2. Install a PC buzzer via JD1 to determine if any beep codes exist. (Refer to Ap-
pendix A for details on beep codes.)
3. Remove all memory modules and turn on the system. (If the alarm is on, check
the specifications of memory modules, reset the memory or try a different one.)

Memory Errors

1. Make sure that the DIMM modules are properly installed and fully seated in
the slots.
2. You should be using either DDR4 ECC RDIMM or ECC/Non-ECC UDIMM up to
2133MHz memory recommended by Supermicro. Also, it is required that you use
the memory modules of the same type and speed for all DIMMs in the system.
Do not use memory modules of different sizes, different speeds, nor different
types on the same motherboard.
3. Check for bad DIMM modules or slots by swapping modules between slots to
see if you can locate the faulty ones.
4. Check the switch of 115V/230V power supply.
Losing the System's Setup Configuration
1. Please be sure to use a high quality power supply. A poor quality power supply
may cause the system to lose CMOS setup information. Refer to Section 1-6
for details on recommended power supplies.
2. The battery on your motherboard may be old. Check to verify that it still sup-
plies ~3VDC. If it does not, replace it with a new one.
3. If the above steps do not fix the Setup Configuration problem, contact your
vendor for repairs.
