[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[cbuchner1]

My card used more than two years, I just used it gaming and sometimes do the BOINC computing or mine some btc. Is that possible that two days I just triggered the death of some chips on GPU?

highly unlikely, but certainly possible.

I am running a 660Ti 24/7 at 90 deg celsius (!!!) and it is still alive.

Guys, I wonder if anyone is using GTX 780s to mine litecoins? I already do this using my 7990 system with no issues but when I try to set up cudaminer in order to utilise the 2 x 780s in my other system, I am getting no hashing.

I installed cuda 5.5 (64bit) and set up the .bat file in the cudaminer directory but when I run it, no autotuning takes place and hashing never really starts.  Cudaminer launches and attempts to hash and my system becomes hiddeously slow, taking 1 minute to move the mouse pointer. The script appears correct and is taken from my pool's configurator (litecoinpool.org).

Are there any other dependencies required in order to mine with Nvidia cards which I am missing?  I saw the OP has put some other dependencies for windows but I am not sure what to do with them?  They don't seem to be as straight forward as download and install?

You need drive about like 3xx or something, can't remember the exact number. make sure the drivers are up to date

My GPU drivers are the latest ones.  311..something.  Is there anything else I need to install apart from Nvidia drivers and Cuda 5.5?

331.82 is the latest.

On Windows you don't need to install CUDA seperately. CUDA is included with the driver.

Thanks.  I'll uninstall everything and give it another go with a driver reinstall.  Will the autotune detect both cards or will I need to write the script to reflect the setup?

I'm not sure what the defaults are.
With -d you can specify what devices you want to mine on, for example
-d 0,1 -i 1,0 -l auto,auto -C 0,2 -H 1

http://forums.guru3d.com/showthread.php?t=379506 Display driver uninstaller, good for clearing everything out before a new install. Newest driver as of right now is 331.93, didn't give me anything over 82 though, it does have newer sli profiles for games though which you would benefit from I guess.
If you want to use different setups for the cards you can do that, check the readme, it explains how to with an example setup. Otherwise it'll just use the same settings for both if you don't specify anything else far as I understand it.

Thanks guys.  I installed the latest drivers and am up and running and it shows a hashrate of around 300kh/s.  Currently I have SLI disabled.  Is it best to mine with it enabled?  Also as it is (disabled) it seems GPU 1 only achieves 70% utilisation and GPU 0 achieves 99%.  Cudaminer window only shows GPU 0 accepting blocks and nothing for GPU1. 

My script in the bat file is as follows:

Code:

cudaminer --url=stratum+tcp://litecoinpool.org:3333  -i 0 -l auto --userpass=u:p

Any tips on how to utilise both my cards at the same time?  Was expecting around 600 kh/s.

[alex_123_fra]

Ok spoke a little too soon.  Hash rate on 2 780s is now 620 khash/s.  Utilisation is 70% for one, 78% for the other.  Is this about the best I can hope for or can the cards be maxed to give more?

[CubeOne]

I get a error "json failed", How do I fix that? Thanks.

[atomton]

Just for the records:

Compiled cudaminer on OS X 10.9 with the CUDA 5.5 Toolkit, gcc 4.9 and the Compute 1.1 spinlock kernel: 39 KH/s on a GT 650M. Now, I compiled it with the CUDA 5.0 Toolkit, gcc 4.6.4 and the Compute 3.0 spinlock kernel: 59 KH/s.

Thank you. After one day whole day running cudaminer, I stopped it and tried one game. At the beginning it seems working fine again, but after a while it went back to unstable. That was so weird.

Ok spoke a little too soon.  Hash rate on 2 780s is now 620 khash/s.  Utilisation is 70% for one, 78% for the other.  Is this about the best I can hope for or can the cards be maxed to give more?

Based on my understanding of the readme, try removing one card and then find the best combination for the other card, then put the other one in and do the same thing. Then use the appropriate launch config for each card. Try it with -i 0 -H 1 -C 0/1/2 -D. Do a few runs and see which one gives you the highest hash rate, note down the launch config (letter)number x number, then use that with the -l operator.

Edit: guess you could specify an device with the -d operator and not have to remove or disable anything

For reference, I'm getting 99% usage and 320kH/s on my 580, albeit highly overclocked but still, you should be getting quite a lot more imo.

Is there any way I can adjust the reconnect time? I mine on hashcows and would like cudaminer to reconnect faster when the mined coin changes.

[Ragala]

Hey I was wondering if anyone is using a GTX 650 to mine and could help me. I looked at the spreadsheet and it said my card is supposed to have around 180 khash/s. I only get 40-50. Anyone know what I can do to optimize cudaminer?

Thanks

I face the same issue on Windows Server 2012 R2 machine with the 780 Ti. I cannot get anywhere near 100% utilization. trying Linux now for comparison

Hi,
it looks like new version isent working well with proxy.

I got proxy on my site,
when i try to connect via cudaminer like

cudaminer --url=stratum+tcp://litecoinpool.org:3333 --userpass=my_nick.1:1 --proxy http://my_proxy:port

WireShark is showing me still all my connections to litecoinpool is going directly by firewall. Not via Proxy.
Im making something wrong or it`s rly some kind a bug?

[cbuchner1]

stratum is a TCP base stream protocol where the connection stays open all the time.

There are no proxies for stratum. You could develop one.

I posted a 2013-12-07 version. Most notable difference is that the Fermi kernel now targets the Compute 2.0 architecture explicitly. Expect maybe a very small boost in hash rates. For me it went up from 228->235 with the cudaminer x64 version for my Compute 2.0 card.

Next work item on my TODO list are:

-make cudaminer suitable for >1 MHash/s operations, even with weak single or dual core CPUs
 by doing the required SHA256 hashing (for scrypt) also on the GPU

-finish and operate my 1.5 MHash/s build (3x GTX 780Ti in one mainboard)
