bfgminer-gridseed-support

Another software miner now has support for the 5-chip Gridseed GC3355 BTC/LTC ASIC devices and that is bfgminer, though you should note that there is a separate branch that supports the Gridseed hardware and the official 3.10.0 release is not compatible. The version that you can download below compiled for windows is the one with Gridseed support and you can also use it for Scrypt GPU mining, though the command line we have provided in the BAT file is only going to start bfgminer and look for Gridseed devices (remove the -d gridseed option to use GPUs too). Also note that the command line starts the miners with 850 MHz operating frequency that should result in about 360 KHS scrypt mining hashrate (60 over the stock 300 KHS) – should be stable option for good overclock performance with low to no HW errors, but your results may vary. You can get down to 800 MHz if you are getting more HW errors, or try to get up to 900 MHz if you get no HW errors to see if you can get 380 KHS stable.

This version of bfgminer shoudl work with both the earlier 5-chip Gridseed ASIC devices as well as the newer revisions, it detects and work with our miners using both the newer STM32 Virtual COM port driver as well as the older CP2102 USB to UART Bridge Controller. Note that bfgminer requires the devices to be working with their standard virtual COM ports and not to have the drivers replaced with Zadig with WinUSB like cgminer does. If you have installed the WinUSB drivers you may need to Uninstall the drivers and unplug and plug the ASIC devices so that the default driver is installed again. Alternatively you can try to install the GridSeed.inf driver you will find in the miner archive. Note that the version of bfgminer provided here is only for Scrypt (LTC) mining on the 5-chip Gridseed ASIC devices!

cudaminer-blakecoin-support

The latest beta version of cudaminer has support for the Blake-256 algorithm available, however there is still no official release available compiled for windows that has the new code with Blake algorithm support, so we have compiled it and provide it to you for download. So far the Blake-256 algorithm is only used by two crypto currencies – Blakecoin (BLC) and Photon (PHO), but the good news that if more come out you will be already ready to mine them with Nvidia GPUs as well. Note that the hashrate you will be getting mining Blake-256 crypto currencies will be in megahashes and not in the kilohashes range and that is pretty normal for this algorithm. Mining on AMD GPUs will still bring significantly higher performance than on Nvidia, but still you can mine on Nvidia as well.

cudaminer-2014-02-28-gpucoin

If you want to mine GPU Coin with Nvidia GPUs you will need to use the cudaminer software miner. GPUC uses Scrypt-Adaptive-Nfactor and not the standard Scrypt algorithm, so you need to run cudaminer with the –algo=scrypt:2048 parameter and not just with –algo=scrypt. Do have in mind that you should see about half of the typical Scrypt hashrate you get when you start mining for GPU Coin and that is absolutely normal due to the different algorithm being used.

We have tested mining for GPU Coin with a GeForce GTX 750 Ti video card running at stock frequencies and got about 134 KHS hashrate, after overclocking we’ve managed to get up to about 146 KHS. The kernel configuration that we found to work best was T10x24 on the GTX 750 Ti and this is the command line parameters we’ve used to launch the miner:

cudaminer.exe --algo=scrypt:2048 -o stratum+tcp://east1.us.stratum.dedicatedpool.com:3367 -u yourworker.1 -p password -i 0 -l T10x20 -C 1 -H 2

Below you can download the latest version of cudaminer 2014-02-28 for Windows with BAT files ready with the settings for mining GPU Coin, so you just need to configure them with your pool settings and start mining. Note that the default settings are the best for mining with GTX 750 Ti graphics cards, so you might need to change the kernel to another one based on your GPU or just remove the line setting up the kernel to use the autotune feature.
