Would you consider cryptonight instead? That would turn me into a more generous donator ^^
I'm guessing I'm out of luck though, if I understand correctly, tsiv's miner will be a pain to merge...

from my system: 980: 9.6MH/s/9.7MH/s
                       750ti 3.1MH/s
                       780ti 6.1MH/s
I think you have missed something, I don't think there should be so much difference

780ti 6.1MH/s is pretty good. Did you try to increase the intesity to the limit? f.eks -i 19.9 or -i 20.5?
The default intesity in the miner is set to run on 1mb cards. But with compute 5.2 the default is increased. I case on the compute version and not the memory..

didn't even know there was an intensity   I will check again
edit: 6.2MH at 19.9 and 6.08MH at 20.5

ccminer 1.0 did 2.8 MHASH on the 780ti. (10 may 2014)

The latest software is 221 % faster

That's awesome!

Yes this version is bether on the pools when mining on high intensity. The old version only found one solution below target, this version is submitting 2 solutions. Code forked fronm 1.5.1 (tvprovet's work)

Hi SP.
I'm mining X13 on regular pool (not multipool).The hashrate showing by the pool is lower than what the ccminer shows. And there is "set stratum difficulty to x.xxxx" message appearing quite a lot.
I tried versions from 17-20. The same scene. Hashrate is lower (from 14mhs on ccminer to only 8-9mhs on pool). I then tried older version 8 and it works better (13mhs miner 12mhs pool) I have standard setting in .bat file. Do i need a manual set up of diff per rig or is there something else that I'm missing? Switching back to version 8 now...
I would appreciate any help.
Thank you.

Wich card is this? you can to change the -i parameter. (intensity) If you are not using this card to display graphic -i 20.5 used to be the best for maxwell cards (750 -980). but it can crash if you have many cards.

The diff should be set in the password of the pool. Try the password -p d=0.02

Thanks for your help.

6x 750ti Gainward rig. Intensity parameter does not do anything. 20 crashes the rig, lower brings no improvement. I will try the password tomorrow. Now back to v8 again

did a rapid test with lyra2, the cpu usage is awfully high (I have a noisy cpu cooler...) 50% usage... against 5~7% in my version.

what did you do ?  
 
I was thinking, may-be I could use tpruvot interface, but 50% cpu usage is a big red flag for me... so please fix this...
(not the case for x11... though, but I don't use x11...)

You should merge his interface and api I'm sure that they aren't the ones causing the CPU usage, but I've noticed it too on lyra2.

it should come from the interface I use the same code in the legacy interface and the cpu usage is normal...
Main problem for me to move in (beside cpu usage), is the fact that m7 has been ditched    and I would need to rewrite everything (again) again on the interface, and that was particularly painful the first time...

[Epsylon3]

m7 has been... skipped

Using cudaDeviceSynchronize() was probably not a good idea.

i was about to say : its in lyra2_cpu_hash_32

and i think you can even remove the line else, no impact on hashrate

indeed much better (I did saw that, but tried to remove all the (my)cudasynchronize and it didn't change anything, putting them back works) actually.

Time to make a neoscrypt port for NVIDIA. Can we beat the opencl code by WOLF0?

now this would be VERY nice ...

i am changing ALL the cards to 750ti OC ( Gigabyte to be exact ) and will be testing it with the initial 11 cards i have currently ...

i will be more than willing to guinea pig and test neoscrypt on these cards the moment you have something out ...

not to sound greedy, but donations are a better incentive than guinea pig  

[tbearhere]

Version 20 is here (windows executable):

Faster x11 (+100KHASH(750ti))
faster x13,x14,x15,x17
fixed hashing for old cards.

source

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


One exe this time. Compiled for compute30,32,35,50,52

some algos don't work.
someone say WOLF0 open source...gotta find that.  
Edit: I can't find it.

about the supported cards, ive seen yesterday a bunch of new Quadro card made for the office... and all are SM5.0, some with 2GB, some with 4GB and more... But only a few are affordable (<200€) like the K620

http://www.pny.com/nvidia_quadro_k620 ... a bit curious about the perfs

384cores... that's a little more than half the number of core of the 750ti...
128bit mem bus
32-bit floating point...


I fail to see the interest...

Can you give a guess on the hash rate for the 750ti.

Once it is written, I will, but right now, it is a bit prematurate

I have some improvements in the lyra2RE implementation, but will keep the kernals private.

hehehe ... i know this ...

which is why MY version of 'guinea pig' is to mine FOR you as a donation to the btc address via westhash ( as this is the closest to adelaide australia ) ...

ive done this many times before - and it works ... my entire farm will be pointed to the donation btc address - which usually buys you a beer or two hehehe ...

i think thats better than mining for myself - transferring into my wallet - then transferring into your wallet as a donation ... AND you can keep track of it by watching the progress at westhash ... ( hint Wolf0 just recently ) ...

i mainly mine x11 - which is my preferred algo and the main one for granitecoin - but have no issues setting the farm to the algo that needs doing ... if only we can get a crap load more hashes for nvidia cards with x11 ...

btw - you guys and the work you are all doing is awesome ...

im happy to give details of the farm if you need them ...
