CCminer(SP-MOD) Modded GPU kernels.

[sp_]

Here is decred sp-mod decred #8 With max overclocking. I use -i 31,9 on the 980ti and -i 29 on the 750ti.



Here is the sourcecode of the sp-mod #4:

I decided to test a version of the miner from Alexis78 on Decred
Again, the core of 960 and 970 graphics cards overclocked to 200MHZ.
Adjust the intensity taken from the BAT versions from SP
I compared the version Decred8Vcash6 vs Alexis78 latest from the git repository
Frankly, the results surprised me. Alexis78 great job! Your miner free, and the rate paid from SP!
SP - again there is work to do!
Alexis78 results :

SP_Decred8Vcash6

The competition continues

The competition continues

hehe. Why do you mine decred on the 960 and the 970. Pretty stupid when you can double Your profit With etherum or quark.
What intensities are you using?


The cryptomining blog is only getting  2394 MHS on the 980ti. (only 30% faster than the gtx 970 With 66% more cuda cores.) Why is Your build so much faster? Can you download their binaries please and test please.

[Velgelm]

Eth gives me (0.4 eth) or 3.9$ day(diff grow) 970 doing 18Mh 960 do 10Mh
Dcr gives me ~3-3.2 dcr or ~ 4.0-4.7$ (diff down) 970 do 1850Mh 960 do 1120Mh

i compiled lastest git version on my PC and run with bat from your miner configs

I don't include the miner config in my releases. What does the bat look like.

[Velgelm]

960 ccminer -d 1 -i 26.9 -a decred --cpu-priority 1
970 ccminer -d 0 -i 28.9 -a decred --cpu-priority 2
this intensy gives better results

[sp_]

why don't you compile this:

https://github.com/sp-hash/ccminer/commit/3a726d90efd528ed386407bbd5b223583d80b378

copy the decred_ok.cu to decred.cu in the algo256 folder and rebuild.

And use -i 29.6 as intensity. It is "faster"

"faster" at the command line, slower at the pool ;-)

"faster" at the command line, slower at the pool ;-)

But in version #8 I have fixed the bug, and the hashrate is the same on the pool.

[sp_]

960 ccminer -d 1 -i 26.9 -a decred --cpu-priority 1
970 ccminer -d 0 -i 28.9 -a decred --cpu-priority 2
this intensy gives better results

If you remove the intensity parameter and run both the exe files without the -i my miner is much faster. Basicly you reduce the speed of my kernal by putting on an intensity brake. you should also remove the --cpu-priority parameter. My VCASH mod is only using 25 registers(little GPU Resources), and need a high intensity and overclock. The right 970 card can run stable at a 1600MHZ core for weeks.

[sp_]

decred #8 is using 29 registers

here is the speed with a proper launch configuration.

[tbearhere]

Same speed as quark... I just noticed that With sp private #5. 

[Velgelm]

what is the proper launch configuration. ?

[sp_]

Same speed as quark... I just noticed that With sp private #5.  

For sp-private #5 quark use -i 25 on the 980ti. The default is -i 24

[sp_]

what is the proper launch configuration. ?

Boost the coreclock to 1600MHZ, reduce the memory clock (500mhz). And run without any parameters.

[Velgelm]

SP_Decred8Vcash6 - without -I and --cpu-priority parameters :


Alexis78 lastest git - without -I and --cpu-priority parameters :


I understand that by default your miner faster. But if you set the settings manually the same for both miners your miner is slightly faster, and then slower than free

[sp_]

Now you should set the clock to 1600MHZ +100 more. (for a 6% boost). It should work fine in my miner, but perhaps crash in his miner.

[Velgelm]

In my version cards MSI gaming I can't lower the memory frequency, it is fixed on 3005Mhz
