Great, I too have the Ultra Durable GDDR3 version of the Gigabyte 3870 (GV-RX387512H) and was looking for a solution to raise the low stock voltage and to get over the clock lock. Currently, my card is at 850/1025Mhz (855/1031Mhz) with the stock BIOS. Any higher on the RAM and I can see yellow artefacts in ATI Tool's Artefact Finder, although these are not detected. Overdrive in CCC gives a blank screen with the core at or above 865Mhz.

Is there no solution to modify the stock BIOS to get higher voltage and to remove the clock lock?
