I just bought a ASUS HD6950 DirectCUII with 1GBDDR5. So you need more RAM to unlock the shaders do you? Damn I bought the cheaper one thinking I didn't need a that much RAM for mining.
I was looking on
https://en.bitcoin.it/wiki/Mining_hardware_comparison and ended here when searching for how to unlock the shaders.
At the moment i'm getting ~300kh/sec
Default Adapter - AMD Radeon HD 6900 Series
Core (MHz) Memory (MHz)
Current Clocks : 790 1250
Current Peak : 790 185
Configurable Peak Range : [600-950] [75-1350]
GPU load : 96%
chris@galaxy:~$ aticonfig --odgt
Default Adapter - AMD Radeon HD 6900 Series
Sensor 0: Temperature - 67.50 C
Voltage is 1.030
I am using AMDOverDriveCtrl and fan control is on auto and I am keeping the side of my case off for greater airflow. The card comes with dual fans some kind of direct ICU heatsink but it was getting really hot (about 79C) at 96% CPU just on the out of the box settings.
The way I am doing this at the moment is to try to keep the temp and voltage as low as possible and my belief is that if I keep the memory clock down I can get a high hash rate with a lower voltage. I set it to 185 in
AMD control panel but from aticonfig it might not really be this low.
What settings would you recommend?
Note: I have added a link to a screenshot of my AMD overdrive control panel below:

12/05/2011 14:03:40, long poll: Deepbit is temporarily unavailable

BadStatusLine: ''
Is it likely my GPU configuration causing these errors?
I first got one when I opened AMDcontrol panel and thought crap that voltage might be a bit high and then moved it down quite a bit. Never had any errors like that on my 5770 which while being excited about my badass new card I have a bit of nostalgia for as I got it up to 190m/hash a sec and it only required a thermaltake 430w PSU without any fancy 8pin connectors just one 6pin.
