Installing Memory Modules
This motherboard accommodates 184-pin 2.5V unbuffered Double Data Rate
(DDR) SDRAM memory modules. The memory chips must be standard or
registered SDRAM (Synchronous Dynamic Random Access Memory). The
memory bus runs at 166 MHz.
Note:
SDRAM provides 800 MBps or 1 GBps data transfer depending on
whether the bus is 100MHz or 133MHz. Double Data Rate SDRAM
(DDR SDRAM) doubles the rate to 1.6 GBps and 2.1 GBps. DDR
SDRAM uses additional power and ground lines and requires 184-pin
DIMM modules rather than the 168-pin DIMMs used by SDRAM.
The motherboard accommodates two memory modules. You must install at
least one module in any of the two slots. Each module can be installed with 32
MB to 1 GB of memory; total 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.
Refer to the following to install the memory modules.
1. This motherboard supports unbuffered DDR SDRAM only. Do not attempt
to insert any other type of DDR SDRAM into the slots.
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.
