Look at this thread:

An Asus moderator says:
Update on this case:

My Asus contact confirms the enabling of VT-D is not complete due to chipset limitation (cannot pass all test items via Intel VT-D test tool)

After discussing with Intel FAE, it has just officially confirmed to my Asus contact that the VT-D support mentioned on the Intel's own P67/H67 board spec page is a misprint, and will be removed to avoid further misunderstanding.

The official support for VT-D begins from Q67 series, and so is vPRO.

For your reference.

Quite disappointing.
 
Yet ASRock and Biostar P67 motherboards support it just fine...

What's VT-D? I'm a nub.

It has to do with virtualization, meaning if you want emulate another OS on top of your installed OS. Its a pretty important tool for software developers and IT people. VT-d simplifies the abstraction of your hardware (mainly I/O devices) so that the virtual OS can use them. If you aren't doing any of that, you can leave it disabled within your bios.
 
I've known about this for a while. All these little "gotchas" really turn me off of intel. It's funny that my multi-year-old Q6600 & DQ45CB has better virtualization support than something released in 2011.

Don't get me wrong, I'd love to have SB setup (And I may go for a 2400/2400s anyhow) but the intel "market segmentation" stuff is a huge turnoff.

Edit: Doesn't X58/ i7-9xx support VT-d?

yes x58 / i7-9xxx 1366 socket cpus support vt-d.

Thanks for the info, I definitely won't be using VT-d.
 
Not sure I understand this. Aren't the majority of boards sold going to be P67, just like P55 in the previous generation, with X58 and X68 covering the enthusiast markets?

Exactly how many Q55 boards were in circulation in the S1156 days?
 
Corporate and OEM sales dwarf retail sales. They will not be using P67 motherboards, as they do not require the OCing feature.

Seems like ASRock VT-d support is semi-fake. I have read many people complaining for their inability to have them working correctly, in practice.

Yeah, you're right. I'm not an overclock freak, no interest at all in fact. So I bought an i7 2600 (non K version) because of its advertised support for VT-d extensions. I'm a software developer so it could be very handy for me. Now imagine my face in reading those news... :mad:
