Supermicro C7B250-CB-MK Motherboard User’s Manual

5. 

The battery on your motherboard may be old. Check to make sure 
that it still supplies ~3VDC. If it does not, replace it with a new 
one.

No Video

1. 

If the power is on, but you have no video in this case, you will 

need to remove all the add-on cards and cables first.

2. 

Use the speaker 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 unbuffered Non-ECC DDR4 (up to 2400MHz) 
memory recommended by the manufacturer. Also, it is recom-
mended 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 and different types on the same 
motherboard.

3. 

Check for bad DIMM modules or slots by swapping modules be-
tween slots to see if you can locate the faulty ones.

4. 

Check the switch of 115V/230V power supply.

When the System is Losing the 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 informa-
tion. Refer to Section 1-5 for details on recommended power sup-
plies.

2. 

The battery on your motherboard may be old. Check to verify that 
it still supplies ~3VDC. If it does not, replace it with a new one.
