You need to use the AMD blockchain drivers or the latest Adrenaline drivers and switch to Compute mode from Graphics mode in AMD settings. That will apply the AMD epoch Dag size fix and give you the hash rate you had before the Dag got over 2GB.

Dag Epoch effected to Polaris cards, so do this:
You could try to modifications your bios cards for the best Polaris cards performance. Polaris bios mod do by almost every miner. But if you are happy enough with stock bios, it's okay.
When the time initialize the awesome miner. Initially in the prompt page I find the message saying 4xx crimson polaris is recommended. Since I am newbie to the mining field. I am not sure what bios modification you are mentioning here. Please elaborate me bro.
this day, your 470 4 GB can reach almost around 27-29 MH/s on Ethash with modded bios. globally bios modification mean replace original conditions of your bios cards. we would change a few thing on it such as timing strap, voltage etc.
a simple way to do it :
1. you need to download Atiflash, Polaris bios editor, Pixel clock patcher (atikmdag patcher).
2. Save your original bios using Atiflash, duplicate it, one as your backup if something bad happened. and another one you would modification it on Polaris bios editor.
3. Open your Polaris Bios Editor (PBE), I suggest using Version 1.6.2 or above with one click modification (since you didn't have much experience on it).
4. Save your Modded bios and then flash it using Atiflash to your cards.
5. Use atikmdag patcher for handling bios signature, So the system would recognize your device.
