Tip:
1040 is magic number for engine OC. Anything over it and you will lower performance from my experience.
Topic: Help getting my 7970 past the 660 Mhash/s barrier - page 2. (Read 6367 times)
I've set the fan speed manually to 100%. I'm gonna try the other setting, thx!
Edit: It worked
Now i get 690 Mhash/s, thx!

Now i get 690 Mhash/s, thx!Code:
cgminer -o stratum+tcp://server:port -u user.1 -p password --shaders 2048 --intensity 9 -v 1
MC: 800
Driver: 9.14

CGMine4: 3.1
Don't set worksize, the default is better. Don't go above intensity 9. Try a different driver. But ultimately, as I said, every card is different. Make sure you're using --auto-fan to ensure it stays cool enough too.
So do you think 660 Mhash/s is really the limit of this one? No chance to get some better results? When mining scrypt based coins, I can easily push it up to 720 Khash/s 
Every card's different in how much overclock it can take. You're simply pushing yours too far.
Once again....the mods like to close and move this topic....however. It's a question about Bitcoin mining hardware.
It's not about Litecoin, it's not about Chinacoin and it's not about BBQ. It's about Bitcoin god damn. Please don't move this topic to the Altcoin forum, mkey?
My Card: Gigabyte 7970 OC (GV-R797OC-3GD)
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.
