2.1.2
System Memory Timing Support
The IMC supports the following DDR3 Speed Bin, CAS Write Latency (CWL), and
command signal mode timings on the main memory interface:
command signal mode timings on the main memory interface:
• t
CL
= CAS Latency
• t
RCD
= Activate Command to READ or WRITE Command delay
• t
RP
= PRECHARGE Command Period
• CWL = CAS Write Latency
• Command Signal modes = 1N indicates a new command may be issued every clock
• Command Signal modes = 1N indicates a new command may be issued every clock
and 2N indicates a new command may be issued every 2 clocks. Command launch
mode programming depends on the transfer rate and memory configuration.
mode programming depends on the transfer rate and memory configuration.
Note:
1.
Two Un-buffered DIMM Memory Configurations = 2N Command Mode at 1067/1333 MHz
2.
One Un-buffered DIMM Memory Configurations = 1N Command Mode at 1067/1333 MHz
3.
Both Channel A and B will run at same Command Mode based on the slowest mode enabled relative to the
memory configurations populated in both channels. For example, if Channel A has both DIMM connectors
populated (2N CMD Mode) and Channel B has only one DIMM connector populated (1N CMD Mode), then
2N CMD mode would be enabled for both channels.
4.
System Memory timing support is based on availability and is subject to change.
