SOLVED:

Would like to appreciate Yann for helping out.

As mentioned by him above - GA-7PESH3 supports E5-2600 V2 processors only with RXX versions bios firmware.
So new motherboard needs to be upgraded before installing those CPU's.

In my case motherboard was sent to Gigabyte Service Center in Netherlands, where they've updated the bios.
Now everything is installed and working.

Thanks Yann.
