Installing Memory Modules - ECS K7S5A Manual

7. Connect the CPU Cooling Fan
power cable connector to the
CPUFAN connector.
•
To achieve better airflow rates and heat dissipation, we suggest that
Notes:
you use a high quality fan with 4800 rpm at least.
•
CPU fan and heatsink installation procedures may vary with the type of
CPU fan/heatsink supplied. The form and size of fan/heatsink may also
vary.

Installing Memory Modules

The mainboard has two 168-pin/184-pin DIMM sockets for SDRAM/DDR
(Double Data Rate) SDRAM system memory modules.
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 rather than the 168-pin 3.3V unbuffered
DIMMs used by SDRAM.
Installation Procedure
You must install at least one memory
module in order to use the main-
board.
Note: You cannot use DDR
SDRAM and SDRAM
simultaneously.
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.
