Installing Memory Modules

This motherboard accommodates two 240-pin DIMM sockets (Dual Inline Memory
Module) for unbuffered DDR2 533/400 memory modules (Double Data Rate
SDRAM), and maximum 2 GB installed memory.
Over its predecessor, DDR-SDRAM, DDR2-SDRAM offers greater bandwidth
and density in a smaller package along with a reduction in power consumption. In
addition, DDR2-SDRAM offers new features and functions that enable a higher
clock rate and data rate operations of 400 MHz, 533 MHz, 667 MHz, and above.
DDR2 transfers 64 bits of data twice every clock cycle.
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.
