Chapter 3: Troubleshooting
Note: Not all BIOS can be flashed. Some cannot be flashed; it depends
on the modifications to the boot block code.
3. If you've followed the instructions above to troubleshoot your system, and still
cannot resolve the problem, then contact Supermicro's technical support and

3-3 Frequently Asked Questions
Question: What type of memory does my motherboard support?
Answer: The X8SAX/C7X58 supports up to 24 GB of unbuffered ECC or
non-ECC (1.5V) DDR3 1333/1066/800 MHz, two-way interleaved or non-
interleaved SDRAM. Additionally, the C7X58 also supports 1600 XMP memory
when an Extreme Edition CPU is installed. See Section 2-4 for details on
installing memory.
Note: Please enable XMP under Performance Tuning Mode in the BIOS to
enable 1600 XMP operation on the C7X58 (See page 4-11). You must have an
Extreme Edition CPU installed for this feature to work. Otherwise, the system
will fall back to a lower bus speed regardless of the BIOS settings.
Question: I installed 1333/1066 MHz memory, why doesn't my motherboard
(X8SAX, C7X58, X8ST3-F/E or X8STi family) run the memory at 1333/1066
MHz?
The memory speed depends on the installed CPUs QPI rating. Please check
your CPU specifications. For example, to support 1333 MHz memory, the
CPU's QPI should be 6.4GT/S. A lower QPI number means that it will support
slower memory. More information may be found at www.intel.com.
