Xeon Phi (KNC) + Core i3?

I was presented with Xeon Phi 7120P. I tried it on ASUS P9D-C/4L mobo (option "Above 4G decoding" enabled) with Core i3-4370 CPU. Device detected, but did't initialize by MPSS. Maybe, it cannot work with Core i3 CPU?

there's no reason an i3-4000 cannot support a KNC, as far as I know.

You say "device detected but not picked up by mpss"

Which OS are you using? Can you run 'micdebug.sh' (Linux) or the Windows equivalent and post the output here. That might give a clue as to what is failing.  My main suspicion would be the power supply or cooling fan of the board - a 7120P KNC uses quite a lot of power and requires STRONG active cooling (as it does not have a fan of its own)

I tried CentOS 7.4 - 6.4.

Ok, as soon as I assembly  my test-stand back.

Rachko,

...For KNC P means heat sink supplied, you supply the fan. I use dual 5100P's and built my own fan ductwork and selected appropriate fans.
