SAGV (System Agent Geyserville) is a way by which they SoC can dynamically scale the work point (V/F), by applying DVFS (Dynamic Voltage Frequency Scaling) based on memory bandwidth utilization and/or the latency requirement of the various workloads for better energy efficiency at System-Agent.heuristics are in charge of providing request for work points by periodically evaluating the utilization of the memory and IA stalls.

Notes: The Processor supports dynamic gearing technology where the Memory Controller can run at 1:1 (Gear-1, Legacy mode) or 1:2 (Gear-2 mode) and 1:4 (Gear-4 mode) ratio of DRAM speed. The gear ratio is the ratio of DRAM speed to Memory Controller Clock. MC Channel Width equal to DDR Channel width multiply by Gear Ratio SA-GV modes LowBW- Low frequency point, Minimum Power point. Characterized by low power, low BW, high latency. The system will stay at this point during low to moderate BW consumption. MedBW - Tuned for balance between power & performance. HighBW Characterized by high power, low latency, moderate BW also used as RFI mitigation point. MaxBW/ lowest latency Lowest Latency point, low BW and highest power. Intel® System Agent Enhanced Speed Step® is not enabled for S/S Refresh-Processor 125W/150W SKUs SAGV point may change based on memory module Type. On mixed module type configurations, the selected SAGV point will be the set to the lower frequency configuration.
