Gigabyte Gtx 770

EW WINDFORCE 3X 2 SLOT 450W cooling system Keeping the same 450W Cooling capacity using only 2 slots, the New WINDFORCE 3X 450W cooling system is equipped with two 8mm and four 6mm cooper heat-pipes , inclined fans, and GIGABYTE “Triangle Cool” technology. This not only provides an effective heat dissipation capacity but GPU Boost 2.0 technology also enables higher performance due to a lower temperature. OC GURU ll Brand-new instinctive user interface, easier to monitoring and adjusting all important settings. Users can set up MONITORING, GPU CLOCK, MEMORY CLOCK,FAN, OSD, ONLINE SUPPORT and update driver, BIOS directly. Ultra Durable VGA™ Lower GPU Temperature Ultra Durable VGA board provides dramatic cooling effect on lowering both GPU and memory temperature by doubling the copper inner layer of PCB. Better Overclocking Capability Ultra Durable VGA board reduces voltage ripples in normal and transient state, thus effectively lowers noises and ensures higher overclocking capability. Decrease Power Switching Loss Ultra Durable VGA board allows more bandwidth for electron passage and reduces circuit impedance. The less circuit impedance, the more stable flow of current and can effectively improve power efficiency. 4GB for Multi-Screen HD solution On board 4GB of GDDR5 memory, satisfying your multi-screen setup, high definition and extreme gaming experience. 8-Phase power Design Compare to reference 6-phase power design, GV-N770OC-4GD V2.0 makes the MOSFET working at a lower temperature and provides more stable voltage output. Besides, over temperature protection and load balance to each MOSFET can effectively extend the card life.
