Mining Rig Problems (HD6950)
Bevor I start complaining and describing what my problem is, I would like to point out, that I tried it myself
1 week and with help of my friend google!
My problem is that my graphic cards are running to hot (83°C+) but only make 270 khash/s each with the
following hardware setup:
1x AMD Sempron 140
1x Asrock 970 Extreme4 Mainboard
2x Sapphire Radeon HD6950 1GB (Shaders unlocked)
1x Sapphire Radeon HD6950 2GB (shaders locked, but working on it)
I’m running on XUbuntu with the following setup:
./cgminer --scrypt -I 18 --thread-concurrency 8192 --gpu-engine 900 --gpu-memclock 1000 --temp-target
80 --auto-fan -o xxxx -u xxxx -p xxxx
A few forum threads say that this card could be get to 450 khash/s+ and that would be nice to achieve!
I hope you can help me!
