New build with more hashing power in most algos.

from release 38 we have

-faster keccak
-faster fugue
-faster hamsi
-faster aes
-faster echo
-some bugfixes

1.5.39(sp-MOD) is available here: (15-feb-2015)

https://github.com/sp-hash/ccminer/releases/tag/1.5.39

The sourcecode is available here:

https://github.com/sp-hash/ccminer

thanks man keccak is faster by 15000 to 17000 khash on 970 from realase 38, thanks for advice you give me a week ago about crashing driver but nothing worked i think that mjollnir algo is broken in all ccminer realases for 970 not just yours. I have only mjollnir crashing and few other people from this forum pmd me that have same problem all of them have 970gtx.

I am not sure but this card runs proper on all ccminer50.exe files, but its not indeed not a new maxwell its the CK110 gpu

ahh only maxwell this version
wait are you sure the other ccminer 5.0 runs perfect

My mod will work, but I didn't compile it for you card in the exefile. This is a maxwell mod, and all the improvements are only tested on maxwell cards. I don't know how the performance is on older cards. It's probobly slower than the other ccminer forks.

lol
i just wanted to ask whats going on

Your card is compute 3.5 and this miner is compiled for compute 5.0 and higher. You will have to compile a version yourself. (change compute version in the project file to 3.5)
But not sure how fast it will run though...

For both R38 and R39, 750 Ti get error "Cuda error in func 'x11_sim512_cpu_init' at line 634 : out of memory." when running x11 in HamsterPool. No such error with x11 in YAAMP.
Edit: Upon further testing, running up to 3x 750 Ti has no error (i.e.: only 4x and beyond get the above error). To run 4x and beyond, I have to use -i 18 to run fine. Error could be unique to HamsterPool only.

I get this error sometimes too on rigs with 6-7 cards, or with a 960 card. The default intensity is a bit high. Ho ever if you restart the miner it usually works. It seems like the driver is freeing up som memory when the out of memory exception is triggered.

Workaround: Restart the miner a couple pof times until it starts, or lower the intensity. -i 18

My GTX 780 limited to 80% power
core 1097 mhz / memory 3100
at hamsterpool :

x11: 4613 kh
x11 bluecoin performance 5312 kh

after new case and better cooling i might test full speed its limited to run maximum temp of 70c now
pretty darn good speed already with so much limits
oops lol different ccminer
lol
the new 39 crashes

Good job!

ccminer r39 on 750 Ti at +150 core and stock memory solomining to avoid vardiff fluctuation:

x15 2120
bitcoin 216000

spreadminer v5: 1730

On a sidenote, starting ccminer with --cpu-priority 5 sometimes freezes the PC without ever starting hashing so I'm not using it and I manually set the process priority to realtime after it started.

hmmm, 750 without Ti works fine on hamster. Maybe you should try to play with --diff parameter.

keccak on NiceHash:
150mhs

Good rates for a non TI card.
I think the kernals needs to be finetuned for each algo. When I set optimal launch configs in the quark kernals it slows down the the x15 since they share kernals.
I might need to duplicate kernal calls to be able to tweak the optimal hashrate for every algo.

I need to do a new build. The source should work. I forgot to do a clean before rebuilding, and get some old files.

edit: a new build has been uploaded. This build is 200kb smaller than the last one when unpacked

please test other algos as well. Quark,qubit,fresh what is your speed?

In order to raise tangible funds to motivate GPU miner devs, I am now hosting a donation address for Bitcoin.

1K6cUbtsn5xinD8XfjnTn7UnsMriLhZaGD

The first GPU miner to be created (AMD or Nvidia) and published under an open source license will receive all the money from this fund.

I'm putting in 0.25 BTC of my own money. I encourage everyone to donate what you can to help make this a lucrative bounty.

The GTX750 (non ti) has only got 512 cuda cores, while the gtx750ti has got 640 cores. A radeon 280x has 2048 cores.

But the 512 core gtx beats the 2048 core AMD:

http://cryptomining-blog.com/wp-content/uploads/2014/07/sph-sgminer-fresh-windows-580x301.jpg

I have two Sapphire Toxic R9 280X cards with Hynix GDDR5 memory on board.
I overvoltaged them upto 1.3 V and set 1240 MHz for core and 1850 MHz for memory.
I use cgminer 5.1.0 with radeon drivers 4.7 RC3 installed.
Each card produces 5 MH/s

sp_ if I read this right he pointed his wish to scrypt chacha & scrypt jane coins which are not that unprofitable as scrypt.
a single 750ti could make above 500hash/s on nf16 (YAC) which was some weeks ago the best deal arround here.
AMD sucked at this time because they had no optimized miner. But this changed.

Yes, I though he ment Normal Scrypt. When the 750ti came out last year I bought a few and started mining scrypt. The price of the 750 ti was around the same a gridseed ASIC scrypt miner. The gridseed used less power than the TI, so it would seem more profitable to buy. Both had a hashrate of around 350KHASH.

Now one year later the TI is producing 18 times more money than the asic gridseed scrypt.

Just think about this the next time you order a ASICminer.

If you want to support the development, please donate and recieved my private spreadcoin miner. I hope to release 6 this weekend with more hashing power. Free to the donators.
