Memory errors might stop system operations, show error messages on
the screen, or hang the system. The computer detects memory parity errors but
does not correct them.
Use the following procedure to isolate memory problems.
Memory Error Notes
- Ignore any references to parity errors.
- Remove any installed PCMCIA memory cards.
- Make sure that any memory options are fully installed
into their connectors. A loose connection can cause an error.
- Run the diagnostics. See 'How to Run Diagnostics'
- If memory problems occur intermittently,
use the loop option to repeat the test.
- FRUs should not be replaced because of a single, un-reproducible
failure. Single failures can occur from a variety of reasons
that have nothing to do with a hardware defect such as
electrostatic discharge or software errors.
FRU replacement should only be considered when
a recurring problems exits.
