I don't have "The knowledge" for good procedure on this but I found by trial and error and reading some that these will run tRAS= CL + tRCD + 2. tRRD will probably go quite low (even as far as 4). tFAW = 4 * tRRD.
Try these 1 Step at a time though because I may be mis-remembering settings from other speeds
I think that I had no bandwidth increases below tRFC of 128
I wish I had some screen shots but I'm running some other tests for the next week.
Just have a play with it then run AIDA64 Cache and ram bench then play some more.
If you just cannot get it stable try enable PLL overvoltage because I am thinking that the threshold at which this kicks in automatically might be a little high.
I had success in stabilising by taking vccio up too but that was definitely when trying for 2133 9,10,10
Hope something here helps.
