Overclocking a Graphic card Tags: CPUs Default Overclocking Graphics Cards Last response: December 18, 2009 2:35 PM in Overclocking Share Nilushan December 18, 2009 2:33:26 PM I have an HIS 4650 512MB Graphic card. I overclocked it from the Catalyst Control Center. GPU Clock - Default=600 OCed @ = 700 Memory Clock - Default=500 Not Oced When i play Battlefield 2 on default settings it runs fine. But when i overclock it even a little bit, it lags. And i run 3DMark Vantage. Upto 700 on the GPU clock it runs fine. But when i increase more everything gets stuck. Why? And this card doesnt have a fan. Instead it has a Zalman isilence4 heatsink. In Catalyst Control Center it shows that a fan is working. And it even shows the fan speed %. Why?
