Installing Memory Modules
This motherboard accommodates two 184-pin 2.5V unbuffered Double Data
Rate (DDR) SDRAM memory modules. Double Data Rate (DDR) SDRAM
doubles the rate to 1.6 GBps and 2.1 GBps. The memory chips must be stan-
dard SDRAM (Synchronous Dynamic Random Access Memory). The memory
bus can run up to 133 MHz.
When you installed DDR266 memory modules, the memory bus can run up to
133 MHz. If you have DDR200, this can only run up to 100 MHz.
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
128 MB to 1 GB of memory; 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.
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.
