XMR-STAK 2.7.1 (CN-Heavy optimisations / Auto-tune / Bittube fix)

[RyoCurrency]

New version of xmr-stak 2.7.1 is available for download.

This update brings you following:
- Bittube fix(over 2.7.0 version)
- Auto-tune function of intensity. When enabled - miner will try different intensities and lock on the best performing. The step of adjustment is configurable.
- Adjustable interleaving function (suitable for dual-threaded configs).
- Added "strided_index" value - 3.
- Optimizations for AMD GPU-s (up to +15% in hashrate in CN-heavy compared with previous version ).
- Optimizations for NVIDIA GPU-s.
- Auto-generated config for AMD Vega is now dual-threaded.
- bugfixes.

Updated miner docs: Github

Sharing is caring!

Help other miners, or request help: share your miner GPU config + overclock parameters + memory type + driver version + OS in this thread and post resulted hashrate.

Can this parameter be used on version 2.7.0 ?

[RyoCurrency]

Can this parameter be used on version 2.7.0 ?

which one exactly? it is a list of configs as example. when you run first time stak, it generates config based on your system itself. then if you feel your gpus can do more, you need to slightly fine tune it.
