Server Board S2400BB Memory Slot Layout
The following are DIMM population requirements.
All DIMMs must be DDR3 DIMMs
Unbuffered DIMMs can be ECC or non-ECC. However, Intel only validates and supports ECC memory
for its server products.
Mixing of Registered and Unbuffered DIMMs is not allowed
Mixing of LRDIMM with any other DIMM type is not allowed
Mixing of DDR3 voltages is not validated within a socket or across sockets by Intel. If 1.35V (DDR3L)
and 1.50V (DDR3) DIMMs are mixed, the DIMMs will run at 1.50V.
Mixing of DDR3 operating frequencies is not validated within a socket or across sockets by Intel. If
DIMMs with different frequencies are mixed, all DIMMs will run at the common lowest frequency.
Quad rank RDIMMs are supported but not validated by Intel.
A maximum of 8 logical ranks (ranks seen by the host) per channel is allowed.
Mixing of ECC and non-ECC DIMMs is not allowed per platform. Intel does not support non-ECC
memory in its server products.
DIMMs with different timing parameters can be installed on different slots within the same channel, but
only timings that support the slowest DIMM will be applied to all. As a consequence, faster DIMMs will be
operated at timings supported by the slowest DIMM populated.
When one DIMM is used, it must be populated in the BLUE DIMM slot (farthest away from the CPU) of a
given channel.
