3-3 Frequently Asked Questions

Question: What type of memory does my motherboard support?

Answer: The X8ST3-F/X8STE supports up to 24 GB of unbuffered ECC
or non-ECC DDR3 (1.5V) 1333/1066/800 MHz, two-way interleaved or non-
interleaved SDRAM. See Section 2-4 for details on installing memory.

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?

Since the memory controller is integrated into the CPU, the memory speed
depends on the installed CPUs QPI (QuickPath Interconnect) 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.

Question: How do I update my BIOS?

Answer: It is recommended that you do not upgrade your BIOS if you are not
experiencing any problems with your system. Updated BIOS files are located
on our web site at
