The DZ77BH-55K Media Series Desktop Board (Single Pack) from Intel is based on the Intel Z77 express chipset and is optimized for Intel K processors. It is an ideal board for gamers, overclockers and media enthusiasts alike. Equipped with Intel Visual BIOS*, this board satisfies all the needs of performance enthusiasts.

Intel Visual BIOS offers a graphical interface and animated controls that allow you to configure settings faster and take full advantage of your Intel K processor. It also allows easy overclocking of core, graphics and memory. The Intel Visual BIOS operates by your choice of touch screen, keys or mouse. All controls are literally at your fingertips, in a format you can visualize.

Advanced power and overclocking** capabilities of the DZ77BH-55K Desktop Board coupled with dramatic responsiveness improvements delivered by the Intel Smart Response technology provide the board of choice for gamers and media creation enthusiasts alike. Intel Smart Response technology provides SSD-like performance and brings up to 50% improvement in responsiveness as compared to an HDD-only system. The desktop board also includes other new responsiveness technologies such as Intel Rapid Start technology***, which allows you to quickly resume the system from sleep and standby modes.

Note: *Intel Visual BIOS may not be available at the launch of this product & may require BIOS update.
**Altering clock frequency or voltage may reduce system stability & life of the system & processor, cause the processor & other components to fail, reduce system performance, cause additional damage & affect system data integrity.
***BIOS update may be required to support Rapid Start technology. This feature may not be available at initial launch of product.
