I think I found the problem. One of the RAM sticks wasn't in all the way!
Doh!
Thanks all!

I tried all of that and it reports the same error I quoted in the original post.
The GPU fails and it talks about enqueueing kernels.
No idea what to do.

4GB.
I have two other rigs with 7950s and no issues like this - only the brand is different.

I have a rig with 3 Sapphire 7950s - brand new.
Specifically - SAPPHIRE 100352-3L Radeon HD 7950 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
4GB RAM
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!
