does anyone have any information on converting voltage to vid (for use with linux-phc)?

I think one of the gui tools did it automatically. Also, older versions of phc understood the Pentium M voltages (the vids changed with the Core Duo). I believe there may have been a formula... if not, then the Intel datasheets have these huge tables matching vid to voltage.

where could I find one of these intel datasheets (for Pentium M)

actually, I'm rather confused about how to interperate the vid table. any help?

The formula is in thinkwiki, VID=(voltage-700)/16. Voltage in millivolts.
Oddly enough the table appears to be backwards?

I noticed that too. weird, huh?
so then 0.780v = ~5 vid?
edit: whoa, my windows voltages are way higher than my linux ones (minus the one @600mhz)
anyone know of any good stability tests to test cpu voltages for linux?

They should be the same, unless you're testing one of them wrong. I use prime95 on both.

i suppose that's a good point.
