Step 2: Install memory modules

Before installing the processor and heatsink, adhere to the following warning:
When DIMM 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.
The motherboard has 6 dual i n line 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.
DDR2 Introduction
DDR2-SDRAM is considered an evolutionary upgrade over existing DDR memory. It mai n tains the
same core functions, transferring 64 bits of dat a twice every clock cycle f o r an effective transfer rat e twice
that of the f r ont-side bus (FSB) of a computer system, and an eff e ctive bandwidth equal to its speed x 8.
DDR2 introduces some new features which allow it to ramp up to much higher speeds (w ith
correspondingly higher bandwidth) and higher memory densities, all the while using less power. DDR2
memory uses a new form f a ctor, a 240 pin DIMM (Dual Inli n e Memory Module) which is not compatible
with current DDR memory slots. Upcoming chipsets by Intel and other manufacturers will support DDR2
specifically, and are not backwards compatible.
