Quad channel

Quad-Channel is a term used in computer storage technology.

power

Thus, the ability of is PC - chip sets and memory controllers designated, four memory to operate parallel modules of the same capacity, thereby achieving a higher data transfer rate and an associated increase in performance. This requires four separate buses from the memory controller to the individual modules. Quad-Channel represents a further development of the memory technologies Dual Channel (Intel / AMD) and Triple Channel (Intel).

effect

The method, which already doubled the transfer rate with dual-channeling by accessing at least two modules with a delay, is now carried out with four modules, which leads to a four-fold increase in the possible transfer rate. The latency times of the memory are therefore no longer so heavily involved in the access time, which ultimately leads to the increase in performance. In order for this procedure to work properly, four modules with exactly the same specification must always be used.

history

The first quad-channel capable motherboards were available with the introduction of AMD's Magny-Cours processor in early 2010. Intel mainboards with the X79 chipset followed at the end of 2011. Four memory modules of the same design and a compatible processor (Magny-Cours or Sandy Bridge-E or later Bulldozer or Ivy Bridge) were essential for the use.
