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

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.

ccminer-1-6-git-tpruvot

Recently we have been compiling and releasing windows binaries of the ccMiner fork by SP that is optimized for newer Nvidia GPUs based on the Maxwell architecture, but tpruvot has been active lately and we have decided to compile and release a windows binary from his latest source. The windows binary we have compiled for ccMiner 1.6-git by tpruvot (source) is with support for Compute 3.0 or later Nvidia-based video cards, unlike the SP releases that are Compute 5.0 and 5.2. This means that if you are using older video cards you should go for the tpruvot release as the SP fork will not function on these, newer Maxwell GPUs however will get much better performance with the SP fork. Below you can find a quick comparison we did with the latest ccMiner 1.5-41 fork from SP and ccMiner 1.6-git fork by tpruvot using a GeForce GTX 980 GPU running at stock frequencies.

ccMiner 1.5-41 SP:
X11 – 9098 KHS
X13 – 7230 KHS
X15 – 6226 KHS

ccMiner 1.6-git tpruvot:
X11 – 8239 KHS
X13 – 6669 KHS
X15 – 5830 KHS
