2.6 System Installation___________________ 2.6.1 Installing Memory The SMB-2501 contains three sockets for 184-pin dual inline memory modules (DIMMs). All these sockets accept un-buffered DDR266 SDRAMs. The un-buffered DDR266 DIMMs are available in 128, 256, 512 and 1024 MB. The sockets can be filled in any combination with DDR DIMMs of any size, allowing the SMB-2501 up to 3 GB of memory. 2.6.
DDR DIMM (184-pin) Press the socket retaining latches back out of the way RS-100-SF User’s Manual 23
Orient the DDR DIMM so that the edge connector sections correctly match the socket sections. Holding the DIMM to the socket, place it in the socket so that the edge connectors insert slightly in the socket. Make sure they match. Press the DDR DIMM into the socket so that it seats firmly in place and the retaining latches rotate upwards and seat them selves in the notches on the side of the DDR DIMM. Repeat this operation for the rest of DIMMs you will install.
2.6.3 Cache Memory Since the second level (L2) cache has been embedded into the Intel® Pentium® 4 / Celeron processor, you do not have to take care of either SRAM chips or SRAM modules. The built-in second level cache in the Pentium® 4/ Celeron processor yields much higher performance than the external cache memories. The cache size in the Intel® Pentium® 4 processor is 512KB, depending on the type of CPU. The cache size in the Intel® Celeron processor is 128KB.
2.6.4 CPU Installation The RS-100-SF provides an mPGA 478 socket for an Intel® Pentium® 4/ Celeron Processor. The CPU on the board must have a fan or heat sink attached, to prevent overheating. Warning: Without a fan or heat sink, the CPU will overheat and cause damage to both the CPU and the motherboard. To install a CPU, first turn off your system. Locate the processor socket 478.
Make sure the socket 478 lever is at the upright position. To raise the lever, pull it out to the side a little and raise it as far as it will go. Place the CPU in the empty socket. Follow the instructions that came with the CPU. If you have no instructions, complete the following procedure. Carefully align the CPU so it is parallel to the socket and the notches on the corners of the CPU correspond with the notches on the inside of the socket. Gently slide the CPU in. It should insert easily.
Press the lever down. The plate will slide forward. You will feel some resistance as the pressure starts to secure the CPU in the socket. This is normal and will not damage the CPU. When the CPU is installed, the lever should snap into place at the side of the socket. Note: To remove a CPU, pull the lever out to the side a little and raise it as far as it will go. Lift out the CPU. Paint the heat-spread glue on the CPU evenly. (It is recommended, but some CPU cooler fan comes with a thermal pad.
Place CPU cooler fan to sit on the top of the installed CPU, then fasten the cooler fan on the motherboard with screw. Please connect the fan power cable to JP35, the 3-pin fan power connector, on the board.
