1  Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN] cudaMiner - a new litecoin mining application [Windows/Linux] on: December 06, 2013, 09:31:06 PM
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?

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?

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

Screenshot of what it looks like (click twice to enlarge):


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

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

Baffles me how any vendor can accept a coin that is likely to fluctuate so wildly in value.  Big risk.

You may use BitPay, it convert your Bitcoin order to your local currency instantly, so the Bitcoin price you have to pay fluctuate instead

Oh I see.  So then the risk is with the buyer in terms of the price they pay for the item (depending on how much a bitcoin is worth at that time).

I'd be interested in this too.  We have already heard how BTC-e was dodgy.  I am not sure what reliable place there is to transfer your coins from your wallet to exchange or withdraw?

What other options are there instead of BTC-E?

I have only just started mining and have only like 5 LTCs but I haven't even tried to withdraw them from there?

I was planning to exchange them for bitcoins and then transfer to Mt.Gox.

Just found out about this rule myself.  I thought my browser was broken.
