Hi,

I'm gonna reopen this topic, because a mod moved the original one to the altcoin forum, where it moves to the 2nd page within one hour. Nobody there is interested in mining hardware. They're just hyping their new coins.

I have a Gigabyte 7970 OC (GV-R797OC-3GD) and I'm trying to mine a SHA-256 coin.

Code:
cgminer -o stratum+tcp://server:port -u user.1 -p password --shaders 2048 --intensity 14 --worksize 256 -v 1

CC: 1100
MC: 800

Driver: 9.14
Catalyst: 13.1
CGMine4: 3.1


That give's me about 660 Mhash/s. Now, if I try to higher the core clock , let's say to 1150, my hashrate goes up to 690...but then, after 1 minute or so, my card crashes and I have to reboot. Any idea how to solve this problem? Thanks.

Looks like you got moved yet again based on the original title of this thread that was in Khash, but you've since changed it...
