All About BTC, LTC, ETH mining as well as other alternative crypto currencies
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.
We have compiled a new Windows binary from of sgminer version 5.1.1 from the latestsource as it includes some fixes and optimizations since our last binary release. The latest sgminer 5.1.1 should also have better performing WhirlpoolX implementation thanks to Wolf0’s kernel getting integrated. The idea of the official sgminer is that it combines almost all of the available algorithms in a single miner package and that is what makes it useful for GPU miners along with a functionality that should allow you to easily switch between them. Do not that the performance of all of the various kernels included in the official sgminer may not be as optimized as in some dedicated releases for a specific crypto algorithm out there.
Earlier this month when sgminer has been updated to version 5.1.1 (source) it has turned out that there are some issues with the newly added Lyra2RE support. This issue has been addressed and now the latest sgminer 5.1.1 should have no more trouble mining Lyra2RE on compatible OpenCL GPUs, so you might want to give it a try, though it might not be the highest performing Lyra2RE miner out there. The idea of the official sgminer is that it combines almost all of the available algorithms in a single miner package and that is what makes it useful for GPU miners along with a functionality that should allow you to easily switch between them.
