Frequencies
The following table lists frequencies/voltages that appear to work well together, albeit with very conservative voltages. These are the values available in the app by default (thanks to kabaldan for corrections):
| Frequency (KHz) | vsel | Voltage (V) |
| 550000 | 56 | 1.3 |
| 600000 | 62 | 1.375 |
| 800000 | 68 | 1.45 |
| 1000000 | 74 | 1.525 |
| 1200000 | 80 | 1.6 |
The maximum vsel I could use was 127. The safe upper limit in the processor specs is 1.8V which translates to vsel 96 (according to wikidroid). Frequencies above 1250000 usually reboot spontaneously.
The community at android-hilfe has made extensive tests to find exactly what range of voltage selections could be used in each frequency. There are variations because not all Milestones are made equal, some can handle higher voltages and frequencies than others. Here is a copy of the table they produced, available here (thanks doc.payce!):
| max_vsel | |||
| Frequency | Stable (>=) | Possibly unstable | Probably unstable (<=) |
| 550 | 56 | ||
| 800 | 58 | 56 .. 54 | 52 |
