.
NOTE
DDR memory Two 72-bit DDR4
ports (64-bit data, 8-
bit ECC)
Each DDR4 port supports:
• Two 288-pin DIMM connectors, one supporting four chip selects and
other supporting two chip selects
• Single-/dual-/quad-rank, unbuffered/registered DDR4 memory
modules with 8-/16-bit data width
Quad rank is only supported if the second DIMM
connector of a DDR4 port is left unused.
NOTE
• 64-bit data and 8-bit ECC
• Data rates of up to 3.2 GigaTransfers/second (GT/s)
