Hi there

I've got a mining rig with 8x 280X DirectCU II, but i'm using linux.
Stable setting for me (undervolted to 1.137v):

thread-concurrency 8191
gpu-memclock 1500
gpu-engine 1108
gpu-powertune -20

I'm using the modified scrypt130511.cl from Zuikkis: https://litecointalk.org/index.php?topic=6058.msg96647#msg96647

This is giving me stable 780 k/hash

Cheers

If i use the following setting display drivers are crashing after 10-15min but that time i am getting 760 kh/s

Code:

Can you please let me know how to get best hash rate without crashing display drivers.
