Hello. 15 WDC reward for the one who helps me to pass the 650-700 kh/s .
I have 2 Gigabyte R9 280X, GV-R928XOC-3GD and I cannot pass the 550kh/s ~ with both of them.
I have undervolted to 1.050 and it is still the same.
The problem is the same with or without risers.
I tried different settings but it doesn’t change.
Please notice that on the same hardware, I have 2 Radeon Sapphire 7950 who run at 600 kh/s +.
The cards run at 50-55°C ~ and 500-550 kh/s with :
–worksize 256 –thread-concurrency 8192 –vectors 1 -I 13 -g 2 –lookup-gap 2 –gpu-fan 70 –gpu-engine 1035
I did set GPU MAX ALLOC to 100.
