32 Getting Started3.3 Installing Memory ModulesThe EAM-400H supports up to 16 GB of DDR3 1066/1333 MHz(2nd Gen Intel® Core™) or 1333/1600 MHz (3rd Gen Intel®Core™) memory modules in two DIMM sockets. A DDR3 modulehas a 240-pin footprint compared to the legacy 184-pin DDRDIMM. DDR3 modules are notched to facilitate correct installationin the DIMM sockets and prevent installation of DDR2 or DDRmodules.Disconnect all power to the board before installing a memorymodule to prevent damaging the board and memory module.WARNING:Memory Configuration OptionsThe EAM-400H supports 1GB, 2GB, 4GB and 8GB unbufferednon-ECC DDR3 DIMMs in the following configurations:► Channel A: DIMM_A1Channel B: DIMM_B1► For dual-channel configuration, the total size of memorymodule installed per channel must be the same(DIMM_A1 = DIMM_B1).► It is recommended that you install DIMMs with the sameCAS latency. For maximum compatibility, install memorymodules with the same brand, model, and/or rating.
