Troubleshooting
No memory modules are
detected. • If two or more memory
modules are installed, remove
the modules (see "Removing
Memory" on page 108), then
reinstall one module (see
"Installing Memory" on
page 106) and restart the
computer. If the computer
starts normally, continue to
install additional memory
modules (one at a time) until
you have identified a faulty
module or reinstalled all
modules without error.
• If available, install working
memory of the same type into
your computer (see "Installing
Memory" on page 106).
• If the problem persists, contact
Dell (see "Contacting Dell" on
page 200).
Memory modules are
detected, but a memory
configuration or
compatibility error has
occurred. • Ensure that no special
requirements for memory
module/connector placement
exist (see "Memory" on
page 104).
• Ensure that the memory you
are using is supported by your
computer (see "Memory" on
page 173).
• If the problem persists, contact
Dell (see "Contacting Dell" on
page 200).
