2 | The cpufreq-nforce2 driver changes the FSB on nVidia nForce2 plattforms. | ||
3 | |||
4 | This works better than on other plattforms, because the FSB of the CPU | ||
5 | can be controlled independently from the PCI/AGP clock. | ||
6 | |||
7 | The module has two options: | ||
8 | |||
9 | fid: multiplier * 10 (for example 8.5 = 85) | ||
10 | min_fsb: minimum FSB | ||
11 | |||
12 | If not set, fid is calculated from the current CPU speed and the FSB. | ||
13 | min_fsb defaults to FSB at boot time - 50 MHz. | ||
14 | |||
15 | IMPORTANT: The available range is limited downwards! | ||
16 | Also the minimum available FSB can differ, for systems | ||
17 | booting with 200 MHz, 150 should always work. | ||
