Custom Bios RX 580 4GB OC Elipida memory

[CryptoSquad]

Hi

Can anyone help with a custom bios for the RX 580 OC With Elipida memory?  Happy to pay for a good one.

Currently i have copied the 1500 timings to 1750 and 2000 and i am getting about 24MH's. Overclocking as much as i can (1100/2000) gives me about 25.7 MH's.

I was under the impression i should be able to get more out of this card? 

Any advice appreciated.

Thanks!
