I found the 4th and 8th word equation on wikipedia and I added it to my excel sheet. So I am making a thread where i will keep it so please share it so people cna figure out exactly what RAM they want. I'll update this as I use this but its fairly complete since i can do all the major words now and you start to see some cool things in regards to MTs affecting 4th and 8th word latencys. It is interesting how DDR4 vs DDR3 can really help in regards to having higher BW.
I am curious on what a word is though and how it relates to actual data and access times. Can anyone answer that? I have been wanting to know how BW may affect access time for larger files and where file size changes from being latency dependent to BW dependent.
It aint pretty but no one else made one so deal with it

UPDATED LINK: if it goes down just post in thread or PM me.
The new 3200MTs CL 14 is comparable to 2400MTs CL 10 so DDR4 highend is matching highend DDR3 now. That new DDR4 released January IIRC. There were some magical DDR3s in the past supposedly that has better latency but I have never seen them in the wild so those 2 speeds are for the most part the best you can get ATM.
