherboard on site and the bios has no option to enable VT-d. My friend has an HP computer and have the option. My computer at work is Dell and also have the option. My cousin has an Intel  motherboard also has that option.

This is a very strange...

Please take a look on your bios and verify this options.

thanks,

Did you try the advanced options by pressing CTRL and F1 when you are in the BIOS?

If you still can't find it I would open a question with GGTS.

Hi,
Yes, I try CRTL and F1, but still show only "Virtualization technology" option, not Vt-d option

My motherboard is:
G31M-ES2L Bios ver F10

Sorry Leao I can't help any more I suggest that you ask GGTS.

I've opened a tickect, but the first answer was to enable virtualization is just for the option in the bios about virtualization technology.
I explained the Vt-d option is an extra, but I'm still waiting for the answer.

Thank you for your help, so when I have the resolution, I will  put here in the forum, but is very strange, all motherboard manual I see on gigabyte website, doesn't have any indication or information about Vt-d...

Thanks,
Leao

No it isn't something I have ever seen in the BIOS. I know it can take a while to get a sensible answer from GGTS so you will just have to keep asking. Good luck.

I would think gigabyte would want to keep it simple and have all VT types under “Virtualization Technology” option. My guess is there is a set bit needed for the VT-d as a way of enabling it and disabling so you may get a BIOS sent to you...and then how many other boards have this problem...

Edit: Arr...this might be a problem for your G31..

Yes.. I have confirmation of GGTS , my MB doesn't have Vt-d support.

I ask for models name of MB with Vt-d support, because there is no information on any product page.

Thanks all.

Thanks for getting back to us with the info. No doubt it will help someone else in the future. It would be a good idea if more info was incorporated into the manuals.

Do you read my post?

Your motherborad G31 chipset - doesn't support VT-d.

chipsets which support VT-d are:
Q35 / Q45 / X58 / 3450 / Q57

but I only know that INTEL's motherboards 100% support that, GIGABYTES - not testing, and I don't have money that buy and sold motherboard which don't pass test. I want to buy GA-Q57M-S2H (supprot IDE, HDMI, more cheaper PCI than PCIe, more SATA, optical interface and HD audio  on back panel) - greate motherboard but this is too much risk for me  because GA-Q57M-S2H only have in bios VIRTUALIZATION TECHNOLOGY -> what does it mean? VTd/VTx/VTc? May be All, may be only VTx as that in greate motherboard with support USB 3 -> GA-H57M-USB3

thats why I bought Intel DQ57TM (don't have HDMI - have only DisplayPort and DVI - optional adapter cables cost ..., only have 1xPCI and 2x PCIe, only 5x SATA, have only on motherboard pins option S/PDIF, HD audio - in Gigabyte all this funcion you have in standard)

There is nothing stopping you from contacting GGTS or Gigabyte sales and querying the points you require answer to with them prior to making a purchase

Hi all,
there is an answer from GGTS:

""
Thank you for supporting GIGABYTE products and contacting GBT Tech Support. As long as the motherboard with intel Q series chipset and has Intel vPro certification that can be support to vt-d technique. About the model suggestion, you may take GA-Q35M-S2, GA-EQ45M-S2, GA-Q57M-S2H for your consieration.

cheers

Well not in the best English but the message was clear enough, only use one of those motherboards listed with the Q prefix. Thanks for sharing the info.
