System Boot Failure; Memory Errors; Losing The System's Setup Configuration - Supermicro SuperWorkstation SYS-531A-I User Manual

System Boot Failure

If the system does not display Power-On-Self-Test (POST) 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 Clear CMOS in Chapter 4.
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 3 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 memory type and speed for all DIMM modules 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.

Losing the System's Setup Configuration

1. Make sure that you are using a high-quality power supply. 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.
2. 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.
