Re: Ethash DAG epoch RX470/480/570/580 FIX !!

I just install the RX vega drivers on my RX 580 and it work as well. DAG issue back to normal.

Here is a link to the official AMD website http://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-Crimson-ReLive-Edition-for-Radeon-RX-Vega-Series-Release-Notes.aspx

I'm guessing your RX570 is a 4GB?

As I wrote above, I tested it on a 470 8GB and did not change its hashrate.

They Are 8 RX 580 8GB I'm overcloking using bios. I did try to overclock the memory and core using afterburner beta 4.4.015 as well as undervolt for one of my card and it took the new settings.
I have my monitor connected to a GTX 1070 and use it as my main card for the monitor.

Update afterburner 4.4.015 took the new under volt settings but it goes up and down. So I will stick to making the changes on my bios instead .

Mate I just tried this on a 7x 570 4GB rig and the DAG issue is still there, as in, my cards don't hash any faster than before...

When you update the drivers you also have to verify that your overclock settings are correct since this driver will change your setting to the card default. I change my default memory , core and voltage on the bios level that way I don't have to deal with any 3rd party applications. There is many tools in this forum to help you play with your bios like the polaris bios editor.
