Installing Memory Modules - ECS 661GX-M2 V5 Manual

Note: The fan power requirement for proper operation is a maximum current
of 740mA at +12V.

Installing Memory Modules

This motherboard accommodates two 184-pin DIMM sockets (Dual Inline
Memory Module) for unbuffered DDR 400/333/266 (Double Data Rate
SDRAM), and maximum 2 GB installed memory.
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 400/333/
266 MHz memory and provide 3.2 GB/s, 2.7 GB/s, 2.1 GB/s and 1.6 GB/s data
transfer rate.
Memory Module Installation Procedure
These modules can be installed with up to 2 GB system memory. Refer to the
following 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 cutout on the DIMM module with the notch on
the DIMM socket.
3. Install the DIMM module into the socket and press it firmly down
until it is seated correctly. The socket latches are levered upwards and
latch on to the edges of the DIMM.
