Hope i am in the right place if not please refer me to appropriate section.

I have a table with set values, the only thing i can change is MEM CLOCK between values 800/667/533/400

See mem clk.png for table

What is the formula for X(Tcl),

Wat is die formule vir X(Trcd),

ect...?

I need to use it on larger values than 800

If anybody can help, I will greatly appreciate it.
