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.
