•
Remove all components from the motherboard, especially the DIMM modules. Make sure
that system power is on and that memory error beeps are activated.
•
Turn on the system with only one DIMM module installed. If the system boots, check for
bad DIMM modules or slots by following the Memory Errors Troubleshooting procedure in
this chapter.
Memory Errors
When a no-memory beep code is issued by the system, check the following:
•
Make sure that the memory modules are compatible with the system and are properly
installed. Refer to
Chapter 3
to the "Tested Memory List" link on the motherboard's product website page to see a list
of supported memory.)
•
Check if different speeds of DIMMs have been installed. It is strongly recommended that
you use the same RAM type and speed for all DIMMs in the system.
•
Make sure that you are using the correct type of non-ECC UDIMM DDR4 modules
recommended by the manufacturer.
•
Check for bad DIMM modules or slots by swapping a single module among all memory
slots and check the results.
Losing the System Setup Configuration
•
Always replace power supplies with the exact same model that came with the system. A
poor quality power supply may cause the system to lose the CMOS setup configuration.
•
The battery on your motherboard may be old. Check to verify that it still supplies
approximately 3VDC. If it does not, replace it with a new one.
•
If the above steps do not fix the setup configuration problem, contact your vendor for repairs.
When the System Becomes Unstable
If the system becomes unstable during or after OS installation, check the following:
•
CPU/BIOS support: Make sure that your CPU is supported and that you have the latest
BIOS installed in your system.
•
Memory support: Make sure that the memory modules are supported by testing the modules
using memtest86 or a similar utility.
