Current version (14.1) doesn't work!
Please update your version of Claymore Miner to latest available version!

Finally Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v14.1 (Windows/Linux) has been released

v14.1 Beta:

- "strap" option: added support for Vega cards, up to 15% speedup compared to stock BIOS. Use "-strap 1" ... "-strap 5" values and overclock memory to find the best hashrate.

- improved compatibility with AMD 18.x drivers.

- now miner uses CUDA10 runtime library for Nvidia.

- a few minor bug fixes and improvements.

This version uses straps that were provided by Eliovp, they must be very good.

I spent much time in attempts to implement this trick, not in overclocking. Anyway, use WattMan or AfterBurner for overclocking. Put hdmi dummy plug into card and it will apply new clocks immediately. Or set new clock and disable GPU in the miner ("0" key for first GPU, "1" for second GPU, etc) and wait until memory clock will go idle (in a few seconds), then enable GPU again in the miner, new clock will be applied after that.

Except Claymore Miner, currently there is no software (at least public) that can apply entire straps on the fly.
