Installing the Motherboard

Installation Procedure

Refer to the following to install the memory modules.

1 This motherboard supports unbuffered DDR3 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 until it

seats correctly. The slot latches are levered upwards and latch on to

the edges of the DIMM.

6 Install any remaining DIMM modules.

For best performance and compatibility, we recommend that users install

DIMMs in the sequence of DIMM3, DIMM4, DIMM1 and DIMM2.
