CCminer(SP-MOD) Modded GPU kernels.

[chrysophylax]

I fixed the compiler errors. The change in skein hash reduced the performance in quark. I will modify it.

looks like the last groestl change broke the hash. will submit a fix.

just for groestl? this is what im getting for x11 also mate ...

so maybe broke it for all?

this commit "restore performance quark" https://github.com/sp-hash/ccminer/commit/9b94e71d6764cf8176d5b5321585cc28a55ce22e
seems to broke quark on gtx750

[sp_]

Get the latest. Build 38 should work now.

Groestl is used in quark and x11 etc.

1.5.38(sp-MOD) is available here: (8-feb-2015)

[rednoW]

Thanx for new release! It works. quark performance is nearly the same with r36 abd r37.
One moment - i don't now if it worth to point at - x13 don't work on default settings on Hamsterpool.
It works fine on Yaamp and Nicehash though ... )))

compiles and runs really well sp ...

will test on the rest of the farm tomorrow ...

yes. for compute 5.0 (750,750ti) the speed is the same, but for compute 5.2 much faster. release37 had a drop in the speed for 960,970,980 cards.

I am getting many "result does not validate on cpu" errors in various algos.  However, shares are still accepted.  In setting up auto-switching yaamp by using the "-r 0" round-robin flag on my Windows commandline, I have been seeing results on more algos than I usually mine.  The version running is v38, on a GTX 960.           --scryptr   

[sp_]

Wich algos?

[scryptr]

Wich algos?

Was?  Ins algos x11,x13,x14, und fresh.  Vielleicht mehr...

Aber, es tut mir leid, ins Englisch, die worte "which" ein "h" haben.       --scryptr

[go6ooo1212]

I saw same error on X15 today with r38

YAAMP ROUND-ROBIN CONFIGURATION--

The following is a working Windows Batch File for a GTX 960 using the yaamp auto-switch.  The "-r 0" flag allows yaamp to cycle through algorithms until the high-paying algorithm is served up.  The long "password" should be comma separated and have no spaces except immediately after the "-p".  Each line is broken by the formatting process on this blog after the "-p" password flag.  I inserted 1 extra blank line between each 1-line command statement for clarity.

There is no such simple solution on Linux, primarily because BASH does not have a goto command.  Save this text as "looper.bat".  Code follows:

:loop

ccminer.exe -r 0 -a x11 -o stratum+tcp://yaamp.com:3533 -u name -p x11=5.4,x13=4.2,x14=4.1,x15=3.6,quark=9.8,lyra2=0.7,fresh=6.1

ccminer.exe -r 0 -a x14   -o stratum+tcp://yaamp.com:3933 -u name -p x11=5.4,x13=4.2,x14=4.1,x15=3.6,quark=9.8,lyra2=0.7,fresh=6.1

Has anyone got build instructions  from source on Windows 8 ?

Compiling on Windows (at least, most software - that is, software that doesn't come with MSVC project files) is not easy.

I know, i already compiled a lot on Windows but this one seems to have some strange issues...

Works on 750ti. You can remove compute 5.2 in the projectfile and try to recompile until I find out whats wrong. Or revert to an earlier build

Has anyone got build instructions  from source on Windows 8 ?

Install Visual Studio Express 2013 for Windows Desktop
Install Nvidia CUDA 6.5 Toolkit
Download the ccminer source code
Open the ccminer.sln file
Make sure the compiler is set to "release" and "Win32"
Rebuild solution

Then you should see the ccminer.exe in the release folder

The sha256 algo implementation might come in handy because a coin with modified sha256 is coming from earlz no less:

And you know what, its the same since XP and works also on Windows 10 ! :p
