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
An example of a Technical Support form is on our web site at
(http://www.supermicro.com/support/contact.cfm).
4. Distributors: For immediate assistance, please have your account number ready
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 ECC DDR2-400 (PC3200) 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 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.
