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 Intel® Xeon™ 800 MHz Intel® Xeon™ 800 MHz Intel® Xeon™ 800 MHz Intel® Xeon™ 800 MHz Intel® Xeon™ 800 MHz Frequency 2.8 GHz 3.0 GHz 3.2 GHz 3.4 GHz 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.
