@Eliovp I still wait your test with 2100 mhz - 1500 strap.
@All VDDC can easily drop with Msi Afterburner. Just edit your bios for gpu frequency, ram frequency and also for ram straps. TDP and VDDC can tune with Msi Afterburner.
Don't consider the idiots who drop the VDDC and give no information. They behave as if they are Mandrake.
1500 strap all the way up, frame buffer will drop, as so will hashrate.
I only have Samsung cards and a Micron card to test with, perhaps on hynix this will work, i can't say. Still, i doubt it

Btw, your pictures are unclear, like always. No clear info.
have you ever done anything for the community? Nope i don't think so. A lot of words. But nothing to show for.
Adding VDDC Offset will let the voltage controller start calculating the needed voltage for a specific DPM at a lower start. Therefor it is better to do it like this.
You have lots to learn young padowan :p
