I replaced my 750W with an (oversized) 1000W PSU Bronze XIGMATEK and have still the exact same problem:Good GPU:
Code:
GPU 0: 270.1 / 284.3 Kh/s | A:3 R:0 HW:0 U:1.74/m I:20
76.0 C F: 36% (2125 RPM) E: 900 MHz M: 1250 Mhz V: 1.090V A: 99% P: 20%

Evil GPU:
Code:

I'm using the following CG miner command:
Code:
cd /opt/cgminer && rm -f *.bin && ./cgminer --scrypt --auto-fan \
--url $URL:$PORT --userpass $LTCUSER:$LTCPASS \
--thread-concurrency $THREAD_CONCURRENCY -I $INTENSITY \
--gpu-engine $GPU_ENGINE,$GPU_ENGINE \
--gpu-memclock $GPU_MEMCLOCK,$GPU_MEMCLOCK \
--gpu-powertune $GPU_POWERTUNE,$GPU_POWERTUNE \
--gpu-vddc $GPU_VDDC,$GPU_VDDC
with the following parameters:
Code:
INTENSITY=20 ; ## -I $INTENSITY
THREAD_CONCURRENCY=16384 ; ## --thread-concurrency $THREAD_CONCURRENCY
GPU_ENGINE=900 ; ## --gpu-engine $GPU_ENGINE
GPU_MEMCLOCK=1250 ; ## --gpu-memclock $GPU_MEMCLOCK
GPU_POWERTUNE=20 ; ## --gpu-powertune $GPU_POWERTUNE
GPU_VDDC=1.090 ; ## --gpu-vddc $GPU_VDDC
and of course:
Code:
export DISPLAY=:0 ;
export GPU_MAX_ALLOC_PERCENT=100 ;
export GPU_USE_SYNC_OBJECTS=1 ;
If I run each card separately then I get 580kH/s and combined a only get 524kH/s .. well at least I know now that is must be something else. But what?
