I have one of gigabyte's super overclocked and without any additional oc it humms at 1350 gig hertz. That's where I find nvidia's sweet spot on all types of gigabyte's 750 ti's even the standard or low clocked by them. I set it to 1350 gig hertz.

Is that the actual clock speed or the setting in what ever program you use to OC?

The actual clock speed CapnBDL. No oc.

Thx...that's what I thought...I OC to 1400. Can't go higher without a crash.

See this is where I think a baseline reference is needed. Manufactures supply cards that they themselves have OCd beyond what Nvidia states as the reference design (which is 1020Mhz in the case of the 750 Ti). I went and took a look at the gigabyte website and compared all of their various 750 Ti models, none of them are clocked at 1350Mhz (neither base nor boost).

So, without further info and clarification, I can only assume the card has been OCd further from listed on MFG's page, or you have a model that is no longer listed.

Hi guys, not sure where to post this.

I've published an issue on github about it : https://github.com/cbuchner1/ccminer/issues/31

1.5.53(sp-mod) does not submit anything.

I have tried several pools, it doesnt say reject, it just says nothing.

It goes on and on showing me a hashrate, but nothing is ever submitted.

I've googled this a lot, but to no avail. Anyone had this issue before ?

I'm on RedHat, CUDA 7.0, nVidia GRID K2, compute 3.0 (is support for 3.0 dropped in this version ?)

Code:

@ Taiko3615:

This is SP_'s fork, not cbuchner1 (you posted an issue on the wrong ccminer fork @ github).
This fork is optimized for compute 5.0+ cards, compute 3.0 will probably not work for most algos, if it works at all.
Cuda 7.0 is known to break some algos, and is generally slower on the ones that do work.

Your best bet, if you really only have that hardware/cuda setup available, would be Epsylon3's fork. As I understand, Epsylon3 has been working on integrating Cuda 7.0, and also, his fork is generally more inclusive of older cards.
https://github.com/tpruvot/ccminer/ 

Good luck!

Hi guys, not sure where to post this.

I have tried several pools, it doesnt say reject, it just says nothing.

It goes on and on showing me a hashrate, but nothing is ever submitted.

I've googled this a lot, but to no avail. Anyone had this issue before ?

I'm on RedHat, CUDA 7.0, nVidia GRID K2, compute 3.0 (is support for 3.0 dropped in this version ?)

You need to enable compute 3.0 in  Makefile.am. There is some discussion on how to do this earlier
in this thread. I have no 3.0 cards but I can confirm it works on 3.5. Also stick with cuda 6.5 for now.

FYI this isn't the kind of problem that warrants a ticket. Besides the fact that you ticketed the wrong
fork SP is focussed on 5.0 and above and unlikely to respond to a problem affecting other compute
versions, even a legitimate problem.

However, you're in the right place now. Be sure to post your results.

Edit: Ooops, cuda 6.5 not available on Redhat 7

[Taiko3615]

Thanks !!! the tpruvot one did work !

The first time I tried to compile it, it didn't work, here's what I did to have it running
1-I take a realease version, not the repo directly
2- I just had to edit the Makefile.am and uncomment the line " nvcc_ARCH += -gencode=arch=compute_30,code=\"sm_30,compute_30\" "
3-
export CUDA_HOME=/usr/local/cuda-7.0
export LD_LIBRARY_PATH=${CUDA_HOME}/lib64
PATH=${CUDA_HOME}/bin:${PATH}

Then it worked just fine !

First try to use cuda 6.5 until we figure out how to use it 
Second yes these version doesn't support compute 3.0 (I haven't seen either what you we mining exactly...)
epsylon3 has a version with compute 3.0 support

Some sad things about ccminer.
I used to test my "legendary" oc'ed gtx750 in different algo's on nicehash and yaamp.
Let's talk only about quark and nicehash as they are still look good ))

My ccminer shown hashrate was ~6000khs. But in nicehash on long run average hashrate was smoothly fluctuating between only 5400 and 5900. Very seldom it goes up to 6000 and very soon drops to ~5500 again. I talk about Average speed nicehash, not about Speed accepted.
I thought it's ok due to some network losses or something like that.

But now i temporary grab 2 radeon 7950 and put it instead of my gtx750 in the same machine. With optimized ccminer 5.1.1 (russian, available from cryptomining blog) I see about 21-21.5mhs in sgminer window. I use xintensity 512 that is known to provide good hashrate on pool ...
And nicehash now shows Average speed 21.5-22.3mhs. This is even better then miner shows!

So this situation is not in favor of nvidia and sp_'s ccminer. I know that nvidia and sp_'s ccminer are better in terms of perf per watt ... but this amd cards are so dirt cheap now ... and give nice absolute performance with more "honest" hashrate in miner ...

If you pay more then you make in electricity it doesn't matter what it hashes at. AMD cards use about 50% more electricity. Hope you have cheap $/kwh

[smolen]

DRM is more or less a time-lock - the more work you put into it, the longer you get before it's useless.

Looking at old blockchains I'm almost sure that Quark version of Smelter got hacked. Well, time to do licensing server.

Just buys you a little more time before the call to the server and the check is NOP'd out. Ticktock.

I'm looking at eldentyrell's trick with signcrypton; it (hopefully) should give some time.

Encryption, authentication, verification, and updates... I guess developers actually have to try at what they're doing and make a actual program. Maybe even make a company. You know, take shit seriously.

There is and never will be a 100% effective DRM. You just make it not worth someones time to break it. That means fair pricing (1-2% mining fee) for a fair product. In addition to this people DO actually buy software and use legal software, even around here. This is why software companies still exist in real life, even though pirated copies are so easy to come by.


