It is not sufficient to just plug multiple memory modules into their sockets to get dualchannel memory operation?computer users need to follow specific rules when adding memory modules to ensure that they get dual-channel memory performance. Otherwise, their system may fall back to single-channel memory mode. Why pay for a Ferrari and limit yourself to only using first gear?
Most dual-channel systems will have four memory DIMM sockets. Two sockets belong to channel A and the other two sockets to channel B.
In this context, “matching” modules means:
1. Both modules are the same capacity (e.g. both are 256MB, or 512MB)
2. Both modules are the same speed (e.g. both are PC2700 or PC3200)
3. Both have the same number of chips and module sides (e.g. both have the
same number of chips on the module, and both are either single-sided or
double-sided).
