amd-fiji-fury-gpu-hbm

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…

bitcoin-blockchain-data-files

If you are using the Bitcoin Core wallet to store your Bitcoins locally on your computer you have probably noticed that the Blockchain data files have already passed the 40GB mark (about 40.8 GB at the moment). With the increasing number of transactions happening on the network the increase of the files will continue to grow constantly and this is another aspect that will cause issues for users. Apart from the serious file size there is another aspect, the time needed to synchronize the Blockchain data from scratch is quite big and it is not only dependent on the harddrive’s speed, but also on the CPU you’ve got to process all the data. If you are using the default data directory on your C drive you might be experiencing some free space issues, especially if you use a smaller SSD system drive. The solution for this would be to move the Blockchain data files to another drive and run the Bitcoin Core client with the datadir parameter pointing it to the drive an folder you have moved the data files.

Alternatively you can go for a lighter version of a wallet that does not need all of the Blockchain data stored locally such as MultiBit or Electrum. And then there is also an alternative in the form of an online Bitcoin wallet, there are multiple options available to choose from such as Coinbase, Xapo and many others. Another interesting alternative for long term investments is to use your Bitcoins, or at least some of them, to buy Gold or Silver for example from a trusted precious metals dealer accepting BTC. Then there are also many other ways to invest Bitcoins, but you should be careful as there are quite a lot of scams out there promising very high and very fast returns on your investment, so you should be extra careful with such offers.

ccminer-1-5-52-sp-mod-new

Time for a new quick update in the form of a Windows binary compiled from the latest Git source code of ccMiner 1.5.52-git SP-MOD fork of the Nvidia GPU miner optimized for the latest Maxwell-based video cards by SP (source). This version includes some performance improvements in some of the supported algorithms such as Lyra2RE for GTX 970 and more Quark optimizations for improved hashrate, so as usual you might want to update for the best performance. As it seems that at the moment Lyra2RE and Quark are the most profitable algorithms to mine with GPU. The SP-MOD fork of ccMiner is designed for Nvidia Maxwell GPUs such as the already available GTX 750, 750 Ti as well as the newer GTX 960, GTX 970 and GTX 980. The Windows binary release we have made available here is compiled with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based cards with CUDA 6.5 and VS2013.
