Hi!

I have asus rx 580 8gb cards and sapphire nitro+ rx 570 4gb cards.
The 580 cards working good, but the 570 cards dont start. When i start the miner, the gpu clock and the memory clock load are 100%, but after few seconds the memory clock reseted to default 300MHz. The gpu clock load dont change, it stay 100%. The hashrate is 0 (only the 570 cards) In this time the entire system is slowing down extremely.
What might be the problem? Any idea?

Details:
Win 10, Adrenalin 18.5.1.
jce_cn_gpu_miner64.exe --no-cpu --auto --any --forever --variation %FORK% --low -o %POOL%:%PORT% -u %WALLET% -p %PASSWORD% %SSL% %*

Thanks!
