Help Sapphire HD 7950 Settings

[Reckman]

I cant for the life of me get two of these above 500 each, everywhere I see people getting 620+ easily

Do I need to change the firmware?

GPULoad on one card is low o.O TC too high?

Code:

-g 1 -w 256 --auto-fan --gpu-engine 1150 --gpu-memclock 1450 --gpu-powertune 20 -I 20 --thread-concurrency 22400

Google this:  "Poor hash rate on Radeon 7900 / 280X"

Search that thread, try any appropriate bios, or ask in the thread for your own to be modded.

Thanks, i'll try that out

donation address if it works out?

[poohbah]

Not necessary. Donate to The Stilt if it works out. He's done very interesting things.

try this:
 1150/1450 core/memory clock speed
 Thread Concurrency - 24000
 Workload - 256
 gpu-threads - 1
 lookup gap - 2
 Intensity - 19
 gpu-powertune - 20

or

gpu-threads - 2 , and low TC - about 8192

worked like a charm, no amount of configuring could fix that
