I have the same cards on my 4 card rig. 11196-19-20g I found are sensitive cards. My stable settings ---> 614-619 khash, 950w from the wall (voltage adjusted to 1093 using trixx), no hardware errors, 70-75C are:

-s 2 --expiry 1 --queue 0 --lookup-gap 2 --gpu-engine 1025 --gpu-memclock 1500 -I 19,20,20,20 -w 256 -g 1 --gpu-powertune 20 --thread-concurrency 20400

• 20 intensity on first card causes lower hashrate on my rig, no idea why
• fan settings is your preference
