26 Boardset Description
DIMM Installation Sequence
A single carrier will support DIMM population in various configurations (empty sockets included).
However, when fewer than 16 DIMMs are installed on a memory module, the preferred population
order is to start from the lowest J number and populate sequentially to the highest. This
recommendation helps maintain optimal signal integrity and thermal performance.
✏NOTE
Maximum capacity is limited to 16 GB with one memory module installed.
This increases to 32 GB with two modules.
Some OSs and application programs use base memory while others use both conventional and
extended memory. Examples:
• Base memory: MS-DOS†, OS/2, Windows NT†, and UNIX†
• Conventional and extended memory: OS/2, Windows NT, and UNIX
MS-DOS does not use extended memory; however, some MS-DOS utility programs like RAM
disks, disk caches, print spoolers, and windowing environments use extended memory for better
performance.
BIOS automatically detects, sizes, and initializes the memory array, depending on the type, size,
and speed of the installed DIMMs, and reports memory size and allocation to the system via
configuration registers.
✏NOTE
DIMM sizes and compatibility: Use DIMMs that have been tested for
compatibility. Contact your sales representative or dealer for a list of
approved DIMMs.
