Catalyst and HD6670 OC Problem Tags: Graphics Cards Catalyst Overclocking Last response: July 11, 2012 8:56 AM in Overclocking Share satyamdubey Graphics card Expert July 11, 2012 6:53:01 AM Hello all, I have the following specs: Core i5 2400 4gb Corsair Value select 1333 Windows 7 32 bit ultimate Graphic card: Sapphire HD6670 with Catalyst 12.6 Issue: When I use AMD overdrive through catalyst and push the gpu clock beyond 800 MHz (900 max), the driver crashes and recovers (message: "AMD driver crashed and has successfully recovered") Everything works fine till 800 MHz (the base clock for the gpu) I have a 280 W psu which probably is undersized for my setup but everything works just fine with all components at their default settings. I went here http://support.amd.com/us/kbarticles/Pages/737-27116Rad... and it lists PSU and OC'ing(advises against it) as possible reasons why is there and OC'ing option in overdrive then??
