Frequently Asked Questions

Question: What type of memory does my motherboard support?
Answer: The X8STi/X8STi-F/X8STi-3F/X8STi-LN4 supports up to 24 GB of
unbuffered ECC or non-ECC DDR3 (1.5V) 1333/1066/800 MHz SDRAM. See
Section 2-4 for details on installing memory. (Note: Both ECC and Non-ECC
memory modules are supported. However, using ECC or Non-ECC memory
depends on the CPU installed on the motherboard.)
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, memory speed de-
pends on the installed CPUs QPI (QuickPath Interconnect) rating. Please check
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.
