"Intel Dual-Channel DDR Memory Architecture White Paper" (PDF) (Rev.5 Other tests performed by casino games free roulette TweakTown on the same subject showed no significant differences in pengar insättning swedbank performance, leading to a conclusion that not all benchmark software is up to the task of exploiting increased parallelism offered by the multi-channel memory configurations.When two memory modules are installed, the architecture will operate in a dual-channel mode; when three memory modules are installed, the architecture will operate in a triple-channel mode.A matching pair needs to match in: Capacity (e.g.Some motherboards, however, have compatibility issues with certain brands or models of memory when attempting to use them in dual-channel mode.In its tests, dual channel gave at best a 5 speed increase in memory-intensive tasks.6 Ganged versus unganged edit Dual-channel was originally conceived as a way to maximize memory throughput by combining two 64-bit buses into a single 128-bit bus.The architecture can be used only when all four memory modules (or a multiple of four) are identical in capacity and speed, and are placed in quad-channel slots.11 12 Triple-channel architecture edit Operation edit DDR3 triple-channel architecture is used in the Intel Core i7 -900 series (the Intel Core i7-800 series only support up to dual-channel).
Theoretically this multiplies the data rate by exactly the number of channels present.
The same applies to the Intel Core i3, Core i5 and Core i7-800 series, which are used on the LGA 1156 platforms (e.g., Intel P55 ).

13 With raid 0 (which is analogous to "ganged" mode it is up to the additional logic layer to provide better (ideally even) usage of all available hardware units (storage devices, or memory modules) and increased overall performance.
X58 Product Brief (PDF Intel a b Desktop Boards Triple Memory Modules, Intel "Core i7 Family Product Comparison".Dual channel should not be confused with double data rate (DDR in which data exchange happens twice per dram clock.Please, turn your attention, rename the bookmark, delete from my manuals?AlphaStation 600 (1995) supports eight-channel memory, but the backplane of the machine limited operation to four channels.Typical systems are recommended to run in unganged mode to benefit from the additional parallelism generated by using the DCTs independently.AMD processors for the C32 platform and Intel processors for the LGA 1155 platform (e.g., Intel Z68 ) use dual-channel DDR3 memory instead.Several motherboard manufacturers only support configurations where a "matched pair" of modules are used.8 The test results published by Tom's Hardware had a discrete graphics comparison.Identical memory modules are not required, but are often recommended for best dual-channel operation.

Dual-channel memory employs two channels.
