go install AMD DRIVER ver 20.4.2
after update my AMD Driver using 20.4.2, i've still having problem like before..
- 5 GPu work only 4
- RX480 just get 9mhs
- after a few minutes miner shows error: Allocating buffers failed with clCreatedBuffers (-61) and stop

my problem never solved..
sad mode: ON
1st make sure just run only 1 RX card. DDU the driver on safe mode then install 1card RX then install 20.11.1 driver. after turn compute mode on. after make your settings and OC setting using amd wattman or overdriventool. look what you get with 1 card if it is hashing normal then keep adding your cards back. is it bios modded cards?
