I'm building mine out of crates right now with filtering, I'll post some pictures and price estimates when I'm done

Post what your card is and your settings, sounds like thread concurrency is too low
Edit: isn't port 3334 litecoin on coinotron?

This has been addressed many times
If you directly port the scrypt cpu code to gpu it's faster on the cpu using the l2 cache. So, Artforz thought it was faster on cpu than gpu. With an optimized algorithm that reads sequentially and has on the fly lookup table reconstruction it's not true. Artforz was pretty embarrassed by this lapse in technical prowess and left the scene, which has been rife with conspiracy theory since.
There is no way to easily make a cpu only coin either, see my "memcoin" thread where I learned why it was a bad idea with scrypt

OK so you are saying with latest version of GUI miner scrypt, it will just work with a 7950?
Also, how do I tell which version I am running...?
Yes. The only version that's up right now is 0.03. Usually the version is in the about screen, but its possible I didn't update it going to .03 (wrote most of the fixes while I was supposed to be sleeping after 12 hours of work). Anyway, if cgminer works with high thrrad concurrencies its the latest version, if it crashes it isn't. |

Something is weird with the 2.11.3 kernel. I can't use it very well with my 7950s, I get the same hash rates as with reaper but with about 5% invalids. Not sure why this is. Try rolling back to one of the older scrypt######.cl files and seeing if that fixes it.

so here i'm still with same probelm.  i waited for more then 3 minutes.. (about a hour) and still saying [2013-03-20 16:18:18] Error -1: Getting Device IDs (num) you mentioned also this coed: 2013-03-20 16:18:21: Listener for "cgminer": .. this one i cant see there just that one above I also wanted to install that ADL library you send me link, but after i uzip it icant find any executable file.. there is just html, wuth some documentations Hm. When you run guiminer-scrypt, open the console, then go back to your cgminer tab and hit start. In the console you should see a command like: 2013-03-19 23:17:10: Running command: C:\guiminer\cgminer\cgminer.exe --scrypt -u user -p password -o stratum+tcp://ltcmine.ru:3333 --gpu-platform 1 -d 0 -w 256 -v 1 -I 14 -g 1 -l 1 -T --thread-concurrency 16000 Go into the windows command console (start --> type in cmd --> run cmd by clicking on it) and then copy and paste all the code after "C:\" (to paste into terminal, right click and select paste). Then at the end of the command, type "--debug" after "--thread-concurrency #####". Hit enter and let me know what you get for the output, it sounds like a problem with cgminer. |

version 0.03 sets the environmental variables automatically, so no need to open the console.

I'm never mad, just tired. Litecoin has gone from being a hobby to a major source of income for me now, as my graduate stipend is frankly awful as the gov't cuts more money from science and edlngineering, and my wife also has a disability that keeps her from working, so I'm starting to worry more about the health of the chain and of course I'd be worried if a scammy company like BFL would come out trying to sell Litecoin hardware.
The professionalism is my concern, not whether or not there are FPGAs or whatever. I can always sell my GPU rigs and buy FPGAs later.

I turn 14 in September.
Okay. I respect the fact that you spend a lot of time on Litecoin, but it'd be beneficial if you turned down the anti-gay/pot rhetoric and trolling a bit. Of course, this is coming from one if the former capital trolls here, but I've been trying to get a little more serious lately. |

ASIC is the eventual way to go, FPGA paves the way by making an implementation consisting only of discrete logic units.
I've been a little dubious from the start (especially that they've chosen a 13 year old as one of the alpha testers), but laSeek seems dedicated and I'm interested to see what he comes up with.
Not sure who you mean is alpha testing it, no one has the unit but the vhdl dev for the time being. And as noted before laSeek is only advising he is not the developer. Oh, he's the one I'd been getting info on about it before. Who is the actual dev? As far as alpha testing I'm talking about Simram, since he's suggesting in this thread one if the first units is going to him. |

The slow speeds are on real chips. The simulations are what runs fast.
They're working on a lot of optimizations for the N=1024, p=1, r=1 scenario that is the current implementation. I think it's more of a technical challenge for laSeek as an FPGA engineer than anything else. It'll be interesting to see if he gets it off the ground.

Where do I get OpenCL.dll, How do I open THAT and then where does it go?
Can't somebody write a frickin download that will do that automatically?
Why isn't it in the miner to begin with?
Is this 1993 or what?
OpenCL.dll is vendor specific, you need to get it from the AMD drivers and APP SDK For anyone interested, I forked guiminer to make one for litecoin. Link is here: https://bitcointalk.org/index.php?topic=150331.0 |

Navigate to the build folder with cd then |

My cards measure 160-180w at the wall, but only about 110w through those calculations (mining litecoin). Best to measure at the wall.

Hi, If you see, 2013-03-20 16:18:21: Listener for "cgminer": [2013-03-20 16:18:18] Error -1: Getting Device IDs (num) this is normal. I'm not 100% sure what causes it yet, but it doesn't seem to affect mining at all. Anyway, after this the kernel usually builds for cgminer, so wait 2-3 minutes and see if it begins mining after that. If not, something else is wrong unrelated to the above error. The ADL Library is here too: http://developer.amd.com/tools/graphics-development/display-library-adl-sdk/Usually it comes with your driver, but you can try installing it as well |
