@DV8tion all of the subs will be up to you to figure out for your particular kit, Patriot B-die in particular seem to be all over the board, every sample is different. I've had their 4000CL19, their 4133CL19, and two 4400CL19 kits and the differences are wild
the subs you want will depend a lot on the VDIMM you're willing to run.
@jesdals runs a tight setup at 3800CL14 but also runs basically over 1.6V (Gigabyte minimum 0.03V overvolt on ever board). Mine 14-14-14 costs me 1.55V but if I relax tRFC and 4/6/16/4/12/12 and 14-15-15 I can come down to 1.5V, and 15-15-15 is only 1.42V.
