Updated Windows Binary of the ccMiner 1.5.43-git Fork by SP for Maxwell

24, Mar 2015

ccminer-1-5-43-sp-mod

A new Windows binary compiled from the latest source code of ccMiner 1.5.43-git SP-MOD fork of the Nvidia GPU miner optimized for the latest Maxwell-based video cards by SP (source). The latest version comes with some fixes and some small performance improvements in multiple algorithms. The SP-MOD fork is designed for running on 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.

How Intensity Affects Performance in ccMiner

22, Mar 2015

ccminer-sp-mod-intensity

After a reader suggested that the difference in performance between different forks of ccMiner can be a direct result from the use of different default values for intensity we have decided to dig a bit into how the -i value affects hashrate. We have used ccMiner 1.4.2 SP-mod as an example along with WhirlpoolX on a GeForce GTX 980 GPU. The range of intensity that we have tested is between 10 and 26 with 26 being the default one for the ccMiner SP-mod. You can go with intensity of under 10, but the performance will drop further and there is actually no reason to do it, going over 26 is also possible but will hardly result in any performance increase. Going below Intensity value of 26 may be good thing to do if you are mining on your primary video card on a computer that you are using, so lowering the intensity can be useful in making things more responsive (even 1-2 steps can make a difference without much performance loss). You can see the results with different settings for intensity on our test setup below:

WhirlpoolX – GTX 980:
Intensity 10 – 4377 KHS
Intensity 11 – 8157 KHS
Intensity 12 – 17252 KHS
Intensity 13 – 34283 KHS
Intensity 14 – 67009 KHS
Intensity 15 – 99110 KHS
Intensity 16 – 107568 KHS
Intensity 17 – 140759 KHS
Intensity 18 – 175111 KHS
Intensity 19 – 199488 KHS
Intensity 20 – 214410 KHS
Intensity 21 – 222802 KHS
Intensity 22 – 225320 KHS
Intensity 23 – 228779 KHS
Intensity 24 – 231550 KHS
Intensity 25 – 231755 KHS
Intensity 26 – 232204 KHS

Updated ccMiner forks With Support for WhirlpoolX Now Available

9, Mar 2015

ccminer-sp-whirlpoolx

The WhirlpoolX algorithm is now supported in both the latest updates of the ccMiner forks from SP (source) and Tpruvot (source). So we have compiled windows binaries from the latest source for both miners and decided to test the performance we are getting mining the WhirlpoolX altcoin Vanillacoin (VNL). Do note that the sp-mod fork of ccMiner is optimized and supports the newer Computer 5.0 and 5.2 Nvidia Maxwell GPUs where the performance is maxed out while the tpruvot fork supports Compute 3.0 or newer video cards. We have tested the performance we are getting on GeForce GTX 980 GPU with the two miners, the SP version as expected gives out higher performance on a Maxwell card as expected with about 233 MHS while the tpruvot fork is not that much slower with about 222 MHS mining WhirlpoolX. So if you are mining WhirlpoolX on Nvidia-based video cards or leasing your hashrate you might want to update your miner to the appropriate version depending on your GPUs.
