All About BTC, LTC, ETH mining as well as other alternative crypto currencies
We got a request for an up to date windows binary of the latest official sgminer 4.2.1 (source), so here it is. Do note that this is the standard version of sgminer that in intended for Scrypt mining and does not support a lot of alternative crypto algorithms, for that you will need to get sph-sgminer, a fork based on an older version of the official sgminer, namely sgminer 4.1.0. From the link below you can download the latest sgminer 4.2.1 Scrypt GPU miner for windows.
We now have a merged mining pools for Blake-256 based crypto coins, currently supporting merged mining of Blakecoin and Photon, but for mining these you need a special version of cgminer with support for the algorithm being used by them. The Blake-256 algorithm hashrate is about 3x faster than what you are getting from the same hardware mining for Bitcoin. So for example with a Radeon R9 280X you can expect to get a hashrate of about 2-2.5 GH/s or more when mining Blackecoin (BLC) or other Blake-256-based crypto currencies such as Photon (PHO) for example. You cannot use the standard cgminer for mining Blake-256 crypto coins, you need to use a special version of cgminer with support for this algorithm (source) and you can download the windows version of cgminer 3.7.2 for Blake-256 mining below. Note that this version of cgminer is compiled with support for Blake-256 mining alone, you cannot mine other coins using different algorithms with it.
Mjollnircoin (MNR) is a HEFTY1-based crypto coin that is using the same algorithm like Heavycoin, though there is no reward voting support with MNR, so you will need a slightly modified miner in order to mine it even though the algorithm is the same as for HVC. We already have a ccminer update to support MNR for Nvidia GPUs and there is also a cgminer 3.7.3 with Mjollnircoin support available for AMD OpenCL mining (source). Do note that Nvidia is still faster in mining HEFTY1-based crypto coins such as Mjollnircoin (MNR). With the cgminer for MNR mining we are getting a bit over 16 MHS mining on a single Radeon R9 280X video card.
