Installing the Motherboard

Installing Memory Modules

This motherboard accommodates four memory modules. It can support six 240-pin

DDR3 1333/1066/800. The total memory capacity is 24 GB.

You must install at least one module in any of the six slots. Each module can be

installed with 4 GB of memory; total memory capacity is 24 GB.

DDR3 800 400 MHz

DDR3 1066 533 MHz

DDR3 1333 667 MHz

Channel A: DDR3_1, DDR3_2

Channel B: DDR3_3, DDR3_4

The six DDR3 memory sockets (DDR3_1, DDR3_2, DDR3_3, DDR3_4, DDR3_5,

DDR3_6) are divided into three channels and each channel has two memory sockets

as following:

Channel C: DDR3_5, DDR3_6

1. To achieve better airflow rates and heat dissipation, we suggest that

you use a high quality fan with 3800 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.

2. DO NOT remove the CPU cap from the socket before installing a

CPU.

3. Return Material Authorization (RMA) requests will be accepted

only if the motherboard comes with the cap on the LGA1366 socket.

Due to Intel CPU spec definition, the system will not boot if only one

DIMM is installed in DDR3_1, DDR3_3, or DDR3_5. Follow the table

above for recommended memory configuration.
