Yet another update from sp on his open source and free fork of supminer (ccminer) called Raven x16r/x16s Spmod-git #7 (source) with a bit more extra performance thanks to optimizations done to hamsi/Echo/echo-simd. The X16S support should be fixed in this release as well as it was broken in the previous, but our quick tests in a few pools show that no shares are being accepted – low difficulty or invalid shares getting reported by the pools, so it may need some more work. X16S support is now really fixed, make sure you download the miner again if you have downloaded the initial binary that was released for the fix applied.

The ultimate goal of this miner is apparently to take the top spot in terms of X16x performance from the current leader z-enemy 1.15a and this release is a step closer to that goal. Our tests on GTX 1080 Ti show that Raven x16r/x16s Spmod-git #7 is still a tiny bit behind in terms of pure performance, however you should not forget that the z-enemy miner contains a 1% developer fee built-in and that already makes things pretty much even on actual performance. It is always good to have some competition as it drives things forward.

Another update from sp on his open source and free fork of supminer (ccminer) called Raven x16r/x16s Spmod-git #6 (source) that promises another +10-15% performance increase (Optimizations to aes, echo and simd) over the recently released Raven x16r/x16s Spmod-git #5. The only not so good thing is that this miner comes at a time when X16R mining is not very profitable to be mined, but that goes for many other algorithms as well in the currently low profit period for mining. The Github repository only has an official Windows binary, 32-bit CUDA 9.2, so if you need something else you would need to compile from source yourself.

With the latest Raven x16r/x16s Spmod-git #6 the miner is trying to compete for the top spot performance wise with the other fastest X16R miners out there (X16S support seems to be broken). Performance wise the spmod-git #6 seems to be slightly faster than T-Rex and z-enemy 1.14, but could be just a bit slower (in some of the algorithms) behind the latest z-enemy 1.15a. However you should not forget that the z-enemy miner is a closed source one and comes with a built-in 1% developer fee, while the Raven x16r/x16s Spmod-git #6 miner is free, open source and with no dev fee so taking that into account the end result in terms of hashrate you get maybe is already pretty much the same.

It has been a while since sp has released open source and free code for a faster miner, but better late than never. The latest Raven x16r/x16s Spmod-git #5 (source) promises 10% increase in performance over the previous release for X16R and X16S algorithms thanks to numerous optimizations to the used algorithms like echo, shabal, simd, sha512, fugue, shavite, groestl and skein. The latest version also has added support for higher intensity values, so you can experiment with that to maybe squeeze some additional performance. The Github repository only has an official Windows binary, 32-bit CUDA 9.2, so if you need something else you would need to compile from source yourself.

Comparing the performance of the new Raven x16r/x16s Spmod-git #5 miner to the recently released z-enemy 1.14 miner it is still a bit slower. Maybe it is on par with the previous release 1.12 of z-enemy in terms of hashrate, however you should not forget that the z-enemy miner is a closed source one and comes with a built-in 1% developer fee, while, surprisingly, the Raven x16r/x16s Spmod-git #5 miner is free, open source and with no dev fee.
