Best OC for RX 580 4GB sapphire

hell guys , i want to ask about the best overclock for ERGO using sapphire nitro+
i’m getting 58Mh only , while guys have up to 65mh !


set higher core clock. memory clock set to about 1800

Is your card Bios modded? I think most them guys getting 65mh/s have bios modded cards that they fine tuned. Since most my RX series cards have dual bios I can try and mod one bios on them and expirement a little bit. My RX 470 and RX480 are getting around 52MH/s currently.
