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, 133 MHz, 166
MHz or 200 MHz memory bus.
DDR SDRAM provides 1.6 GB/s, 2.1 GB/s, 2.7 GB/s or 3.2 GB/s
data transfer rate when the bus is 100 MHz, 133 MHz, 166 MHz or
200 MHz, respectively.
Memory Module Installation Procedure
These modules can be installed with up to 2 GB system memory.
Refer to the following to install the memory module.
1. Push down the latches on both sides of the DIMM
socket.
2. Align the memory module with the socket. There is
a notch on the DIMM socket that you can install
the DIMM module in the correct direction. Match
the cutout on the DIMM module with the notch on
the DIMM socket.
3. Install the DIMM module into the socket and press
it firmly down until it is seated correctly. The
socket latches are levered upwards and latch on to
the edges of the DIMM.
4. Install any remaining DIMM modules.
