CCminer(SP-MOD) Modded GPU kernels.

[chrysophylax]

If anyone is interested in renting Quark hashing power or mining Quark algo for BTC payouts: we added Quark algorithm to NiceHash.com/WestHash.com

Kind regards,
NiceHash

now THAT is news ...

will test with the farm when it comes out of rental ...

I have added a threads per gpu parameter just like in sgminer.  ex: -g 2

Some algos get a boost.

Most impovement on compute 5.2 devices. (960,970,980)

x11 with -g 2 on the 750 ti, the performance is reduced by 0.5MHASH.
The parameter is not always producing higher hashrates.


The stats are reported by each thread, so some more work is needed. (run with -q, so the screen is not flooded with hashrates)


Note that -g 2 will reduce the intensity by one. this can be overridden with the -i parameter.


I will build release 45 now.

1.5.45(sp-MOD) is available here: (18-april-2015)

https://github.com/sp-hash/ccminer/releases/tag/1.5.45

looks like there is a bug in build 45 on some rigs. only 2 of 6 cards are hashing. working on it

[tbearhere]

What is a good difficulty setting for a 6 card 750ti rig on Qubit. Thx

[Nubminer]

here are my numbers with the current build 45

Any suggestions to improve my output would be greatly appreciated

Using this startup

ccminer -i 21 -a x11 -o stratum+tcp://us-east1.dash.miningpoolhub.com:20465 -u user -p d=0.1

using precisionX to bump the GPU to +266 MHz
 
seems to do great rapid acceptance fo the first 7 then after that each line takes awhile like 10 seconds or more

the current compile of 45 actually broke x11 for the systems here sp ...

quark runs nicely though ...

out of memory and core dump errors ... and 44 is fine with those algos though ...

Release 45 gives twice slower speed on qubit with bunch of CPU validation errors:

[sp_]

fixed the bug, and corrected the hashrate statistics. Please try the new version.

Get the latest version and try x11 with -g 4!

the 750ti is peaking at 3200 at standard clocks!

edit:

in benchmark mode, but on the pool I get some does not validate on the cpu...

My 6x750ti Linux rig running Quark at "i 21" and "g 2" is hashing at 39,000+ kh/s, albeit with errors and rate fluctuation:

What about without the -g parameter?

Looks like the -g need some more work. It might not work on all algos..

the -g 4 parameter ( actually -g 2 also ) just doesnt work - it drops just after it starts with no error message that i can see ...

take the -g 4 parameter out - and its all ok with this newer build ... but only on some of the machines in the farm ...

with others - v44 needed to be reinstated due to v45 giving errors with the aforementioned - core dump and memory out errors ...

will get to this tomorrow - as its late here now and sleep awaits ...

tanx again sp ...

Any idea about the expected payouts on yaamp for quark?

-i 10 -g 4 seems to work with the latest on git.

x11 is 25% faster on my 3 card testrig. gtx970,960,750ti

THE "-g 2" FLAG --

It shows a lot of potential.  I was getting 3Mh/s more than my rig was getting before using the flag, until it crashed after about 90 minutes.  I tried "-i 10 -g 4" and it crashed.  I wonder if the 4gb 750ti could handle it better?       --scryptr

p.s.  I think that the 4GB 750ti (STRIX-GTX750TI-DC2OC-4GD5) is not currently in production by ASUS.     --scryptr

[sp_]

X11,x13,x15 +25% on the pool with -g 4 -i 10, but the crash needs to be removed. Donate some beers and i will fix it:) Quark is up less than 10%because it is already running the kernals in paralell.

I sent my 2 bits worth a few seconds ago.  I hope that others also contribute.  The "gputhreads" should be a valuable option for the miner.       --scryptr

p.s. 21Mh/s plus! --

I am getting 21Mh/s on my 6x750ti FTW rig mining X11 with intensity at default and "-g 2".  This is up from a solid 18.9 Mh/s with v44.  Unfortunately, "-i 10 -g 4" crashed on launch.       --scryptr
