What operating system? Drivers version? What are the full launch options?

Hmmm, it's strange... Try to launch mining only on that last GPU.
Need to try other miner to exclude miner bug.

You set it manually? Or make autotune?

Make autotune for -gt parameter.

Yes it will use more electricity and it will run hotter. How the ETH algo works its mostly limited by the memory speed. So most of the time the GPU is not doing much since its waiting for the memory to complete its job. By changing the memory straps the memory runs faster and is able to provide the GPU compute the data to analyse quicker, so your speed increases from like 23MH/s to 30MH/s (if RX 570). Since the GPU uses more resources it uses more power and hence runs hotter.

This is actually why it was possible to dual-mine with ETH, because the GPU didn't do much most of the time and it was possible to mine at full ETH speeds while also dual mining other coins like DCR or SIA or PASC.

Use driver version 375.57, it is only 250mb, very first driver for 1050/ti i think. Works for me, if this stops working, only solution is to not use WIN10.

I've figured it out.

And claymore should have give clear instructions in the readme.

1. run cmd with admin rights
2. cd to the ethminer folder and run:  eth..64.exe -driver install
3. restart
4. overclock your AMD cards as usual.
5. now add -strap to your start.bat and everything will be ok.

Nothing has changed for me. It's the same hashrate (29.3) as 12.0 on blockchange driver and a modded bios.

For vega, proper PPT needed...
