A minimum of one 512 MB FBDIMM is required in DIMM socket DIMM_A1. FBDIMMs must meet the following requirements: • Use only FBDIMMs (DDR2-533 or DDR2-667). • Use only 240-pin FBDIMMs. • Use FBDIMMs with capacities of 512 MB, 1 GB, 2 GB, or 4 G. • Use only FBDIMMs that comply with the JEDEC Rev 2.0 specifications. • FBDIMMs in a given channel must be identical with respect to manufacturing, speed, timing, and organization. For example, this means the FBDIMMs in sockets A1 and B1 must be identical, and the FBDIMMs in sockets C1 and D1 must be identical. FBDIMMs in adjacent sockets on the same channel do not need to be identical. The server will run in single-channel mode under the following conditions: • Only a single FBDIMM is installed. This FBDIMM must be in socket DIMM_A1. • The population of socket DIMM_A1 determines the mode that is selected. If DIMM_A1 and DIMM_B1 are not identical, then the system reverts to singlechannel mode and DIMM_B1 is disabled. • If the FBDIMMs in socket positions on adjacent channels of the branch are different in terms of timing, technology, or size. If the FBDIMMs on adjacent channels of a branch are not identical, the FBDIMM on the higher channel is disabled. • If Branch 0 cannot support the dual-channel mode of operation for any reason, the server will run in single-channel mode. For dual-channel interleave, providing optimum performance, a minimum of two FBDIMMs must be installed. Populate FBDIMMs of the same size in each channel. Install these FBDIMMs in DIMM sockets DIMM_A1 and DIMM_B1. For dual-channel interleave, FBDIMMs must be installed in pairs and populated as follows: • DIMM_A1 and DIMM_B1: Populate these two sockets together first. • Populate FBDIMMs in channel order, populating all FBDIMMs in each channel. For example, if four FBDIMMs are to be installed, they need to be in sockets A1, B1, C1, and D1. • The minimum memory population for enabling Branch 1 is four FBDIMMs: DIMM_A1, DIMM_B1, DIMM_C1 and DIMM_D1. During the boot process, FBDIMMs that do not meet the population requirements are disabled. For a complete list of supported memory FBDIMMs, see the links under "Additional Information and Software" on page viii Power Supply A minimum of 550 watts is required. Your power supply must provide a minimum of 3 amps of 5-volt standby current or the server will not boot. 18 Intel® Server Board S5000PSL

A minimum of one 512 MB FBDIMM is required in DIMM socket DIMM_A1.
FBDIMMs must meet the following requirements:
•
Use only FBDIMMs (DDR2-533 or DDR2-667).
•
Use only 240-pin FBDIMMs.
•
Use FBDIMMs with capacities of 512 MB, 1 GB, 2 GB, or 4 G.
•
Use only FBDIMMs that comply with the JEDEC Rev 2.0 specifications.
•
FBDIMMs in a given channel must be identical with respect to manufacturing,
speed, timing, and organization. For example, this means the FBDIMMs in sockets
A1 and B1 must be identical, and the FBDIMMs in sockets C1 and D1 must be
identical. FBDIMMs in adjacent sockets on the same channel do not need to be
identical.
The server will run in single-channel mode under the following conditions:
•
Only a single FBDIMM is installed. This FBDIMM must be in socket DIMM_A1.
•
The population of socket DIMM_A1 determines the mode that is selected. If
DIMM_A1 and DIMM_B1 are not identical, then the system reverts to single-
channel mode and DIMM_B1 is disabled.
•
If the FBDIMMs in socket positions on adjacent channels of the branch are different
in terms of timing, technology, or size. If the FBDIMMs on adjacent channels of a
branch are not identical, the FBDIMM on the higher channel is disabled.
•
If Branch 0 cannot support the dual-channel mode of operation for any reason, the
server will run in single-channel mode.
For dual-channel interleave, providing optimum performance, a minimum of two
FBDIMMs must be installed. Populate FBDIMMs of the same size in each channel.
Install these FBDIMMs in DIMM sockets DIMM_A1 and DIMM_B1. For dual-channel
interleave, FBDIMMs must be installed in pairs and populated as follows:
•
DIMM_A1 and DIMM_B1: Populate these two sockets together first.
•
Populate FBDIMMs in channel order, populating all FBDIMMs in each channel.
For example, if four FBDIMMs are to be installed, they need to be in sockets A1,
B1, C1, and D1.
•
The minimum memory population for enabling Branch 1 is four FBDIMMs:
DIMM_A1, DIMM_B1, DIMM_C1 and DIMM_D1.
During the boot process, FBDIMMs that do not meet the population requirements are
disabled.

“Additional
Information and Software” on page viii
Power Supply
A minimum of 550 watts is required. Your power supply must provide a minimum of
3 amps of 5-volt standby current or the server will not boot.
