36 Intel Server Board SDS2 Product Guide
Installing or remo ving jumpers: A jumper is a small plastic encased
conductor that slips over two jumper pins. Some jumpers have a small tab on
top that you can grip with your fingertips or with a pair of fine needle nosed
pliers. If your jumpers do not have such a tab, take care when using needle
nosed pliers to remove or install a jumper; grip the narrow sides of the
jumper with the pliers, never the wide sides. Gripping the wide sides can
damage the contacts inside the jumper, causing intermittent problems with
the function controlled by that jumper. Take care to grip with, but not
squeeze, the pliers or other tool you use to remove a jumper, or you may
bend or break the stake pins on the board.
Memory
The SDS2 Server Board contains six 168-pin DIMMs. Memory is partitioned as three banks.
DIMMs must be populated in identical pairs.
The SDS2 server board supports up to six 3.3-V, registered ECC SDRAM DIMMs that are
compliant with the JEDEC PC133 specification. A wide range of DIMM sizes are supported,
including 64 MB, 128 MB, 256 MB, 512 MB, and 1 GB DIMMs. The minimum supported memory
configuration is 128 MB, using two identical 64 MB DIMMs. The maximum conf igurable memory
size is 6 GB using six 1 GB DIMMs.
The SDRAM interface runs at the same frequency as the processor bus. The memory controller
supports 2-way interleaved SDRAM, memory scrubbing, single bit error correction and multiple bit
error detection. Memory can be implemented with either single -sided (one row) or double -sided
(two row) DIMMs.

NOTE
Use DIMMs that have been tested for compatibility with the server board.
