Installing Memory Modules - ECS P4S8A Manual

5. Push down the locking lever and hook it under the latch on the
edge of the socket. This secures the CPU in the socket.
6. All processors should be installed with a combination
heatsink/cooling fan, connect the cable from the fan to the
CPU fan power connector CPUFAN.

Installing Memory Modules

This mainboard accommodates two184-pin 2.5V unbuffered
Double Data Rate (DDR) SDRAM DIMM sockets. When you
install DDR266/DDR333/DDR400 memory modules, the memory
bus can run up to 133/166/200 MHz.
The DDR SDRAM DIMMs can synchronously work with 100
MHz or operates over a 400 MHz (overclock) system bus.
You must install at least one memory module in order to use the
mainboard. Each module can be installed with up to 2GB memory
capacity.
Installation Procedure
To install a module, please follow these steps:
1. Push down the latches on each side of the DIMM socket.
2. Align the memory module with the socket. The DIMM
sockets are keyed with notches and the DIMMs are keyed
with cutouts so that they can only be installed correctly.
3. Check the cutouts on the DIMM module edge connector
matching the notches in the DIMM socket.
4. Install the DIMM module into the socket and press it firmly
down until it is seated correctly. The socket latches are
levered upwards and lock the edges of the DIMM.
5. Install any remaining DIMM modules.
