Installing Memory Modules
661FX-M Deluxe accommodates two 184-pin 2.5V unbuffered Double Data
Rate (DDR) SDRAM (Synchronous Dynamic Random Access Memory)
memory modules. 661FX-M Deluxe can support DDR400/DDR333/DDR266
memory modules and allow to maximum memory size 2 GB.

This motherboard has a Socket 478 processor socket. When choosing a
processor, consider the performance requirements of the system. Perfor-
mance is based on the processor design, the clock speed and system bus
frequency of the processor, and the quantity of internal cache memory and
external cache memory.
1. Install your CPU. Pull up the lever away
from the socket and lift up to 90-degree
angle.
2. Locate the CPU cut edge (the corner with the
pin hold noticeably missing). Align and insert
the CPU correctly.
3. Press the lever down and apply thermal
grease on top of the CPU.
4. Put the CPU Fan down on the retention
module and snap the four retention legs of
the cooling fan into place.
5. Flip the levers over to lock the heat sink in
place and connect the CPU cooling Fan
power cable to the CPUFAN connector. This
completes the installation.
To achieve better airflow rates and heat dissipation, we suggest
that 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.
The motherboard accommodates two memory modules. You must install at
least one module in any of the two slots. Each module can be installed with
128 MB to 1 GB of memory; total memory capacity is 2 GB.
Do not remove any memory module from its antistatic packag-
ing until you are ready to install it on the motherboard. Handle
the modules only by their edges. Do not touch the components
or metal parts. Always wear a grounding strap when you handle
the modules.
CPU Installation Procedure
The following illustration shows CPU installation components.
Memory module No. of DIMMs Memory Bus
DDR266 2DIMMS 133MHz
DDR333 2DIMMS 166MHz
DDR400 2DIMMS 200MHz
Installation Procedure
Refer to the following to install the memory modules.
1 . This motherboard supports unbuffered DDR SDRAM only.
2. Push the latches on each side of the DIMM slot down.
3. 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.
4 . Check that the cutouts on the DIMM module edge connector
match the notches in the DIMM slot.
5 . Install the DIMM module into the slot and press it firmly down
