ATCA-9405 Installation and Use (6806800M71G) 73
The DDR3 memory interface runs at a maximum frequency of 400 MHz providing a total
bandwidth of 6.4 GBps. The fastest supported DDR3 speed is DDR3-800 (PC3-6400).
4.4.2 Memory Socket
A Very Low Profile (VLP) DDR3 DIMM socket is provided to install of-the-shelf DIMM modules.
The socket is keyed for DDR3 DIMM modules using 1.5V supply voltage.
4.4.3 Memory Modules
ATCA-9405 requires VLP DDR3 DIMM modules in order to fit within the maximum component
height profile of an ATCA blade. Installed module height must not exceed 21.33 mm above PCB
surface.
