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

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

SP_ v45-fixed --

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:


--scryptr

What about without the -g parameter?

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

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

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

QUARK and v45--

Quark dropped from 36.6Mh/s to 36.3Mh/s on my 6x750ti FTW rig, but only when running that algo at default intensity and no gputhreads "-g" parameter.  If the gputhreads implementation is fixed properly, the rig will likely mine at a rate over 40Mh/s.

Currently, an AMD 290X struggles to make 5Mh/s per card for Quark with the best sgminer bins available.  I get over 6Mh/s per 750ti.  Pay the piper?       --scryptr

p.s.  It's like getting an invisible 290X that runs on invisible electricity that doesn't cost anything, and the shipping was free, too!  Not to mention that you wouldn't have any extra setup hassles...       --scryptr

I'm getting 17-18 Mh/s on a 980 and 14-15 Mh/s on a 970.

With the latest updated binary, I'm getting 5-7 Mh/s on the 980, not the precompiled release45.

What is your OS?  My 750ti rig is Linux, I compiled the latest update and am getting 36.3 Mh/s.  --scryptr

NEW SP_ FIX --

I just downloaded the git update (30 min old) and compiled.  My Linux rig is back to 36.6Mh/s.       --scryptr

p.s.  I was able to run at 36.6Mh/s with no problems or errors.  I then changed my launch config to include "-g 2" and re-launched.  The rig runs at 36Mh/s with a few "does not validate on CPU" errors.  What may be useful would be to include code that labled the thread as well as the GPU, i.e. "GPU #0 t #1: Geforce 750 Ti, 6100kH/s", or something similar.  The miner could see if all threads are running.  Currently, it appears that the combined total hash rate for all threads on a gpu is being printed to the screen.       --scryptr

wow guys ...

i just woke and reading up on whats been happening ...

checked the test machine on the farm and its crashed using v45 after i left it last night ... its a 5x gigabyte 750ti oc lp with stock clocks under fedora 19 x64 ...

the rest of the farm is running fine - all running v44 ...

i cant wait to get to the office and test the latest release and see if its fixed ...

what would be the best parameters to use ... ill test them anyway - but just thought id ask ... as i see -g 4 -i 10 crashes scryptrs machine and -g2 -i 10 runs but with errors ...

the test machine runs with NO parameters given except for the algo / username / password parameters ...

tanx ...

-g 4 -i 10 works for x11 but you get some "does not validate on the cpu". And I think the miner will crash if you let it run for a while. But the gain is around 25% on the pool. (Testrig with Gtx 960/970/750ti). For quark you probobly need to lower the intensity.

im running it at the moment with 2/3rds of the farm on westhash with qaurk at the moment as a test ... the rest of the 1/3rd is either amd 280x or crashed ...

i havent implemented the -g parameter as i didnt want to push the machines too much ... and im not in the office yet ... did this remotely ...

you can see for yourself how they are performing on westhash if you like ... the bitcoin address is 15umzHXF8NzXA4FywmeFbrDHgL8WcPs3wx to look the performance up ...

https://www.westhash.com/index.jsp?p=miners&a=12&addr=15umzHXF8NzXA4FywmeFbrDHgL8WcPs3wx - is the farm as it stands ... i will reboot the crashed systems when i get back in the next few hours ...

let me know what you think regarding this performance in the 'real' world as opposed to test bench ...

Look on WhirpoolX whith -g 2... +80%

[fenomenhaa]

Thanks for sharing SP, I tried with remote from home but ccminer crashed a lot, will try when at office..

[scryptr]

Look on WhirpoolX whith -g 2... +80%

WHIRLPOOLX --

The Whirlpoolx algo runs at 464.6Mh/s without the gputhreads switch, and over 510Mh/s with "-g 2".  Before, with v44, my six 750ti rig was getting 448Mh/s.       --scryptr

[chrysophylax]

sp - ive reverted back to just using no other parameters as it seems to be quite unstable and crashes a great deal when using combinations ( and singularly ) the -g and -i parameters ...

if you look at the westhash test that is being performed ... it is stable and pretty constant ( apart from the dips from the different coins that get mined by renters ) ...

ill play with the settings a little later tomorrow when i get back into the office ...

tanx for the great work though ...

For whirlpoolx,

The '-d' parameter is broken when using alongside with '-g 2'. So that speed increase only works when using all the cards together, but it can't run individual cards with '-g 2'. And running all the cards together gives a lot lower performance because of overall lower shares.
