CCminer(SP-MOD) Modded GPU kernels.

[fenomenhaa]

Without any parameter 5*750Ti rig QUARK 30600 increase to 32050.

Time to donate some satoshis to the developers ?

More free hash is comming..

Sure,soon i'll donate again ))). 5*750Ti 32050  from the wall 395W with amd underclock apu cpu ))) .. i have another 15 280x but they are so bad in quark )) or i don't know latest kernels )))) At this time i changed all my rigs to x13 ENC and BT x11 ...fresh coins and and for now great earnings )).

1.5.46(sp-MOD) is available here: (25-april-2015)

https://github.com/sp-hash/ccminer/releases/tag/1.5.46

The sourcecode is available here:

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


-Added scrypt and scrypt-n from the motherbranch/cudaminer
-Fixed the hash with the -g parameter (quark, x11,x13,x14,x15,x17)
-Optimized blake(faster quark, x11,x13,x14,x15,x17)

Big thanks to Klaus_t( who fixed the broken hash) https://github.com/KlausT/ccminer
Also thanks to tvpruvot who merged the scrypt kernals from cudaminer https://github.com/tpruvot/ccminer

and the betatesters at bitcointalk.org

with what settings? ...

waking up not too long ago and reading back on all this has now got us into overdrive ...

heading to the office and testing the latest build in the next few hours ...

will update here soon guys ...

what is the 'best' commandline paramters for the 750ti oc lp? ...

-g 3 -i 22 ? ... or just run single threaded? ...

#crysx

[DragonSlayer]

Pretty sure -g not working when using -d.

chrysophylax,

You need to get some remote program on those rigs to work from home also.

Didn't tried many settings yet, it's with default settings, single threat and without intensity,It's almost morning in my city ))). Need to sleep )) Tomorrow will try with g and i parameter.

[AliMan]

Yea everything without the -i is giving a decent boost, at least on quark. GTX 980 was first doing 17,900 kh/s - 18,200 kh/s, now it's like 19,200 kh/s - 19,280 kh/s.

stock clocks?

Hi all, for myself : 1.5.46 sp

does not validate on cpu still there.
-g 1,2,3,4 don't seem to work with gtx970X2 (maybe i do the wrong thing (not in sli))
i get better performence without -i (approx 8000 khash/s each)

ccminer -o stratum+tcp://us-east.multipool.us:11111 -p x -u xxx.xxx

At least, thanks everything work without those parameter and i get decent hash on x11 !!

if you are using -g WITH x11 ... then you will still get issues ... we still do also ...

-g parameter works well with quark - but find that there are major issues with x11 ...

-i parameter on x11 works very well - you just got to find the max that you can push the intensity of your cards ...

our gigabyte 750ti oc lp cards can be pushed to -i 20.5 stable ... -i 20.6 still runs but not so stable ... anything more than -i 20.6 and ccminer crashes ...

we will be testing v46 with quark ( and various settings ) later today on westhash ... then possibly on yaamp ...

Run it without launchparameters. The -g parameter still needs some work..

-g 2,2,2,1 is not supported.
-g 2 will create 2 threads on every gpu in the rig.
The -d parameter with the -g should be supported, but there might be issues.

With the -g parameter, only quark and x11,x13,x15,x17 is working.
whirlpoolx, skein, qubit etc will give "does not validate errors".

So run without any launch parameter. Boost in most algos.

All my rigs have been running release 46 stable for 6 hours now (no launch parameters). The boost on the pool is significant

[jjjordan]

Yeah, when I start quark mining with -g my speed is less (28M for 2x970), compared to 31M when starting without any settings (only -r and -R). release 46

chrysophylax,

You need to get some remote program on those rigs to work from home also.

tanx antonio - appreciate that ... but they ( the servers and worker machines in the farm ) are linux systems ( fedora 19 x64 for the workers and scientific linux ( rhel based ) for the servers ) so ssh console is all i need with them ...

for some reason - the internet link that i have for the farm was down - and the internet link for the servers was down also ... hence why i couldnt log in to either ...

when the farm link is down - they have a failover / fall back with the second internet link - as the farm is a subset of the network ...

it doesnt need any other software apart from ssh - which is stock standard with all linux distros ... the home machine is a windows ( yup - the only one ) machine as i need it to test and support with from here ... its THIS home machine that needs an app - and 'putty' does just fine to log in via ssh ... when i need anything else - like an x-server on here within windows - i just run cygwin ... ...

anyway - it seems as the dual-broadband router might be at fault here ... had it for years and its served the network VERY well ... linksys ( now owned by cisco ) rv082 - the earlier version ...

will have to buy ( ebay ) a new one soon i think ...

in any case ... have changed the systems over now to v46 x11 and one testing on quark ...

quark ... -g 3 -i 22 is still rocky and unstable ... no chance x11 is working with -g parameter for some reason - only have it running intensity -i 20.5 ...

restesting quark on the small machine without any parameters initially then with intensity settings ... might start at -i 22 with -g and work my way up from there ...

Release 46 doesn't perform well on my machine, (GTX 970 / Win 8.1 x64) mining Quark algo, no settings.

The power consumption is a sawtooth waveform. It loads the card to ~120% (overclocked) and then down to basically 0%. Over and over. Up down, up down, up down.

Mining XMR the power consumption might fluctuate a little, and might not load all the way near 100%, but it is at least never below 60%.

I don't know why this happens and I know sp_ works hard on it and most you guys are on linux, but it sucks for me.

It maybe you card/driver problem. If power consumption goes over 100% TDP then card goes to some low power mode. And again, and again, and again.
Try to decrease clocks or maybe you will need to flash bios with higher TDP.
I did it on my gtx750 cause by default its TDP was only 38W and it went "resting" on every serious load.

exactly ...

unless there is some serious flaws in the programming ( which doesnt look like there is at all ) then it just may be the clocks ...

on our farm - there is NO overclock - all stock - on all machines ...

this way - if there is such an anomaly like what you are experiencing - it will be much easier to diagnose ...

these nvidia cards are all built in with 'safety' cutouts so as explained - unless you are willing to flash the firmware of the cards and play with the settings - then mine with ONLY stock settings with NO oc or intensity parameters and see how it goes ...

if all is well - start to play with the settings and see what the optimal settings are for your card ...

if all is not well - and you have checked ALL the system settings and components - then it may be a reason to check the card ...

always start stock - and go from there ...

Good suggestions, but I should note that it does the same thing on stock clocks.

And I can use release 44 with no issues but I WANT THE BOOST!

But, I will look further into it, and I may flash the BIOS, but I never had to with my 750Ti, so I don't want to unless I need to.

Try to decrease clocks significantly below standard. If the problem remains then this is not a clock/power consumption problem.

P.S. Did you try benchmark mode? Is situation the same?

try to run with -i 22 or less. Less power consumption with lower intensity. Is your PSU good enough?

[ryen123]

This is the best release so far. Single thread on 750Ti is rock solid at 6766 kh/s [quark], showing the same and higher accepted hashrate stats on westhash. With -g 4 -i 22 comes close to single thread performance but not consistent.
