3. 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

1. Make sure that 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 that you are using the correct type of DDR2 FBD (Fully Buffered) ECC

533/667 SDRAM (*recommended by the manufacturer.)

4. Check for bad DIMM modules or slots by swapping a single module between

four 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 four modules at a time,

beginning with Branch 0, then Branch 1, and so on (see Page 2-6).

6. Check the position of the 115V/230V switch on the power supply.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also, note that

as a motherboard manufacturer, Supermicro does not sell directly to end-users, 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

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 (

) before contacting Technical 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; it depends on the modiﬁ cations to the

boot block code.

3. If you still cannot resolve the problem, include the following information when

contacting Supermicro for technical support:

• Motherboard model and PCB revision number

• BIOS release date/version (this can be seen on the initial display when your
