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

22, Apr 2014

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.

Updated cgminer 3.7.2 and cpuminer for Overclocking Gridseed 5-chip GC3355 ASICs

1, Apr 2014

cgminer-updated-version-for-overclocking

We have updated our windows builds of the cgminer 3.7.2 and cpuminer for Gridseed 5-chip GC3355 ASICs and you can download them below. Both versions include the latest official releases (cgminer source and cpuminer source) and in the source folder you can find our modified files for adding additional frequencies for overclocking if you want to compile from the source code yourself.

Both the cgminer 3.7.2 and cpuminer with Gridseed 5-chip GC3355 ASIC support the following frequencies that you can set to find what works best for overclocking the devices you have:

250, 400, 450, 500, 550, 600, 650, 700, 706, 713, 719, 725, 731, 738, 744, 750, 756, 763, 769, 775, 781, 788, 794, 800, 813, 825, 838, 850, 863, 875, 888, 900, 913, 925, 938, 950, 963, 975, 988, 1000, 1013, 1025, 1038, 1050, 1063, 1075, 1088, 1100, 1113, 1125, 1138, 1150, 1163, 1175, 1188, 1200, 1213, 1225, 1238, 1250, 1263, 1275, 1288, 1300, 1313, 1325, 1338, 1350, 1363, 1375, 1388, 1400.

Download cpuminer OC Edition for Gridseed 5-chip GC3355 ASICs

cpuminer-gc3355-win32-fixed-oc-edition

A few days ago we have published a version compiled for windows of the cpuminer for the 5-chip Gridseed ASICs that fixed the power consumption when using the devices for Scrypt mining only (6-8W power consumption). This version has allowed the user to set the operating frequency of the chips inside up to 900 MHz and our unit seem to work best at 850 MHz as at 900 MHz is seems to have more HW errors. That however did not stop us from modifying the cpuminer to allow for even higher operating frequencies of the Gridchip GC3355 processors, so now we release an OC Edition of the cpuminer that will allow you to go all the way up to 1200 MHz operating frequency.

The OVERCLOCK EDITION we have made allows you to go for higher operating frequency above 900 MHz – you can try running the chips at 950, 1000, 1100 and 1200 (use the –freq=xxx command line parameter to set these frequencies). We have found our test miner to perform best with 850 MHz, however yours might be able to function at higher frequency without problems (many HW errors), so you might want to try higher than 900 MHz all the way up to 1200. At 1000 MHz the device consumes about 9W and at 1200 MHz the power consumption might go as high as 10W, so there should be no problem with the cooling, however the chips might not be able to run well at so high frequencies and can give more or only HW errors.
