It may be the case that the new 128 RAM module is incompatible with the
other modules that are already installed. Even though it shows up OK in
DocMemory and also when you first boot up the system, this does not mean
that the RAM is actually OK. These tests do not test for compatibility
between Ram modules, or between a Ram module and the motherboard, they just
test that the RAM is present. This happens often when modules from different
manufacturers are used in the same system.
