Rx 570 sapphire nitro+ hynix bios mod issue!

[Pippuz96]

Hi everyone, I recently bought 4 rx570 sapphire nitro + oc 8 GB ram ( hynix ), I was trying to follow some guides in order to get 27/28 mh/s. Without any mod my cards they are running at 20mh/s and it doesn't seems normal to me.
When i tried to edit the bios using Polaris editor I didn't get any timing like 1:1750 or 2:2000 im only getting until 0:2000.
I'm using the latest AMD driver should I change it?
My cards they also have a physical bios switch button that also need for something?
Thanks in advance for all the helps or advice.

Make sure you are using the latest version of Polaris Bios Editor

You also need to use the AMD blockchain drivers when mining ETH and the pixel patcher to bypass the driver signature check.

I have a Sapphire Nitro+ RX 570 4GB card and using the PBE v1.62 'one click timing patch' Bios mod get ~29 MH/s with a 1150 MHz core clock and 2000 MHz memory overclock.

thanks for your help, i installed the beta blockchain drivers and mod the bios with the one timing patch and now my card are working around 24/25. My MSI Afterburner seems not working, i cant edit the mhz of ram and cpu any solutions?

You don't overclock the cpu and memory. You can overclock the GPU core clock and memory with Afterburner like it shows in the video. Make sure it's the latest version of Afterburner 4.4.0 beta 19. You can also adjust the power limit and unlock the voltage control in the settings to undevolt the card to use less power. I use a -96 mV core voltage and -15% power limit.

If it still doesen't work with the latest Afterburner, uninstall the drivers in safe mode using DDU like it shows in the video, reinstall the blockchain driver and run the pixel patcher once it's finished and reboot.

Guys what Mh/s do you get these days?

I've read that DAG size affects the calc speeds. Have you been affected by DAG 160?

My speed (overclocked and BIOS modded) is 25.3 Mh/s at the moment. I wonder wether I can get better out of the card :/

Thanks
