Info). The following sections give an overview of the memory system.
Intel® QuickPath Memory
The Intel® QuickPath Interconnect is a high-speed, packetized, point-to-point interconnect that offers
much higher bandwidth with low latency. It has a snoop protocol optimized for low latency and high
scalability, as well as packet and lane structures enabling quick completions of transactions. Reliability,
availability, and serviceability features (RAS) are built into the architecture.
Integrated Memory Controller (IMC) and Memory Subsystem.
A memory controller is integrated into the processor. Each processor provides four DDR3 channels that
support the following features.
•
Both registered DIMMs (RDIMMs) and unbuffered DIMMs (UDIMMs)
•
LR DIMM (Load Reduced DIMM) for buffered memory solutions demanding higher capacity
memory subsystems
•
Independent channel mode or lockstep mode
•
Memory DDR3 data transfer rates of 800, 1066, 1333, and 1600 MT/s
•
64-bit wide channels plus 8 bits of ECC support for each channel
For detailed information about additional features supported, see Section 3.2.2, “Integrated Memory
Controller (IMC) and Memory Subsystem” in the Intel® Server Board S2600C) Family TPS.
3.3.2 Supported Memory
The Intel® Server Board S2600CO supports eight DDR3 memory channels (four per processor socket)
with two DIMM slots per channel. Up to 16 DIMMs can be used with dual-processor sockets giving a
maximum memory capacity of 256 GB.
The server board supports DDR3 800, DDR3 1066, DDR3 1333, and DDR3 1600 memory transfer rates.
Memory modules of mixed speed are supported by automatic selection of the highest common frequency
of all memory modules.
For detailed information about UDIMM, RDIMM and LRDIMM support guidelines, see Section 3.2.2.1,
“Supported Memory” in the Intel® Server Board S2600CO Family TPS.
Memory Map and Population Rules

NOTE: Although mixed DIMM configurations may be functional, platform validations are performed only on
systems configured with identical DIMMs.
