Hi Guys,

I had a HD 4870 for a couple of years and just upgraded to a HIS 2GB HD 6970.

When i put it in i got a freeze in windows (2d only) followed by: 'Driver has stopped responding and has restored' all the time.

I upgraded my Antec Trupower Trio PSU from a 550w to a 750w new one as i thought it was a power issue but it was not.

I did the whole, format, re-install windows 7 ultimate 64-bit, driver sweeper, safe mode, Stock clocks, original GFX drivers thing. No luck.

I finally seem to have resolved the issue (well it went from 3x crashes a day to none in 3 days)

Open Catalyst Control Center (CCC)
> Presets > Add Preset> (Name whatever you want) > enable AMD overdrive with stock or 'default' settings > Save profile

Go to c:\\users\\(windows profile)\\Appdata\\Local\\Ati\\ACE\\Profiles

Select the profile you just created (right click + edit)

I changed my 'Want_0' values only to a higher setting.

<Feature name="CoreClockTarget_0">
<Property name="Want_0" value="30000" />
<Property name="Want_1" value="50000" />
<Property name="Want_2" value="88000" />
</Feature>
<Feature name="PowerControl_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="MemoryClockTarget_0">
<Property name="Want_0" value="137500" />
<Property name="Want_1" value="137500" />
<Property name="Want_2" value="137500" />
</Feature>

Seems to have fixed the issue for now and still running OC'ed CPU with no issue. CCC v 11.6

Hope this might help someone.
