huge difference in CPU score on Time Spy changing mem to C18 from C19

[Apone70]

Ok so i run my 8pac 3200mhz memory at 4000mhz C19-19-19-39. If i change it to C18-19-19-19-39 my cpu score on 3d mark drops from 8865 down to 6641 (8700k at 5ghz). I was just wondered if anyone knew why as its a huge drop, the system is still stable.

This thread reminds me of Aesop's Fable 'The Tortoise and The Hare'.
