A1, A2, A3, and A4. Banks B, C, and D each contain 4 DIMM sockets and are named in
the same fashion. There are silk screens on the module next to each DIMM socket to label
its bank number. For the best thermal results, populate the banks from A to D. For
example, populate bank A and then bank B. For best performance results, populate
adjacent banks. For example, populate bank A and then bank C.
Figure 2-2 shows a detailed view of the memory module slots.

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.
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 systems
