System Memory Timing Support
The IMC supports the following DDR Speed Bin, CAS Write Latency (CWL), and
command signal mode timings on the main memory interface:
tCL = CAS Latency
tRCD = Activate Command to READ or WRITE Command delay
tRP = PRECHARGE Command Period
tRPb = per-bank PRECHARGE time
tRPab = all-bank PRECHARGE time
CWL = CAS Write Latency
Command Signal modes:
2N indicates a new DDR5/DDR4/LPDDR4x/LPDDR5/x command may be issued
every 2 clocks
1N indicates a new DDR5/DDR4/LPDDR4x/LPDDR5/x command may be issued
every clock.

SAGV Points
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: 1. 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
2. SA-GV modes
a. 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.
b. MedBW - Tuned for balance between power & performance.
c. HighBW Characterized by high power, low latency, moderate BW also used as RFI mitigation point.
d. MaxBW/ lowest latency Lowest Latency point, low BW and highest power.
3. Intel

is not enabled for S/S Refresh-Processor 125W/150W SKUs
4. SAGV point may change based on memory module Type.
5. On mixed module type configurations, the selected SAGV point will be the set to the lower frequency
configuration.
