Installing Memory Modules
This mainboard accommodates two 184-pin 2.5V unbuffered Double Data
Rate SDRAM (DDR SDRAM) Dual Inline Memory Module (DIMM) sockets,
and supports up to 1.0 GB of 266 MHz DDR SDRAM.
DDR SDRAM is a type of SDRAM that supports data transfers on both edges
of each clock cycle (the rising and falling edges), effectively doubling the
memory chip’s data throughput. DDR DIMMs can synchronously work with
100 MHz or 133 MHz memory bus.
DDR SDRAM provides 1.6 GB/s or 2.1 GB/s data transfer rate depending on
whether the bus is 100 MHz or 133 MHz. DDR SDRAM uses additional power
and ground lines and requires 184-pin 2.5V unbuffered DIMM module.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the mainboard. 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.
Installation Procedure
Refer to the following to install the memory modules.
1. This mainboard 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 in-
stalled 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.
