NOTES:
1. Functionality is not guaranteed for parts that exceed Tdie temperature above 105C. Full performance
may be affected if the on-die thermal sensor is enabled. Please refer to the Montara Thermal Design
Guide for supplementary details.
2. Possible damage to the GMCH/MCH may occur if the GMCH/MCH temperature exceeds 150C. Intel
does not guarantee functionality for parts that have exceeded temperatures above 150C due to spec
violation.
6.2 Thermal Characteristics
The Intel 852GM/852GME/852GMV GMCH and Intel 852PM MCH is designed for operation at
die temperatures between 0°C and 105°C. The thermal resistance of the package is given in Table
49.
