AMD Opteron processors don't follow the Intel specifications.
|
||||
I'm going to "make up" 2.4 as the spec number for the Opterons.
|
||||
No good reason just a mnemonic for the 24x Opteron processor
|
||||
series.
|
||||
|
||||
Opteron VID encoding is:
|
||||
00000 = 1.550 V
|
||||
00001 = 1.525 V
|
||||
. . . .
|
||||
11110 = 0.800 V
|
||||
11111 = 0.000 V (off)
|
||||
|
||||
The 17 specification is in fact Intel Mobile Voltage Positioning -
|
||||
(IMVP-II). You can find more information in the datasheet of Max1718
|
||||
http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2452
|
||||
|
||||
The 13 specification corresponds to the Intel Pentium M series. There
|
||||
doesn't seem to be any named specification for these. The conversion
|
||||
tables are detailed directly in the various Pentium M datasheets:
|
||||
http://www.intel.com/design/intarch/pentiumm/docs_pentiumm.htm
|
||||
|
||||
The 14 specification corresponds to Intel Core series. There
|
||||
doesn't seem to be any named specification for these. The conversion
|
||||
tables are detailed directly in the various Pentium Core datasheets:
|
||||
http://www.intel.com/design/mobile/datashts/309221.htm
|
||||
|
||||
The 110 (VRM 11) specification corresponds to Intel Conroe based series.
