Memory errors can 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.
NOTE:
- Except Model 755CX,
installing a non-parity memory card causes memory errors.
Before you go to the next procedure, check whether or not
the memory card use parity or non-parity.
If the non-parity memory card is installed,
disable the parity check on the Easy-Setup configuration screen.
- Make sure that the memory card is fully installed
into the connector.
A loose connection can cause an error.
- Power-off the computer and
remove the IC DRAM card, or DIMM card
from its slot (if installed).
- Press and hold the F1 key, then power-on the computer.
Hold the F1 key down until the Easy-Setup screen appears.
- Select Test and press enter.
- Select Memory and press enter to
run the memory test on base memory. If an error appears, replace the
memory card.
- Power-off the computer and reinstall the IC DRAM card or the DIMM
card, then power-on the computer.
Verify the memory size, then test the memory.
If an error appears, replace the IC DRAM card or the DIMM card.
If memory problems occur intermittently,
use the loop option to repeat the test.
When the test detects an error,
an error log is printed on the
printer connected to the parallel port.
See 'Error Log' for more information.
