@ badman...
Could you tell me what each of these do, and to which algo's each applies to?
"hamsi-expand-big" : "7",
"hamsi-short" : true,
"blake-compact" : true,
"keccak-unroll" : "8",
"luffa-parallel" : true,
I used all 5 and it helped my X11 a bit, but hurt X13 more than it helped X11.
I haven't tried any other algo's yet.
the hamsi ones are for x13
blake, keccak, and luffa are for all x algo's plus a few more and the settings for them are dependent on the card
i.e old cards need most of them to be set to 0 or false
while some need hamsi-expand-big to be set to 1 or 4
my settings generally work for 290's and 290x's
while my 7750's need everything set to 0 or off
luffa-parallel gives me 100k increase but it was said to cause crashes with some cards
keccak-unroll usually only gives around 50k increase for me
blake-compact gives about 50k as well
with every thing combined my 290's get 5.26mh/s on x11 while my 290x's get 6.1mh/s
you can try different settings on each to find what works best for you
they should build different bin files for each combination
