I still don't know how you were able to get that low. I'm always around 10 incorrect per 1000 no matter how much I underclocked. Tried different ram timings, drivers, voltages etc. Moot point now that keccak is dead.
try 11.0 and save the hassle.
his oc is too weak and voltage is too high, maybe the reason for his low incorrect shares. but still he has. rx580 could do much better than his inputs.
anyway, mine is enjoying 0 incorrect shares now using 11.0, better hashrate and effective hashrate. and finally, i can sleep without worrying about it.
i dont know what is up with the latest version and previous versions after 11.0.
