sp_ does this ccminer support neoscrpyt?

Not yet. Noboby has ported it yet.

cgminer does neo/nvidia

How does nvidia compare to amd on cgminer?

I get 25KH/s with cgminer 3.7.8 for neoscrypt by vehre (and wolf) on Win 7 with a 550ti.  I have not been able to compile the same version on Linux and run with a 6x750ti rig.  It will compile, and run, but only produces HW errors for me.

Cgminer is not written to take advantage of Cuda architecture.  It supposedly uses OpenCL for Nvidia.  The Cuda masters have not been producing any Cuda optimized code for neoscrypt.       --scryptr

A suggetion sp_:

How about merging your and tpruvot's threads with the original CCminer thread, given that Christian updates the OP a bit to highlight other contributers since April 2013? I'll ask the same to Christian and tpruvot.

One CCminer thread would be much easier to follow then several as the case is now.

i remember djm, was working on it long time ago

[Handofmidas]

Thanks for fixing the hw sp_.

Still having the same problems as a few previous posters: the pool does not show the full hashrate.

ccminer shows 16 mh average. pool shows the following:



first half is release13, second release14.

[sp_]

What is the reject rate in %. What is the difficulty you mine on. (Is the pool using vardiff?)  
Use a high diff if possible. some pools support to set the diff manually in the password -p d=x.xxx

Are you swithcing between pools? Is the pool paying  PLNS or PROP?

Wich pool?

I have tried with Wafflepool, Yaamp, nicehash, and westhash. Seems to work fine there.

another tip:

High intesity, use high diff.
Low intensity use low diff.

For a 750ti rig try the following parameters:

ccminer.exe -q -r 3 -R 10 -a x13 --no-color -o stratum+tcp://yaamp.com:3633 -u xxx -p xxx

[Handofmidas]

Thanks for the quick reply. I get 100 % accepts (yay!!!). Previous versions gave me an average of maybe 99.9 %. Pool has vardiff and PROP payouts.

I use 2x GTX 970 @ 1500 mhz.

Remember not to have that problem with previous versions, but will doublecheck that later to be sure.

You can try the exe from this thread:

https://bitcointalk.org/index.php?topic=770064.0

Does it report bether hash on the pool?

[tbearhere]

SP just sent you 2 dark coin  thank you   

[Handofmidas]

Allright so just tested release8 for a couple of hours. Pool seems to be allright as it shows approx. normal hashrate there.

ccminer gives 15.2 mh. graph looks better than for release13/14:



Will test now the 1.5.0 release from the other thread.

[Handofmidas]

Started ccminer-30-35-50-52 v1.5.0 now. Getting "Stratum extranonce answer id was not correct!" at statup, but hashes well so far. Need to run a few hours to see pool graph.

[Handofmidas]

Here's my first impression of ccminer 1.5.0. The miner shows 15.2-15.3 mh + occasional hw. Pool shows this:



Left: release14
from 12:00: release8
from 20:30: ccminer 1.5.0

So apparently some of the hash magically disappears.

SP anyway to make the miner/cmd window minimize to the tray
that would be amazing

You can use the start command as in:
start /min ccminer.exe .....

You can also set the priority that way (/low /normal /high, etc).

I started on the merge of tpruvot 1.5.1, but there was so many files and I got lazy. I tested the latest version on compute 3.0 (gtx 650) and it crashed. I will look into it.

When you see commits changing miner.h and structures, its important to do a clean build (make clean on linux or ... Regenerate in VStudio)

I also tried to merge some of your changes, but... for the moment i had weird results on linux.

Shavite seems to be suboptimal on mine... will check that later (Conference today, the whole afternoon)

[sp_]

Your makefile use 128 registers and mine has 80 registers as default, and this will cause big differences.

actually, this should be removed from any makefile or setup (even though I didn't do it myself...), this method of allocating register is deprecated and should be replaced by __launch_bounds__ (I am paraphrasing cuda doc...)

I think the best would be to refork, and just change some of the kernal code.
I will probobly revert BMW to an earlier version. It seems to go faster on 750ti without the new changes  even if it spills more registers and the code is longer. But messuring is abit hard with the boost clock setting. If you push the cards to hard/get hot, they will downclock and loose performance. Different ti cards have different perfomance/voltagate/wattage.
