Title: Sapphire 7950 can't go above intensity 13 without HW errors??? [SOLVED] Post by: Sancho on February 11, 2014, 09:00:30 PM 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! Title: Re: Sapphire 7950 can't go above intensity 13 without HW errors??? Please help!

Doh! Thanks all! |
