All About BTC, LTC, ETH mining as well as other alternative crypto currencies
There is already a lot of speculation about the new AMD GPUs that are supposed to be announced in the next week or so and among all of the unofficial information there is probably a lot that will end up being the truth. So far it seems that apart from the new high-end Fiji GPUs that will use High Bandwidth Memory (HBM) all others will be a refresh of the currently available generation with maybe a bit more shaders or a bit wider memory bus, so you should probably not expect too much out of the net 300 series. The big question is about what level of performance the new AMD Fury video cards based on the Fiji GPU with HBM will be offering. AMD has been hinting that they are targeting a level of performance comparable to that of Nvidia Titan X, but it is not only abut performance, but also about power usage when talking about crypto currency mining and then there is also the cost of the video card. So if the Fiju GPUs that are to be used in the AMD Fury video cards are able to achieve similar performance with a bit higher power usage, but at a significantly better price they may end up be quite interesting. Especially if they do come with a water cooling solution already installed on them, ensuring cool and silent operation – perfect for GPU mining.
However we doubt that the price will be much lower than that of a Titan X and that will make it a bit too expensive for use for crypto mining, just like is the case with the Titan. On the other hand Nvidia has recently released the more affordable and slightly stripped down version of the Titan X in the form of GTX 980 Ti. The good news based on our initial testing was that the GTX 980 Ti was offering a performance very close to that of the Titan X at a much better price making it the more interesting choice for crypto currency mining, especially if you get the card as a gaming / crypto mining solution (mining while not using it for gaming). There is also already some talk that AMD will have two models based on their new Fiji GPU with HBM memory available, so the possibility to get one that will compete with GTX 980 Ti and one that will compete with the Titan X is actually quite high. Based on past experience with AMD GPU mining however it may take some time and maybe some tweaks to optimize the existing OpenCL miners to take full advantage of the new GPUs (not the refresh models). That is especially true considering that the open source miner development for AMD GPUs hasn’t been that active lately, unlike the developers of open source miners for Nvidia GPUs that are doing great job in optimizing and fixing issues constantly. Hopefully the new releases from AMD will finally spark some recovery in the AMD GPU mining ecosystem, well we are going to see pretty soon…
We have updated our NiceHash Control tool package with sgminer for use with AMD Radeon R9 280X or 7970 GPUs to the latest NiceHash Control version 1.1.1 that adds up some new useful features. The idea for this tool is to sell your hashrate at the NiceHash service making the highest possible profit by switching to the most profitable mining algorithm all the time. Our ready to use package supports the X11, X13, X15 and NIST5 algorithms as we consider that these are currently the most profitable ones as well as the ones that will use less power and generate less heat. The update available here also introduces backup pools for each algorithm, so that when NiceHash is down you will move to the TradeMyBit pool as a backup (you need a registration there and to setup the backup pool’s user and password to your own).
What you need to do in order to use our AMD Radeon 280X mining pack is to edit the config file and set your BTC address, edit the backup pool settings in the MINERS.bat file and then just start the AUTOSTART.BAT file to fire up the software. What is left is to monitor your earnings on the NiceHash website, and you can check the log.txt file for information what algorithm was switched to and when. This version of the package does take advantage of the failover pool feature that sgminer supports, something that is still not available in the ccMiner for Nvidia, where we have to use a workaround to provide a backup pool support. If you like this tool and our AMD Radeon 280X mining pack based around it, don’t forget to send a tip to the author of the NiceHash Control software. Another important note, make sure to use the latest AMD beta video drivers in order to maximize your hashrate.
We have already posted a package with the NiceHash Control tool for the GeForce GTX 750 Ti GPU for maximizing your mining profit by selling your hashrate on NiceHash. Today we have packaged the NiceHash Control tool with sgminer for use with AMD Radeon R9 280X or 7970 GPUs and having set the hashrate you get from a single card in the different algorithms. The tool will mine the most profitable algorithm choosing between X11, X13, X15 and NIST5 taking into account the hashrate you get with the various algorithms and checking if it should switch every minute based on current profitability.
All that you have to do is to set your BTC payment address in the config and run the AUTOSTART.BAT file, unless you have to do some hashrate changes in the config as well based on your mining rigs. You might also want to check out the Readme file for some extra information about the NiceHash Control tool. So far the tool is working pretty well, though it needs some more polishing, do note however that it is only available for Windows. Do note it is recommended to upgrade to the latest AMD beta drivers for optimal hashrate if you are still running on older version.
