Hi Guys
Hope someone can help.
cgminer.conf file enclosed.
Getting hashrate 593 for my 5850 which is good I think, but posting no shares accepted.
Any suggestions please?
I'm running cgminer with just the conf file.
With a bat file and no auto settings I can get a regular share acceptance rate, but only half the hashrate.
Thanks!

Hi GodammerWrung69

Have you tried running CGminer without options and deleting the conf file? In my short experience the first time CGminer or BFGMiner is run, the best is doing it with no command line options or conf file. Once the miner is running and spiting shares, press S > W > ENTER to save the autodetected settings. Then you can makje a copy of the conf file and play with it.

Also, it seems to me that you are running Windows but the path to the kernel belongs to Linux. As I said, try the above method and let me know how it works for you.

cheers

Change:

And test it.
I thing it help you.

Hi
Thanks for quick reply!
yes running win7 64bit.
Attempting to mine ltc / or derivatives.
Whatt would be the correct kernel path?
I ran cgminer direct with old conf files disabled and the file it created certainly gave a much better hashrate than my bat file, but again no shares being generated.
Here's the unedited file (which of course is missing the "scrypt" : true, line which I think needs to be inserted?
Thanks!

Hi thanks for reply. once running it sets the intensity to about 5 or 7 usually, so not sure the intensity is the problem.
Something else appears to be preventing it generating shares.
Once I've edited the file by inserting Thread concurrency to recommended settings for card ATI 5850 - 5600) and added a line for scrypt, it still generates no shares :(
I'd love to use the config file with higher hashrate but, but not generating anything for me yet.

Thanks!

Hi,
I don't know about a diablo kernel, but my config is doing fine with

"kernel" : "scrypt",

Hi Rob,
Thanks for reply.
Gah - amended that and now getting following error:-

I've used the concurrent-threads and thread-concurrency commands but neither seems to make any difference?
Hate teething problems :)

Dump that Windows rubbish, and mine on a headless linux box. Got my intensity set at 20, with no problems.

Change the

"lookup-gap" : "0",

to

"lookup-gap" : "1",

so that you don't have to divide by 0 ;-)


edit: recommended value is 1 anyways..

Thanks lol - it FINALLY started mining (once I'd added the "scrypt" : true, line, but hashrate way down to 9k :P
I've reverted to Bat file for now - that works at circa 200Khs - better that than nothing!
Thanks for help :)

Read the scrypt-readme in the cgminer directory - it has a good guide on how to get your gpu running

Yeah done that - thats how I set up the bat file to work successfully - just thought I'd try the conf file as it seemed to give a higher hash rate - I'll stick with circa 200khs for now I guess.
Thanks for help again though!

Not sure about that, but maybe your graphics card just has a slow memory speed and the higher HR was only possible for SHA mining and not for scrypt..
