ok here is a table for u guys to understand

take note its only possible to find ure scaling and vtt/dram ratio and vtt/vcore ration when u have a very strong confirmed base

for mine after 4-5 boards
my bclk 200 confirmed



if u notice the downward/upward trend is to maintain the scaling
if i change and confirm one voltage i need to adjust the other two to make sure it stays on that trend

also this is how i also sometime question ppl voltages when they post a setting without a screenshot that goes against this trend.
the trend is like ure upper/lower limits.
