should be balanced so that the largest amount of memory is spread between the two channels.
If one channel will have more memory than the other, the larger amount should be assigned to
Channel A. For example, if you are populating the sockets with one 2-GB DIMM, and three 1-GB
DIMMs, Channel A should be populated with the 2-GB DIMM and one 1-GB DIMM, and Channel
B should be populated with the other two 1-GB DIMMs. With this configuration, 4-GB will run as
dual channel and 1-GB will run as single channel.
●
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

Installing DIMMs

CAUTION:
Regardless of the power-on state, voltage is always supplied to the memory modules as long as the
computer is plugged into an active AC outlet. Adding or removing memory modules while voltage is
present may cause irreparable damage to the memory modules or system board.
The memory module sockets have gold-plated metal contacts. When upgrading the memory, it is
important to use memory modules with gold-plated metal contacts to prevent corrosion and/or
oxidation resulting from having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before
beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
