Hi all!

I made a fork of SPH-Sgminer for Groestl algorithm. See here: https://bitcointalk.org/index.php?topic=652849

If you have AMD GPU, please try it. I'm getting 16.2 MH/s on R9 290 and 7.56 MH/s on R9 270X.

In a few days I'll post 17.0 MH/s R9 290 kernel (I'll post update in this forum).

I'm planning to work on improving this miner in the future.

You don't need to specify difficulty multiplier anymore.

If you have any problems with this miner - please post directly into that forum.

PS: If you are on NVidia, you might want to check out ccMiner 1.1 (it just got got substantional speed increase for Groestl mining)

Thanks

Hi srcxxx
I get 11.57 Mh/s (+ 1Mh/s) on R9 280x at Core 1100Mhz MEM 750MHz win 8.1 Catalyst 14.6

Work fine for me - 15.07 Mh/s on 280x : Core 1130 mem 1000 , win 8.1 , 12.13 driver

Can you please share full settings and card manufacter?
