Server Board Features
Hardware Requirements
To avoid integration difficulties and possible board damage, your system must meet the
requirements outlined below. For a list of qualified components, see the links under “
Additional
Information and Software .”
Processor
One or two Intel® Xeon™ processors with an 800MHz front side bus and a minimum of 2.8 GHz
frequency must be installed. The following table outlines the supported processors. For a complete
list of supported processors, see the links under “
Additional Information and Software .”
Table 4. Processor Support
Processor Family FSB Frequency Frequency
Intel® Xeon™ 800 MHz 2.8 GHz
Intel® Xeon™ 800 MHz 3.0 GHz
Intel® Xeon™ 800 MHz 3.2 GHz
Intel® Xeon™ 800 MHz 3.4 GHz
Intel® Xeon™ 800 MHz 3.6 GHz
Memory
The Server Board SE7520JR2 provides six DIMM sockets across two channels, Channel A and
Channel B. Channel A consists of DIMM sockets 1A, 2A, and 3A. Channel B consists of DIMM
sockets 1B, 2B, and 3B.
If six DIMMs are installed, the following maximum capacitites are possible:
ƒ For DDR266 DIMMS: Maxixmum capacity of 24GB
ƒ For DDR333 or DDR-2 400: Maximum capacity of 16 GB (DDR-2 400 on SE7520JR2SCSID2
and SE7520JR2SATAD2 only)
A minimum of one 256MB DIMM is required in DIMM socket 1A or 1B. This uses single-channel
interleave. However, for dual-channel interleave, providing optimum performance, a minimum of
two DIMMs should be installed in DIMM sockets 1A and 1B. Except for the option of installing a
single DIMM in socket 1A or 1B, DIMMs must be installed in pairs and populated as follows:
ƒ DIMM1A and DIMM 1B: Populate these two sockets together first
ƒ DIMM 2A and DIMM 2B: Populate these sockets in addition to DIMM 1A and DIMM 2A if
four DIMMs are to be used.
ƒ DIMM 3A and DIMM3B: Populate these sockets after DIMM 1A, DIMM1B, DIMM2A, and
DIMM2B have been populated.
