TRAS Cycle time Question

post #1 of 3
Thread Starter 
I am running G.Skill 2133 F3-17000CL9Q overclocked to 2400 at 10 11 11 28 1T and have tried a tras today of 12.Is there any advantage of running it low like 12 or would it be better to keep it at 28 like where I had it before. Seems stable though with prime.

Keep the tRAS = CL + tRCD+tRP (+/-1).

Although in the DDR days I used to run it at 0 (zero!).

There is no general "formula" on optimal tRAS value for general case - it really depends on what is best in a particular scenario.

Usually, tRAS doesn't make much of a difference for both performance and overclocking so you might as well leave it alone if it's not causing any stability issues.
