Secondary timings

[UltraTaco]

How are those calculated and set? They're all set on auto and if you keep pushing ram higher, there's one particular timing that goes from 139 to 174 then 228. I don't remember exact numbers, it it doesn't matter. How are those picked?

For example, my ram is 667(ddr3-1333) and pushing beyond that main timings stay at 9-9-9, but that other one keep increasing. There are no jedec specs beyond 667 on my ram

Any thoughts?
