To get 1300mhz on memory I had to drop to 2T. loosen secondary tertiary sub timings. Below SS is 250% memtest.
1333mhz fails to boot, I will try 1.65v+ again (dropping to 1.635v actually gave me more stability for 1300).



I don't know whether to increase VTT or VCCSA first?
My kit is 1400/x400 - Hynix.

edit: Forgot to try tRCD first... I'll try loosening that.
