Successfully crossflashed my Galax A320M with Galax B450 BIOS, but need some help

M.2 ssd still works, got TPM2.0, unlocked pstate overclocking and XFR enhancements.
I need a little bit of help though. The iGPU overclocking doesn’t seem to be working no matter what I try.



Difference between old bios and new bios CbsSetupDxeRV iGPU overclocking section

The original BIOS supposedly had all these settings but they were hidden and weren’t visible in AMIBCP and working with hex to enable them is beyond my capabilities.

I checked in HWinfo and GFX core voltage and GFX clock freq didn’t have any effect, as an iGPU gamer I really want this to work.
