Dual-Core Intel® Xeon® Processor 7100 Series Datasheet 101
Features
Example: For a Dual-Core Intel Xeon processor 7100 series the minimum voltage is
0.991 V = 1.100 V (Min VID) - 0.209 V (Voltage Offset at maximum current). Offset 21
- 22h would contain 03DFh (0991 decimal).
7.4.3.3.8 TCASE: T
CASE
Maximum
This location provides the maximum T

temperature in degrees Celsius in hex format. This data can be found in the Tab l e 6-1 .
The thermal specifications are specified at the case Integrated Heat Spreader
(IHS).Writes to this register have no effect.
7.4.3.3.9 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.
