1. add virtual memory, 16gb per card
2. Make sure you use 23aug blockchain driver
2. re-enable both cards in device manager before mining
3. use cast-xmr miner
4. make sure your temps are below 70 degrees (both gpu and hbcc)
If I have 8 Vega 64 cards how to proceed all 8 cards? Looks like only 7 works.
