Any suggestions for my 290x Neoscrypt settings? Not sure what I am doing wrong to get such crap results. Also how are my 7970/7950 speeds? Running sgminer 5.1.0-dev. Maybe I am using a crap bin or neoscrypt.cl?

290x = 291kh/s (1100mhz core / 1450mhz memory)
--thread-concurrency 8192 -I 13 -g 2 --worksize 96

7970 = 322kh/s (1100mhz core / 1600mhz memory)
7950 = 272kh/s (1000mhz core / 1500mhz memory)
--thread-concurrency 8192 --xintensity 3 -g 2 --worksize 64

I seem to get great results if using xI of 3 or 2 without using TC and a worksize of 64, but I get constant HW errors. As soon as I add TC then no more HW errors, but speeds drop hard.
