I also spent almost two days already on this matter and it is though indeed...
I think I could identify RAS and CAS timing 32 bit straps and also some of the individual timings in them, but...
I can't find the Hynix AJR datasheet, (i'm using the AFR one), and I also can't find the register reference guide for the polaris GPU (or even the Sea Islands series would be great).
Any hints?

Code:

TRRD 23:20 4bit Number of cycles from active bank a to active bank b
