Chapter 2: Motherboard Installation
Installing Memory Modules
This motherboard accommodates four 184-pin 2.5V DIMM
sockets (Dual Inline Memory Module) for unbuffered DDR400
memory modules (Double Data Rate SDRAM), and maximum
4.0 GB installed memory.
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 266/333/400 MHz memory
bus. DDR SDRAM provides 2.1 GB/s, 2.7 GB/s or 3.2 GB/s data
transfer rate when the bus is 133 MHz, 166 MHz or 200 MHz,
respectively. It supports Dual Channel Technology; when activat-
ing it, the bandwidth of memory bus will be doubled to 6.4 GB/s
and frequency 200 MHz.
3 Push the locking lever down and hook it under the latch
on the edge of socket.
4 Apply thermal grease to the top of the CPU.
5 Install the cooling fan/heatsink unit onto the CPU, and
secure them all onto the socket base.
6 Plug the CPU fan power cable into the CPU fan
connector (CPUFAN) on the motherboard.
