I'm having black screen crashes on my new Vega 56 card. I initially thought it was my power supply giving out but after replacing that I'm still encountering this. This occurs when there's no load on the card (ie Idling while I'm not home). I'm currently following the suggestions as per RX Vega64 Liquid -- Possible HBM2 Downclocking / Upclocking / Black-Screen issue but I'm wondering if there has been any new developments in remedying this, or should I look at RMA-ing my card.
