Well to be honest there are always risks in everything, but I am an honest person. I have sent the mod to everyone that has sent me the payment.

I have only had 1 customer not be able to reach the specified speed and we worked out an agreement for a partial refund, as my mod DID provide a pretty decent performance increase for him.

That being said, I think you will be happy.

Hey Guys!

I have figured out how to kick these cards into high gear.

RX 560 4gb Micron, Hynix,and Samsung (New)

16.2Mh/s ETH ~51W
15.9Mh/s ETH and 490Mh/s DCR (dual mining) ~62W
15.9Mh/s EXP ~50W
15.5Mh/s EXP and 470Mh/s DCR (dual mining) ~61W
16.1Mh/s ETC ~51W
15.9Mh/s ETC and 470Mh/s DCR (dual mining) ~60W

So far I have gone for several days stable with this build. It has crashed after 5 days.... but that is considered rock solid for most.

Sapphire RX 560 4gb micron yield the best results. Similar results will be had on all 4gb 560's though. 15+mh.

Price: 0.30 eth
(included modded bios, oc config and fan config, my personal support in helping get it setup)

email me here if interested: minerscott1986@gmail.com, I also have custom bios' for many other cards. RX 470/480/570/580 which yield ~29mh @ ~67w on GPU-Z. Those mods are also 0.30 eth each.

Thanks for respond
