I have modified and improved the speed of some of the hashing algorithms for the NVIDIA GPU's compute 5.0 or newer.
Most of the Hashimprovements are done by me, but some are done by djm34, Schleicher(klaus_t),Epsylon3(tvprovut),tsiv, and pallas.

ccminer-Maxwell.7z
~2750
~2090

~8350

Average of 5 x Gigabyte GTX 750 Ti (GV-N75TOC-2GI) with 120/160 OC, solomining to avoid fluctuation.

The highest I could reach overclocking a single card was slightly over 3000 kh/s (x11) which was reached at +300 core and +300 mem which is very likely not stable.

I will update this with my 970 rates if I get a chance tonight when the GF goes to sleep.

I have not mined x15 in quite a while, but I can get x11 soon and maybe x13/x15 in the next 24hrs.

My public(beta) miner is not so good. But still the fastest
The killer blake is not included. Smiley please note the blakecoin is hashing at 0.5% faster than the previous miner (blakecoin)

Reduce the mem speed and increase the core.

Just waiting for the exe file, then I will test it out on a EVGA GTX 970 (with and without OC), then I will donate

I am pretty excited to see any improvements!

Nope, TDP use at 90%, same as before.

Reduce the mem speed and increase the core.

Can't do that, 3Way SLI limits my overclocks, only the last card goes to the moon, the others burn in hell due to bad temperatures.

In 2 way spaced SLI I can get 235+Core stable in both cards.

Cheers

Here I have installed:

- Visual Studio 2013 Express

- Cuda 6.5 from nvidia

This will solve your problem.

I had the same error on the rig I tested this and all I had to do was to install both x86 and x64 redistributables.

Similar results with my gigabytes Wink SP miner is also easier on OC, less crashes.
I do like how djm implemented the average and variance of your submits. Makes comparison a bit easier Wink

I read 270W on both SPs and DJMs ccminer. This is + a load of hdds + my gtx760 idling + .... But no real difference in the wattage for me.
