Hiya,
Ive been reading and lurking for a while now, and have finally got some bits together to set up a test rig.
My card of choice for the time being is a Sapphire 6970, (6990's arent available anywhere ive tried).
I have a weird problem that occurs for me in both Ubuntu and Centos installs (using the guides ive found on here).
If i setup poclbm to mine using the cpu, it works fine and chugs along at a measly 1200 khash/s, but if i then change the device to use the 6970 (detected as Cayman by poclbm) it works for a second or so, and then seems to lock up. The machine still reponds on command line in another session window, but trying to Ctrl-C the poclbm process fails to stop it unlike in cpu mode when it exits with "bye".
The drivers and sdk are all installed ok as shown by aticonfig;
[root@localhost ~]# aticonfig --odgc --adapter=all
Adapter 0 - AMD Radeon HD 6900 Series
Core (MHz) Memory (MHz)
Current Clocks : 250 150
Current Peak : 880 1375
Configurable Peak Range : [500-950] [1375-1450]
GPU load : 0%
[root@localhost ~]# aticonfig --odgt --adapter=all
Adapter 0 - AMD Radeon HD 6900 Series
Sensor 0: Temperature - 42.50 C
[root@localhost ~]# aticonfig --pplib-cmd "get fanspeed 0"
Fan speed query:
Query Index: 0, Speed in percent
Result: Fan Speed: 24%
When running poclbm, i get the following output before the process locks up and whilst the process is locked up i get the following weird output from aticonfig;
[root@localhost poclbm]# python2.7 poclbm.py -d0 --host=mining.eligius.st --port=8337 --user=[redacted] --pass=x --verbose -v -w128

As you can see, the temperature is very wrong for starters, can anyone give any pointers as to what could be wrong?
