For Nvidia ccMiner 8.15(KlausT-mod)
For AMD Gateless gate
The fastest.
The Gateless Gate outputs half performance of NSGminer on Linux with either 17.40 or 16.40 drivers. Haven't tested it any further.
CUDA performance will be improved soon to match and maybe exceed.
I have tried both NSGminer and Gateless Gate in windows..
Gateless Gate
RX480 750KH
RX570 750KH
NSGminer
RX480 500KH
RX570 500KH
So it's not the fastest.
I have RX570 and i get 600 KH/s for NeoScrypt using NSGminer
What wrong with your card?
Do you have flashed mod bios and installed Amd blockchain edition driver?
