New cpuminer Fork for Gridseed ASICs with Hashrate Reporting and Other Useful Features 22 Apr

2014

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.
