I've a 1600, a taichi and lpx Hynix 3000 c15 @2933 cl16.
Now, after all the study and the readings on the platform, and on taichi in particular I would have thought that LLC1 (wich gives a straight reading on SVI2) or LLC2 would have been better to obtain the best overclock and stability.
For myself the experience has been quite the opposite!
LLC5 stabilizes what LLC1, 2 and 3 can't achieve in anyway.
I use occt Avx 64bit linpack for 1.5hrs quick test, occt cpu small and medium, and prime 29.1 for medium cache stress.
I am not even sure anymore wich readings I have to believe since I am stable at a 1.337v on SVI2, but supposedly 1.36 on vcore reading @3950mhz all C states and power stuff disabled (1.387 setting in bios)
I'll continue discending in voltage and testing but for now, I can advise you all stable with LLC2 and llc1 to try lowering voltage and testing with LLC5.
Temps are better and Oc seems too! On noctua NH d14.
I ll keep you updated.
Ps. With ram, no luck with 3200 with any setting but the bclk wich I volunterly didnt touch for now
