CCminer(SP-MOD) Modded GPU kernels.

[sp_]

1.5.44(sp-MOD) is available here: (30-mar-2015)

https://github.com/sp-hash/ccminer/releases/tag/1.5.44


buildt with compute 5.2 and 5.0

-faster x15
-faster x11,x13,x14,x17
-faster lyra2,quark

.old whirlpool coin support is removed becasue of incompabitility with the x15 improvement. (to lazy to make a fix for a dead coin)




The sourcecode is available here:

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

[Epsylon3]

you are right, will remove it also in 1.7

[tbearhere]

Can't compile 1.6.0  need zf5 algo.

sp did you get my pm?

[sp_]

What values did you set that gave you 300 mh/s on the 980?

You probobly need to move some constants from the constant memory to the intruction cache. Don't remember. Ask wolf0

sp did you get my pm?

Yes. I might do it when I reach Laos

comparing v43 vs. v44 for my gtx750(non-ti) (windows binaries from github)
x15: 1966 vs 1976
x13: 2272 vs 2270
x11: 2886 vs 2883
quark: 5700 vs 5660
qubit: 4418 vs 4419 (with drops)
lyra: 882 vs 881

So, only x15 gain for me

He says he has no idea as he doesn't do Nvidia anymore.

Why didn't you just update github with that increase?

Try to reduce the launchbound in Shabal from 320 to 256. If you have time revert some of the change sets to find the one that slows down.

What is your hashrate with the current miner? ( Max overclock)

[SS2006]

unfortunately with the latest release intensity 21 now crashes my cards (GPU GTX 970, two of them in SLI)
previously it was fine, now I am setting it to 20 meanwhile

296-297 mh/s @ 1624 Mhz

There are to many changes for me to test ((
Did you mean shavite to change TPB from 320 to 256? (ccminer-windows\x11\cuda_x11_shavite512.cu)

Yes. The 750 has 512 shaders while the 750ti has 620. A threadcount of 320 was faster on the ti but proboby not on the 750
And the 980(?)

[rednoW]

I tried changing 320 to 256 in shavite ... no good ((
I have manual set intensity in batch files e.g. - I 19.3 tuned once some time ago ... hope it doesn't interfere performance of new builds ...

I read the last few pages, but I didn't see:
What hashrate does a Nvidia 750Ti card make on X11 with the latest miner/binaries?
With what settings, and possibly at what consumption (watts)?

Thank you

Thank you

standard settings with stock clocks and 64 bit compile using sp's latest we get around 2840KH using x11 ...

thats per card - gigabyte 750ti oc lp ... and they consume around the 60W mark per card ...

Your junior 750 is beating some 750ti's on standard clocks.
I think it's time to implement a command line switch for the gpu-memspeed and the gpu-core clock. Some of the algorithms needs a good memoryspeed/corespeed factor, and some of the cards are not configured optimal. I had a quick look and found support in the NVIDIA api to adjust the clocks.. Will have a look when I get back from my vacation..

In the north east thailand:

1 hour of Thai-massage costs        0.012641 BTC
1 bottle of 40% thai whiskey costs 0,0088487 BTC
1 noudlesoup meal with meat and clean ice water in the resturant costs 0,0029495  BTC

nice ...

would be ideal if we could manipulate the clocks ( mem and core ) from the commandline ...

sounds very cheap over there ... and very nice ...

might even be able to buy property too with btc ... i wonder ...

For reference, I get 50W per card with TDP increased BIOS and +140 Mhz on the core on the same cards on gold PSU and hashing at 3166 kh/s. I always use 32 bit builds.

Suddenly, I want to go to Thailand. I'm afraid I might stay there though.
