Memory; Installing Dimms - Intel SCB2 - Server Board Motherboard Product Manual

Installing or removing 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 server board supports from 128 MB up to 6 GB of registered memory in six DIMM slots.
NOTE
Only PC133-compliant SDRAM is supported by the server board.
A 1U chassis requires low-profile (LP) 1.2-inch (30 mm) tall DIMMs.
DIMMs must be populated in pairs and in the following order:
1a and 1b, then 2a and 2b, then 3a and 3b.
Installed DIMMs must be the same speed and must all be registered.
