Notes:
1.
System memory configurations are based on availability and are subject to change.
2.
Interface does not support ULV/LV memory modulates or ULV/LV DIMMs.
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.
