Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.4 (Windows/Linux)

Do not use Crossfire for mining, disable it.
Set the core clock to 1200MHz or lower (just enough to not affect your hashrate by a significant amount), as well as the voltage, and the memory clock as high as you can without getting any GPU Memory errors in HWinfo.
Look into BIOS modding as well, only through that will you have a shot at getting 30MH/s.

I did some bios modding and tuning is msiAB last day. HWinfo was running and showed 0 errors, but I saw glitches on the screen, and after a few mins my system froze. Tried multiple times with multiple variations but no errors in HWinfo, just glitches and crashes.
I did find the almost optimal settings, but HWinfo did not help me.
I think I missed something. Can you help me pls?

What exactly did you tune? What's your memory vendor?
Try copying the 1750MHz strap to 2000MHz if you have Micron or Samsung.

I have an asus rx 470 strix 8g oc micron memory card. BIOS (modded marked with red): https://www.dropbox.com/s/dy8b7q27y8xx3e3/bios-1110-2000.jpg?dl=0
In afterburner I set -60 mV, +50% power, 1110 core clock, 2000 mem clock.
I did look good, and mining ETH only it worked at least 20 mins, but dual ETH+DCR glitches came, than crash, but HWinfo showed nothing.
