Hello! A few, maybe two weeks ago (I haven't been able to keep up with the time to fix this) my miner dropped its hashrate considerably from around 100Mh/s to 2.3Mh/s... At first I thought that could have been caused by a necessary driver update but I just did it and the problem remains the same. Then I uploaded the miner from 0.7.17 to 0.7.22 and tried with .21 aswell...

Does anybody could know what could be the problem I'm having? Thanks in advance.

My rig:
6 AMD RX570 4GB (one of them fails after some minutes mining, so I just use 5)
Radeon Software Adrenalin (Latest december 8th update)
Win 10 Pro x64
I use ethermine pool

set GPU_MAX_ALLOC_PERCENT=100
set GPU_SINGLE_ALLOC_PERCENT=100
set GPU_MAX_HEAP_SIZE=100
set GPU_USE_SYNC_OBJECTS=1
teamredminer.exe -a ethash -o stratum+tcp://us1.ethermine.org:4444 -u walletaddress.wname -p x --restart_gpus --uac --eth_alloc_epoch=374 --eth_4g_max_alloc=374 -d 1,2,3,4,5

I tried adding --enable_compute aswell...
