Notes on installing memory modules
Identifying memory modules
Make sure to install a pair of DIMMs, each having the same capacity. Check that the number beginning
with "CA" (e.g., CA05946-E101) printed on the label is same on the two DIMMs. Be sure to use a pair
of modules with the same number.
If the DIMMs have identification labels, be sure to install a pair of DIMMs with the same capacity with
the label placed on the same location.
