Within the fields of digital electronics and computer hardware, multi-channel memory architecture is a technology that increases the data switch charge between the DRAM memory and the memory controller by adding more channels of communication between them. Theoretically, Memory Wave this multiplies the data charge by precisely the variety of channels current. Dual-channel memory employs two channels. Modern high-finish desktop and workstation processors such as the AMD Ryzen Threadripper series and the Intel Core i9 Extreme Version lineup help quad-channel memory.

Server processors from the AMD Epyc sequence and the Intel Xeon platforms give support to Memory Wave memory booster bandwidth beginning from quad-channel module structure to as much as 12-channel structure. 2011 for its LGA2011 platform. Microcomputer chipsets with even more channels were designed; for example, the chipset in the AlphaStation 600 (1995) supports eight-channel memory, however the backplane of the machine restricted operation to four channels. Dual-channel-enabled memory controllers in a Laptop system architecture use two 64-bit data channels. Twin-channel should not be confused with double information charge (DDR), during which knowledge trade happens twice per DRAM clock. The 2 applied sciences are impartial of each other, and lots of motherboards use both by using DDR memory in a twin-channel configuration. Twin-channel structure requires a dual-channel-capable motherboard and two or more DDR memory modules. The memory modules are put in into matching banks, each of which belongs to a distinct channel. The motherboard's guide will provide a proof of how to install memory for that exact unit.

A matched pair of memory modules could often be placed in the primary financial institution of each channel, and a distinct-capacity pair of modules in the second financial institution. Modules rated at different speeds could be run in twin-channel mode, although the motherboard will then run all memory modules at the pace of the slowest module. Some motherboards, nevertheless, have compatibility issues with certain manufacturers or fashions of memory when making an attempt to make use of them in twin-channel mode. Because of this, it is mostly advised to make use of equivalent pairs of memory modules, which is why most Memory Wave manufacturers now promote "kits" of matched-pair DIMMs. A number of motherboard manufacturers only assist configurations the place a "matched pair" of modules are used. Capacity (e.g. 1024 MB). Certain Intel chipsets support completely different capability chips in what they name Flex Mode: the capability that may be matched is run in twin-channel, while the remainder runs in single-channel. Speed (e.g. PC5300). If pace will not be the identical, the lower pace of the 2 modules shall be used.

Likewise, the upper latency of the two modules will likely be used. CAS (Column Deal with Strobe) latency, or CL. Number of chips and sides (e.g. two sides with four chips on each facet). Measurement of rows and columns. Theoretically any matched pair of memory modules could also be utilized in either single- or Memory Wave memory booster dual-channel operation, offered the motherboard supports this structure. With the introduction of DDR5, every DDR5 DIMM has two independent sub-channels. Theoretically, dual-channel configurations double the memory bandwidth when in comparison with single-channel configurations. This shouldn't be confused with double knowledge price (DDR) memory, which doubles the usage of DRAM bus by transferring knowledge each on the rising and falling edges of the memory bus clock alerts. Twin-channel was initially conceived as a approach to maximise memory throughput by combining two 64-bit buses right into a single 128-bit bus. That is retrospectively referred to as the "ganged" mode. 64-bit memory buses but permits impartial entry to each channel, in help of multithreading with multi-core processors.

RAID 0 works, when in comparison with JBOD. With RAID zero (which is analogous to "ganged" mode), it is as much as the additional logic layer to offer higher (ideally even) usage of all available hardware items (storage gadgets, or memory modules) and increased overall performance. Alternatively, with JBOD (which is analogous to "unganged" mode) it is relied on the statistical utilization patterns to make sure elevated general performance by way of even usage of all accessible hardware models. DDR3 triple-channel architecture is used in the Intel Core i7-900 collection (the Intel Core i7-800 collection solely support as much as twin-channel). The LGA 1366 platform (e.g. Intel X58) supports DDR3 triple-channel, normally 1333 and 1600Mhz, however can run at higher clock speeds on certain motherboards. AMD Socket AM3 processors don't use the DDR3 triple-channel architecture however as a substitute use dual-channel DDR3 memory. The identical applies to the Intel Core i3, Core i5 and Core i7-800 series, that are used on the LGA 1156 platforms (e.g., Intel P55).
