I think I found the problem. One of the RAM sticks wasn't in all the way!
Doh!
Thanks all!
Topic: Sapphire 7950 can't go above intensity 13 without HW errors??? [SOLVED] (Read 694 times)

I have a rig with 3 Sapphire 7950s - brand new.
Running cgminer 2.11.4
MSI Afterburner Beta
Current settings - best I've been able to run stable.
setx gpu_max_alloc_percent_100
setx gpu_use_sync_objects 1
cgminer.exe --scrypt i-13 -g 2 -w 256 --thread-concurrency 8192
(followed by correct pool settings)
When I increase the intensity beyond 13 it gives me hardware errors and inaccurate hashing power.
When I increase the thread concurrency, cgminer will start but the GPUs will be disabled and it says GPU 0 Faulure, disabling! Thread 1 being disabled
Error -5: Enqueueing kernel onto command queue. (c1EnqueueNDRangeKernel)
It gives the same error message for GPU 1 as well.
Please help, with the current settings I'm not getting more than 300 khash/s per card.
Thank you!
Edit: Didn't reallize this was Bitcoin forum - maybe Scrypt forum was better, sorry!
