Help needed with cgminer

[ifowler46]

I been spending hours trying to get a HD4850 mining scrypt coins. Thought I would see if anybody could help me. This is the command i have try to start cgminer with.

Code:

--scrypt -T -o stratum+tcp://xxxxx.xxx -u xxxxxx -pxxxxxx --thread-concurrency 400 -I 10 -g 2 -w 128

It will just sit at setting pool difficulty. I change thread-concurrency from 400-3000, -g 1 and -g 2, I have also changed the worksize to 256. Nothing seems to work. I'm using the 13-9-legacy_vista_win7_64_dd_ccc_whql driver with the AMD-APP-SDK-v2.7-Windows-64. If i don't install the sdk opencl is not installed on the system. I've done multiple uninstalls of drivers and re-installs. Gpu-z and furmark both see opencl after the SDK. The bitminter program will mine as long as opencl is install but cgminer sits there stalled.

I have tried starting cgminer with

cgminer.exe --scrypt

and enter pool info. After hitting enter after the password it will just sit there doing nothing. I try using text only (-T)same thing.

EDIT: Turns out re-installing windows 7 and installing the driver fixed the issues that I was having. I used the latest driver for the card 13-9-legacy_vista_win7_64_dd_ccc_whql.exe

Have you even successfully got it to run?

If not, then remove all of the settings and try again, then tweak the settings to find it's sweet spot.

Also, there is no need to censor the pool info.  The only thing people could do with that information is mine coins for you, and that is only beneficial to you.  Besides, what if you have something really silly like an incorrect pool address?  We couldn't help you with that if you x it all out...

EDIT:  Just saw that you have tried running it bare... maybe give sgminer a try.

Are you using version 3.7.2?

[ifowler46]

Not on scrypt the bitminter program works fine.  I download a fresh copy of cgminer and ran cgminer.exe --scrypt and entered the pool info. Is that starting with no settings? If i run cgminer.exe it seems to use the sha256 kernal and reports hash rate in MH/s.

It will stay like this with no gpu load

Strange.  Definitely looks like it is connecting to the pool since it is displaying the difficulty.

[ifowler46]

Yeah that's what I thought. This card is really stumping me maybe because its a 4000 series?

Are you using version 3.7.2?

I have tried these with the same results
2.11.4
2.11.2
3.2.0
3.7.2

I also tried different versions of bfgminer same thing happens just sits hung up using 100% of a cpu core.

Here's an update of my problem I'm having with cgminer. I thought for the heck of it I would see if cgminer would compile other kernels and it does, every one except scrypt. I used GPU caps viewer to see if opencl was working it runs all the demos for opencl. The luxmark-win64-v2.0 benchmark also runs fine. So at this point I assume opencl is installed and working correctly? Anybody have any thoughts?


This is the config I'm using
