Hey some 290 settings, this will give 62khash at 977core :
--scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -I 16 -g 1 -w 64 --thread-concurrency 85000 --lookup-gap 3
This is better than going 90000 TC with lookup-gap 4. Itensity of 17 and higher slows the system by a huge amount(at least for me). There may be room for improvement but I have already achieved 280x/290 ratio of 0.81. I have 8gb of ram + 16gb of pagefile(set as a constant).
Cause people keep asking for 290 settings.
Also I have played a lot with 280x both lg=3 and lg=4 and these seem to yield best results(they are not mine): I agree its time to go yacminer, with default cgminer there are not enough options to tune intensity.
--scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -I 12 -g 2 -w 256 --thread-concurrency 32768 --lookup-gap 4
