Bios Mod for ZCash Needed

[IamRune]

Does anyone have a rx 480 Bios mod for the 8GB cards?
I'm currently using Boysies low wattage usage on 12 of my cards ( 6x Sapphire Nitro +, (3) MSI and (3) Power Coolers. )

Averaging between both Rigs 850/HS each for total of 1.6 K/H.  Each card is averaging between 130-150

I've seen other people getting up to 160/S per card.

Any help would be appreciated.  Thank you!

Thank you.  I tried experimenting with different overclocking settings and was able to get 162 Sols per card average!
