By default my DFI NF4 board uses 3120 since that is 15.6us and 200MHz divider. Alot of people are recommending the 3684 tRef for my RAM but thats 15.6us and 233MHz and that doesn't make sense to me. I dont get why this has to be so difficult and why there isn't an accurate way to calculate it outside of just randomly testing numbers to see what works.
