16 gb ram upgrade problem

[mir_1]

so i made a pc build everything was fine except for 1 ram that was broken so i installed 12 gb of ram instead of 16 and everything was working fine.
now i changed the broken ram with a good one, same model same size.
at the beginning windows wasn't even starting so i loaded default values in the bios.
the problem is that now after a while that i play a game it crashes and i don't know why, i suspect is the ram since i only changed that.

the mobo is the asrock z170 gaming k4 and the ram is 4x4 gb hyperx fury @2400.

do i have to do anything in the bios before i can run 16 gb when upgrading to 12 gb ?

Test each stick of RAM individually (remove the others and leave only one).

Post screenshots from CPU-Z memory and spd sections.

Try setting manually memory settings in BIOS (values from JEDEC #7).
That is changing CL from 15 to 16.

so in the bios i set like 16-16-16-35 ?

Start with 16-15-15-35, after that you can try your setting.
