cpuminer-gridseed-new-tui

Sandor111 has released an updated version of his cpuminer fork adding a TUI (Text User Interface) containing the most important information that you would need to know for your Gridseed ASIC miners in an easy to read format (source here). Another new useful feature in the latest release is the autodetection of the number of chips, so no need to set it manually via the command line anymore. We have a windows binary available for you, and we do recommend to give it a try if you were sticking to cgminer because of the TUI available there, especially now that cpuminer also has one. If you want you can still download the previous cpuminer for Gridseed with no TUI, we’ll have it available for people that prefer to use that, and below you can download the new TUI version for windows.

cpuminer-gc3355-win32-sandor111

Gridseed ASIC users will be happy to learn that there is a new fork of the cpuminer software with support for Gridseed ASIC miners (for Scrypt only mining) thanks sandor111 over at the Bitcointalk forum. He has added support for local hashrate reporting which was one of the key missing features of the previous builds, but he did not stop at that, he has also added support for per chip frequency autotuning (automatic overclock until the best frequency is reached for each chip) and the ability to manually set frequency for each miner by using a single instance for multiple devices. There is also support for the new Gridseed G-Blade miner, you only need to set the number of chips to 40 for each of the PCBs of the Blade Miner in order for the local hashrate to be properly reported.

We have compiled a windows binary of the new miner and you can find the source here. Great work and essentially what the original cpuminer should’ve been from the start, and now it is finally here, simple and easy with all the right features available. We are currently testing the new miner, especially the autotune feature, so far it seems to work quite well, but be aware that it could take some time for the miner to adjust frequencies, so make sure you set a starting frequency that is closer to what you expect that the device should be capable of. For example 850 MHz for default non modified 5-chip ASIC, 950 MHz or 1150 MHz if you have dome some sort of a voltmod already. Do check the included Readme file for a description of the options and some examples as well as for a simple, but effective Batch script for using backup pools with the miner. If you find some problem or an issue using the miner please do report it, so that it can be addressed.

ccminer-latest-build-groestlcoin-optimizations

The ccMiner software miner for Nvidia GPUs has received an update of the source code adding some improvements for the Groestlcoin (GRS) miners that brings a nice performance increase. We have built a windows binary based on the latest source as it is not available as an official release yet and have tried it to see what is the boost in terms of hashrate you could expect to get. On an Nvidia GeForce GTX 780 Ti GPU we have managed to get from about 7500 KHS to about 9000 KHS with the latest code, so definitely a nice improvement if you are mining GRS.

Do note that the windows binary you can download below is compiled for Computer 3.5 cards, so it might not work on older cards. It is also compiled with Visual Studio 2012, so if you do not have Visual C++ Redistributable for Visual Studio 2012 you will have to download and install it. If you want to compile the miner from the latest source code yourself you can take a look at our guide for compiling CudaMiner as it will work out just fine for compiling ccMiner as well.
