Gainward is throwing its hat into the non-reference HD 4870 ring, further to PowerColor's contribution, which we reported on last week.

According to this report from Expreview, Gainward's own offering will feature, an interesting, dual-BIOS functionality.

The first BIOS, set for default clocks, will find the GPU at 750 MHz and the GDDR5 memory, at 950 MHz (QDR). The second BIOS, also known as the overclock BIOS, will boast GPU clocks of 775 MHz and GDDR5 memory clocks, of 1000 MHz (QDR).

The cooling solution aims to keep the thermals of this RV770 powered part under control, by utilising a dual fan setup. A 4-phase VRM will address power delivery requirements for overclocking and, will also revel in having the smaller of the two fans, tending to its every cooling whim.

Gainward's non-reference HD 4870 solution is expected to be available in September at an, as yet, undisclosed price.
