Hi! I have an ATI RX 580 with Hynix GDDR5 memory. Im using it with Raveos to mine ETH and is losing about 25% of its shares. It worked fine for the first few days. I use a moded Bios and this setting:
Core Clock 1050
Memory Clock 1950
Core Volt 950
Memory Volt 950
Fan 50%
The current hashrate is 29 mhs and the temp is 57°. This is the exact model i have: https://www.sapphiretech.com/en/consumer/pulse-rx-580-8g-g5

Any ideas? I read about invalid shares and tried to lower the clocks (kind of randomly) with no success. Im kind of new so im learning about this stuff.
