Palit Radeon HD 4870 512MB Sonic Dual Edition Video Card Review

Overclocking

Please note that overclocking this card will void your warranty

Final Clock Speeds:

Core: 849Mhz
Memory: 1140Mhz (4560Mhz DDR)

Overclocking ATI cards these days is usually a lesson in futility since the Catalyst Control Center has extremely strict limits to exactly how far you can overclock. In this instance we used Rivatuner to push past the Catalyst limits and ended up with some pretty respectable overclocks. The core speed was increased almost 150Mhz over its bone stock speed while the memory really shone with an amazing 560Mhz overclock over Palit’s pre-overlcoked values.
