Control panel message Description Recommended action
3. If the memory conguration was
recently changed, unplug the power
cord, restore the original memory
conguration, and reboot the
computer.
4. If the error persists, replace the
system board.
00E-Inventory Error during MEBx
Execution
BIOS information passed to the MEBx
resulted in a failure.
1. Reboot the computer.
2. If the error persists, update to the
latest BIOS version.
3. If the error still persists, replace the
system board.
00F-Interface Error during MEBx Execution MEBx operation experienced a hardware
error during communication with the ME.
1. Reboot the computer.
2. If the error persists, update to the
latest BIOS version.
3. If the error still persists, replace the
system board.
100-Front Audio Not Connected Front audio cable has been detached or
unseated from system board.
Reconnect or replace front audio cable.
2E1-MemorySize Error Memory amount has changed since the
last boot (memory added or removed).
The system memory size is dierent from
the last startup. The most common reason
is the removal of memory from the system
board. Press the f1 key to save the
memory changes.
2E2-Memory Error Memory module conguration failed
during boot up.
1. Be sure that memory modules are
correctly installed.
2. Verify proper memory module type.
3. Remove and replace the identied
faulty memory modules.
4. If the error persists after replacing
memory modules, replace the system
board.
2E3-Incompatible Memory Module in
Memory Socket(s) X, X, ...
A memory module in memory socket
identied in the error message is missing
critical SPD information, or is incompatible
with the chipset.
1. Verify proper memory module type.
2. Try another memory socket.
3. Replace with a supported module.
2E4-DIMM Conguration Warning Populated DIMM Conguration is not
optimized.
Rearrange the DIMMs so that each channel
has the same amount of memory.
2E5-ECC Memory Module Detected on
Unsupported Platform
Recently added memory modules support
ECC memory error correction.
1. If additional memory was recently
added, remove it to see if the
problem remains.
2. Check product documentation for
memory support information.
2E6–Memory Not Congured Correctly for
Proper MEBx Execution
DIMM1 is not installed. Make sure there is a memory module in
the DIMM1 socket and that it is properly
seated.
