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 installed and fully seated in

the slots.

2. You should be using unbuffered, ECC/Non-ECC DDR2-677/533 memory (see

the next page). Also, it is recommended that you use the same memory

speed for all DIMMs in the system. See Section 2-4 for memory limitations.

3. Check for bad DIMM modules or slots by swapping modules between slots

and noting the results.

4. Check the power supply voltage 115V/230V switch.

Losing the System’s Setup Conﬁ guration

1. Please be sure to use a high quality power supply. A poor quality power sup-

ply may cause the system to lose the CMOS setup information. Refer to

Section 1-6 for details on recommended power supplies.

2. The battery on your motherboard may be old. Check to verify that it still sup-

plies ~3VDC. If it does not, replace it with a new one.

3. If the above steps do not ﬁ x the Setup Conﬁ guration problem, contact your

vendor for repairs.

3-2 Technical Support Procedures

Before contacting Technical Support, please make sure that you have followed all

the steps listed below. 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 that was sold to you.

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 (

http://

www.supermicro.com/support/faqs/

) 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; some can be ﬂ ashed, depending on the

modiﬁ cations to the boot block code.
