Probable cause
Memory modules do not match each
other.
Single-bit ECC error.
Processor has failed to initialize.
A memory module in memory socket
identified in the error message is
missing critical SPD information or is
incompatible with the chipset.
DIMMs not installed correctly (not
paired correctly).
There are one or more mismatched
pairs of DIMMs between channel A and
channel B. Some memory has been
disabled. Install matching pairs or
remove the mismatched DIMMs from
channel B.
The amount of memory installed
exceeds that supported by the
hardware.
ECC modules not supported on this
platform.
Keyboard failure.
I/O board keyboard controller.
Keyboard failure.
Recommended action
3. Verify proper memory module type.
4. Remove and replace memory modules one at a
time to isolate faulty module.
5. Replace the faulty memory modules.
6. If error persists after replacing memory modules,
replace the system board.
Replace memory modules with matched sets.
1. Verify proper memory module type.
2. Insert the DIMM in another memory socket.
3. Replace memory module if problem persists.
1. Reseat the processor in its socket.
2. If the processor does not respond, replace it.
1. Verify proper memory module type.
2. Insert the DIMM in another memory socket.
3. Replace memory with a module conforming to the
SPD standard.
See the illustration on the side access panel for the
correct memory configurations and reseat the DIMMs
accordingly.
