No, the Softmenu III bios on my Abit NF7-S doesn't even go that low. It only goes as low as 2.6, which is what it sets as default for these modules. But by default it also sets the DRAM ratio to match the FSB (266 in this case) so I was wondering if it lowers the voltage by default like it lowers the bus speed. The bios only allows as high as 2.9v for the DRAM, in increments of 0.1 (total of 4 different options).
