Memory modules are
detected, but a memory
configuration or
compatibility error exists.
Ensure that there are no special memory
module/memory connector placement requirements
(see "Memory" in your User’s Guide).
Verify that the memory modules that you are
installing are compatible with your computer (see
"Memory" in your User’s Guide).
Reinstall the memory modules and then restart the

resource and/or hardware

If the problem persists, contact Dell.

failure has occurred.

from the computer for resource conflicts (see
"Resolving Software and Hardware
Incompatibilities" in your User’s Guide).
4If the problem persists, contact Dell.
