CCminer(SP-MOD) Modded GPU kernels.

[Grim]

cpu(system): 30 watt
6x750ti: 40-50 watt each

x11: 3000 x 6 = 18000 khash

you lose about 5% to 10% khash due to stale, rejected, new work ...
(don't forget all the fees until you have fiat in your hands)

so in reality its something like:

16500 khash for 300 watt (0.15$)

put these values into what to mine:

best x11: was MINUS 0.25 cent each day
darkcoin: MINUS 0.46 cent each day

Prices are at all time low, but to increase profit you need to mine with a algoswitcher.
And if you live in a cold country like me, you can use the heat to heat your house for free.

Moved the nist5 final test into the skein, removed a kernalcall. Small nist5 boost. 100-200KHASH. (750ti)

ccminer SP_ release 11 with 750ti average (out of 6 cards):

X11: 2870 Khash
X13: 2280 Khash

The Ctrl+C bug is still present.

I also noticed that while mining at NiceHash I now see a green tick below the extranonce subscription column. Previously it was a red cross. Is this related to the optimisation of ccminer?

The hash improvements on X11, X13, Xetc, are due to DJM34, sp_, Epsylon3, and tsiv.  The extranonce compliance and several non-kernel functional improvements are due to Epsylon3; his focus appears to be more on improving control functions.

I am referring to SP_'s release 11 of ccminer. I know the devs who contributed to ccminer... Thanks for the lesson though
DJM34 was the latest dev to have worked and produced a stable release with significant improvements. FYI the very latest improvement of ccminer was done by SP_ (~ +200 Khash) - Still beta as I understand it though.

In order to quit ccminer you can proceed by pressing Ctrl+c. In SP_'s release of ccminer there seems to be a bug where Ctrl+c will lead to the crashing of ccminer.

For some reason ccminer never crashed here after ctrl-c.
This happens:

It does it with me 4 out of 5 times:



Then pressing Y or N produces the same result: ccminer closes

I never EVER had this problem with DJM34's release.

[Epsylon3]

dont press ctrl c else its this kind of small problems i try to fix for my final v1.5.0, i reinstalled ODBG to be able to trace that ... I stop merging SP and Klaus improvements for the moment (except bugs)

I want to make a "final" api 1.2 and a stable base for others, and to be able to correctly compare our changes.. djm34 seems to be back on the scene

It looks like the ostrich putting its head in the ground technic to avoid looking at the problem...

Release 10 works perfectly. No problems whatsoever.

Hashrates (750Ti O/C)
X11: 3000 kH/s
X13: 2320 kH/s
X15: 2000 kH/s

What are your clocks with the 750Ti?

I can get only 2950-2970KH/s with 1246MHz Core / 1580MHz Memory

1210MHz Core / 1600MHz Memory

With 1246MHz Core / 1580MHz Memory.I only get 2780kh/s.Overclocked to 1355mhz can get 3000kh/s.Why?No changes overclocked memory

ERROR RATE:

Since adopting the latest, improved, ccminer, the error rate has gone from 15-20% rejects to less than 1% rejects.  Currently, my rigs run the latest git for 1.5.0, tpruvot's version.  Hash rates have improved significantly, also.   -scryptr

[sp_]

yeah, looks like something has broken in my latest @github. I get some does not validate on the cpu. They are rare @x11. But they are present on standard clocks.. Need to investigate..

I also get a few of the "does not validate on cpu" error statements.  I use tpruvot's 1.5.0-git version.  I did not see a reject statement at the same time.  I was mining x13 on linux.  Very few...overall a lot of progress in the ccminer.       -scryptr

Release 11 of ccminer is crashing by itself. Lost all night of mining. Reverting to DJM34's release of ccminer.

You should run ccminer with a algo switcher tool like this one:

https://bitcointalk.org/index.php?topic=769239.0

Profit will be up by 20% (could be more). And if ccminer crashes, it will restart the miner.

if you are lazy, here is a preconfigured version:

Thanks SP_. In fact I already have Nicehash control tool. Forgot I had it Will use that, thanks.

NVIDIA cards will downclock itself when they get too hot. To reach the maximum speed, make sure that your cards are cold.

You might have to change the voltage as well. Most 750ti cards come without a 6pin power connector, but the cards that have it can be overclocked more.

I've improved some more on 970/980 cards.

My 980 is now doing 9400MHASH with +175 on the clock. The 970 does 7800 MHASH.(+175)
