SEGMENTATION FAULTS--

I am experiencing occasional segmentation faults on my Linux rigs, mining Quark.  The faults result in a core dump, and require manual restart.  They happen after 36-48hrs of use.  This is with build 861.

Other results, the 750ti rig runs faster, 100kh/s per card, as previously reported.  My 970 rig does not run at 16Mh/s per card, but at 14Mh/s per card, with no overclocking on my Linux box.

My Win 8 rig, mining Lyra2, is stable (so far) with release dot 56.  Release dot 55 would lock up on short notice.  I quit mining Lyra2 for half a week because of this.

Feature Request: When launching CCminer with no intensity, "-i" parameter (default), show default threads in launch display as (DEFAULT), as if they had been specified.  Should be simple to implement.  I am having difficulty adjusting intensity with each new build and algo.  Donation is promised.

Thank You!       --scryptr

I am getting this error with new version:

Code:

Cuda error in func 'scanhash_quark' at line 177 : cannot set while device is act
ive in this process.

I second this request! I'm also having issues with crashing while mining neoscrypt. It'll work fine only if i start mining after a fresh boot, but if the computer has been running for any length of time or i'm switching from another algo it crashes out shortly after starting (about long enough for me to read initial output)

I think there is a bug in my getwork implementation of neoscrypt.

Code:

static bool work_decode(const json_t *val, struct work *work)
{
	int data_size, midstate_size;
	switch (opt_algo) {
	case ALGO_NEO:
		data_size = 84;
		break;

The other forks use a data_size of 80

Release 56 has finally made be break 100 mh/s on quark. Virtual beers for everyone!

The 980ti is looking strong.

[go6ooo1212]

How's the power consumption on 980ti , compared to 970 ?

[fenomenhaa]

From my side +50-65 k/hash for 750Ti's and 200k/hash for 970  with built 56. Good work sp... )))

It appears the miner continues to load the gpus when the network is down. Is this the expected behavior?

No. please help me fix it.

More is coming... If you want a higher hashrate, Please donate some beers.

7.05 MHASH per 750ti.

With djm34's changes we perhaps get 7,5MHASH per 750ti ??

Remember. People who donatate more than 0.1 BTC will recieve my private spreadcoinminer with sourcecode (linux compatible)

ccminer spreadcoin (sp-mod) release 9 is (10-20)% faster than the opensource version

ccminger.....sounds kinda dirty

Never tried spreadcoin ,is it compatiable with windows too? All my rigs based on windows.. ).What about spreadcoin is it more profiatble then quark or neoscyrpt? About private miner pls inform me when you releaised !!donation. on the way,thanks for your hard work..!!

No. please help me fix it.

Glad to do it. Please point me to the piece of code that does the check and I can look into it.
Some more info: ubuntu 15.04, network card and link are up but the connection to the gateway is down.
From the power meter I can see a slight reduction in power usage but the output, while including the connection issues, it also includes the normal hashing of the cards.

It is profitable when few are mining it. The windows exe is included, as well as the sourcecode.

Most coins are more profitable than the multipools/rentalsites if you mine direcly. Being able to switch between algos, will make you make a profit in the long run.

Spreadcoin can only be solomined.

Aliman,

Your 980ti is beating the Titan-X

take a look at this commit:

From the tpruvot branch: prevent gpu scans before a job is recieved:

https://github.com/sp-hash/ccminer/commit/8f7f6dfd8f627fefd2f5a2fbda4612827588ef02

This will prevent the miner to start if no connection is there in the startup. But if the connection has timed out, there is no code that stops the gpu to mine

@sp_ , how does the c11 algo compare with quark algo power-wise?  safe to keep the 750ti overclocked ~ +100 MHz?

c11 should be equal to x11 power-wise

maybe we could set a global flag when, say, 3 shares submission fails, then add that flag to the check you outlined.
