Thermal Specifications

5.1.2

Enhanced Thermal Management

ETM is a power and thermal protection feature. On the Dual-Core Intel Itanium

processor 9000 and 9100 series, ETM uses power and thermal sensing devices on the

die to monitor entry points, indicating dangerous operation exceeding the thermal or

power specification. Once the sensing devices observe the temperature rising above

the power or thermal entry point, the processor will enter a low power mode of

execution and notify the system by sending a Correctable Machine Check Interrupt

(CMCI). The processor will remain in this low power mode until the power and

temperature decrease below the entry points and remain there for approximately one

second, at which point it will send another CMCI and resume normal operation. If the

power and temperature cannot be reduced, and continue to rise to critical levels, the

processor will assert Power Trip or Thermal Trip. The ETM feature may be disabled

through the PAL.

5.1.3

Power Trip

The Dual-Core Intel Itanium processor 9000 and 9100 series protects itself and the

MVR from catastrophic over power by use of an internal power sensor. The sensor trip

point is set above the normal operating power to ensure that there are no false trips.

The processor will signal a continuable MCA when the power draw exceeds a safe

operating level.

Warning:

Data will be lost if the MVR overheats and shuts down as a result of an extended over

power condition.

Once power trip is activated, the processor can continue operation, but may continue to

signal continuable MCAs as long as the over power condition exists.

5.1.4

Thermal Trip

The Dual-Core Intel Itanium processor 9000 and 9100 series protects itself from

catastrophic overheating by use of an internal thermal sensor. The sensor trip point is

set well above the normal operating temperature to ensure that there are no false trips.

The processor will stop all execution when the junction temperature exceeds a safe

operating level.

Warning:

Data will be lost if the processor goes into thermal trip (signaled to the system by the

THRMTRIP# pin).

Once thermal trip is activated, the processor remains stopped until RESET# is asserted.

The processor case temperature must drop below the specified maximum before

issuing a reset to the processor. Please see Section 5.2 for details on case temperature.

5.2

Case Temperature

See Table 5-1 for the case temperature specifications for the Dual-Core Intel Itanium

processor 9000 and 9100 series. The case temperature is defined as the temperature

measured at the center of the top surface of the IHS.

Warning:

Data may be lost if the case temperature exceeds the specified maximum.
