What exactly are you seeing here? I've only got an Amazon EC2 instance to test on, and I don't get an issue. You're Ctrl-C-ing?
Yea im doing ctrl-c to exit out of the app in a dos prompt on win 7 |

What hashrate where you getting without cuda?
guiminer poclbm gives me ~137.5 How does your 480 beat a 680?  you overclocking at all? Im getting around 122~ give or take with cgminer |

Has anyone done tests between windows and ubuntu.. as to whats more stable or better hash rates.. obviously windows is easier to set up.
I'm also seeing people using the latest cat drivers 13.1 reporting good results.
So also whats the deal with memory..
some people say to keep mem 150 lower than gpu clock.. see memdiff setting in cgminer..
My by default has a gpu clock at 1000 and memory at 1450.. just sorta kinda trying to figure out a good combo.. of course this requires some serious babysitting to see when it goes down.

Can you run the miner same minits that we can see the hashrate. My driver under windows also crash, thats windows like shutdown^^ Here is what im seeing..

Mh, the selection of your device crash. I add later some more output which device is selected. In most cases there is a problem with the driver. I'm seeing the same results, yesterdays build I was able to run, today with the changes.. aka required cudart and then when having it provides the same output.. GTX 680 |

why are you oc'ing your memory ? you're doing litecoins ?
From what I understand its good to keep the memory down under 150 below the gpu... but im still learning a bit.. |

Do you have 32-bit CUDA SDK 5.0 installed?
I get the same error, no I never installed cuda since I wasnt compiling this, I have the latest nvidia drivers tho since this is my uber gaming rig..  any chance to include the dll? EDIT: .. installed 32bit version of cuda 5 from nvidias site.. now when I run the miner I the program crashs.. its not missing the dll .. but Client will start 1 miner threads Work will be refreshed every 4000 ms 1 GPU GUDA device(s) found <src\cuda\bitcoinminercuda.cpp>:54[CUDA] Error: invalid device ordinal |

13.1 which comes with 2.8
Stock 1100MHz, with 950 memory, 1.256V, Powertune set to default, and 80% fan, 66C @ 661MH/s.
nice on the temp.. what card are you using and do you recommend it.. At that voltage you should be able to push to 1040 maybe.. not sure what settings you tried. |
|
|

I can confirm im getting the same thing.. when running rpc a window pops up and says the program cant start because cuda32_50_35.dll is missing from your computer.. seems something went whacko |

Just taking a poll as to see what people are running..
Currently I have C 12.8, which I believe comes with sdk 2.8
I'm running cgminer on a sapphire 7970 oc'ed
settings:
gpu = 1183
mem = 1040
v = 1243
boost 20
temp is around 72, with fan speed of about 83
pulling in 702-698~

I have stock 7970, 2 per rig and on each rig one runs around 600mhash but the second is always around 370 to 420mhash.
Played with memory clock, gpu, v, I... But no changes - any idea for optimal settings?
Currently using settings from guiminer-scrypt as is and modified gpu to 1130 and memory to 1050 as found on wiki.
Any help appreciated, would love to get close to 2600 / 2700 Mhash rather than the average 2000 I am getting now.
Are you doing litecoins, have you tried cgminer by itself? What card do you have.. |

OK, switched back to faster kernel.
GPU Overview update:
C1070 - old GPU - 30 Streaming Multiprocessors (SM) - ~46MHash/s (slows down with the last patched kernel)
C2050 - old Fermi - 14 SM - ~ 107MHash/s
K20c - new Kepler - 13 SM - ~ 325M - 350 Hash/s
what exactly is K20c ? just so we know here.. and what gpu are you using right now, I cant wait to see 300+ on my 680 ... |

Im pulling in around average of 700~ with my sapphire 7970 OC...
gpu 1182
mem = 1043
vddc - 1231
boost 20
cgminer

I have a Sapphire Radeon HD 7970 OC with unlocked voltage..
Using Sapphire Trixx to adjust settings im running right now around 700.. trying to push it a bit more but slowly..
settings for the card are.. 2nd bios setting
gpu 1175
memory 1040
vddc (voltage) 1231
boost 20
I think i can push the gpu and voltage a bit more tho..

Might as well jump in ....First..no linuix ...just a point click, old guy in Win 7.
I have 2 - 580 GTX. Using CGminer I get 160-200 Mhash PER card . (depends on overclock and using Comp or not)
Trying this..@ first i had the "Unable to load CUDA module: 209" error. I grabbed the other .plx file bitcoinminercuda.20.ptx. Renamed it and...
Now i am getting "curl return Value = 7"
Kinda getting lost here...lol These are some of the Command lines tried....
rpcminer-mod-cuda.exe -aggression=8 -gpugrid=64 -gputhreads=384 -o - url=http://stratum.bitcoin.cz:3333 -user=####### -password=#####
rpcminer-mod-cuda.exe -aggression=8 -gpugrid=256 -gputhreads=512 - url=http://stratum.bitcoin.cz:3333 -user=###### -password=#####
rpcminer-mod-cuda.exe -url=http://stratum.bitcoin.cz:3333 -user=##### -password=####
rpcminer-mod-cuda.exe -url=http://localhost:8332 -user=##### -password=#### <<(set according to Bitcoin.conf)
"curl return Value = 7"
Thanks for all the hard work you guys do, would really like to get these cards working better (they are embarrassed to announce their terrible Hash rates to all the other cards on my network. Especially the 7970 getting 720 Mhash...lol).
dont use the stratum url us this instead.. btcguild.com:8332 |
|
|

this is still very exprimental. at linux os i get 350-370 MH/s while in windows only max 120MH/s.
i will try to make an workaround to it
wow thats a huge jump on linux.. be great to see that for us windows users! What card are you using? |

thanks for this, I just got this card and working on getting it past 700 still, have you also tried the sapphire trixx? This allows for adjustments as well and core voltage out of the box, for some reason even though I adjusted the msi afterbuner config I was still unable to adjust the voltage.
this is my current command line
-v 2 -w 256 -k diakgcn -I 9 --temp-target 75 --auto-fan
core at 1155 , memory at 1040.. haven't played with volt adjustments yet.
Have you tweaked your settings lately? Also what driver or sdk are you running..

I have a GTX 680.. just tried to run it but it spit this out..
Client will start 1 miner threads
Work will be refreshed every 4000 ms
1 CUDA GPU devices found
Setting CUDA device to first device found
Loading module bitcoinminercuda.ptx
Unable to load CUDA module: 209
then it exits..
