3-2 Technical Support Procedures
Before contacting Technical Support, please take the following steps. Also,
note that as a mainboard manufacturer, Supermicro does not sell directly to
end-users, so it is best to first check with your distributor or reseller for
troubleshooting services. They should know of any possible problem(s)
with the specific system configuration 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/techsupport.htm) before contact-
ing Technical Support.
2. BIOS upgrades can be downloaded from our web site at:
http://www.supermicro.com/techsupport/download.htm.
Note: Not all types and versions of BIOS can be flashed, depend-
ing on the modifications to the boot block code.
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 the RIMM modules are properly and fully installed for the
amount of memory desired and RAMBUS terminators are installed in
any unused channel.
2. Determine if different speeds of RIMMs have been installed and verify
that the BIOS setup is configured for the fastest speed of memory
used. It is recommended that all RIMMs in the system have the same
speed.
3. Make sure you are using PC600 or PC800 compliant RDRAM.
4. Check for bad RIMM modules or slots by swapping modules among
slots and noting the results.
5. Make sure all memory modules are fully seated in their slots.
6. All RDRAM must be of the same speed (e.g. PC600 or PC800). Addi-
tionally, the size of the memory bank sticks (e.g. 256 MB) must be
the same in any given memory channel.
