All About BTC, LTC, ETH mining as well as other alternative crypto currencies
After the initial craze due to the scarcity of Zcash (ZEC) coins and the big demand the prices has skyrocketed, but now with the slow start of mining progressing and the total block reward almost at 4 ZEC things are starting to stabilize. The initial crazy high profit for mining and selling Zcash coins seems to be over and at the moment mining and selling ETH or ZEC does bring almost the same profit for some GPU miners, though not for all. Miners with older AMD Radeon 79×0 and 280X GPUs still have higher profit mining Zcash than Ethereum, but for users with RX 480 for example things are already on the line to switch back to Ethereum. Nvidia seems to be currently lagging as far as performance optimizations for Zcash go, so the profitability there could be better for another algorithm or mining for another perspective in the long term crypto coin might also be a viable option.
You can keep track of the current profitability with the help of some useful mining calculators like the ones provided by CryptoCompare for both Zcash (ZEC) as well as for Ethereum (ETH) along with a few other popular coins such as Ethereum Classic (ETC), Monero (XMR), DigitalCash (DASH) and Litecoin (LTC). Make sure you set the correct hashrate your mining hardware is providing for each algorithm to make a proper calculation as different GPUs do provide different hashrate for the various algorithms. Do note that Etheeum Classic might also turn out to be pretty profitable alternative as well for some video cards that are still providing higher hashrate for the Ethash algorithm.
We have compiled a Windows binary (64-bit only) from the latest ethminer 0.9.41 Genoil fork 1.0.7 beta for Nvidia CUDA as well as AMD OpenCL mining of Ethereum (source). The latest code comes with the addition of failover support for Stratum mode along with the already available in previous release failover support for the standard mining mode. You are welcome to download and try the compiled binary of the latest git code for the new 1.0.7 beta and the Stratum failover and if you experience problems you should report them. Check the included help.txt file and the example BAT file for more information on how to use the new Stratum failover mode. We are also seeing a tiny bit of performance increase on Nvidia using the CUDA mode and apparently using the OpenCL on Nvidia should now also provide similar performance as CUDA (was slower before), there should not be no change in hashrate on AMD GPUs.
The fork of ethminer from Genoil that is specifically optimized for Nvidia CUDA GPUs has been updated to a new beta version – Ethminer 0.9.41-genoil-1.0.6 (source). The latest release of Genoil’s ethminer for CUDA comes with some fixes and new useful features, so if you are using it you might be interested in checking the new 1.0.6 beta, but be aware it can have some bugs. The latest version by default should run on all available CUDA GPUs like it does for OpenCL, it has an option to delete old DAG files that are just taking up space, comes with Stratum support and an option to set a failover pool in case the main one fails for some reason. You can check the help.txt file for the new options available in the latest release and yo are welcome to try them and report if everything works Ok for you. The fork from Genoil, although targeted at Nvidia CUDA miners, will also work on AMD OpenCL GPUs, but there it should not be any different than from the default ethminer that is OpenCL only.