Also all algos are in the shitter right now for some reason.

What you are asking is ridiculous (as usual).
If we were to make such program/company considering the work involved, I would not price it below 15btc per copy (which actually isn't bad  )
Would you buy it ? Guess not
And "fair mining" in the 1%-2% yeah right   fee rather 5~15% you are kinda cheap...

Stop asking people to make stuff, you would never buy unless it is free

regarding the miner with dev fee I did for vnl, I think it works however people released very fast an open-sourced one and since it wasn't the fastest... 
But it did work, however here what I did:

My personnal info was hashed through keccak as well as various random bits of the program such that if they had been altered it would have been impossible to return a correct hash, that was funny to program however it was probably easy to bypass, this hash was sent to the algo and compared to an identical sequence xored into the init sequence of whirlpool

And then mining would be totally unprofitable. 2% mining fee, 2% pool fee, 2% trading fee, 2% BTC fee. = sell all my cards and don't mine anymore...can't afford to give hash away and it costs me to do so.    Well you get the point.

... and again in case of fee expect rather a minimum of 5%
say new shit 15~20% (or ultra fast optimization min 2x)
      decreasing down to 5% after a while and a after a longer while 1%

As usual you have no idea about anything besides the algos you 'optimize' and have no idea what sort of volume goes through the crypto networks. 15BTC per copy is $7500~ per copy. How many do you plan on selling? 2?

Quark alone JUST on Nicehash has 60GH. At 2% that's 1.2GH. That's .48BTC per day, for Quark alone and that's a smaller one. That's $18,144 per month at current BTC prices. This doesn't include ANY pools outside of Nicehash and we all know those don't exist.

At your 15% you'd be getting 3.6 BTC per day. You'd have 108 BTC at the end of the month for just Quark. I don't think you have any idea what you're talking about. This is why miners with 15% mining fees get neutered, because that level of greed no one puts up with.

I don't think paying someone .48 BTC per day is giving someone something 'for free'. I would be paying the 1-2% just like everyone else.

CCMiner already does pretty much every algo, almost everyone with a Nvidia card is using it. That is A LOT of hashrate and 1-2% doesn't sound like a lot, but it definitely adds up and you definitely could make a company built on this sort of thing. This could also be expanded to AMD cards, essentially every last bit of hashrate for altcoins would be going through this miner. That is a metric FUCKTON of money at 1-2%.

All of this could be done with a handful of programmers, probably 5-10 and overhead. There are already that many big names in the community. 6 working algos, 2 working features, 2 working security. For a small company that is a lot of income.

You guys aren't thinking about the shear scale of cryptos and what such a project encompasses. This is no different then starting a company to make ASICs, only the product already exists, there are no startup costs, and there is NO competition once things get going. Freelance devs wont be able to keep up with a actual company as long as the talent is decent.


DRM isn't a user feature, just to make sure you understand that. That's for your security. Users don't want DRM. It's a negative quality when it comes to selling software.

And then mining would be totally unprofitable. 2% mining fee, 2% pool fee, 2% trading fee, 2% BTC fee. = sell all my cards and don't mine anymore...can't afford to give hash away and it costs me to do so.    Well you get the point.

If 8% makes you unprofitable for top to bottom then you probably should sell your cards as that's a huge investment for really long term risky ROI. You can get 5% on certain CDs.

You don't know how much you're losing due to private miners as well. For AMD cards, this made them completely unprofitable unless you had said private miner. So your loses would be much higher then 2%.

DRM is more or less a time-lock - the more work you put into it, the longer you get before it's useless.

Looking at old blockchains I'm almost sure that Quark version of Smelter got hacked. Well, time to do licensing server.

Encryption, authentication, verification, and updates... I guess developers actually have to try at what they're doing and make a actual program. Maybe even make a company. You know, take shit seriously.

There is and never will be a 100% effective DRM. You just make it not worth someones time to break it. That means fair pricing (1-2% mining fee) for a fair product. In addition to this people DO actually buy software and use legal software, even around here. This is why software companies still exist in real life, even though pirated copies are so easy to come by.

What you are asking is ridiculous (as usual).
If we were to make such program/company considering the work involved, I would not price it below 15btc per copy (which actually isn't bad  )
Would you buy it ? Guess not
And "fair mining" in the 1%-2% yeah right   fee rather 5~15% you are kinda cheap...

Stop asking people to make stuff, you would never buy unless it is free

As usual you have no idea about anything besides the algos you 'optimize' and have no idea what sort of volume goes through the crypto networks. 15BTC per copy is $7500~ per copy. How many do you plan on selling? 2?

7500$ yeah may-be last year  
If your math are as good as your argumentation, I am done with you

and regarding your quark example, I wouldn't get what you say because it is already open-sourced and as you say yourself, most of the algo are already open-sourced...
So a whole company (5~10 dev  ) making a decent %age only on new algo... well good luck with that... hope they know how to hunt so they can eat

Quark alone JUST on Nicehash has 60GH. At 2% that's 1.2GH. That's .48BTC per day, for Quark alone and that's a smaller one. That's $18,144 per month at current BTC prices. This doesn't include ANY pools outside of Nicehash and we all know those don't exist.

15BTC= $7,500
0.48BTC/day * 30= 14.4BTC= $18,144 per month
Wow 

  7500$ yeah may-be last year

Oh man, almost spilled my coffee. 
"The position provides required business equipment, such as company laptop, a spear and a basket."


Anyway, I think if there was a group of very talented coders creating some amazing miners they wouldn't sell it publicly.
Setting up their own farms or selling it to one or two huge farm owners would probably yield more profit long term.
Also less risk of the software leaking or DRM being circumvented.
