should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. This allows the BIOS to read the SPD data and pr ogram the chipset to
accurately configure memory settings for optimum performance. If non-SPD memory
is installed, the BIOS will attempt to correctly configure the memory settings, but
performance and reliability may be impacted or the DIMMs may not function under the
determined fr eq u en cy.
Table 3 lists the supported DIMM configurations.

1.4.1 Memory Configurations
The 3rd generation Intel Core processor family and 2nd generation Intel Core processor
family processors support the following types of memory organization:
• Dual channel (Interleaved) mode. This mode offers the highest throughput for
real world applications. Dual channel mode is enabled when the installed memory
capacities of both DIMM channels are equal. Technology and device width can vary
from one channel to the other but the installed memory capacity for each channel
must be equal. If different speed DIMMs are used between channels, the slowest
memory timing will be used.
• Single chan nel (Asymmet ric) mode. This mode is equivalent to single channel
bandwidth operation for real world applications. This mode is used when only a
single DIMM is installed or the memory capacities are unequal. Technology and
device width can vary from one channel to the othe r. If different speed DIMMs are
used between channels, the slowest memory timing will be used.
• Flex mode. This mode provides the most flexible performance characteristics.
The bottommost DRAM memory (the memory that is lowes t within the system
memory map) is mapped to dual channel operation; the topm ost DRAM memory
(the memory that is nearest to the 8 GB address space limit), if any, is mapped to
single channel operation. Flex mode results in multiple zones of dual and single
channel operation across the whole of DRAM memory. To use flex mode, it is
necessary to populate both channels.
