Hardware Installation Process

Step 2: Install memory modules
The motherboard has 4 dual inline memory module (DIMM) sockets. The BIOS will automatically
detects memory type and size. To install the memory module, just push it vertically into the DIMM
socket. The DIMM module can only fit in one direction due to the notch. Memory size can vary
between sockets.
Established on the existing SDRAM industry infrastructure, DDR (Double Data Rate) memory is
a high performance and cost-effective solution that allows easy adoption for memory vendors, OEMs
and system integrators.
DDR memory is a sensible evolutionary solution for the PC industry that builds on the existing
SDRAM infrastructure, yet makes awesome advances in solving the system performance bottleneck
by doubling the memory bandwidth. DDR SDRAM will offer a superior solution and migration path from
existing SDRAM designs due to its availability, pricing and overall market support. PC2100 DDR
memory (DDR266) doubles the data rate through reading and writing at both the rising and falling edge
of the clock, achieving data bandwidth 2X greater than PC133 when running with the same DRAM
clock frequency. With peak bandwidth of 2.664GB per second, DDR memory enables system OEMs
to build high performance and low latency DRAM subsystems that are suitable for servers, workstations,
high-end PC's and value desktop SMA systems. With a core voltage of only 2.5 Volts compared to
conventional SDRAM's 3.3 volts, DDR memory is a compelling solution for small form factor desktops
and notebook applications.
DDR Introduction
When RAM_LED is ON, do not install/remove DIMM from socket.
Please note that the DIMM module can only fit in one direction due to the one notches.
Wrong orientation will cause improper installation. Please change the insert orientation.
DDR
1. The DIMM socket has a notch, so the DIMM memory
module can only fit in one direction.
2. Insert the DIMM memory module vertically into the
DIMM socket. Then push it down.
3. Close the plastic clip at both edges of the DIMM sock-
ets to lock the DIMM module.
Reverse the installation steps when you wish to
remove the DIMM module.
