NOTE:
1. Possible damage to the GMCH may occur if the GMCH temperature exceeds 150 °C. Intel
does not ensure functionality for parts that have exceeded temperatures above 150 °C due
to specification violation.
11.1.1
Current Consumption
Table 11-2 shows the current consumption for the MCH in the Advanced Configuration
and Power Interface (ACPI) S0 state. Icc max values are determined on a per-
interface basis, at the highest frequencies for each interface. Sustained current values
or Max current values cannot occur simultaneously on all interfaces. Sustained Values
are measured sustained RMS maximum current consumption and includes leakage
estimates. The measurements are made with fast silicon at 96 °C Tcase temperature,
at the Max voltage listed in Table 11-4. The Max values are maximum theoretical pre-
silicon calculated values. In some cases, the Sustained measured values have
exceeded the Max theoretical values.
