The development of some of the ccMiner forks for Nvidia GPU miners didn’t seem very active visually in the last couple of months, especially with coins such as ZCash (ZEC) that came with their own miner releases, but it hasn’t been stopped. A few days ago tpruvot has made a pre-release version of his new ccMiner 2.0 available (source) for people interested in checking it out with probably a few small things left to be ironed out before the final 2.0 release is made available. So if you are using Nvidia GPUs to mine crypto coins then you might want to give it a try and don’t forget to send a tip to your local friendly ccMiner developer for a beer or two to show your support.

ccMiner 2.0 RC2 changelog:
– Handle cryptonight, wildkeccak and cryptonight-lite
– Add a series of new algorithms: timetravel, bastion, hmq1725, sha256t
– Import lyra2z from djm34 work…
– Rework the common skein512 (used in most algos except skein ;)
– Upgrade whirlpool algo with alexis version (2x faster)
– Store the share diff of second nonce(s) in most algos
– Hardware monitoring thread to get more accurate power readings
– Small changes for the quiet mode & max-log-rate to reduce logs noise
– Blake2s fix, variant built with CUDA 6.5 (not usable for lbry)

Do note that this release may not contain the best optimizations and fastest performance on all of the supported algorithms, so depending on what you are currently mining you may need to stick to another faster fork of ccMiner or not. Also the CUDA 6.5 binary release does not work for LBRY mining as noted in the changelog, so either use the 8.0 release or compile with 7.5 for mining that coin.

cpuminer-opt-3-3-8

Another update in the form of a Windows binary compiled from the latest cpuminer-opt (source) CPU miner with added optimizations for many algorithms using the AES-NI instruction set (also works on older SSE2 capable CPUs). Up until recently the cpuminer-opt was available only for Linux users, but starting from version 3.3 there is also Windows support and we have compiled 64-bit binaries of the miner for Windows for the latest released version 3.3.8. The latest update brings some performance improvements such as blake2s with about 10% higher hashrate, support for new algorithms such as LBRY, Whirlpool and WhirlpoolX as well as fixed Skein2 that was apparently broken in the previous version.

In the archive below you can find multiple executable files that are compiled for different CPU architectures that support AES-NI instructions, so you are welcome to try them to see what works best for you. If your processor does not support AES-NI (CPUS introduced 5 or more years ago), then you might want to use the cpuminer-sse2.exe binary. The default cpuminer.exe is compiled for Intel Westmere, the first Intel architecture that has support for the AES-NI instruction set and cpuminer-amd.exe is bdver1 which should work on all AMD processors with AES-NI support. If you have a more recent Intel Sandybridge, Ivybridge, Haswell or Broadwell-based processor you can try the respective binary to see if that will squeeze some extra performance, or you can compile directly on your PC with the native instruction set supported by your CPU.

cpuminer-opt-3-3-7-windows

Here comes a cpuminer-opt Windows binary compiled from the latest (source) of the CPU miner with added optimizations for many algorithms using the AES-NI instruction set, though the miner also works on older SSE2 capable CPUs with lower performance. Up until recently the cpuminer-opt was available only for Linux users, but starting from version 3.3 there is also Windows support and we have compiled 64-bit binaries of the miner for Windows for the latest released version 3.3.7. The latest update brings some performance improvements such as the Lyra2 now being AES optimized and having +7% higher performance, a small increase of about 1% in most chained algorithms (X11, Quark, Lyra2v2, etc) and some fixes such as Lyra2v2 now being properly reported as AES optimized.
