BTW - what are you people USING to make such high HASH power for Scrypt mining?
12 x ati 7950
using this:
#!/bin/sh
export DISPLAY=:0 GPU_MAX_ALLOC_PERCENT=100 GPU_USE_SYNC_OBJECTS=1
cd /home/darianc/cgminer
./cgminer \
--scrypt \
--failover-only \
--no-submit-stale \
--gpu-engine 1125,1150,1150 \
--gpu-memclock 1250,1250,1225 \
--shaders 1792 --thread-concurrency 16384 \
-w 256 --lookup-gap 2 -g 1 -I 19 \
--temp-target 80 --auto-fan --auto-gpu \
-o http://192.168.1.10:22222 -u darianc -p x -s 1
I tuned --gpu-engine and --gpu-memclock for each of the twelve cards over a few weeks.
They range from 1125 to 1150 and 1225 to 1250 respectively.
I have no voltage config due to running on xubuntu.
12 cards + 4 motherboards uses about 3800 watts in this config.
