Install Memory - ECS K7AMA User Manual

Install Memory

The mainboard has two 168-pin/184-pin DIMM sockets for
SDRAM/DDR SDRAM (Double Data Rate SDRAM) system
memory modules. You must install at least one memory module in
order to use the mainboard, and you can only use one of the both
SDRAM and DDR SDRAM at the same time .
DDR SDRAM provides 800 MBps or 1 GBps data transfer
depending on whether the bus is 100 MHz or 133 MHz. It doubles
the rate to 1.6 GBps and 2.1 GBps by transferring data on both the
rising and falling edges of the clock. DDR SDRAM uses additional
power and ground lines and requires 184-pin 2.5V unbuffered
DIMM module reather than the 168-pin 3.3V unbuffered DIMMs
used by SDRAM.
For this mainboard, the maximum memory size is 1GB.
The edge connectors on the memory modules have cut outs, which
coincide with spacers in the DIMM sockets so that memory
module can only be installed in the correct orientation.
To install a module, push the retaining latches at either end of the
socket outwards. Position the memory module correctly and insert
it into the DIMM socket. Press the module down into the socket so
that the retaining latches rotate up and secure the module in place
by fitting into notches on the edge of the module.
