3-2 Technical Support 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
Question' (FAQ) sections in this chapter or see the FAQs on our web site
(
http://www.supermicro.com/support/faqs/
) before contacting Techni-
cal Support.
2. BIOS upgrades can be downloaded from our web site at
(http://www.supermicro.com/support/bios/ ).
Note: Not all BIOS can be fl ashed depending on the modifi cations to the boot
block code.
3. 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)
•System confi guration
NOTE
If you are a system integrator, VAR or OEM, a POST diagnostics
card is recommended. For I/O port 80h codes, refer to Appendix B.
Memory Errors
1. Make sure that all 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 that you are using the correct type of Registered, ECC DDRII 400
SDRAM (*recommended by the manufacturer.)
4. Check for bad DIMM modules or slots by swapping a single module between
two slots and noting the results.
5. Make sure that all memory modules are fully seated in their slots. As an in-
terleaved memory scheme is used, you must install two modules at a time,
beginning with DIMM #1A, then DIMM #1B, and so on (see Section 2-3).
6. Check the position of the 115V/230V switch on the power supply.
