Xeon Phi causing PC to freeze

For some time now, my PC has been freezing periodically - about once every 2 days, the screen looks normal, but mouse, keyboard etc. do not respond and I have to hold the power key in to restart.

By process of elimination, the culprit appears to be the Xeon Phi 3120A card - I just took the card out and ran the PC for a month without a freezing incident.

Put it back in and it froze the same day.

I have tried it in both possible expansion slots - froze with both.

Have a beeping problem with new ram memory - 4gb.

          

i think its about performance of computer.

beeping , and no display.

According to this, my destop board could accept memory stick, but pratically not.

Co-processor only fine. But Symmetric & Offload not work.

Hello, I want to generate xeon phi workstation using intel MPI.

Thus, I've already set up xeon phi and run test code using below thread.

However, MPI Offload model & Symmetric model is not working with this error message if I run below MPI task.

Booting a Non-Linux OS

I want to boot a non-linux OS on the Xeon Phi. Is there any documentation on that? 

From the MPSS User Guide:

"The second part of the boot argument indicates to boot a Linux* image. It may also be set to elf to indicate booting a standard ELF format file. Documenting non-Linux* boot is beyond the scope of this document."

Is it possible to boot an elf-x86_64 (no unsupported vector instructions used) or does the elf need to be an elf-k1om? What is the entry point of the elf and can it be used to bootstrap the card OS?

Energy consumption big differences for idle energy consumption on CPU and Xeon Phi coprocessor

I tried to test the idle energy consumption for 10 seconds on Xeon Phi 5110P and  Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz energy consumption. 

I found there is a quite difference on total energy consumption for 10 seconds. This is weird. 

 20.321426 Joules for 10 seconds idle CPU Intel(R) Xeon(R) CPU E5-2650  which is 2.032 Watt. 

While the Xeon Phi 5110P is 764.650000 Joules in 10 seconds which 76.465 Watt. 

The detail codes and compile method can be downloaded in the following two links.
