Been using an old dual 5970 rig for a long time, it's all worn out and can hardly run stock speeds anymore. I haven't used it much for X11 but have been trying it for a bit now and am getting these weird stats:
Does anybody know why 1 core is 50% faster than the others?
bat file:
sgminer.exe -k x11mod -o pool -u user -p x -g 1 -I 18 --lookup-gap 2 --thread-concurrency 8000 -w 256 --auto-fan --gpu-fan 70-100 --temp-cutoff 100 --temp-overheat 95 --temp-target 78 --gpu-memclock 500-700 --gpu-engine 600-700 --expiry 1 --scan-time 1 --queue 0 --no-submit-stale
Tried a few SGminer versions, this screenshot is from the 14.6 fix one, all sgminers I've tried do this same thing, gpu 2 is always 50% faster than the others.
Current driver 13.12 on Win7 64
This does not happen when mining scrypt or Blake or Nist5 with this rig.
Also tried running just 1 core at a time, same thing.
