Why Sapphire Nitro cannot reach 30mh/s..

[almirfiorio]

Dear Friends

At about 2 months I downloaded the anorak.tech bios for the sapphire rx 480 Nitro (Not Nitro +) card with the elpida memory 
and was working perfectly at 1150x2150 with 30 mh / s.

From a time to here I can not get past the 28.5m / s

Can someone tell me how to solve this?

Thanks
Almir

This is due to the increasing DAG size/DAG bug with AMD drivers. It is a known issue that Claymore is working on, but it is also because ETH is simply getting harder to mine. This will continue to get slower and slowed until either the bug is fixed and or the difficulty drops a lot. From my understanding it is sort of a dual bug and feature from two different parties. You can confirm this by mining another Ethash based coin and watching your mining rate go up a lot.

The Vga card cannot reach 2150, the maxximum value is 2050
But I could before
When I put 2100 it already hangs

Can tell me how to solve this?
