A1SAi & A1SRi Series Motherboard User's Manual
2. Use the speaker to determine if any beep codes exist. (Refer to Appendix 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 ECC DDR3 SODIMM (1.5V, 1.35V) 1600/1333
MHz memory recommended by the manufacturer. 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, speeds, or types on the
motherboard. Some 1600MHz memory can be used on A1SRi-2358F, but they
will operate at 1333MHz only.
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.
5. 16GB 1600MHz modules will require BIOS version 1.1a or newer to work. If
you have an older BIOS, please use other modules to boot up the motherboard
in order to update the BIOS or submit an RMA to send back to Supermicro for
the update.
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.
