•

Up to two server board processors

•

Up to 96 GB of DDR3 memory

•

Up to eight SAS/SATA hard disk drives

•

Up to five PCI add-in cards consuming a maximum of 25W for each full-height PCI-

X/PCIe add-in card and 10W for each low-profile PCIe add-in card.

The cooling subsystem meets acoustic and thermal requirements at the lower fan speed

settings. At the higher fan speed settings, thermal requirements are met for the

maximum ambient temperatures, but acoustic requirements are not met.

2.14 Processors and Memory DIMMs

NOTE: To avoid integration difficulties and possible board damage, your server must

meet the requirements outlined below. For a list of qualified processors refer to

the Configuration Guide located on the support website at

(search for NSN2U, click on Product Downloads,

then Ordering Guide). For a list of qualified DIMMs refer to the Tested Memory

Processors

The T5520UR server board accommodates two quad-core processors from the Intel® Xeon®

processor 5500 series. These processors can be ordered from Kontron using the Kontron

part numbers listed in the IP Network Server NSN2U Configuration Guide.

Memory

The Intel® QuickPath Memory Controller integrated in the Xeon 5500 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.
