Installing Memory Modules - ECS L4S5M2 Manual

Installing Memory Modules

For this mainboard, you must use 168-pin 3.3V unbuffered Dual In-line Mem-
ory Modules (DIMMs).
The memory bus can run at 66 MHz, 100 MHz or 133 MHz. If your processor
operates over a 133 MHz FSB (frontside bus), you can install PC133 or
PC100 memory modules that operate over a 133 or 100 MHz bus. If your
processor operates over a 100 MHz frontside bus, you can install memory
modules that operate over a 133 MHz, 100 MHz or 66 MHz bus. If your proc-
essor operates over a 66 MHz frontside bus, you can only install memory
modules that operate at 66 or 100 MHz.
Installation Procedure
The mainboard accommodates two
memory modules. You must install at
least one module in any of the two
slots. Each module can be installed
with 32 MB to 1 GB of memory; total
memory capacity is 2 GB.
Refer to the following to install the memory modules.
1. Push the latches on each side of the DIMM slot down.
2. Align the memory module with the slot. The DIMM slots are keyed with
notches and the DIMMs are keyed with cutouts so that they can only be
installed correctly.

3. Check that the cutouts on the DIMM module edge connector match the
notches in the DIMM slot:
