Thermal Specifications Table 6-3. Quad-Core Intel® Xeon® Processor X5400 Series Thermal Specifications Core Frequency Launch to FMB Thermal Design Power (W) 120 Minimum TCASE (°C) 5 Maximum TCASE (°C) Notes See Figure 6-2; Table 6-4; 1, 2, 3, 4, 5 Table 6-5 Notes: 1. These values are specified at VCC_MAX for all processor frequencies. Systems must be designed to ensure the processor is not to be subjected to any static VCC and ICC combination wherein VCC exceeds VCC_MAX at specified ICC. Please refer to the loadline specifications in Section 2.13.1. 2. Thermal Design Power (TDP) should be used for the processor thermal solution design targets. TDP is not the maximum power that the processor can dissipate. TDP is measured at maximum TCASE. 3. These specifications are based on silicon characterization. 4. Power specifications are defined at all VIDs found in Table 2-3. The Quad-Core Intel® Xeon® Processor X5400 Series may be shipped under multiple VIDs for each frequency. 5. FMB, or Flexible Motherboard, guidelines provide a design target for meeting all planned processor frequency requirements. Figure 6-2. Quad-Core Intel® Xeon® Processor X5400 Series Thermal Profiles A and B TCASE_MAX is a thermal solution design point. In actuality, units will not significantly exceed TCASE_MAX_A due to TCC activation. 75 70 65 Tcase [C] 60 Thermal Profile B Y = 0.221*x + 43.5 55 50 Thermal Profile A Y = 0.168*x + 42.8 45 40 0 10 20 30 40 50 60 70 80 90 100 110 120 Pow er [W] Notes: 1. Thermal Profile A is representative of a volumetrically unconstrained platform. Please refer to Table 6-4 for discrete points that constitute the thermal profile. 2. Implementation of the Quad-Core Intel® Xeon® Processor X5400 Series Thermal Profile A should result in virtually no TCC activation. Furthermore, utilization of thermal solutions that do not meet Thermal Profile A will result in increased probability of TCC activation and may incur measurable performance loss. (See Section 6.2 for details on TCC activation). 3. Thermal Profile B is representative of a volumetrically constrained platform. Please refer to Table 6-5 for discrete points that constitute the thermal profile. 4. Implementation of the Quad-Core Intel® Xeon® Processor X5400 Series Thermal Profile B will result in increased probability of TCC activation and measurable performance loss. Furthermore, utilization of thermal solutions that do not meet Thermal Profile B do not meet the processor's thermal specifications and may result in permanent damage to the processor. 5. Refer to the Quad-Core Intel® Xeon® Processor 5400 Series Thermal/Mechanical Design Guidelines (TMDG) for system and environmental implementation details. 83
