UltraSPARC IIIi CPU core voltage

[Julian Coleman <jdc%coris.org.uk@localhost>]

Hi,

Looking at the envstat output on my U45, there are 2 voltage entries at
1.490v and 1.498v, plus 2 at 1.238v and 1.232v.  On the V245, I see CPU
core voltages of 1.443v and 1.459v with a CPU speed of 1504 Mhz.  On the
U45, the CPU speed is 1600 MHz, so do the 1.49v readings represent the
core voltage?  I see from online docs that the inital 1280 Mhz version
has a core voltage of 1.4v [1], but a later version (up to 1800 Mhz)
has a core voltage of 1.2v [2].  Any thoughts or information welcome!

Why am I asking?  I was just curious to put names to the various sensor
readings.

Regards,

Julian
