Ok came to another deduction is that the problem is with the scrypt and groestl algos. Their blocks overwrite the others. SHA256 is fine.
We need your opinions to strip out Scrypt and Groestl.
Please give your views so we can do this fast and make SFR a 3 algo coin - sha,X11,blake.
block 116297 here.
But now I'm solomining with just 2 gpus.
groestl was fine for me and a also lot of miners with old AMD gpus. But if the solution is to keep X11 and blake and stop scrypt and groestl i'm in.
I don't like scrypt these days. too much heat for summer and too many asics coming soon.
