Thanks for those links.

I wonder if SPDTool, whose download is from early 2014, will work with DDR4. I'll see...

EDIT: Not working on my Z270 PC, will try with Ryzen.

yes i do have the cpu oc mines at 3.9 also
now i USED to run it at 1.3 volts fixed
but it seems apperent now theres more luck in a little extra juice to cpu vcore when pushing the ram
so at the moment im running 1.325v at 3.9
 (for reference the temps difference between 1.3v and 1.35v when i was testing over the weekend were an extra 6 degrees C using a noctua heatsink and fan)

i will try to gently drop the volts back down when i feel sure i have a stable ram overclock and update you with my findings

ive set the proc-odt at 53.3 ohms, as a tester it seems ok ,i choose that as it seemed most people used it with sucess ( and yes i couldnt agree more ,we need people to share experiance with what works with what boards and ram brands, to enable us to learn)

i have to set geardown to enabled with the taichi or it will always give me the cold boot loop of death, this seems to be echoed with others on the overclockers taichi thread

so basically at the moment my cl15 ram is
set with xmp
change the first 4 timings to ALL 14 then leave the rest at xmp hence the 35/50
i have however changed the trfc
trfc 1st =312
trfc 2nd = 192
trfc 3rd = 132
geardown = on
bank group swap = disabled
bank group swap alt = enabled
proc-odt = 53.3
dram volts 1.375v (need to lower)
soc 1.05v (need to lower)
vddp 1 volt (need to lower)
vtt-ddr 0.700
cpu vcore 1.325v (need to lower)

future plans :
get the voltages down a bit
test at 3333 mhz
tighten a few more timings *step by slow-step* (using stilts and chews profiles)
