Hello !
I have a problem with my rig (8 x RX VEGA 56) and SRB Miner on cryptonight v8.
Try this pools config :
{
"pools" :
[
{"pool" : "stratum+tcp://cryptonightv8.eu.nicehash.com:3367", "nicehash" : true, "wallet" : "36GWXKPs3fp2RWbB2qc7fREss653c6o5nL.D31", "password" : "x"},
{"pool" : "stratum+tcp://cryptonightv8.usa.nicehash.com:3367", "nicehash" : true, "wallet" : "36GWXKPs3fp2RWbB2qc7fREss653c6o5nL.D31", "password" : "x"},
{"pool" : "stratum+tcp://cryptonightv8.jp.nicehash.com:3367", "nicehash" : true, "wallet" : "36GWXKPs3fp2RWbB2qc7fREss653c6o5nL.D31", "password" : "x"}
]
}
