Chapter 1
The following conditions
must
be met:
T
Matched DIMM configuration in each channel
T
Same Density (128MB, 256MB, 512MB, etc.)
T
Same DRAM technology (128Mb, 256Mb, or 512Mb)
T
Same DRAM bus width (x8 or x16)
T
Both either single-sided or dual-sided
T
Matched in both Channel A and Channel B memory channels
T
Populate symmetrical memory slots (Slot 0 or Slot 1)
The following conditions do
not
need to be met:
T
Same brand
T
Same timing specifications
T
Same DDR speed
Symmetrical DIMMs must be identical for optimal performance
T
Same DIMM density, e.g. 128MB, 256MB, 512MB, etc.
T
Same DRAM Technology, e.g. 128M-bit, 256M-bit, etc.
T
Same DRAM bus width, e.g. x8 or x16
T
Single Sided or Dual Sided
NOTE:
Note: Memory interface speed will be set to lowest speed of memory populated
Memory Characteristics
Optimize performance for single or dual channel is obtained with matched DIMM population
Table below shows DIMMs with same Organization and Density, but are non-matching as bus width,
technology and/or external banks are different
T
Mixing these DIMMs will put platform into single channel mode
