Hello. I'm trying to mine wmc coin with lolminer 0.9.7 on frostypool.com with 6x RX480 ethereum custom bios.
five cards are working perfect and are hashing with 0.6 g/s but the first card (in miner card #0) is not working. It is not hashing and the hashrate is 0.00. I tried to disconnect all other cards and lived in the miner only the first card but it's hashrate is still 0

Can anyone please help me to solve this problem?
The first card is AMD RX480 8GB Sapphire Nitro+ with Samsung memory. The system is windows 10 and amd blockchain driver.
