I'm having some issues with undervolting a rx470 nitro 8g oc. I followed this vid to add a voltage offset.

After opening the rom in srbpolaris, i can see the offset is detected as i can click the dropdown, but after flashing it, it has no effect whatsoever. I've tried it with the vddci mod as well, but the voltage does not change Sad After flashing i used ddu to clean driver, had no effect either.

Changing gpu/mem clocks with srb works fine, so i'm not sure what the problem is..

This is my original voltage object:
Code:
42 00 03 01 01 03 0E 00 10 96 20 00 00 00 00 00 FF 00 01 07 0C 00 0E 00 00 00 00 00 00 00 04 00 24 00 00 04 00 00 02 80 10 00 00 00 10 00 52 03 02 00 00 00 84 03 02 00 10 00 B6 03 00 80 10 00 E8 03
This is my modded one:
Code:
46 00 03 01 01 03 12 00 10 96 20 00 00 00 00 00 8D 00 F4 00 FF 00 01 07 0C 00 0E 00 00 00 00 00 00 00 04 00 24 00 00 04 00 00 02 80 10 00 00 00 10 00 52 03 02 00 00 00 84 03 02 00 10 00 B6 03 00 80 10 00 E8 03
I used lard's table calc to fix the offsets of all other tables. After doing this I compared the dumps from atombiosreader and saw that the length of the voltageobject indeed increased by 4 bytes, and all tables after have the same length but an increased  offset.

Can anyone explain what i did wrong?

This is my entire rom
