Good results on 3DM FS
. Cheers for ROM, the last Nitro ROM I looked at they have a small voltage offset already in ROM. On mobile at present but will check your ROM later.
To see if you have an offset now, whilst on stock ROM/no OC check your idle voltage, are you at 0.900V?
In Fiji bios mod OP
is section showing how to use AiDA64 to gain VID per DPM, can you run this and attach results txt to post? I suspect you have low DPM 7 VID which is allowing you to add more before you hit negative performance scaling with voltage increase.
Also use MSI AB to gain i2cdump if you don't mind, again info in bios mod thread OP.
