Memory modules are detected, but a
memory configuration or compatibility
error exists.
• Ensure that no special memory
module/memory connector placement

you are installing are compatible with
your computer (see page 57).
• If the problem persists, contact Dell
(see page 105).

occurred.
1
Determine if a conflict exists by
removing a card (not a graphics card)
and restarting the computer (see
page 60).
2
If the problem persists, reinstall the
card that you removed, remove a
different card, and then restart the
computer.
3
Repeat this process for each card. If
the computer starts normally,
troubleshoot the last card removed
from the computer for resource
conflicts (see "Resolving Software and
Hardware Incompatibilities" on
page 46).
4
If the problem persists, contact Dell
(see page 105).
