2. 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.
3. If the above steps do not fi x the Setup Confi guration problem, contact your
vendor for repairs.
NOTE
If you are a system integrator, VAR or OEM, a POST diagnostics
card is recommended. For I/O port 80h codes, refer to App. B.
Memory Errors
1. Make sure that the DIMM modules are properly and fully installed.
2. Check if different speeds of DIMMs have been installed and verify that the BIOS
setup is confi gured for the fastest speed of RAM used. It is recommended to
use the same RAM speed for all DIMMs in the system.
3. Make sure you are using the correct type of DDR2 FBD (Fully Buffered) ECC
800/667/533 SDRAM (recommended by the manufacturer.)
4. Check for bad DIMM modules or slots by swapping a single module between
four slots and noting the results.
5. Make sure all memory modules are fully seated in their slots. As the interleaved
memory scheme is used, you must install two modules at a time, beginning
with Bank 1, then Bank 2, and so on (see Section 2-3).
6. Check the position of the 115V/230V switch on the power supply.
3-2 Technical Support Procedures
Before contacting Technical Support, please take the following steps. Also, please
note that as a motherboard manufacturer, Super Micro does not sell directly to end-

services. They should know of any possible problem(s) with the specifi c system
confi guration that was sold to you.
1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently Asked
Question' (FAQ) sections in this chapter or see the FAQs on our web site

) before contacting Technical
Support.
2. BIOS upgrades can be downloaded from our web site at

).
Note: Not all BIOS can be fl ashed; it depends on the modifi cations to the
boot block code.
