ECS Elitegroup 755FX-A939 [20/83] Installing the motherboard

Installing the Motherboard

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 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.

Installing Memory Modules

This motherboard accommodates two 184-pin 2.5V unbuffered DIMM and supports DDR400/

333/266. You must install at least one module in any of the two slots. Each module can be

installed with 256MB to 1GB of memory; the total memory capacity is 2GB.

Do not remove any memory module from its antistatic packaging 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.
