I have the same issue.
but, the test passes if I un-check the cache test item in the test configuration software,
Windows 8 x64 Pro latest updates.
CPU: Xeon E3 1265L v2
GPU: Matrox g200eW on motherboard
RAM: 16GB (8GB x 2)
Maybe Hyper-V ? Yes I am using Hyper-V.
We haven’t heard about any problem with this software; however I’m going to check it out and report it if it's necessary.
In the mean time, you may want to use a 3rd party software such as CPU-Z.
It is possible to have a defective processor, so in order to find out if the unit is or not defective you will need to troubleshoot the system with minimum configuration (processor, motherboard, power supply and 1 memory stick)
Also, make sure your motherboard has the latest BIOS version.
You may want to do a clean installation of the Operating System using the latest drivers, in order to discard if this is a software issue instead of a hardware failure.
If you continue having the same behavior, feel free to contact your local support group for assistance on replacing your product http://www.intel.com/p/en_US/support/contact/phone
