2.2 System Memory
The 168-pin DIMM (Dual In-
line Memory Module) sockets
support PC SDRAM DIMM,
3.3V. PC SDRAM
(Synchronous Dynamic
Random Access Memory) is a
fast memory interface
technology that includes
using the clock on the chip
to synchronize with the CPU
clock so that the timing of
the memory chips and the
timing of the CPU are synchronized. This saves time during
transmission of data, subsequently increasing system performance.
The system board supports the ECC (Error Checking and
Correction) function. To use this function, you must install DIMM
that supports parity. That is, DIMM that typically has 9 memory
chips per side. This kind of module has 8 standard memory chips
and a parity chip. DIMM with no parity has 8 standard memory
chips only. Refer to chapter 1 (System Memory section) for
detailed specification of the memory supported by your system
board.

2.2.1 Installing the DIM Module
A DIM module simply snaps into a DIMM socket on the system
board. Pin 1 of the DIM module must correspond with Pin 1 of the
socket.
