Problem Description
Memory modules are detected, but a
memory failure has occurred.
Suggested Resolution
Reseat the memory modules to ensure
1
that your computer is successfully
communicating with the memory.
Restart the computer.
2
If the problem still exists, remove all
3
the memory modules and install
one memory module in
connector DIMM_1.
Restart the computer.
4
The following message appears:
Alert! Operating in Debug
Mode. Please Populate
Memory in Pairs for
Normal Operation.
Press <F1> to boot to the
5
operating system.
Run the Dell Diagnostics
6
(see page 26).
If the memory module passes, shut
7
down the computer, remove the
memory module, and then repeat the
process with the remaining memory
modules until a memory error occurs
during start-up or diagnostic testing.
If the first memory module tested is
defective, repeat the process with the
remaining modules to ensure that the
remaining modules are not defective.
When the defective memory module

is identified, contact Dell for
a replacement.
NOTE:
If necessary, the computer can
operate in debug mode until new memory
modules are installed.
