description : The SAPPHIRE HD 7970 6GB Vapor-X Edition shares many of the features of the recently announced industry-leading Vapor-X Edition. SAPPHIRE’s innovative Vapor-X cooling technology allows products to run not only cooler but also much quieter. A Vapor-X product means a virtually silent gaming experience and more headroom to explore performance tweaking! On its standard settings, the SAPPHIRE HD 7970 6GB Vapor-X Edition runs at 1000 MHz and with PowerTune Dynamic Boost rises to 1050 MHz on the engine with the memory clock at 6000 MHz effective. When the Dual BIOS button is operated, the core clock speed is raised to 1050 MHz with PowerTune Dynamic Boost to 1100 MHz on the engine. The fan profile and PowerTune limit is also changed to performance settings. In addition, users will be able to individually tune the card with SAPPHIRE TriXX, the company’s free to download software tool that allows key parameters to be adjusted for maximum performance.
