AMD Revising Radeon HD 6900 Series PCB

AMD is planning a revised Radeon HD 6900 series reference-design PCB. It is reported that the delays which short-supply of TI-made driver-MOSFETs caused have been tided over with, giving AMD the opportunity to redesign the PCB to make use of the more cost-effective yet high-performance VRM circuitry. AMD is reported to have used expensive Volterra-made digital PWM chippery in a last-ditch effort to release the Radeon HD 6900 series in time for the X'mas shopping season, after TI-made VRM components couldn't make it to foundry-partners in time (which caused the launch delay in November, 2010). The redesigned PCB with its new TI-made driver-MOSFETs (DrMOS) could also present an opportunity for AMD to patch the Radeon HD 6950, making stream processor unlocking using BIOS flash impossible, notes the source. This development surfaced after water-cooling major Swiftech announced that it delayed the launch of its Radeon HD 6900 series full-coverage water block because AMD is revising its PCB design.

If it's Jan 22, then you will really need luck, I think.

*edit* Oh, it was not you, siqueirah:o Sorry, I misread.

Yup, maybe I'll just stick with the old $240 HD6870 =X

Anyone here try to solder the two pins on the 6950 power supply so you can convert to a 8 pin connector.

I just looked at the front and back high res pictures of the 6970 and 6950, and I think you would be able to do that quite easily. The PCBs look identical, save for some different looking DP connectors and the random marking here and there.

I was wondering about that because the 2900 pro had a 8 pin connector and I only have 2x6 pin, so I connected 2 more grounds which allowed me to use the ati over drive. Theirs discussion here that the 2 pins to be added might just be grounds, but if someone here has a 6970 they could take a voltage reading for me and let me know what they get, I'll do the rest.
I tried the bios mod and am wondering if we can do another mod just to fool the card into thinking it is a 6970 so it doesn't increase the voltage but allows a 6950 to go past the 840 & 1325 constraint. When I mod to a 6970 my temps idle at about 60c instead of around 40c.
I tried a driver that came out later then the 14 of Dec, seemed to take care of the higher temps.

True, would be great if we could get a 6970 owner to do take these readings.

Anyone knows when 2nd batch is releasing? Cause my supplier say currently no stock, stock will come in on Tuesday (11/1/2011), so wondering if that is the new stock or the old stock.
