well thanks, i see what your saying but i think i might have to just try out 32/64 for longer periods and see..
i know earnings can vary though.. and i've worked on tweaking miners lots about close to a year.
and i have had success doing it... 75% of all miners i run i did a lot tweaking and modding + long term testing.
so i am not stranger to the miners

what i don't know is if the pool is based on shares alone..
i read what it says about it but i still found it confusing which is why i asked.
bottom line is if a lower diff gets more more shares submitted then i *may be making more, regardless of what is good for networking lol
so does the pool work that way ? The web pages explanation was kind of vague on that lol
i am using a bunch of workers such as a cudaminer mod i have worked on since last year running an overclocked Geforce 550Ti
so my Radeon is the fastest worker and funny i have a stock speed Haswell 4770k cpu that is like twice as fast as my nvidia card with only 6 threads lol
anyway i think i will do some longer-term testing and see if makes little difference earnings wise and
i will of-course choose the higher difficulty for the Radeon if it makes no difference.
The other workers i have are pretty slow compared to my one 7950 so.. i'll stay on 32 for them i think.
