5830 card no longer hashing at the previous rate (CGminer software)...

[JayBee66]

I am having a problem right now.

My Litecoin pool went down so I decided to reconfigure for another pool. I re-wrote the config batch file to point to the new URL but the card would not work, a 5830.

If I tried the original I=20 intensity the screen would momentarily blackout and the driver would fail then recover. CGminer would then report the GPU as sick and shutdown.

Since then the old pool has come back online and, using the original config batch file, I can still no longer get any meaningful hashes at I=16, about 7kH/s. Any attempt at I=20 results in the same driver failure.

I have used 12.8 and 13.1 AMD drivers. Cleaned out all and restarted. Using the latest cgminer.

Has anyone had this problem too or might know what the problem is?

Thanks!

Nevermind.

Switched to Guiminer-scrypt and all is well. CGMiner corrupted on my system and reinstall doesn't help.
