I'm trying to ascertain what voltage the Atom N270 runs from at various frequencies.
The values read from the IA32_PERF_STATUS register do not seem to correlate with the values in the table on page 20 of document: 320032-001 - Mobile Intel Atom Processor N270 Single Core Datasheet.
More so, the data available at http://processorfinder.intel.com suggests that the N270 has a VID voltage range of 0.9-1.1V, but at the maximum frequency, the status register reads the VID as 0x24, which, according to the table in that document is 1.05V. At the minimum frequency, the status register reads the VID as 0x0F, which isn't even in the table.
Can anyone help me out with this?
