Installation Procedure

Refer to the following to install the memory modules.
1 This motherboard supports unbuffered DDR2 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
the DIMMs in the sequence of DIMM3, DIMM4, DIMM1 and DIMM2.
