All About BTC, LTC, ETH mining as well as other alternative crypto currencies
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.
So long with Heavycoin (HVC) being a CPU only coin, now there is an OpenCL miner available for GPU mining the coin with a much faster speed than on a processor. We have compiled the modified version of cgminer 3.7.3 with Heavycoin support for windows and you can download the binary from the link below (source). We are getting about 5 MHS on Radeon R9 280x GPUs as you can see on the screenshot. We have tested the miner and can confirm it is working fine on the 1GH HVC pool, though it may also work on others as well. Due to the rapid increase in pool load you might want to try using hvcpool.1gh.com and hvcpool2.1gh.com as backup, also make sure configure the miner. And soon we may also see a CUDA miner for GPU mining Heavycoin also available from the developer of cudaminer as well. So no longer point in mining HVC on the CPU only anymore.
