Hello,

I looking to buildapc with Vt-d enabled(because i use Virtual machines alot on top of the OS) i need some help in understanding Vt-d on Motherboard vs Processor.

The processor i choosed was i7 4770 which is Vt-d and Vt-x enabled. If the processor is vt-d enabled do i still need the motherboard with Vt-d enabled?

I looked at some of the intel motherboards compatible with i7 4770, I saw some differences in virtualization on mother boards i have choosed (Intel DQ87PG, DH87MC, DZ87KLT-75K). The comparison chart on the Intel Website shows that DQ87PG is VT-D enabled but the others are not. http://ark.intel.com/compare/70898,70903,69045

So my question here is If the processor is Vt-d,Vt-x enabled do i still need the motherboard to have Vt-d enabled in order to run virtual machines on top the OS?

Yes, the motherboard also needs to support Vt-d in order to use it. You can still run virtual machines without it, though.

Why are you only looking at Intel motherboards? Intel has signaled it's intention to get completely out of the motherboard business in a year or so. Go with a company that will be making motherboards for many years, such as Asus, Gigabyte, or MSI (among others).

Thanks for the suggestion but i have looked for the Asus and Gigabyte as my options but on there models i didnot found if the motherboards support Virtualization or not. Even i didnot found the Max TDP on there motherboards.

look at Q87M-D2H from Gigabyte, I'll plain build box with vt-d on it in a week

I am facing a similar situation. How was the performance of the Q87M-D2H from Gigabyte?
Thanks

Motherboards typically don't publish TDP. That's a CPU parameter, it doesn't apply to motherbaords, which is why you can't find it.

I am in a same dilemma.

Want to build a PC for virtualization (for running VMware/Hyper-V). I have decided to go for Intel i7-4770 Processor but confused about Motherboard. Was looking for Motherboard with Q87 chipset and VT-d support but unable to find.

Can anybody please suggest me a good motherboard with VT-d and 32GB Mem support.

Thanks,
MG6

I have a Z87-based motherboard that supports virtualization: MSI Z87-G41 PC Mate (MS-7850). I could be wrong, but I don't think a motherboard has to do much except not interfere with the CPU's virtualization technology. At least I've only ever been concerned with the CPU regarding virtualization capabilities.

My MSI just has one setting in UEFI/BIOS, to enable Intel Virtualization technology:

[From the manual]

Intel Virtualization Tech [Enabled]

Enables or disables Intel Virtualization technology.

[Enabled] Enables Intel Virtualization technology and allows a platform to run
multiple operating systems in independent partitions. The system
can function as multiple systems virtually.

[Disabled] Disables this function.
