Hi guys, Im new to mining and new here but Im hoping you can help me. I finally got a GPU after a couple weeks of constantly refreshing on Amazon and Im just trying to get better performance.

GPU: XFX RX 570 8GB w/Hynix memory plugged directly into the MOBO (ASUS Z270H), Win 10, EVGA 750W Gold PSU, 8GB RAM, AMD Crimson Beta for Blockchain and MSI Afterburner.

Before trying to mod anything, I joined Nanopool using Claymore to mine ETH only and was getting 16 Mh/s so I flipped the ‘dual bios’ switch (pushed towards the front of the card with the output connectors) but it still gave me 16 Mh/s. I then got Polaris, edited the memory timing lines and copied the lines from 1:1750 and 2:1750 to 1:2000 and 2:2000 respectively, flashed the new bios but it wouldn’t mine saying it couldn’t find a GPU. I didn’t get ATI pixel clock patcher at this point. I got the Polaris mod for RX5xxx and saw it only had the memory timing lines copied from 2:1750 to 2:2000 but I flashed the bios and it worked, giving me 26 Mh/s.

I decided to check my power consumption after 4 hours or so and it was 200 watts when mining. My computer peaked at 50 watts but seemed to stabilized around 25 watts idle. I shut down the computer, flipped the ‘dual bios’ switch again but it seems like the bios flash is on both switches because it was pulling 200 watts and 26 Mh/s even though I only flashed it when it was flipped in the forward position.

I played around with a few of the MSI AB settings as I’ve seen many people suggest but everything stayed about the same.

Any ideas on how I can get my power consumption down as I thought I should be able to get a higher hash rate with less power (~29 Mh/s @ ~130watts).
