How can i enable 1:1 FSB:RAM ratio in bios, on Gigabyte P35-DQ6? the lowest option is 2.5, and i need 2(gigabyte is a little confusing, they doubled ratios). Presing CTRL+F1 gives me only memory timings. I've tried everything. I don't see that anybody else has this problem. On every review of this motherboard they only set it to 2.0!!!it is shown there, and they don't touch anything!!!
