I know the benefits of undervolting Vega. I Had a blower style vega 56 card flashed to 64 once, undervolting that card was no problems to get more performance. Ever since i got this card its been a odd experience. from trying -25mv to -100 mv undervolt with an 2-4% overclock, my card is stable clock wise but i cant even overclock the hbm above stock or it results in crash or below 97% (while doing 3d mark stress tests). Also would result in green flickering artifacts in tomb raider demo. Also leads to llower firestrike scores. i just resulted to leaving the voltages alone, which allows me to put hbm at 1000mhz (havent tried higher) and overclock at 3% (currently) with no issues as i can notice. (firestrike score being around 23000-24000) I wonder if im doing something wrong or should i rma the card.
