I hope you don't mind me taking your PM to thread
, reason I'm bringing it to thread is so anyone else wishing to know the same has info and I'm not repeating same thing via PMs to others
Also by bringing things to thread means others can view/chime in and some things bring up holes in my own post 1. For example how you stated your strap info which brought about me stating we can edit frequency and I should add info to post 1.

This is what I saw in your rom.
No you've interpreted image wrong in post 1 heading Memory Interface (RAM I/O bus voltage) VDDCI and frequency editing
The VDDCI voltage and frequency are turquoise boxed values, you seem to have picked up the unmarked/orange boxed values. The text in image is same colour as marked values to denote what goes with what.
If searching like you are first rule of this mod is the frequency will be same as what is default highest RAM frequency of a rom. So lets say rom has 1250MHz, this becomes 125000 > 01 E8 48 > 48 E8 01.
Second rule is if VDDCI is shown as 1.000v in GPU-Z sensors page when stock rom flashed and no modification of voltage has been done via an OC app (AUX voltage in MSI AB) or hard mod, this means 1.000v becomes 1000 > 03 E8 > E8 03. We can't take other voltages out of GPU-Z as absolute, for example 1.050v set in rom shows as 1.047v in it. For cases where people see higher than 1.000v VDDCI I suggest they view the PowerPlay table and pick out SCLK (GPU Freq.) & MCLK (RAM Freq.) as shown in image post 1 relevant heading.
So search would be 48 E8 01 E8 03 , I still suggest cross ref'ing tables for a rom created via AtomDis so you know you're in the PowerPlay table.
For example in the tables I created for your master rom, heading data tables:
000f: a572 Len 0288 Rev 06:01 (PowerPlayInfo)
What that means is offset location a572 is where PowerPlay table start in rom, it has a length of 288 hexadecimal. Press CTRL+E to select whole block using that info, this way you'll see range of hex values for complete table in lower status bar, A572-A7F9. Now when you search for hex values if offset for found values is within that range you're in right table.
You can also press CTRL+G and enter a572 to go to beginning of table and then start search via pressing CTRL+F and entering hex values plus set Datatype to Hex-values.
Setting the frequency via this mod doesn't gain any performance, I set it the same because stock roms do this and I wouldn't want to chance introducing instability to a modded rom from not doing this.
