Installing Memory Modules - Mercury KVM400M-L User Manual

Installing Memory Modules

This mainboard accommodates two 184-pin 2.5V unbuffered
Double Data Rate SDRAM (DDR SDRAM) Dual Inline Memory
Module (DIMM) sockets, and supports up to 2.0 GB of DDR400
SDRAM with KM400A NB or DDR333 SDRAM with KM400
NB.
DDR SDRAM is a type of SDRAM that supports data transfers on
both edges of each clock cycle (the rising and falling edges),
effectively doubling the memory chip's data throughput. DDR
DIMMs can synchronously work with 100MHz, 133MHz or
166MHz, 200MHz(KM400A) memory bus.
DDR SDRAM provides 1.6 GB/s or 2.1 GB/s data transfer rate
depending on whether the bus is 100MHz, 133MHz or 166MHz,
200MHz(KM400A). DDR SDRAM uses additional power and
ground lines and requires 184-pin 2.5V unbuffered DIMM module.
Installation Procedure
These modules can be installed with up to 2 GB system memory.
Following these steps to install the memory module.
1. Push down the latches on both sides of the DIMM
socket.
2. Align the memory module with the socket. There is
a notch on the DIMM socket that you can install the
DIMM module in the correct direction. Match the
