gtx-750-ti-ccminer-spmod

Recently we have picked up the last 20 releases of the ccMiner SPMOD fork for Maxwell and tested them on a Gigabyte GTX 970 WF3 GPU. running at stock frequencies to see what has happened with the hashrate in the X11, Quark, NeoScrypt and LyraREv2 algorithms. There were users that wanted us to repeat the same test with a GTX 750 Ti GPU, so we have picked up an eVGA GeForce GTX 750 Ti video card and repeated the same tests. The first version we tested with ccMiner 1.5.53-git SP is from early July and looking at the results it seems that the most notable improvement is with Quark as well as some slight improvement with X11. Lyra2REv2 support has been added in release ccMiner 1.5.60-git SP, so there are no results prior to that, it seems however that the initial versions and the last one have pretty much the same hashrate with some drop with some in-between versions. The NeoScrypt hashrate hasn’t changed much, there is some slight variance with different versions probably due to the Boost frequency of the GPU variating a bit. Do note that these are results with publicly available and open source code, there could be some higher performance private miners also available and you might be able to squeeze more performance with different intensity settings (other than the default ones) as well as by overclocking the video card.

Since we’ve been closely following the development of the different ccMiner forks and have been compiling Windows binaries for most of the updated versions we have decided to do an interesting test. We have picked up the last 20 releases of the ccMiner SPMOD fork for Maxwell and tested them on a Gigabyte GTX 970 WF3 GPU running at stock frequencies to see what has happened with the hashrate in the X11, Quark, NeoScrypt and LyraREv2 algorithms. The first version we tested with ccMiner 1.5.53-git SP is from early July and looking at the results it seems that the most notable improvement is with Quark as well as some slight improvement with X11.

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
