NOTE 1: The blue blocks indicate that the DRAM Densities are supported but not validated.
NOTE 2: The grey blocks indicate that the DRAM Densities are supported and validated.
NOTE 3: 1DPC => One dimm per channel
 Supported DRAM Densities are 1Gb, 2Gb and 4Gb. Only 2Gb and 4Gb are validated
by Intel.
 Command Address Timing is 1N for 1DPC and 2N for 2DPC.
 Romley-EP/EX platform does not support 3DPC when using UDIMMs.

NOTE: The grey blocks indicate that the DRAM Densities are supported and validated.
 Physical Rank is used to calculate DIMM Capacity.
 Supported and validated DRAM Densities are 2Gb and 4Gb.
 Command Address Timing is 1N.
 The speeds are estimated targets and will be verified through simulation.
 For 3SPC/3DPC -Rank Multiplication (RM) >= 2.
 DDP -Dual Die Package DRAM stacking. P –Planer monolithic DRAM Die.
 Romley-EP/EX platform does not support 3DPC when using E5-2400 LRDIMMs.
