It is not a secret that the default firmware and even settings for many of the ASIC miners that come out from the manufacturers are hardly with the best/optimal settings and often they are also limited in what you can tweak yourself. So some more advanced users take the matter in their hands in order to further optimize for performance and or stability and reliability and even add extra features that help owners of the devices to get better profit or higher profit for example. One such case is the Antminer D3 Blissz Modified Firmware for the X11 ASICs being produces by Bitmain that you might want to give a try if you have even at least one of these ASIC miners.
The custom firmware promises up to 20% lower power usage and some extra features such as ASIC voltage settings per chain as well as the ability to overclock or underclock per chain as well as more control on fan operational speeds. There are some usability improvements in the interface to make it easier and clear to use as well as some slight performance improvements as well to make it more stable and reliable in terms of operation including cgminer binary optimizations.
Do note that this is an experimental custom firmware and using it might void your warranty. Also note that it comes with built-in 1.5% developer fee built-in, so do have that in mind, although the improvements if working as promised are well worth the dev fee. The good thing is that even if you don’t like something or it does not work as expected flashing back the original firmware is as easy as installing the custom one, so you can quickly give it a go and if you don’t like the results to get back to the original.

Here is a ccMiner fork based on alexis78 code, but with added support for the KeccakC algorightm (source) used for CreativeCoin (CREA) mining. KeccakC is a slightly different variation of the Keccak algorithm, but it still requires modified miner to support it, so you still need to use a compatible miner for coins like CREA that use it. If you are looking for an sgminer with KeccakC support check this Windows binary from the official project website (source).
We have compiled a 32-bit Windows binary of the ccMiner frok from cornz with KeccakC support as it was requested by readers and you can download and try it from the link below. It is compiled with Visual Studio 2013 and CUDA 7.5, the supported Nvidia GPUs are Maxwell or Pascal-based ones (Compute 5.0 or newer). The performance we are seeing is similar to that of the original Keccak algorithm, so you can expect to see similar performance if you have mined a Keccak-based coin recently. Again, have in mind that Keccak and KeccakC although similar are not compatible with each other and you need to use the respective algorithm for the coins that use it!

The Xevan algorithm used by BitSend (BSD) has finally recieved a GPU miner for Nvidia-based mining rigs with the ccMiner fork by krnlx (source). Unfortunately for the moment the code of the miner only compiled and works under Linux, though hopefully soon things will be ironed out and a Windows version will also be available. For a Xevan AMD GPU miner check this older fork of sgminer available for both Windows and Linux OS with precompiled binaries. The Xevan algorithm is essentially a dual X17 with 128 bit headers, but it wasn’t that easy to implement apparently or there weren’t enough incentive up until now apparently.
The ccMiner fork from krnlx is reported to provide 3.3+ MHS on Nvidia GeForce GTX 1070 and around 6 MHS on Nvidia GeForce GTX 10880 Ti GPUs according to the author. Owners of Nvidia GeForce GTX 1060 mining rigs are advised to set the intensity manually in order to have the miner work properly with their hardware, GTX 1070 and GTX 1080 Ti should work fine with the default intensity of 20. If you are interested in how the Windows version is coming, then you might want to check out the official thread about the miner on Bitcointalk.
Update: Windows binary is now available thanks to Palgin, you can download a 32-bit Windows binary, VS 2013, CUDA 8.0 here.
