Problem Description
System board failure has
occurred.
Memory modules are detected,
but a memory configuration or
compatibility error exists.
Routine system activity
preceding video initialization.
Suggested Resolution
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
8
memory module is
identified, contact Dell
for a replacement (see
"Contacting Dell" on
page 287).
Contact Dell for technical
assistance (see "Contacting
Dell" on page 287).
• Ensure that no special
memory module/memory
connector placement
requirements exist (see
"Memory" on page 172).
• Verify that the memory
modules that you are
installing are compatible
with your computer (see
"Memory" on page 172).
• Reinstall the memory
modules and restart the
computer.
• If the problem persists,
contact Dell (see
"Contacting Dell" on
page 287).
Watch your monitor for on-
screen messages.
