ColorFire, the associate brand of Colorful that specializes in AMD Radeon-based graphics cards, today released a new Radeon HD 6870 card geared for extreme overclocking. Its design revolves around high-grade VRM, powerful cooling, and dual BIOS, each packing overclocked settings. The ColorFire Xstorm HD 6870 is a completely non-reference design card, the GPU is powered by a 5+1 phase VRM that uses POSCAP capacitors. The card uses two BIOS ROM chips that can be selected using a push-switch on the rear panel. The "normal" BIOS packs clock speeds of 940 MHz core and 1100 MHz (4.40 GHz effective) memory, while the "turbo" BIOS runs the card at 1050 MHz core, 1150 MHz (4.60 GHz effective) memory. The card is cooled by a large custom-design cooler the company earlier used on an HD 6850 card with similar design. It uses a large heat pipe-fed heatsink that is cooled by a 110 mm fan. Other overclocker-friendly features include consolidated voltage measure points with cables; and hardware-based voltage adjustment using DIP switches on the card. It draws power from two 6-pint power connectors. Display outputs include two DVI, and one each of full-size HDMI 1.4a, and DisplayPort 1.2. Colorfire will first sell the card in Asia, and then in Europe.
