5.3.1
DDR3 Main Memory
ATCA-7370 provides a dual Intel Xeon Processor E5-2648L CPU with Integrated Memory
Controller (IMC). Each IMC supports four independent 72-bit (64-bit Data + 8-bit ECC) wide
DDR3 memory channels.
ATCA-7370 supports one VLP DIMM sockets for each memory channel resulting in a total of
eight DDR3 DIMM sockets.
Supported DDR3 speeds are DDR3-800, DDR3-1066, DDR3-1333 and DDR3-1600. DDR3
signaling voltage level is 1.35 V/1.5 V. Higher DDR3 memory speed may be supported by the
next generation processor.
