Updated ccMiner 1.5-git Fork by tpruvot With Extra Nonce Support

23, Nov 2014

ccminer-1-5-git-tpruvot

We have compiled a windows binary from the latest (source) of ccMiner 1.5-git fork by tpruvot as he has added support for the Extra Nonce feature used by services such as NiceHash or WestHash to maximize the mining performance. So if you are currently leasing your Nvidia GPU mining hashrate at NiceHash you might want to try out the latest code of this ccMiner fork. Do note that there is still no official release of 1.5 by tpruvot and this windows binary is compiled from the latest source available on GitHub. There are also some increases in performance as compared to the previous release, so you should notice a slightly better hashrate in some algorithms. The windows binary available for download below is compiled for Compute 3.0, 3.5, 5.0 and 5.2 Nvidia GPUs using VS2013 and CUDA 6.5, so make sure you have updated your drivers if you still don’t have ones installed with CUDA 6.5 support.

AMD and Nvidia GPU Miners For SpreadCoin Now Available

21, Nov 2014

spreadcoin-nvidia-gpu-miner-hitting-a-block

SpreadCoin (SPR) is not a new coin, but it was a mine-able only with CPU up until yesterday when an AMD GPU miner was released and today the coin also got an Nvidia GPU miner that is apparently much faster than the AMD one. The AMD OpenCL miner is available on the official SpreadCoin GitHub page (source) and there is a compiled windows binary available on the official coin website. You can get the spreadminer for Nvidia GPUs thanks to tsiv who created it (source), there is an official windows binary release for Compute 3.0 to 5.2 GPUs available on his GitHub page as well that you can download and use directly.

SpreadCoin uses SpreadX11 algorithm and does not use mining pools, you can only solo mine the coin, so you need to make sure that you have created spreadcoin.conf file with the required settings to be able to connect the miner to the wallet running on one of your computers. The config file needs to be placed in the Users\ YOURUSERNAME \AppData\Roaming\SpreadCoin folder and named spreadcoin.conf and then you need to restart the wallet, also make sure that you have downloaded the block information before trying to run a miner. You can find an example settings for the config file below if you haven’t solo mined yet and this will be the first coin that you try and don’t forget to set the username and password in the miner config to be the same and also allow any additional IP addresses or a range that will be connecting to the wallet:

rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
rpcallowip=192.168.0.*
rpcport=41677
port=41678
gen=0
server=1

For the moment you would probably want to try out the coin if you have an Nvidia GPUs as they are performing much better in terms of hashrate than what you can get on AMD GPUs. On a stock Radeon R9 280X we managed to get just about 800 KHS using the official OpenCL miner and with the Nvidia CUDA miner on a GTX 750 Ti card we easily got over 1400 KHS, trying it out on a GTX 980 we’ve managed to squeeze close to 4500 KHS. So if you have some Nvidia GPUs, especially Maxwell-based cards you might want to mine some SpreadCoins while the difficulty is not way too high to be worth mining with one or just a few cards. Also do not forget that with solo mining luck plays an important role as well and you might get lucky and find more blocks in short time or not and wait more for little blocks, so give the miners some time.

New Updated ccMiner 1.4.7.SP Fork with Optimized Kernels for Maxwell

17, Nov 2014

ccminer-147-sp-maxwell-optimized-new

We have compiled a new windows binary of the ccMiner 1.4.7.SP (source) fork with optimized kernels for Nvidia Maxwell GPUs supporting Compute 5.0 (GTX 750 / 750 Ti) and Compute 5.2 (GTX 970 / GTX 980) that includes some slight performance improvements for the Blake, Echo and Shavite algorithms as well as other more general optimizations that should result in slightly faster hashrate on some of the algorithms supported by the miner. The windows binary you can download below is compiled with VS2013 and CUDA 6.5 and is only for Nvidia Maxwell GPUs, it will not worl on older hardware – for older Nvidia cards you can use tpruvot’s ccMiner fork that should also work on Compute 3.0 and 3.5 GPUs.

– You can download the ccMiner fork by SP optimized for Maxwell GPUs for Windows OS here…
