Each slot is identified by another notation. Sockets A1 through A4 are identified as J1 through J4 respectively. Sockets B1 through B4 are identified as J5 through J8. Sockets C1 through C4 are identified as J9 through J12. Sockets D1 through D4 are identified as J13 through J16.

✏NOTE

Based on the chipset, addressable memory can be extended to 16 GB. However, some server systems are not thermally configured to support all 16 GB. Consult the documentation accompanying your server system to determine the maximum memory configuration of your server system.

Some operating systems and application programs use base memory while others use both conventional and extended memory. Examples are

∙Base memory: Microsoft MS-DOS†, IBM OS/2†, Microsoft Windows NT†, and various UNIX†

∙Conventional and extended memory: IBM OS/2, Microsoft Windows NT, and various 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.

The 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 with the baseboard. For a list of approved DIMMs, see the SKA4 Memory Qualification List. The document can be found on
