Thermal Specifications
Figure 6-2; Table 6-3 and Table 6-6) is indicative of a constrained thermal environment
(that is, 1U form factor). Because of the reduced cooling capability represented by this
thermal solution, the probability of TCC activation and performance loss is increased.
Additionally, utilization of a thermal solution that does not meet Thermal Profile B will
violate the thermal specifications and may result in permanent damage to the
processor. Intel has developed these thermal profiles to allow OEMs to choose the
thermal solution and environmental parameters that best suit their platform
implementation. Refer to the Dual-Core Intel® Xeon® Processor 5000 Series Thermal/
Mechanical Design Guidelines for details on system thermal solution design, thermal
profiles and environmental considerations.
The Dual-Core Intel Xeon Processor 5063 (MV) supports a single Thermal Profile
targeted at volumetrically constrained thermal environments (for example, blades, 1U
form factors.) With this Thermal Profile, it’s expected that the Thermal Control Circuit
(TCC) would only be activated for very brief periods of time when running the most
power-intensive applications. Refer to the Dual-Core Intel® Xeon® Processor 5000
Series Thermal/Mechanical Design Guidelines for further details.
The upper point of the thermal profile consists of the Thermal Design Power (TDP)
defined in Table 6-1, Table 6-4, Table 6-7 and the associated TCASE value. It should be
noted that the upper point associated with Thermal Profile B (x = TDP and y =
TCASE_MAX_B @ TDP) represents a thermal solution design point. In actuality the
processor case temperature will not reach this value due to TCC activation (refer to
Figure 6-1 and Figure 6-2). The lower point of the thermal profile consists of x =
P_profile_min and y = TCASE_MAX @ P_profile_min. P_profile_min is defined as the
processor power at which TCASE , calculated from the thermal profile, is equal to 50 °C.
The case temperature is defined at the geometric top center of the processor IHS.
Analysis indicates that real applications are unlikely to cause the processor to consume
maximum power dissipation for sustained time periods. Intel recommends that
complete thermal solution designs target the Thermal Design Power (TDP) indicated in
Table 6-1, Table 6-4 and Table 6-7, instead of the maximum processor power
consumption. The Thermal Monitor feature is intended to help protect the processor in
the event that an application exceeds the TDP recommendation for a sustained time
period. For more details on this feature, refer to Section 6.2. To ensure maximum
flexibility for future requirements, systems should be designed to the Flexible
Motherboard (FMB) guidelines, even if a processor with lower power dissipation is
currently planned. The Thermal Monitor feature must be enabled for the
processor to remain within its specifications.
