Inserting RAM modules
There are various types of random access memory. The latest motherboards
are equipped with DDR2 or DDR memory. Some are even equipped
with RAMBus memory. The oldest ones actually have SDRAM
connectors, or even EDO RAM connectors.
It is generally impossible to insert non-supported RAM into the
motherboard as each memory type has one or several notches that prevent it from
being inserted into the wrong slot type.
DDR, SDRAM or RAMBus
DDR, SDRAM or RAMBus memory modules can be inserted in memory slots one at a time. It is not recommended
to insert memory modules of different types (and brands), for the following reasons:
- they may be incompatible;
- the computer is forced to run at the speed of the slowest memory module.
To insert DDR, RAMBus or SDRAM,memory modules just pull open the clips located at each end of the slot, place the
memory module straight down into the slot, making sure it is in the correct position (one or more notches between
the pins prevent the module from being inserted the wrong way around).
Press down firmly without forcing. The two clips at each end should close by themselves.
DRAM / EDO
DRAM or EDO RAM must be inserted in pairs, i.e. for 32MB you should install 2 16MB modules.
Inserting EDO memory is quite tricky. Place it into the slot at a 45° angle, then click it in place
