Probable cause
Option ROM for a device could not run
because of memory constraints.
RTC power (CMOS battery) is lost
● Invalid time or date in
configuration memory.
● RTC battery might need
replacement.
● CMOS jumper might not be
properly installed.
Memory configuration is incorrect.
RAM failure.
Memory modules do not match.
Defective memory module.
Improper module load.
Insufficient memory module cooling.
Memory configured incorrectly.
DIMMs are installed that do not fulfill
system requirements.
Recommended action
Run the Computer Setup (F10) Utility to disable
unneeded option ROMs, and to enable ACP1/USB
Buffers at Top of Memory.
1. Run Computer Setup (F10) Utility and set
default settings.
2. Replace the CMOS battery.
3. Replace the system board.
1. Set the date and time from the Control Panel
or in the Computer Setup (F10) Utility
(depending on the operating system).
2. If the problem persists, replace the RTC
battery.
1. Run the Computer Setup (F10) Utility or the
Windows utilities.
2. Verify that the memory modules are installed
properly.
3. If third-party memory has been added, test
the memory configuration using HP memory.
4. Verify the memory module type.
1. Run the Computer Setup (F10) Utility or the
Windows utilities.
2. Be sure that memory modules are installed
correctly.
3. Verify the memory module type.
4. Remove and replace memory modules one at
a time to isolate faulty modules.
5. Replace faulty memory modules.
6. If the error persists after replacing memory
modules, replace the system board.
Replace the memory modules with matched sets.
Replace the memory module.
Reseat the memory module correctly.
Verify that a memory module cooling fan is installed
and operating.
Reconfigure the memory modules in the proper
slots.
1. Verify that the memory module type matches
computer requirements.
2. Insert the DIMM in the proper memory socket.
3. Replace the DIMM if the problem persists.
