What could be wrong? I'm mining it with CPU and it's all right..
Maybe too much work at once for the gpu.
You could try to change some of these parameters,
I would start to try -w 256
-s form 100,000 to 100,000,000 default 15,000,000
-w from 32 to 32000 default 2048
-a from 1,000,000 to 100,000,000 default 30,000,000
-z from 2 to 30 default 10
setting -w < default causes miner crash, setting it > default causes several
pps: -2147483648 / -2147483648 10g/h -2147483648 / -2147483648 15g/h -2147483648 / -2147483648
at the beginning and zeroes later.
I've tried some combinations of -s, -a, -z on the max, min or halfway values, but changing them changes nothing.
Setting -w at very high values (like 50,000) causes things like this:

and zeroes later.
What should be the guide in further testing?
