System Agent Enhanced Intel SpeedStep® Technology

System Agent Enhanced Intel SpeedStep® Technology is a dynamic voltage frequency scaling of the System Agent clock based on memory utilization. Unlike processor core and package Enhanced Intel SpeedStep® Technology, System Agent Enhanced Intel SpeedStep® Technology has three valid operating points. When running light workload and SA Enhanced Intel SpeedStep® Technology is enabled, the DDR data rate may change as follows:

Before changing the DDR data rate, the processor sets DDR to self-refresh and changes the needed parameters. The DDR voltage remains stable and unchanged.

BIOS/MRC DDR training at maximum, mid and minimum frequencies sets I/O and timing parameters.

Note:Intel® System Agent Enhanced Speed Step® is not enabled for S-Processor 125W SKU
