Claymore, I'm encountered problems with Win 10 1803 and 18.4.1 drivers. My 1st GPU (active - monitor connected) drops hashrate to 0 after several minites (sometimes even less minute) after start. Sometimes hasrate rises than drops again, sometimes drops until restart miner. 2nd card (inactive - nothing connected) works normal. Use modded bios and setting OC and voltages in your miner. RX 580 8Gb cards.

Maybe it's need to add something in miner to compatibilty with new drivers? 1803 and old 18.3.4 driver works normal. But I'm afraid that it will be on all new drivers too...
