Got my 32GB kit, I was in the past 3 days trying to solve one big problem that was driving me to think that I lost so hard at the lottery, see what happened:
1 - 4000CL16-16-16-36 1.40v XMP kit, can't get stable anything higher than the XMP frequency, even with just primaries at 16s and AUTO subtimings
2 - 4000CL15-15-15-36 1.45v VDRAM all subtimings tight was stable, lead me to think that this kit was binned at it's own limit on XMP and doesn't like frequency past the XMP one
3 - Went back to trying 4200CL16 again - VDDQ AUTO (set to 1.50v) and SA from 1.25 to 1.40v manually and also SA AUTO (set to 1.32v), VDRAM from 1.45v up to 1.60v, nothing seems to make 4200CL16 or 4100CL16 work, even with all AUTO subtimings, just primaries set, observed that 1.42v VDDQ was showing BSOD while trying to boot, 1.45v-1.50v boots normally, but errors in TM5 as usual
4 - So one last thought, I remembered someone mentioned here was using 1.35v VDDQ and the fact that I was having BSOD with 1.42v made me thought to never try below 1.45v, so I decided to try 1.35v just for the sake of it, surprisingly it boots, but again errors in TM5, so one last try was to set 1.30v VDDQ, and for my surprise I was able to pass 1 cycle of TM5, now for some reason that I have no ideia, 1.45v VDDQ is fine for 4000CL15 but intolerable for 4200CL16, it HAS TO BE set to 1.30v VDDQ, now knowing this I will try to reduce primary timings further, since the rest is already tight.
