Today I was looking for some cheap FPGA miners, and found the following on aliexpress:

http://www.aliexpress.com/item/400MH-s-FPGA-Bitcoin-Miner-X-1Pcs-Ship-Now-By-DHL/1660168916.html

FPGA miner for $16 or $24? Is this for real? These offers look pretty scammy, they are copy-and-paste, pictures are the same everywhere, sellers without feedback. Did anyone buy these?

SPH-SGMINER

GPU miner for DarkCoin, QubitCoin, MyriadCoin, Quark, Fuguecoin, INKcoin, AnimeCoin, GroestlCoin, Sifcoin, Twecoin and MaruCoin

This project is a GPU miner for cryptocurrencies using combinations of hashing algorithms from sphlib library. It's based on popular sgminer. Currently you can mine DarkCoin, QubitCoin, MyriadCoin (groestl), Quark (clones too), Fuguecoin, INKcoin, AnimeCoin, GroestlCoin, Sifcoin, Twecoin and MaruCoin with this miner. Support for more coins based on hash functions from sphlib (blake bmw cubehash echo fugue groestl hamsi jh keccak luffa shavite simd skein) will be added in the future.

Building on Linux:

Code:

./autogen.sh
./configure
make

You need a couple of dependencies beforehand. When in doubt, see README.

Example usage - DarkCoin:

Code:

GPU_MAX_ALLOC_PERCENT=100 ./sgminer -k darkcoin -o <host>:<port> -u <user> -p <password> -I 18 -g 4 -w 128

Example usage - QubitCoin:

Code:

GPU_MAX_ALLOC_PERCENT=100 ./sgminer -k qubitcoin -o <host>:<port> -u <user> -p <password> -I 16 -g 4 -w 128

Example usage - Quark and clones:

Code:

GPU_MAX_ALLOC_PERCENT=100 ./sgminer -k quarkcoin -o <host>:<port> -u <user> -p <password> -I 16 -g 4 -w 64

Without given -k argument value it defaults to scrypt kernel! If you have problems, read the DarkCoin thread from page 100, it contains a lot of information and solutions to common problems.

Important! A new option was added: --difficulty-multiplier. It allows to set stratum difficulty multiplier. For QubitCoin, Quark and Animecoin it will be usually 256. For Groestlcoin, Fuguecoin and Twecoin it will be usually 0.0039062500 (1/256). Default value is 1.0. If you have "share above target" errors then set it to 256. If difficulty required by pool is strangely large, set it to 0.0039062500 (1/256). Other values are unlikely to be used. Hopefully this will fix all remaining stratum problems.

Common problems and solutions:

• Error -11: Building Program (clBuildProgram) - execute miner from the directory where "kernel" directory is present
• HW errors - select correct mining algorithm with -k option
• still does not work - update Catalyst drivers to version 13.12
