E7500 MCH Thermal and Mechanical Design Guidelines
5.2 Power Simulation Software
The power simulation software is a utility designed to dissipate the thermal design power on a
MCH when used in conjunction with an Intel
®
Xeon™ processor with 512-KB L2 cache. The
combination of the Intel
®
Xeon™ processor with 512-KB L2 cache and the higher bandwidth
capability of the E7500 chipset enables new levels of system performance. To assess the thermal
performance of an MCH thermal solution under “worst-case realistic application” conditions, Intel
has developed a software utility that operates the chipset at near worst-case power dissipation.
The utility has been developed solely for testing customer thermal solutions at near the thermal
design power. Figure 7 shows a decision flowchart for determining thermal solution needs. Real
future applications may exceed the thermal design power limit for transient time periods. For
power supply current requirements under these transient conditions, refer to each component’s
datasheet for the I
CC
(Max Power Supply Current) specification. Contact your Intel Field Sales
representative to obtain a copy of this software.
