Identifying The Parts Of The System Board - IBM Aptiva Handbook

The system board, sometimes called the planar or motherboard, is the main circuit board in the system unit. It supports a
variety of devices and provides other basic computer functions that are preinstalled or that you can install later. The system
board shown on the previous page has the following parts:
Memory module sockets (for DIMMs). Your system
1
board has two 168-pin sockets labeled DIMM Bank 0 and
DIMM Bank 1 for Dual lnline Memory Modules
(DIMMs).The DIMM sockets support 3.3V single-or
double-sided Synchronous DRAM (SDRAM). The
maximum system memory is 256 MB.
2
