Another update fork ccminer from spmod with support for X16R / X16S algorithms for mining Raven (#8 source code). The new version increases the performance for X16R and X16S by 5-7% regarding the previous version of the miner. Spmod got an excellent competitive solution, especially given open source, although the z-enemy 1.16, released a few days ago, seems still a little faster.
For maximum performance when using this miner, you need to overclock the GPU memory by 500 MHz or more (depending on the model of your GPU), as well as use a fixed shares difficulty. To set a shares difficulty parameter, you need to calculate half of your hashing speed. For example, if your hash is 100 MHS, you should write "-p d = 50" in the .bat file before running the mining process. It was also promised that soon there will be a new version of the fork for Raven (RVN), which will solve the problem with complexity.
