Is this a problem, or not?
I have 2 open crate mining rigs identical with 4 Sapphire Radeon HD7970s the OC with boost. Both rigs run cgminer with Win7-64. Both hash great at about 730 Kh/s at 79 degrees. No complaints there. But each rig on GPU 3's card gets about 1 HW error a day. Is this normal? Should I try to change anything?
here is bat:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://gigahash.wemineltc.com:3334 -u pool user name.1 -p password --thread-concurrency 8192
--intensity 13 --queue 0 --worksize 256 --auto-fan --temp-target 80 --temp-overheat 90 --temp-cutoff 95 --gpu-engine 1050 --gpu-memclock 1500 --gpu-vddc 1.2 --no-submit-stale -g 2 --lookup-gap 2
p.s. I have undervolted before but I am leaving at 1.2v until HW errors are resolved.
