6.4.7.1
Processor Part Number
Offset 56h-5Ch contains seven ASCII characters reflecting the Intel part number for the
processor. This information is typically marked on the outside of the processor. If the
part number is less than 7 characters, a leading space is inserted into the value.
processor. This information is typically marked on the outside of the processor. If the
part number is less than 7 characters, a leading space is inserted into the value.
Example: A processor with a part number of 80546KF will have data as 46h, 4bh, 36h,
34h, 35h, 30h, 38h starting at offset 56h.
34h, 35h, 30h, 38h starting at offset 56h.
6.4.7.2
Processor Electronic Signature
Offset 5Dh-64h contains a unique 64-bit identification number.
6.4.7.3
Base Frequency (Core)
Offset 65h-66h contain a bcd representation of core base frequency.
Example: A processor with a core base frequency of 1600 MHz will have data as 00, 16
starting at offset 65h.

Thermal Reference Data
6.4.8.1
Recommended Thermalert Hot Assertion Byte
Offset 6Bh contains the thermalert threshold expressed as the number of degrees C
below the PROCHOT_N (thermal throttling) temperature in hex format.
below the PROCHOT_N (thermal throttling) temperature in hex format.
6.4.8.2
Recommended Thermalert Hot De-assertion Hysteresis
The de-assertion threshold is expressed as the number of degrees C below the
thermalert hot threshold value in hex format.
thermalert hot threshold value in hex format.
Example: reading offset 6Bh=00001010 and 6Ch=0000010, then programming the
CSRs with these values means THERMALERT_N will be asserted when junction
temperature rises to 10C below the PROCHOT_N (thermal throttle) threshold and will
remain asserted until the junction temperature drops to 12C below the PROCHOT_N
threshold.
CSRs with these values means THERMALERT_N will be asserted when junction
temperature rises to 10C below the PROCHOT_N (thermal throttle) threshold and will
remain asserted until the junction temperature drops to 12C below the PROCHOT_N
threshold.
6.4.8.3
Thermal Design Power
Offset 6Dh is programmed with 2 hex digits representing the max TDP of the part.
Example: 6Dh = 0xB9 indicates a 185 W part.
6.4.8.4
TControl
Offset 6Eh contains the recommended TControl spec in degrees C below PROCHOT_N
temperature in hex format.
