Losing the System’s Setup Confi guration
1. Ensure that you are using a high quality power supply. A poor quality power
supply may cause the system to lose the 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 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.

Procedures
Before contacting Technical Support, please take the following steps. Also, note
that as a motherboard manufacturer, Super Micro does not sell directly to end-us-
ers, so it is best to fi rst check with your distributor or reseller for troubleshooting
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 Ques-
tion' (FAQ) sections in this chapter or see the FAQs on our web site at (
http://
www.supermicro.com/support/faqs/
) before contacting Technical Support.
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 the DIMM modules are properly and fully installed.
2. Determine 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 recom-
mended to use the same RAM speed for all DIMMs in the system.
3. Make sure you are using the correct type of Registered ECC DDR-333/266
(PC2700/PC2100) SDRAM (*Please refer to Page 2-5 for the instruction on
DDR 333 DIMM population and installation.)
4. Check for bad DIMM modules or slots by swapping a single module between
two slots and noting the results.
5. Make sure all memory modules are fully seated in their slots. As an 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.
