5: System Serverboard Information

Memory Support

The serverboard supports DDR3-1333/1066/800 registered SDRAM. Only interleaved memory is

supported, so you must equally populate DIMM slots for optimal functionality (see the

subsections “Memory DIMM Layout” on page 34 and “Memory DIMM Functionality

Guidelines” on page 39).

Populating four slots at a time with memory modules of the same size and type (single or

dual-rank) will result in interleaved (128-bit) memory, which is faster than non-interleaved

(64-bit) memory. See Table 5-1 on page 35 and Table 5-2 on page 37.

To remove a DIMM module, use your thumbs to gently push the release tabs near both ends of the

module (see Figure 5-4). This should release it from the slot.

Memory DIMM Layout

Each C2112-4G3 serverboard memory bus is a controller array intended for use with one or two

processor configurations. Note that memory DIMM slots should be populated equally in adjacent

memory banks on each channel for optimal performance.
