All About BTC, LTC, ETH mining as well as other alternative crypto currencies
Siacoin (SC) is getting a lot of attention lately and there is now a new fork of the miner available made by Genoil (source). The Sia GPU Miner fork by Genoil is for OpenCL, though it works on both AMD and Nvidia and provides some performance optimizations along with other interesting features such as the ability to load external OpenCL kernel file that might be useful for people that want to try modifying or optimizing the CL file. Genoil reports that his optimized OpenCL kernel is capable of providing roughly +18% performance increase on a 7950 and we are seeing some performance boost on Nvidia as well, though more like 3-4% boost on a GTX 970. Nevertheless the fork by Genoil does offer some performance improvement over the Siacoin default miner as it has taken that OpenCL Go miner kernel as a base and even more improvements could be possible for faster performance.
We have a working 64-bit Windows binary available for download below that you might want to try. We have tested it and can confirm that it works on both Sia Nanopool and Siamining pool, though for some reason the hashrate reported by the miner is a bit higher for Nanopool than for the Siamining pool. Do note that this miner does require you to run a separate instance for each GPU in your system, it will by default run only on the first video card it finds. So while things do look very promising for this fork it apparently can use a bit more work to become as easy to be used as the Siacoin Go miner and maybe even better performance wise.
A few days ago we’ve covered the beta SIA pool from Nanopool, and now there is a second more interesting SIacoin mining pool open for public already available called Siamining. Nanopool is still in beta and apparently has some delays with payments, along with high minimum limits and uses PPLNS payment system, while the Siamining pool does seem to be out of beta already and offers more interesting terms, especially for smaller miners. The Siamining Siacoin pool uses a PPS (Pay Per Share) payment system with a slightly higher fee of 3% (to cover for the higher risk for the pool) and does payments every 6 hours. So no need to wait for a very high minimum balance (2000 SC minimum) or to wait for block confirmations before you get your SC payments sent to you, there is also a Long Polling support to minimize stale shares. We have been testing the pool for about a day already and it does seem to be working quite well already, so we do recommend that you check it out, especially for smaller miners.
Meanwhile we have also done some benchmarks using the Siacoin Go Pool miner (source) that uses OpenCL for mining SC on different AMD and Nvidia GPUs (the miner supports mining on Nvidia using OpenCL) and you can fidn the results below. Do note that Nvidia is generally slower than AMD in terms of performance with OpenCL, however the new Pascal Nvidia GPUs such as GTX 1070 and GTX 1080 manage to do quite well in terms of hashrate. When you factor in the very good profitability mining Siacoin it is worth checking it out, especially if you are wondering shoudl you continue mining Ethereum with the current low exchange rate and high difficulty when there are already some good alternatives such as SIA.
Siacoin Go Pool miner hashrate:
– GTX 1080 – 1945 MHS
– GTX 1070 – 1466 MHS
– GTX 980 Ti – 1220 MHS
– GTX 970 – 803 MHS
– GTX 950 – 385 MHS
– GTX 750 Ti – 301 MHS
– RX 480 – 872 MHS
– R9 280X – 849 MHS
– R9 290x – 1116 MHS
Alternatively you can go for dual mining Ethereum and Siacoin using the latest Claymore Dual Miner with ETH in the main focus and SC as a secondary crypto coin to fully utilize the resources of the GPU you are using. Just a reminder that the dual miner is only for AMD GPUs, so for Nvidia GPUs you still need to go for the SIA Go miner that you can download below (64-bit binary for Windows). A word of warning, the Siacoin miner is pretty heavy for the GPU, so be careful with the temperatures and power usage if your focus was lately on mining Ethereum that does not stress the GPU that much unlike other algorithms. The Siacoin Go Pool miner easily hits the TDP limits of the GPU while mining, so make sure your video cards are cool and that your power supply can handle the load.
Siacoin (SC) has been picking up recently and there have been talks about privet mining pools available, but the good news is that you can already GPU mine the SIA crypto tokens that are powering a decentralized storage network in an open pool. The open Siacoin mining pool already available is sia.nanopool.org and you can join it and start mining in no time. The pool does not need a registration, all you need to have is a wallet address – generate one with a SIA local wallet or use an exchange generated wallet from Poloniex or Yunbi. You can download the GPU miner for Siacoin written in in Go for pool mining (source) compiled and ready to be used from the link below (64-bit release for Windows) or use the latest Claymore Dual Miner that brings support for Dual Mining Ethereum along with Decred or Siacoin as a second coin (previously only Decred was available for dual mining).
The SIA Nanopool pool uses PPLNS payout scheme, has a fee of 2%, executes payouts once a day with a minimum payout currently set at 5000 Siacoins. Out test with the Siacoin Go miner for Siacoin shows about 1116 MHS as a hashrate for a single Radeon R9 290X GPU without overclocking, so you can have that number as a reference. The miner also works on Nvidia GPUs (it is still using OpenCL, not CUDA), as a reference number you can expect to get about 803 MHS from a GTX 970, do note however that for Nvidia-based mining rigs the go miner is the only choice as the Claymore dual miner is only for AMD GPUs. If you want to focus on mining Ethereum and mine Siacoin as a secondary coin and have AMD GPU mining rigs, then you can also try the latest Claymore dual miner version 5.0 that now gives you the choice for mine Decred or Siacoin besides Ethereum. Please report your hashrate and success in running the miner on different hardware, both AMD and Nvidia-based GPUs, in the comments below. should you decide to try mining Siacoin.
