Intel® Server Board S5500WB TPS Functional Architecture The BIOS will always enable high-memory reclaim if it discovers installed physical memory equal to or greater than 4 GB. For the operating system, the reclaimed memory is recoverable only when it supports and enables the PAE feature in the processor. Most operating systems support this feature. For details, see the relevant operating system manuals. 3.4.6 Memory Population Rules You should populate the memory slots of DDR3 channels furthest from the processor first. Therefore, if A1 is empty, you cannot populate/use A2. Figure 16. Memory Channel Population 3.4.7 Installing and Removing Memory The silkscreen on the board next to CPU1 displays: DIMM_A2, DIMM_A1, DIMM_B1, DIMM_C1, and next to CPU2 display: DIMM_D2, DIMM_D1, DIMM_E1, DIMM_F1 starting from the inside of the board. DIMM_A1 is the blue socket closest to the CPU 1 socket. For memory channel A, the server board requires DDR3 DIMMs within a channel to be populated starting with the DIMM farthest from the processor. The DIMM farthest from the processor per channel is blue on the board. 3.4.7.1 Installing DIMMs To install DIMMs, follow these steps: 1. Turn off the server. 2. Disconnect the AC power cord from the server. 3. Remove the server's cover and locate the DIMM sockets (see ― Installing Memory‖). Revision 1.9 23 Intel order number E53971-008

The BIOS will always enable high-memory reclaim if it discovers installed physical memory
equal to or greater than 4 GB. For the operating system, the reclaimed memory is recoverable
only when it supports and enables the PAE feature in the processor. Most operating systems
support this feature. For details, see the relevant operating system manuals.
3.4.6
Memory Population Rules
You should populate the memory slots of DDR3 channels furthest from the processor first.
Therefore, if A1 is empty, you cannot populate/use A2.

Installing and Removing Memory
The silkscreen on the board next to CPU1 displays: DIMM_A2, DIMM_A1, DIMM_B1,
DIMM_C1, and next to CPU2 display: DIMM_D2, DIMM_D1, DIMM_E1, DIMM_F1 starting from
the inside of the board. DIMM_A1 is the
blue
socket closest to the CPU 1 socket. For memory
channel A, the server board requires DDR3 DIMMs within a channel to be populated starting
with the DIMM farthest from the processor. The DIMM farthest from the processor per channel
is blue on the board.
3.4.7.1
Installing DIMMs
To install DIMMs, follow these steps:
1. Turn off the server.
2.
Disconnect the AC power cord from the server.
3.
Remove the server’s cover and locate the DIMM sockets (see
―
Installing Memory
‖
).
