3. Remove all memory modules and turn on the system (if the alarm is on, check the

specs of memory modules, reset the memory or try a different one).

System Boot Failure

If the system does not display POST (Power-On-Self-Test) or does not respond after the

power is turned on, check the following:

1. Check for any error beep from the motherboard speaker.

• If there is no error beep, try to turn on the system without DIMM modules installed. If there

is still no error beep, replace the motherboard.

• If there are error beeps, clear the CMOS settings by unplugging the power cord and

contacting both pads on the CMOS Clear Jumper (JBT1). Refer to Chapter 2.

2. Remove all components from the motherboard, especially the DIMM modules. Make

sure that system power is on and that memory error beeps are activated.

3. 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:

1. Make sure that the memory modules are compatible with the system and that the

DIMMs are properly and fully installed. (For memory compatibility, refer to the memory

compatibility chart posted on our website at http://www.supermicro.com.)

2. 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.

3. Make sure that you are using the correct type of UDIMM ECC DDR4 modules

recommended by the manufacturer.

4. Check for bad DIMM modules or slots by swapping a single module among all memory

slots and check the results.
