Processors
The T5520UR server board accommodates two six-core processors from the Intel® Xeon®
processor 5600 series. These processors can be ordered from Kontron using the Kontron
part numbers listed in the
CG2100 Carrier Grade Server Configuration Guide
.
Memory
The Intel® QuickPath Memory Controller integrated in the Xeon 5600 processor supports
DDR3 800, DDR3 1066 and DDR3 1333 memory technologies. The memory controller supports
both registered DIMMs (RDIMMs) and unbuffered DIMMs (UDIMMs). RDIMMs must be ECC only,
while UDIMMs can be ECC or non-ECC. RDIMMs and UDIMMs cannot be mixed. ECC and non-ECC
UDIMMs can be mixed, but the presence of a single non-ECC UDIMM disables ECC
functionality.
The T5520UR server board supports six DDR3 memory channels (three per processor
socket) with two DIMMs per channel, thereby supporting up to 12 DIMMs and a 96GB
maximum memory capacity when two processors are installed. Memory modules of mixed
speed are supported by automatic selection of the highest common frequency of all
memory modules.
