supplies ~3VDC. If it does not, replace it with a new one.
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
Make sure the DIMM modules are properly and fully installed. Check if
DIMMs of different speeds or types have been installed. Also make sure 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.
Make sure you are using the correct type of Single-Rank, Registered ECC
DDR2 667/533 SDRAM (recommended by the manufacturer.)
Check for bad DIMM modules or slots by swapping a single module between
four slots and noting the results. 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 DIMM 1A, then DIMM 2A, and
so on (see Section 2-3). Check the position of the 115V/230V switch on the
power supply.

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.
Please go through the ‘Troubleshooting Procedures’ and 'Frequently Asked
Question' (FAQ) sections in this chapter or see the FAQs on our web site (http://
www.supermicro.com/support/faqs/) before contacting Technical Support.
BIOS upgrades can be downloaded from our web site at http://www.supermicro.
com/support/bios/.
If you still cannot resolve the problem, include the following information when
contacting Super Micro for technical support:
Motherboard model and PCB revision number
BIOS release date/version (this can be seen on the initial display when your
system fi rst boots up)
