Somewhat in the past, we wrote about AMD’s plans to present a revised version of HD6970/50 cards with uggraded PCB design. It was mainly the concern of power sub-system, which should feature Texas Instrument (TI) DrMOS elements instead of Voltera ones currently used. According to Aquacomputer news, it has recently received a AMD Radeon HD 6970 graphics cards with 2nd version of reference design.

As we see, the main difference is the power system. Now it has 6+1 phase circuit using different ICs though it is still hard to tell whether those are TI DrMos. Another thing to note is there is no Dual-BIOS switch. Apparently AMD does not like the opportunity of getting a “full-fledged” HD 6970 at a cost of HD 6950. A second revision of HD 6970/50 references boards will also means an upgrade for Aquagratix HD 6900 waterblock.

Aquacomputer is currently working on new water-blocks for revised PCB layouts of graphic cards mentioned above as well as a cooling solution for AMD’s new flagship HD6990 which is said to be the longest block in history of water-block production at Aquacomputer. More details should follow soon.
