I am not an overclocker and expert at all, but reading from this community I have been able to do a few tweaks on my Gskill CL26 6000 kit and have been able to achieve these numbers 67.2ns. Any other simple suggestions I can do?

I simple did EXPO, disable power down mode, tREFI to 65535 and tRFC to 480.

Thank you in advance 👍
