I made a little comparison between Bminer 5.4.0 and DSTM 0.6 (24h for both) on my GTX1080+GTX970 (MSI Gaming)...
The results is:
In the miners console my speed are:
- In Bminer: for GTX1080 - 600Sol, for GTX970 - 350Sol (950sol for both)
- In DSTM:  for GTX1080 - 580Sol, for GTX970 - 340Sol (920sol for both)
But my pool (Viabtc) report that hashrate after 24h is: 890-900sol for DSTM (as it should be with 2% devfee and 0.5% rejected shares) and only 850-860 for Bminer (with nofee or with) -10%!!!
And with bminer I have a little more rejected shares (1.2% vs 0.5% on DSTM).
On the bminer side is more stable work (with DSTM I need to reduce a little my VGAs clocks). In my opinion - bminer is a good and stable miner but in final result on the pool it is not as fast as it report in console, or it work for someone else more often than it should be and without my permission?...
Conclusion: for now I will stay with DSTM, but keep waiting for a new version of Bminer with more stable and honest hashrate, because I like this miner for its stable work. Good luck Reallbminer and don't give up!
