Hardware Installation
Warning:
Electrostatic discharge (ESD) can damage your system board, proces-
sor, 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 protec-
tion 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 proce-
dures requiring ESD protection.
System Memory
Warning:
When the DRAM Power LED lit red, it indicates that power is
present on the DDR sockets. Power-off the PC then unplug the
power cord prior to installing any memory modules. Failure to do so
will cause severe damage to the motherboard and components.
The system board supports DDR SDRAM DIMM. Double Data
Rate SDRAM (DDR SDRAM) is a type of SDRAM that doubles the
data rate through reading and writing at both the rising and falling
edge of each clock. This effectively doubles the speed of operation
therefore doubling the speed of data transfer.
