CCminer(SP-MOD) Modded GPU kernels.

sp ...

it compiled after i changed the filenames as per your instruction in the Makefile.am file - though the second file required the .cu extension ...

ive now moved the compiled spreadminer to one of the production systems for testing ...

there is an improvement in performance - though not as much as i would have hoped using stock clocks per gpu - but nonetheless - an improvement in comparison to tsivs miner ...

below are the output of both the currently running spreadminer-tsiv and also the newly compiled spreadminer-sph both using the -x 20 parameter ( they are machines exactly the same specs ) ...

so as you can see there is a marked difference between the two workers ...

ill now propagate the latest spreadminer-sph across the farm and see how they perform overnight ...

tanx again sp ... this will help a great deal overall ...

#crysx

I run without launchparameter (default is set to -x 5 on the 750ti). The 750ti will reduce the clockspeed if the cards get too hot. Lower intensity might be bether in the long run. I also think that 32bit builds will be faster. My windows compile (x86) is performing much bether.

so as you can see there is a marked difference between the two workers ...
ill now propagate the latest spreadminer-sph across the farm and see how they perform overnight ...
tanx again sp ... this will help a great deal overall ...
#crysx

I run with -x 5. The 750ti will reduce the clockspeed if the cards get too hot. Lower intensity might be bether in the long run. I also think that 32bit builds will be faster. My windows compile (x86) is performing much bether.

ive changed the parameter to -x 5 and it seems to perform about the same ... so ill keep it at that ...

as for the x32 builds ... ill have to test that another day - as ill setup a x32 machine ( fedora 19 or 20 x32 ) and build it from a fully 32bit platform ...

what other commandline parameters do you think would benefit the hashrate / processing? ...

btw - just a small thing - but the title still says spreadminer 5

#crysx

Different intensity  parameters for different cards.

For the 750ti -x parameters should be a multiple of 5
for the 750, 960,980  -x paramameter should be a multiple of 8
and the 970 -x parameter should be a multiple of 13

tanx sp ... that is something that will be kept in the knowledgebase ...

i edited earlier - which i missed obviously - but the title of spreadminer is still at version 5 ...

thats not a big thing at all - but i thought you might want to know ...

btw - just a small thing - but the title still says spreadminer 5

yeah, forgot to change it. The bottleneck in the spreadcoin hash is the cuda_sha256.cu function that iterates a 200000 element table.
I moved the table to a texture and got a small boost, but it broke the hash.
I will release a version 8 with higher speed soon.

sounds like a great deal of work ...

if version 8 can run faster - then wouldnt that be a 'leaner' miner? ...

would be nice to see if there was a leap in hashrate ...

I have started on the cryptonight core now. But tsivs compiled version seems to crash on cuda 6.5 win8. Anyone have any tips ?
I tried different -l parameters but doesn't seem to work

never used it on win, on linux -l 8x60 was my always working launch config with a 750ti.

The hashrate is too high and the driver is crashing..

Seems to work now, I fixed a bug in benchmark mode

8x60 crashes

8x30 works.

but it should work without launch config. the default tsiv used were quite conservative.

[myagui]

I believe you just need to disable the driver checking (or make the check interval larger):
https://msdn.microsoft.com/en-us/library/windows/hardware/ff569918%28v=vs.85%29.aspx

My working setup was to just set TdrLevel off (zero).
A more conservative launch value is 8x30 (though 8x60 does work best for me).

Cheers!

If I remember right there were some strange issues with windows 8 & 8.1 and tsiv's cryptonight miner. Had to use 8x30, higher values and it crashed. On windows 7 8x60 worked and was faster too.

[sp_]

I get 200-227H/s on a standard clocked 750ti with 8x30.  Latest version of the sourcecode

What hashrates did you get?

Yes I am on windows 8.

What hashrates did you get?

I have about 265~285 h/s with factory overclocked 750 TI and using 8x60.
Hashrate fluctuates quite a bit for me.

240-245 overclocked cards. 8x30 and windows 8.1.

The crash is because windows tries to allocate a big chunk of memory. I am trying to build in x64 now to check if it works with -l 8x60

edit: Crashed with a bluescreen. -l 8x30 works and the speed is around 5h/s slower than the 32bit build

Increasing the delay on the driver check (or disabling it entirely) as I posted about above, allows for the memory allocation to succeed without crashing. I have best performance with the x86 build as well.

I managed to get 20KHASH pretty easy, and the hashrate is more stable.

Now the miner is running stable at 232.5-236 on standard clocks. up from 200-224 (8x30)
