Hello i really need help if someone know
i try to mine with 3 rx470 nitro + sapphire and was good it some samsung memory,
then i have add another rx470 nitro + sapphire (so the 4th and some problems arrive
like :
Error in server response
"id":1,"jsonrpc":"2.0","error":{"code":-1,"message":"Lowdifficultyshare"}}
or (( some invalid share on minergate) -0.1xmr balance and -0.1xmr two consecutives days )
when i disable this card hynix it was mining good in one pool (monero.miningpoolhub.com)
no json error low difficulty share
i have use gpuz to watch the card the 4th and i noticed it was Hynix and not Samsung
is it a problem of compatibily mining?
should i put this on in another computer for mining with her? or give back( but i will have to pay a bit the return and catch a good one samsung?)
