The amount of performance gain when using dual channel memory mode is around 10% – 15% only (also depends on various factors, PC & Memory specs). Theoretically dual channel architecture doubles the throughput and bandwidth, but in real world the performance gain is not too much. Performance Gain by using Dual Channel Memory Mode Requirements for Dual Channel Memory Mode Configuration Also Modern CPUs like Intel i3, i5 & i7 has memory controller integrated in them which leads to faster access of data and it also helps in reducing memory latency. Some modern day Processors like i7 can support triple channel and quad channel memory configuration.
2, 4, 6 etc.Ī motherboard supporting dual channel memory configuration has its memory slots color coded to indicate that you should put memory of same type in the slots with same color to run or use them in dual channel mode.Ĭolor Coded Memory Slots indicating Channels To run memory in dual channel mode the two RAM should of same capacity, make and speed (not necessary but preferred to avoid issues). DDR, DDR2, DDR3 RAM supports dual channel memory mode. You can run any two identical types of RAM in dual channel mode.
It must be noted that dual channel architecture is a motherboard feature or technology and is independent of RAM types. This leads to increase in overall performance of the system. Here we can say that there is a simultaneous two way parallel communication between the memory controller and RAM. So when the memory is operating in dual channel model then one channel is used to handle the reading and writing of data and other channel is used for loading, refreshing, and housekeeping functions.
