Vega can do ~4000h/s cryptonight-lite.
I managed to compile xmr-stak-amd for it. Or you can find ready windows build on github with 1% fee.

For cryptonight 900+ mem speed can be enough but for eth you'll need 1100 and Vega64 bios
Nice!

So Aeon is even more profitable than Monero.
I am gonna try to compile the algo with stak too.
On another note...
i tried flashing my vegas 56 with the 64 bios and i am having troubles with the reg files for powerplay from @Hellae. None of them works.. windows wont boot / green screen and then fans starts to spin like crazy. Any suggestions what may be wrong?
I have it currently running without the undervolt which is pita (vdcc 1.1V). Its doing ~1700H/s per card.
My gfxs are Sapphire 56 (1.6Gbps) versions.
