Intensities above 9 are a mistake.
But why hashrate is different on similar cards with similar oc?

Intensities above 9 are a mistake.
Hi,
I'm using BAMT 0.5c(catalyst 11.6) with 3x5850 installed. Hashrate with overclocked to 930 MHz was ~390MH/s and mining was very stable on default phoenix miner.
But I bought 3x7950. So, it was needed to update ADL and CGminer to newer versions. I updated Catalyst to 12.8, ADL to 4.0 and CGMiner to newest 2.11.2. and configure mining on CGminer.
After some magic actions mining on cg was started, but average hashrate with same overclock is ~340MH/s on poclbm and ~360 on diablo (I don't see 5s hashrate because it's some fantastic from 200 to 500). Previous kernel was phatk2, but I think this is not important.
And another strange thing: hashrate on first card is bigger than others. With same overclock it's different for ~30mh/s
I don't want to loose my 50 mh/s on each card, maybe it's bad drivers?
Now second card is 7950, others are 5850,
Here is my cgminer.conf
