Hi Guys!

So I have a Powercolor 7970 (Non-ghz edition, but custom powercolor cooler) which seems to work great mining BTC, with speeds of 630 MH/s (when OC'd to 1125 MHz core clock) (using GUIminer).
The problem is that if I try to hash a scrypt cryptocoin (LTC, BTB.. etc.), using GUIminer-scrypt alpha, I am stuck at 320 kh/s!
Obviously something is wrong... I've tried changing many settings... but can't get higher than this speed.
My thread-concurrency is 8192, intensity is 13, gpu threads is 2, worksize is 256, and vectors is 1.

Thanks a lot!
