Features
7.4.3.3.6 MINV: Minimum Core Voltage
This location contains the minimum Processor Core voltage. This field, rounded to the
next thousandth, is in mV and is reflected in hex. The minimum V
CC
reflected in this
field is the minimum allowable voltage assuming the FMB maximum current draw.
Writes to this register have no effect.
Note: The minimum core voltage value in offset 21 - 22h is a single value that assumes the
FMB maximum current draw. Refer to Table 2-10 and Table 2-11 for the minimum core
voltage specifications based on actual real-time current draw.
Example: A voltage of 1.000 V minimum core voltage would contain 03E8h (1000
decimal) in Offset 21 - 22h.
7.4.3.3.7 TCASE: T
CASE
Maximum
This location provides the maximum T
CASE
for the processor. The field reflects
temperature in degrees Celsius in hex format. This data can be found in Section 6. The
thermal specifications are specified at the case Integrated Heat Spreader (IHS).Writes
to this register have no effect.
Example: A temperature of 66C would contain 42h (66 decimal) in Offset 23h.
7.4.3.3.8 PCDCKS: Processor Core Data Checksum
This location provides the checksum of the Processor Core Data Section. Writes to this
register have no effect.
7.4.3.4 Cache Data
This section contains cache-related data.
