BTW: Go Sapphire all the way. Solid as a rock at 0.962v and getting 730kh/sec out of it.

Model and cgminer settings please.

Sku is 11197-03

intensity 20
thread concurrency 40960
shaders 2048
gpu-engine 1100
gpu-memclock 1500
powertune 0

Ah, so this is overclocked. Are you also using the --verbose flag to see if you're getting any HW errors on that intensity?

I am getting 730KH on my 7970 using these:

--thread-concurrency 8192 --gpu-engine 1050 --gpu-memclock 1470 --gpu-powertune 10 -I 13 -g 2 -w 256 --lookup-gap 2 --verbose

These shitty cards are amazing... With any other settings I get from my 7970 more than 540 KH/s (but no where near 700 KH/s), with your exact settings I get 413 KH/s. Fucking unbelievable... Angry

Truly fucking unbelievable. I wish I could be of more help but mine are quite common and conservative settings (sans the overclock, without which I was getting ~620KH) so I maybe your card is faulty?

I don't know, this is making me crazy, I'm doing all the combinations of GPU from 900 to 1100 MHz vs memory from 1000 to 1600, in 10 MHz steps -> 1200 combinations. And this is only a 2-parameters experiment. Roll Eyes

Have You tried other versions of Catalyst drivers? And some older CGminer can help as well - I am still using 2.11 on my two rigs, because everything above 3.X I´ve tried sucks..
