Quad-Core Intel® Xeon® Processor 5300 Series Datasheet 95
Thermal Specifications
Notes:
1. Please refer to Table 6-9 for discrete points that constitute the thermal profile.
2. Refer to the Quad-Core Intel® Xeon® Processor 5300 Series Thermal/Mechanical Design Guidelines for 
system and environmental implementation details.

Table 6-10.Quad-Core Intel® Xeon® Processor L5318 Thermal Specifications
Notes:
1. These values are specified at V
CC_MAX
 for all processor frequencies. Systems must be designed to ensure 
the processor is not to be subjected to any static V
CC
 and I
CC
 combination wherein V
CC
 exceeds V
CC_MAX
 at 
specified I
CC
. Please refer to the loadline specifications in Section 2.
2. Maximum Power is the highest power the processor will dissipate, regardless of its VID. Maximum Power is 
measured at maximum T
