All About BTC, LTC, ETH mining as well as other alternative crypto currencies
VertCoin (VTC) has hard forked at block number 347000 bringing forth a new and improved Lyra2RE algorithm. This means that in order to continue using and mining VTC you will need to update your VertCoin wallet to the latest version as well as use a miner that adds support for the new Lyra2RE algorithm introduced with the hard fork. So far we only have working forks sgminer for AMD (source) and ccminer for Nvidia (source) from DJM34 that have support for the new version of the Lyra2RE algorithm, but we expect to see support added in other miners as well. You can download compiled Windows binaries for both miners from the links below and continue mining for the Lyra2v2 algorithm that VertCoin (VTC) is now using, also do not forget to update your VTC wallet. Do note that most coins will likely continue to use the older Lyra2RE algorithm for now, so this may cause some confusion as to what version of Lyra2RE is used by different altcoins other than VTC.
Back in February we’ve mentioned about a crowdfunding project for a new optimized Lyra2RE optimized kernel by a used called pallas on the Bitcointalk forum. Now the source code of the optimized kernel, along with the sgminer fork, has been released by pallas and we have compiled a windows binary of the miner for everyone that is interested in trying it out on Windows. Our quick test has shown about 640 KHS hashrate mining Lyra2RE with the compiled binary and the optimized kernel on a non-overclocked Radeon R9 285 GPU (with slight factory OC of the card) by increasing a bit the intensity from the default 15. The result was achieved using the AMD 15.4 Beta driver, though you might want to use the latest official 14.12 release for better performance. You are welcome to experiment and report what hashrate you are getting with this sgminer fork and optimized kernel on your GPU. Do note that this fork of sgminer only comes with kernels supporting Lyra2RE, therefore it is not intended for mining with other algorithms.
