Rig is giving me fits.

Constant, constant troubleshooting.  Can't get anything stable.  Rig will run fine for hours and then shutdown.  When trying to restart, Claymore miner will get to the OpenCL Pool/Solo and crash and burn before generating the DAGs.  I isolated the trouble card by using -di 0.  So it's failing on GPU0 when trying to initialize.  I took all risers out of the mix and plugged card straight into PCI slot.  Card shows up in device manager, appears working fine, and just wont initialize in the miner.  I flashed back to original bios and still no joy.  Sensors look okay in GPUZ.  Do I have a brick?

2100 MHz is a very high memory clock for a RX 570 4GB card. Try lowering it to 2000 MHz or 1950 MHz.

Flashed back to original clock settings and still not working.

Don't hard code the clocks in the Bios if you don't know what you're doing. You only need to adjust the memory timings in the Bios. You can try the Polaris Bios Editor 'One Click Timing Patch' bundled performance timings on the original Bios after you back it up.

With a modded Bios on the RX 570 you also need to run the pixel patcher after you update or install the drivers to bypass the Bios signature check or the card will have a Code 43 error in the Windows Device Manager.

After flashing the Bios, start over by running DDU in safe mode to uninstall the drivers, install the latest AMD Adrenaline drivers, run the pixel patcher, set compute mode in AMD settings, reboot and set the core/memory clocks for the card in the Claymore .bat or config file with:

-cclock 1150
-mclock 2000
-powlim -5
-cvddc 950
-mvddc 950

Or simply format the disc and start all over again.. This has fixed many of my problems
