@MiniMe, I am attempting to construct an Excel spreadsheet using recommended ratios (or relationships) between graphics card parameters as was touched on in this thread: Initial Ratio Definition.

Rules:
  1. Core Clock (CORE) to VDD (Core Voltage) ratio 1.75.
  2. Core Clock (CORE) to Memory Clock (MEM) difference to 480 Mhz.
  3. Memory Controller Voltage (VDDCI) to Memory Clock (MEM) ratio is 2.14.
  4. Memory Voltage (MVDD) to Memory Clock (MEM) is 1.41.

Spreadsheet formulas
Core Clock (CORE)Core Voltage (VDD)Memory Clock (MEM)Memory Controller Voltage (VDDCI)Memory Voltage (MVDD)
Input value like 1380= (CORE / 1.75)= (CORE - 480)= ((MEM*2) / 2.14)= (MEM * 1.41)

Basically, I am trying to create a spreadsheet that auto-generates values (VDD, MEM, VDDCI, and MVDD) when I input the Core Clock (CORE) value. But based on the recommended ratios from https://www.igorslab.de/community/threads/gigabyte-5700-xt-bios-mod-fails.3304/post-86493 , the numbers in the spreadsheet differ from the values at the bottom of the post. I am trying to understand the reasoning for these differences, as well as get some feedback concerning making such an Excel template. Thanks!

The values at the bottom of the post are approximate ones,

As the quality of the components of a card most likely differ from each other cards, the ratio of the voltages in the guide may not applied to all cards and the average value of the ratio between the minimum and default might be a good approach that may fit most cards.
