Intel® Server Board S1200SP Family Technical Product Specification
19
Notes:
1. No support for RDIMMs.
2. No support for SODIMM.
3. All channels in a system run at the fastest common frequency.
4. Mixing ECC and non-ECC UDIMMs anywhere on the platform is not supported.
5. Static CLTT supported using BMC (requires ECC DIMMs with thermal sensor).
3.3.1.1 Memory Population Rules
Note: Although mixed DIMM configurations are supported, Intel
®
only performs platform validation on
systems that are configured with identical DIMMs installed.
The processor provides two channels of memory, each capable of supporting up to two DIMMs.
• DIMMs are organized into physical slots on DDR4 memory channels that belong to processor socket.
• The silk screened DIMM slot identifiers on the board provide information about the channel. For example,
DIMM_A1 is the first slot on Channel A on processor.
• Channel A and Channel B are independent and are not required to have the same number of DIMMs
installed. Either channel may be used for a single-DIMM configuration.
• When only one memory channel is populated, the memory runs in Single Channel mode, with no
interleaving.
• When using one or two memory modules, populate the farthest slot in the channel. On Intel® Server Board
S1200SP, the farthest slot in the channels are A2 and B2 with blue connectors.
On the Intel
®
Server Board S1200SP, a total of 4 DIMM slots is provided. The nomenclature for DIMM
sockets is detailed in the following table.
