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 Title: Re: Asus R9 280X DirectCU II Display driver crash Post by: gg234 on March 07, 2014, 05:21:42 PM Thanks for your reply and i am using the following settings and getting 750k/hash constantly without displaydriver crash
