Hi folks.
I have just gotten back from a 4 month hiatus. Back when bitcoins selling for under 3-4 bucks. Anyways back in 2011. I was running fine with guiminer with phoenix kernel hashing out 350-400 Mhash/s on 5850s. Using phatk 3% mod on 12.1/2.2 sdk running at 900/300 specs.

Nowadays with the new guiminer and different kernels I cant' even reach the old ratings. Hitting 300-340 million hashes per sec at most. I'm running with poclbm on guiminer with the code, "-v -w128 -f25". Any help is welcomed.

If you have updated your AMD drivers/SDK that is most likely what is causing the lower hashrate.
