Modded ethereum bios for zcash

[amd1361]

Hi

I am mining ethereum with my 5xsapphire rx470 the GPUs bios have been flashed for ethereum.
My question is that if I want to mine zcash now do I have to make any changes regarding the GPUs bios or clocks?
Thanks

Zcash does not profit from tweaked memory timings and high memory clock.
The most profit you get out of overclocking the core speed.

I would advise to use a default rom with default clock speeds, and try to minimize the core voltage of memory and core.
You wont have a boost in mining speed, but a better energy efficiency.
