well... what wrong on my setup for try to play CL5 & CL6 on this board ??? i have better results from CL6 over CL5 at 2400MHz and PSC chip
and for other subtiming all same setting

2400MHz 5-11-8-24-1T, 1.85V (air )


2400MHz 6-11-8-24-1T, 1.85V


and.... not only on high frequency of RAM to see different but i back to try with normal clock at 1600MHz compared by 5-9-9-24-2T and 6-9-9-24-2T
(used 2T for lower Vdimm ) all subtiming are same and it same case like above CL6 still better over CL5 and big different as well for Spi32M from two time running

CAS5 - Spi32M first run 07.31.044s | second run 07.30.685s


CAS6 - Spi32M first run 07.28.907s | second run 07.27.845s


btw. 1.15D nice one for PSC ram kit Nick
