Re: DDR3 -KC705

Hello @rajuponnaganti,

 

I would look at the KCU105 User Guide and start with the Clock Generation section:

https://www.xilinx.com/support/documentation/boards_and_kits/kcu105/ug917-kcu105-eval-bd.pdf

 

There they talk about the clock sources, how they're generated, and gives a description on how to change them in the Programmable User Clock Source section. With this information you will be able to change the MIG system clock to 250MHz.
