sooo, I´m running a Gigabyte r9 280x rev. 2 Catalyst 13.12
My Settings:
I am getting exactly 304.7 kh/s
with the normal cgminer I am getting about 730 kh/s
My problem:
I really don´t know where the problem could be. Please help me
The rejection rate is a catastrophe!
My Settings:
Code:
color 02
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

My problem:
- It spits to many rejects out with an ratio of 12% (!!!). I tried playing with:
thread concurrency, no effect - 70% of 8192 = HW´s on mass
trying with -g 2 or higher was unsuccessful
lowering core clock resulted in lower hash speed (memclock the same)
lowering intensity induced lower hash speed
I really don´t know where the problem could be. Please help me
The rejection rate is a catastrophe!Problem solved. I changed the pool, now everything is running smooth!
