CCminer(SP-MOD) Modded GPU kernels.

SP, before you build 46. I tested and built the recent update and am getting really low values on quark, as I've only tested that with different -i values.

[arpika]

With the latest build hashrate is really high according to ccminer. (quark algo, yaamp, linux, 970/750ti rig, 50 and 52 capability)
Yaamp reports similar hashrate first but for a longer period the hashrate is lower compared to the eg. 43 version.
Hashrate reported by yaamp is lower even without -g parameter but with -g the difference is more significant. I tried with -g 3, -g 4, without intensity setting and with -i 22, I increased difficulty but the result was same.

COMMIT 729--

I cloned git on my two rigs, compiled, and began mining Quark about 4 hours ago.  The 6x750ti FTW rig continues to report 50-60Mh/s, and the 2x970 FTW+ rig reports 38-42Mh/s.  The acceptance rates are about 98% for the 750ti rig, and 97% for the 970 rig.  There are very few errors.  Long streams of card hash rates are interspersed with accepted hash (yay!!!) messages.  However, the pool reports slightly lower hash levels total.

Prior to the test of build 729, I was mining with build 724, single-threaded, with the intensities that I reported yesterday.  Currently, the high intensity setting, single threaded, is resulting in better hash reported poolside.  Mining with "-g 4", my machines report 90Mh/s+ total hash rate, the pool reports about 70-75Mh/s.  Mining single-threaded, my machines report 75-80Mh/s, the pool reports about 75Mh/s, sometimes less.

With 4 threads, the high hash rate accepts (yay!!!) messages are less frequent, a large amount of thread rate data is displayed between accepts.  The 750ti thread rate values range between 6-12Mh/s.  The 970 thread rate data ranges between 11-40Mh/s.      

The configuration string for the 2x970 FTW+ rig included "-g 4 -i 23" for performance.  The configuration string for the 6x750ti FTW rig included "-g 4 -i 22" for performance.  These were the highest working intensity values that I could quickly find for either rig.

Yes, with one thread the latest quark has dropped 1mhash. I am fixing it now.

What the best settings -g and -i for single 750 ti?

What the best settings -g and -i for single 750 ti?

Do you mean Quark?
My guess is ccminer by sp_ release 43 (thai build ) without any -g or -i parameters. Or maximum -i that doesn't crash
I have no faith in multiple gpu threads ...


For other algos use Release 44 or 45 without -g with manually tuned -i or default -i

What the best settings -g and -i for single 750 ti?

Single-threaded I have been able to use "-i 23.5" for Quark.  Multi-threaded, "-g 2 -i 23" gives reasonable hash rates without crashing, this is with build 729.  The multi-threaded rates currently swing a bit at launch, and then settle in at a reasonable rate similar to single threaded performance.  In about 30 minutes, my rigs will have run for 4 hours with "-g 2 -i 23", and I will go to single-threaded for another 4 hours.  With build 729, I will have compared "-g 4 -i 23", "-g 2 -i 23", and "-i 23" (single threaded) about 4-5 hours from now.  

Currently, build 724 gives me the best overall hash rate, local and poolside, when run single-threaded with "-i 23.5" for the 750ti and "-i 23" for my 970s.  Different model 750ti cards have different capacities.  A few were made with 1 gig memory, most with 2 gigs, and there is a rumored 4 gig ASUS 750ti in the works.  The power and factory clocks vary, also.

p.s. build/commit 724 was v45, earlier yesterday, prior to the "...does not validate on CPU" fix based on KlausT's work.

all I can say is WOW.
Just built and run quark without any parameters.
Hashrate goes from R43 record 5717 to stable 5810.
GPU memory usage raised from 112mb to 383mb
Power consumption is also raised up to 63% TDP from max 58% of release 43. (gtx 750@1480/1570)
Just need some time to check pool hashrate

BASELINE BUILD 730--

I cloned from git and compiled build 730.  I am currently running at baseline (no "-g" or "-i" or other performance flags set) and my 6x750ti FTW rig is mining Quark at 38.1Mh/s, with the 2x970 FTW+ rig running at 29.75Mh/s.  This is superior to the results obtained earlier today with build 729, both 2- threaded and 4-threaded.  There are no errors or fluctuations.

I curtailed any testing on build 729.  My copy is backed-up.  After 4 hours with build 730, I plan on finding the maximum "-i" parameter for a single thread, then testing 2-threaded and 4-threaded mining at maximum intensity.       --scryptr

P.S.  Both of my rigs are delivering "Found nonce $A1B2C3D4" messages in the thread hash reports.  The 8-digit string is any random hexadecimal number that satisfies the block, I suppose.  They don't seem to be errors...       --scryptr

P.P.S.  My poolside hashrate is currently 116Mh/s, more than is being indicated locally on my rigs (about 77.5Mh/s, total, and including the 960 SSC on my work computer).       --scryptr

P.P.P.S.  The rigs are still at 100% accepts after both have more than 250 accepts!       --scryptr

Y.A.P.S. The rigs are still at 100% accepts after more than 500 accepts each!         --scryptr

building release 46 now.. Thanks for testing guys.

After I added scrypt, building takes forever. The exefile is also much bigger. The scrypt kernals are too big. I think I need to shrink and optimize.

GTX 960 SSC--

The 960 card in my Win 7 x64 system is running at 9.98Mh/s with Windows release v46.  It is running single-threaded, with "-i 23.7".  It ran at 9.9Mh/s with no "-i" parameter set, default intensity, when I first started it with v46.  Many times thread hash reports are just over 10Mh/s.  Accepts are at 9.98Mh/s.  This is about 500kh/s better than prior best results with v44 and v45.

Defaults are set to -i 23 for compute 5.2 devices(960,970,980..)
and -i 22 for compute 5.0 devices(750,750ti..)

23 was faster on my testrig on the 750ti, but it crashed after some hours.

1000 ACCEPTS BUILD 730--

After at least 1000 accepts on both rigs, (1000/1005, 6x750ti FTW, 99.5% and 10053/1055, 99.81% 2x970 FTW+), and more than 4 hours, I am going to upgrade to v46 on all cards.  Currently, my rigs are under reported at 66.7Mh/s at the pool, but have been over reported in the recent past.  Poolside rates flucuate.

I am going to upgrade to the release version, v46.       --scryptr
