Intel Desktop Board DH61SA Technical Product Specification 
18 
Intel assumes no responsibility that the memory installed on the desktop board, if 
used with altered clock frequencies and/or voltages, will be fit for any particular 
purpose.  Check with the memory manufacturer for warranty terms and additional 
details.

1.6.1  Memory Configurations 
The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium 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 channel (Asymmetric) 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 other.  If different speed DIMMs are 
used between channels, the slowest memory timing will be used.
