Memory throttling is a feature of the Intel
®
5400 Chipset to prevent FBDIMM memory from
overheating. If the performance of the installed FBDIMMs approaches their supported thermal
limit for a given platform, the system BIOS initiates memory throttling. This manages memory
performance by limiting bandwidth to the DIMMs, therefore capping the power consumption and
preventing the DIMMs from overheating.
Two different memory throttling mechanisms are supported on this server board:
Closed Loop Thermal Throttling (CLTT)
Open Loop Throughput Throttling (OLTT)
The system BIOS determines which mechanism to implement based on the following flow chart:
