The Symptom-to-FRU index lists error symptoms and possible causes. The most
likely cause is listed first. Always begin with “Chapter 1. General checkout,” on page
1. This index can also be used to help you decide which FRUs to have available when
servicing a computer. If you are unable to correct the problem using this index, go to
“Undetermined problems” on page 81.
SIMM/DIMM/RIMM memory errors
SIMM/DIMM/RIMM error messages issued by the IBM PC Enhanced Diagnostics.
Notes:
• If you have both an error message and an incorrect audio response, diagnose the error message first.
• If you cannot run the diagnostic tests or you get a diagnostic error code when running a test, but did receive a
POST error message, diagnose the POST error message first.
• If you did not receive any error message, look for a description of your error symptoms in the first part of this
index.
• Check all power supply voltages before you replace the system board (see “20-pin power supply connection” on
page 34).
• Check the hard disk drive jumper settings before you replace a hard disk drive (see “Hard disk drive jumper
settings” on page 31).
Important:
Some errors are indicated with a series of beep codes (see “Beep symptoms” on page 64).
Type 6866 computers default to come up quiet (no beep and no memory count and checkpoint code display) when no
errors are detected by POST. To enable beep and memory count and checkpoint code display when a successful POST
occurs, do the following:
1. Select Start Options in the Configuration/Setup Utility program (see “Setup Utility program” on page 5).
2. Set Power-On Self-Test to Enhanced.
The processor is a separate FRU from the system board; the processor is not included with the system board FRU.
Error FRU/Action
2xx-1y
A memory error was detected in SIMM socket Y.
Replace the SIMM in the socket identified by the last digit
of the error code.
Re-run the test.
If the same error code occurs again, replace the system
board.
