rotated in the proper position. The tops should be turned in the opposite direction of the arrows
on top. Set the heatsink on the processor such that the four pins engage in the holes surrounding
the socket. Then push down each of the four pins until they click or latch into place. This can
take more force than you might think is prudent, so be sure to visually inspect the installation to
ensure that all four pins have fully engaged and are locked. Some heatsinks use one or more
retainer clips (see
Figure 19.12
). With this type you must be careful when attaching the clip to
the socket; you don't want it to scrape against the motherboard, which can damage circuit traces
or components. You also need to keep the heatsink steady on the chip while attaching the clips,
so do not move, tilt, or slide the heatsink while you attach it.

Connect the fan. Plug the fan power connector into the CPU fan connector supplied on the
motherboard (refer to
Figure 19.10
), which should be near the processor socket. Optionally,
some heatsinks use a peripheral power connector for fan power. Route the fan wires such that
they won't interfere with the fan or any other components.

Configure the motherboard jumpers (if necessary). Older motherboards used jumpers to
configure processor and bus speeds, while some newer motherboards use jumpers to configure
integrated video. Refer to the motherboard manufacturer's manual to set the jumpers, if any, to
match the CPU you are going to install. In modern systems, the processor configuration is done
via the motherboard BIOS Setup.
Installing Memory Modules
To function, the motherboard must have memory installed on it. Modern motherboards use DDR2 or
DDR3 DIMMs. (DDR4 memory will be available in systems starting in the 2013-2014 timeframe.)
Usually, you install modules in the lowest-numbered sockets or banks first. Note that multichannel
boards perform best if modules are installed in matched multiples. Consult the motherboard
documentation for more information on which sockets to use first and in what order and how to install
the specific modules the board uses.
