Updated ccMiner 1.6.2-git fork by tpruvot Now Available

21, Apr 2015

ccminer-1-6-2-git-tpruvot

We have compiled an up to date Windows binary from the latest ccMiner 1.6.2-git by tpruvot (source). The ccMiner fork from tpruvot is with support for Compute 3.0 or later Nvidia-based video cards all the way up to the latest Compute 5.2 GPUs from Nvidia. The latest version includes some fixes and most notably the addition of Scrypt, Scrypt-N and Scrypt-Jane algorithms that are ported from CudaMiner that has already been outdated and not supported for a while. Not that it is much profitable to mine coins using these algorithms at the moment, especially Scrypt ones on the GPU, but still now you have support for them in ccMiner available. Since our last binary release there was also the addition of Double Skein Algo (Skein 2) that is being used by crypto coins such as Woodcoin. Our windows binary is compiled with VS2013 and supports Compute 3.0, 3.5, 5.0 and 5.2 GPUs, you can download and try it below, there is an example BAT file setup for testing.

Nvidia GeForce GTX 960 Coming Soon to Replace GTX 750 Ti

15, Jan 2015

There are already a lot of rumors over the internet, including some leaked photos, specs and gaming performance results of a new Maxwell-based GPU coming from Nvidia next week – the GTX 960. The final specifications of the GTX 960 are not officially announced, but according to the information available the card will come with 1024 CUDA cores, 64 TMUs, 32 ROPs, 128-bit memory bus or essentially half of the specs of the GTX 980. The expected power usage is around 120W or around double that of the GTX 750 Ti with an expected end-user price of about $199 USD ($149 for the 2GB GTX 750 Ti). So with just $50 USD more you could be able to get a new Maxwell-based GPU that could as well provide twice the crypto mining performance of a GTX 750 Ti GPU and if this is indeed true when we see the final card and the actual performance it offers it will be quite an interesting alternative to GTX 750 Ti for mining rigs. That of course is still in the form of speculations as we don’t have officials announced product and specifications, but our expectations based on the leaked data so far suggest that about twice the performance of GTX 750 Ti is possible. We are going to be keeping an eye out for the announcement of the new GTX 960 graphic processors from Nvidia expected next week and are going to be trying out a card as soon as we manage to get our hands on one of these to see what kind of performance will it offer for crypto mining. So stay tuned for more information when it becomes available.

Nvidia GeForce GTX 970 OC vs GTX 980 Hashrate Results

Last month we have done some initial GeForce GTX 980 crypto mining benchmarks with the announcement of the new Maxwell GPUs from Nvidia. Now we got our hands on a Gigabyte GeForce GTX 970 G1 Gaming video card (GV-N970G1 GAMING-4GD ) and have decided to run some tests to see how well it will fare against a standard reference design GTX 980 again from Gigabyte (GV-N980D5-4GD-B). The reference design GTX 980 we’ve used is running at stock frequencies, including the boost one and the results below are with the card not additionally overclocked, even though it can take quite an increase in the frequency. The Gigabyte GeForce GTX 970 G1 Gaming card however is factory overclocked to a really high frequencies as compared to the stock ones and there is not that much left for the user to add, though some extra overclocking is also possible. The G1 Gaming card from Gigabyte also comes with the company’s Windforce cooler that proved to be a very good and silent cooling solution even when you overclock. Also the GTX 970 model is with a factory increased max TDP level to go along with the overclock the 100% of the power limit actually represents 250W instead of 145W or 165W. This leaves a lot of headroom for more power hungry crypto mining algorithms, even though in our tests not a single algorithm was able to hit 100%. The closes we got was about 90% of the increased TDP reached with the groestl algorithm most others were keeping in the 60-70% of the 250W TDP limit.

The results you can see in the table above are achieved with the ccMiner release 1.4.5-tpruvot using Compute 5.2 compiled binaries. This might not be the single best performing fork of ccminer available, however it is probably the one with most comprehensive support for various crypto algorithms (we tested with all of the supported ones) and with support for Compute 5.2. Some other forks might be able to provide slightly better hashrate on a specific algorithm, but the idea here was to do a comparison between a reference GTX 980 and a factory overclocked GTX 970 to see what you can expect in terms of performance. The results are pretty interesting as the factory clocked G1 card is getting very close to a stock GTX 980 and with some extra user overclock it might even achieve the same results. Considering the fact that the GTX 970 is still much better priced than the GTX 980 we can easily conclude that the GTX 970 and especially GTX 970 G1 Gaming from Gigabyte is a really good choice not only for gaming, but also for mining crypto currencies.
