P150EM and vt-d support?

Computer: p150em w/bios 1.00.04LS1
CPU: i7-3720qm
OS: Windows 7 Home Premium

When I run CPU-Z I see vt-x but not vt-d. I chose this processor because it offers vt-d. Does anyone know:
Is vt-d enabled in the bios?
Do I require Windows 7 Professional?

 

There is an option in the BIOS but it should be enabled by default.

have you tried to actually run vt-d even though it says disabled

about windows professional, i dont know if it is required, i hope not

 

I read that vt-x was only recently enabled in the latest bios. I wonder if vt-d needs a BIOS update as well?
I ran the "Intel Processor Identification Utility" it showed VT-x set to Yes but there was no VT-d feature to say yes or no.
I'm wondering if somehow this motherboard doesn't support VT-d. I'll try to run ESXi off of a spare drive and see if it detects it.

Yeah, I think I was confusing after reading about hyper-v tools. I don't think the OS version should matter if using vmware products.

 

I feel you guys would know how to answer this:

I tried searching this but I can't find a straight forward answer. What is VT-x and VT-d? What is the difference and what are they used for?

I've tried using VMWare before and Windows XP Mode to run older versions of Windows on Vista 32bit and 7 64bit. I've some issues with hardware being recognized (such as video and audio) to run certain old programs that don't work on Vista or 7. I'm using an Intel T8100 which does have VT-x.

Thanks for the help!

 

Yeah i would always recommend the latest BIOS. funny i read the same thing about Hyper-V. but like you said i dont think it matters here
The Motherboard definitly supports vt-d though.

oh btw as i was looking for vt-d enabled programs, i stumbled upon esxi,can you tell me what exatly it is and how it is different from vmware workstation? i dindt quite understand it. i think its more for servers an not home use...

Well i dont know exactly what vt-x is but i think its just for virtual machine support in general, dont quote me though...

As for vt-d, it enables you assign periperals directly to the virtual machine eg. using your wireless card directly in a vm without a NAT bridge

VMWare workstation/player, which you were probably using doesnt support vt-d though, the only vmware product that does is, as above mentioned ESXi.

 

In a nutshell (as far as I understand it):
vt-x: Allows you to run 64bit guest OSs. It speeds up emulation also.
vt-d: Allows you to directly assign physical devices to the guest OS.

When you run ESXi on a host with vt-d you can select which devices you want to passthru to you guest OS. For example, you can install a version of Windows and passthru a device like a network card. Windows would see the real network card (not a vmware version) and install the real drivers. This would give you REAL performance. Think about this for graphics cards!

In the not to distant future vmware workstation will probably allow you to passthru your second graphics card to the guest OS. For p150em people like me that means I could passthru my ATI 7970m card! Windows, Mac OSX, Linux would all see that card and accelerated 3D graphics would be achievable.

BTW: I installed ESXi on a USB stick to test my P150em. It allowed me to passthru my ATI card but I didn't have time to install an OS to actually try it out yet.

I still wonder why CPU-Z and other programs are not seeing vt-d. If it works in ESXi then I'm wondering if I really need Windows 7 Professional. I hate to spend the $80 on the anytime upgrade to find out I'm wrong.

 

I have windows 7 pro and 3720qm and my CPU z does not show VT-d support. Looks like Clevo need to enable it in p150em bios... whilst they are doing that they may as well enable XTU ;D.

 

It must be enabled in the bios since ESXi can see it. Why CPU-Z and other programs can't see it is what puzzles me.

Can someone with Windows 7 Professional and a supporting processor run CPU-Z and see if they see vt-d support?

 

i have windows 7 pro and my CPU-Z said I have no vt-d support. Maybe its a bug in CPU-Z...

 

Thanks, that helps. I sent an email to CPU-Z to figure it out... Thanks.

 

I have Win7 x64 ultimate, and the specs in my sig. According to HWiNFO64, if I check on the processor and scroll down to the "CPU SNB Features" it says that I have VT-d. CPU-Z only shows VT-x, though.

 

strange. i think its a cpu-z problem then

 

sorry double post

 

Thanks that's helpful. I just tried that program. It shows that I have vt-d also. I just wonder if it's actually testing it or just assuming it based on my processor model.
I'm trying to hunt down the code to test it out for myself.
