seated properly.
Replace module with the correct, industry-standard device
for the workstation.
On some models, ECC and nonECC memory modules
cannot be mixed.
Out of memory error.
Memory configuration might
not be set up correctly.
Use the Device Manager to verify memory configuration.
You have run out of memory to
run the application.
Review the application documentation to determine the
memory requirements.
Memory count during POST is
wrong.
The memory modules might
not be installed correctly.
Verify that the memory modules have been installed
correctly and that proper modules are used.
Insufficient memory error during
operation.
Too many Terminate and Stay
Resident (TSR) programs are
installed.
