How to verify cpu’s hardware virtualization?

I recently bought an Alienware Aurora system that came with windows 7 ultimate 64-bit and an i7 980x Extreme. For the past few weeks, I had successfully installed mac os snow leopard under windows 7 with vmware workstation, had no problem surfing the net with safari or programming iphone apps with xcode. Then all these good things came to an abrupt end yesterday, when I was suddenly greeted with this message when trying to run the Mac OS virtual machine:
"A virtual cpu has entered the shutdown state. This would have caused a physical machine to restart......."


At first I thought some of the windows updates might’ve broken vmware workstation, but after 2 clean installs of win 7 and still getting the same error msg, this became less of a possibility. Then on a whim, I took out the 980x cpu, and put in an i7 960 on loan from a friend. Lo behold, VMWare worked again, no more errors.


So I think there is a high probability that there is some hard-ware related defect with my 980x, though I’m not ruling out the possibility that some features on the cpu might have been turned off by accident and can be turned on with the right software. Furthermore, with the exception mentioned above, my 980x hasn’t shown the slightest problem with any other software. Therefore, I don’t think Alienware/Dell tech support would readily agree to an exchange of cpu just because mine has trouble with one specific program, I might have to demonstrate with incontrovertible evidence that my cpu is defective. To that end, I wonder if there’s any CPU verification program that checks if all the features on a cpu, say hardware virtualization, are working properly. To check a cpu’s arithmetic is quite simple, ie running prime95 for a few hours, but I don’t have the faintest idea as to validate hardware virtualization.


TIA for any help.

You have the most current BIOS? If it does not detect the cpu correctly then that could be an issue as well.

My bios is up-todate. But I don't think it's bios-related because when I swapped in a different CPU on the same mobo, everything worked fine.

For the easy answer to find out of an Intel® Processor has hardware level virtualization you check this site http://ark.intel.com/Default.aspx. For your processor you can scroll down and find a listing for Intel Virtualization Technology (VT-x) on this site http://ark.intel.com/Product.aspx?id=47932&processor=i7-980X&spec-codes=SLBUZ. So in this case the Intel Core™ I7 processor Extreme Edition 980X does have hardware level support for virtualization.

I think the issue is knowing when it is enabled successfully, not whether the CPU has the feature or not. IE, is the OP's CPU flawed or broken in some way? How would he make a convincing case of this to Alienware support?

putting the CPU in another motherboard to see if it still happens?

Thanks to all for your help.

My little update:
1. I downloaded and ran "hardware-assisted virtualization detection tool" from MS, the report says my 980x has hardware virtualization and it's been enabled.
2. I put my cpu into my friend's mobo, and was met with the exactly same error message from VMware workstation, though his i7 960 had no problem running Vmware on my mobo.

So I think it's fairly safe to conclude that there is something amiss with my 980x, though I'm not sure if that something can be reversed with software. Also, the detection program from MS may just check if certain bits/flags are set, without performing anything indepth. What I need is a program that can specifically target a cpu's virtualization features and put it through paces, TIA for any suggestions.

Cool table, but it should also list other things like whether or not the CPU supports VT-d and EPT.
