System Boot Failure; Memory Errors - Supermicro SuperServer 510P-WT/WTR User Manual

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).
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 are properly
installed. See Chapter 2 for installation instructions. (For memory compatibility, refer to the
"Tested Memory List" link on the motherboard's product page to see a list of supported
memory.)
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 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.
