what cooling you have for rig, what is the temperature core and HBM of the cards, and RPM?
Air cooling /open rig/ , 55 core temperature and 65 HBM temperature of the cards, and vga fan - auto /~3500 RPM/
txs. That explain everything.
My rig are in small space, running hotter with 66 core temp. and over 77 HBM temp. For now i testing rig with lowering clocks and more mV.
Here is 2 Vega 56 and one Vega Strix 64. Strix is better cooled and work without problems:
GPU0 : 1877 H/s [T: 63c, RPM: 3577, CC: 1407 MHz, MC: 1050 MHz][BUS:3] - "more problematic Vega 56"
GPU3 : 1940 H/s [T: 66c, RPM: 3516, CC: 1407 MHz, MC: 1095 MHz][BUS:14] - "other Vega 56"
GPU2 : 2029 H/s [T: 56c, RPM: 3473, CC: 1442 MHz, MC: 1100 MHz][BUS:11] - Vega 64 Strix
