Working on tightening my timings, mainly secondary at this point, and I keep seeing people mentioning rules that many don't seem to follow. Like tRAS is supposed to stay above CL + tRCD + 2, but I've plenty of people drop tRAS to the floor without issue. I've seen a similar formula for tFAW. And for stuff like tREF and tRFC what increments am I supposed to move those in? They're both such random numbers it makes me feel like they're supposed to follow a formula.
