ColorFire prepping custom Radeon HD 6870 for extreme overclocking

TechPowerUp reports ColorFire is working on a custom Radeon HD 6870 for extreme overclocking. The card offers a large cooling solution with heatpipes and a 110mm fan, and offers voltage measure points with cables, hardware-based voltage adjustment with DIP switches, dual-BIOS, and high-grade VRMs.

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.
