I have two rigs: 8xVega64 and 4xVega56, both dig CNv7 with weeks of stable uptime. I interrupt it only for miner updates. I guess running GPU-Z makes problems, not the miner itself.
np.
my 6*vega56 nitro+ GPUz not work with any version srbminer(i not try with cast or xmrstack). i try HWinfo but not work with srbminer. when i start gpuz+miner = BLOCK.
gpuz and hwinfo work fine solo.
3*vega56 powercolor gpuz work finwe with all version srbminer
