Hi all -
Got my first HD7970 GPU today and after plugging it in and running litecoin BAMT I am only getting on average 100Kh/s.
I have tried just about every configuration I can find and still it always averages at around 100Kh/s.
Using an old Dell (Optiplex GX280) with P4 3.4Ghz cpu, 1Gb ram, no hdd, no other cards.
Could the stock dell power supply be the problem?
Tried:
--intensity 13 --worksize 256 -g 1 --shaders 2048 --thread-concurrency 8192 --auto-fan --gpu-memclock 1650 --gpu-engine 1110
--intensity 13 -g 2 --thread-concurrency 8192 --lookup-gap 2 --gpu-engine 1044 --gpu-memclock 1500
--shaders 2048 --thread-concurrency 8192 -I 14 -g 2 -w 256
--worksize 256 -v 1 -I 13 -g 2 --thread-concurrency 8192 --lookup-gap 2 --shaders 2048 --temp-target 75 --temp-overheat 80 --temp-cutoff 85 --auto-fan --gpu-fan 0-80
All produce the same result around 100Kh/s
Any ideas?

Two thoughts. 1) You only have 1GB of RAM and that matters with scrypt. 2) Your AMD OpenCL/drivers are probably not ideal.

Thanks - will get some more RAM from a friend tonight and try it out.

Does this driver need to be replaced / updated?

Try flashing the card with non OC bios. Can be found on techpowerup.

Wait, Are you using a 230Watt PSU for a card that uses more then 300watt on full load..? If so, upgrading your RAM will NOT solve the problem. Unless you get a PSU that provides enough power.
Edit: I cannot into correct sentences.

Try this - go to your device manager winkey+pause, then select your onboard graphics and disable (even if you are certain that your graphics card is the default)
Reboot your PC, and hopefully you should be full speed.
