Quick question with memory timing settings

[Exposal]

I'm not huge into memory overclocking and such but i've always liked my memory at 1866 with 9-9-9-24 timings so that's what I always put it at. I was wondering about the TRFC being at 281 clocks, is it bad that it is this high?

 

 

 

 

 

Any help would be greatly appreciated
