Catalyst Control Center Must Be Open for OC? Tags: Call of Duty Catalyst Overclocking Last response: November 16, 2010 2:46 PM in Overclocking Share shc37 November 11, 2010 2:04:14 AM I overclocked my 5550 via CCC. I was playing some CoD to test and noticed that the OC didn't register in ATI Overdrive. Is this normal or do I need to open CCC every time I boot up to have the overclock actually take?
