Hi,
I am having issues getting my Gskill ram to its max speed of 3200mhz. I have successfully got it to run at 3000mhz but if i take it any higher my PC fails to post. Mobo is a Z270F and CPU is I7 7700k.

First question is is it even worth taking it to 3200mhz? Will the extra 200mhz make any difference?

Second question is obviously any ideas how to get it to work?

Thanks.

Can you try the following

Set VCCSA & VCCIO to 1.15v - 1.2v

Relax CAS, tRCD & tRP by one clock

Set DRAM voltage to 1.4v
