Electrical Characteristics R 11 Electrical Characteristics This chapter contains the MCH absolute maximum electrical ratings, power dissipation values, and DC characteristics. 11.1 Absolute Maximum Ratings Table 11-1 lists the MCH's maximum environmental stress ratings. Functional operation at the absolute maximum and minimum is neither implied nor guaranteed. Functional operating parameters are listed in the DC tables. Warning: Stressing the device beyond the "Absolute Maximum Ratings" may cause permanent damage. These are stress ratings only. Operating beyond the "operating conditions" is not recommended and extended exposure beyond "operating conditions" may affect reliability. Table 11-1.

Possible damage to the MCH may occur if the MCH temperature exceeds 150 °C. Intel does not guarantee functionality for parts that have exceeded temperatures above 150 °C due to specification violation. Intel® 82925X/82925XE MCH Datasheet 185
