2.2 System Memory
The system board is
equipped with two 168-
pin DIMM (Dual In-line
Memory Module) sockets
that support unbuffered
PC-100 SDRAM DIMM.
PC SDRAM (Synchro-
nous Dynamic Random
Access Memory) is a
fast memory interface
technology that uses 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 onboard VGA shares 1MB of the system memory. This is fixed
regardless of the size of the system memory.
Aside from the 1MB shared memory, it also uses Dynamic Video
Memory Technology (DVMT). DVMT freely changes in size because
graphics memory is allocated from the system memory according to
current needs.
Refer to chapter 1 for the type of memory supported by the
system board.
Warning:
Electrostatic discharge (ESD) can damage your system board,
processor, disk drives, add-in boards, and other components. Perform
the upgrade instruction procedures described at an ESD workstation
only. If such a station is not available, you can provide some ESD
protection by wearing an antistatic wrist strap and attaching it to a
metal part of the system chassis. If a wrist strap is unavailable,
establish and maintain contact with the system chassis throughout
any procedures requiring ESD protection.
