Adding Ram Causes Games to Crash

Hi I recently purchased the Novatech Reign Sentry MKIII of which I’m very pleased.
I decided to upgrade the memory to 32 GB by way of two more 8 GB sticks so I purchased from Navotech another two identical sticks Corsair Vengeance LPX DDR4 2 x 8 GB 3600 MHz (kit). When these are installed, during game play the games freeze. I have tried various games and I see the same issue.

I have made sure that the memory is of the exact same type as seen in the BIOS. I have also place only the new memory onto the motherboard to ensure that the new ram is good.

Has anyone here know of a fix for this?
