my stock amd rx 480's has 235 s/h. How can i overclock them for better perfomance? i have tried 1300core and 2100 mem clock speed, but they starts to hash even lower~206 s/h. Pls give me an advise how can i solve this problem.ty.
that is a decent number.
the only way to do better is a bios flash
and if you never did bios flashing be careful as you can brick the cards.
For me so far mining Zcash is better on stock bios plus you avoid the possibility to brick your cards, also flashing bios can lead to huge memory errors in long run, so anyways be careful at your place I'd leave the stock bios if you haven't messed with them yet.
Also as
philipma1957 said you have great performance on stock bios.
