Installing the Motherboard
Installation Procedure
Refer to the following to install the memory modules.
1 This motherboard supports unbuffered DDR and DDR2 SDRAM .
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 accomodates four memory modules. It can support two 184-pin 2.5V
unbuffered DIMM, DDR 400/333/266 or two 240-pin 1.8V DDR2 533/400. The total
memory support capacity is 2GB.
DDR SDRAM memory module table
You must install at least one module in any of the four slots. Each module can be installed
with 256 MB to 1 GB of memory; total support memory capacity is 2 GB.
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.
Users please note that DDR & DDR2 can’t both be applied at the same time on
