Gigabyte GV-R927OC-2GD-GA

Overview

WINDFORCE™ 2X: Anti-turbulence Cooling
The special inclined dual fan design effectively minimizes the flow of turbulence between two fans and enhances heat dissipation of hot area right underneath each fan. By unique design, WINDFORCETM 2X even enlarges air channel on the graphics card vents and creates a more effective air flow system in chassis. This special design helps heat dissipate quickly from GPU. In addition, WINDFORCETM 2X is equipped with 2 copper heat-pipes which strengthen the speed of heat dissipation.
Ultra Durable VGA™
Features & Benefits
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.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.
