I have been reading up on RAM and testing different settings for my RAM (Corsair Vengeance 2x 4Gb, 1600MHz, CL8), and I'm wondering what the real difference is between CAS 8 @1600MHz and CAS 10 @2000MHz is.
Aren't they effectively the same thing? Is this math correct? : 1/(Frequency*1000)*CAS= nano seconds for access or change in data. eg, 1/(800*1000)*8= 10 nano seconds? same value for 1000MHz with CAS of 10.
What happens in the time where there is waiting for the next cycle? This must be where the difference in performance is.
Help to understand this is greatly appreciated.
