Hello everybody. I have a Sapphire RX 580 4Gb, with modded BIOS (including memory timings) and overclocked until instability (1050/2020). It run under windows 10 with mining drivers, and Im having arround 25,5 Mh/s. I tried a lot of things trying to reach the "oficial" 30Mh/s that these cards are supposed to make. I even change my card for another one, but the hashes remain the same. After reading the experiences of several people with my same card and same hashes, i realized that 25 Mh/s are pretty OK for this card.
Now im thinking about building a dedicated mining rig with six Sapphire RX 580, and i wonder if the 8Gb version will reach more easily these "oficial" 30Mh/s
Thank you very much in advance for your help.
My Sapphire Nitro RX 580 - 8 GB runs at 32 Mh/s. MSI RX 580 - 8 GB runs at 30Mh/s. I had some issues with getting them up as well in the beginning. It was due to a bug int my AMD drivers. I uninstalled them with DDU and installed the last blockchain drivers.
