Note 4:
For Microsoft Windows users: Microsoft implemented a design change
in Windows XP with Service Pack 2 (SP2) and Windows Vista. This change
is specific to the Physical Address Extension (PAE) mode behavior which
improves driver compatibility. For more information, please read the following
article at Microsoft’s Knowledge Base website at: http://support.microsoft.
com/kb/888137.
Note 5
: Up to three Core i7 1600 XMP DDR3 DIMM Modules are supported
on the C7X58 motherboard (one DIMM per channel). However, XMP mode will
only work if a Core i7 Extreme Edition CPU and Core i7 XMP memory are both
installed. See Page 4-11 to activate XMP mode in the BIOS.
