@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.
