Yes, even unplugged all cables totally, reinstalled drivers with DDU multiple times, still the HBM voltage was stuck on 1.275V. However, on 1.275V I did not notice any adverse effects compared to 1.3V. Could be that the negative impact is less pronounced or visible when it comes to ram, compared to too low voltage on core, but I did not have any issues at all.
I have traded my Fury X for a Vega 56 (+some extra cash of course), so this will be a non issue for me very soon anyways. I did buy the Gigabyte Vega 56 OC however, which can be a problematic card as far as I can tell, judging from reviews on the internet (might explain why it is €100 cheaper than other aftermarket Vega 56's
) I will put the card through the wringer, update to the newest BIOS, undervolt, etc, to quickly flush out any instability. If there still is instability with this card, no mater what I do, I will still have two years of warranty left (card came with three years warranty).

Acording to this info:
The 02 00 FB 04 part is:
02, ucVoltageType= MVDDC // To tell which voltage to set up
00, ucVoltageMode= ATOM_SET_VOLTAGE // Indicate action: Set voltage level
FB 04, usVoltageLeve so the voltage to set 1.275v. // real voltage level in unit of mv
So changing the FB 04 to 14 05 you could get 1.3v.
I have tested to change the vddci voltage to a 580 like this and seems o work: https://www.overclock.net/forum/27791442-post980.html
Damn, thank you for your thorough assistance, I almost feel guilty now, because I found someone who will switch his Vega 56 with my Fury X (+ some cash), so I wont be tinkering with Fury X BIOS anymore... I loved the tinkering, tighter timings for HBM, etc, but my Fury X was just bottlenecking me in some specific games, no mater how far I oc'ed or tweaked.
It has surprised how good the 4 GB VRAM still holds up. The Fury X can still play most games on megaultraextremedeluxe settings, with maybe textures and shadows set to high (which still give detailed textures not to scoff at). I will definitely miss the watercooler. It was so quiet, kept the card very, very
cool, far below its max without becoming very loud (around 45/50 Celsius with the temp target set to those values in the BIOS (I altered between 45 and 50 often whenever I did a modification to the BIOS) and a slight increase in the aggressiveness with which the fan changed speed to maintain that target. Pumping the heat directly out of the case instead of pumping it into the case was definitely a very big plus as well. I have already installed an extra 140mm exhaust fan in the top back of my case in preparation for the Gigabyte Vega 56 OC
I have four 140mm as intake, 3 in the front, one on the bottom, and I had one 140mm exhaust at the back, which was plenty to just cool my Ryzen 2600 with a Noctua NH-D15, and provided good airflow over the board/board-VRMs as well. A ~300W card dumping its heat into the case will be a nice 'stresstest' to test my overall airflow, but the extra exhaust will probably not hurt.
Anyway, thanks again for going through the effort to help me.
