What is dual channel and quad channel? differences and which is better

When we talk about types of memory technology for computers or similar devices, we should mainly talk about RAM, Random Access Memory. These abbreviations refer to a type of computer memory that can be accessed randomly, that is, any byte of memory can be accessed, without having to access the previous bytes. This is the most common type of memory for printer computers or devices like printers. And DDR4 memories based on this mentioned memory.

RAM memory and its characteristics

Before we can talk about the differences of these technologies with respect to DDR4 memories (which are the most current), we will propose an explanation of what these memories mean and what they are. The complete abbreviation of these memories is DDR4 SDRAM, Double Data Rate type 4 Synchronous Dynamic Random-Access Memory, which translated means fourth generation double data transmission. This is a type of arbitrary access computer memory.

This is the standard developed mainly by the Samsung company for use with new technologies. The same as its predecessors, this is based on the use of DRAM technologies , RAM of cells built based on capacitors, they have 288 terminals, which are specialized for the cuts of the new generation main cards are Intel support. These memories are also known as DDR4 type DIMMs, thanks to the fact that they have physically autonomous connectors on both sides, just like the first DIMM standard.

DDR4 memories have 288 contacts for connection to the motherboard. They also have a notch in a strategic location of the connector, so that when inserting them there is no risk of placing them incorrectly or to prevent them from being inserted in the wrong slots. Likewise, like their predecessors, they may or may not occupy all of their memory slots. It also uses 30 nanometer technology for its manufacture, and has a supply voltage of 1.2-1.35 Volts, much lower than previous DDR versions.

The main advantage that DDR4 memories offer compared to its predecessors is the higher rate of clock frequency, and also of data transfer, the voltage is also much lower. These memories also point to a change in topology by ruling out triple-channel approaches, as each memory controller is connected to a single module.

Differences between Single, Dual and Quad Channel technologies in DDR4 memories

Next we are going to detail what each of its characteristics deals with in Single Channel, Dual Channel and Quad Channel. Any questions you can ask us!

Single Channel is fine, but remember as a couple it always goes better

Single Channel: refers to the use of a single signal at a certain bandwidth and frequency. For DDR4 memories it turns out to be one of the simplest technologies, working better on laptops or mini PCS, compared to other technologies that can be used on computers and devices with higher capacity. This traditionally works with 64 bits unlike the Dual and Quad Channel.

We recommend our guide to the best RAM memory of the moment.

Dual Channel or Dual channel and its excellent performance

Dual Channel: it is a technology for RAM memory that increases its performance by allowing the simultaneous passage to two different memory modules, which is done in blocks of 128 bits instead of the traditional 64 bits. This is accomplished through a second memory controller in the NorthBrigde or chipset. With this Dual Channel technology, graphics can access one memory module at the same time that the system enters another.

We recommend you from our guide to the best RAM memory.

For computers to run on Dual Channel, all memory modules must have the same capacity, speed, frequency, latency, and manufacturer, otherwise it may not work. This technology works perfectly with DDR4 memories, since they have the appropriate speed ranges to support this technology. Unlike single-channel technology, this increases memory performance almost twice as much in bandwidth, but in practice it does not go from 20 to 45% unfortunately.

Enthusiastic PCs with Quad Channel

Quad Channel: This is a technology that increases the speed of data transfer that takes place between DRAM memory and the memory controller, through the addition of communication channels between them. In general, the performance offered by this technology is almost equal to that of two channels, only with slight points ahead. But in DDR4 memories, the multiplicity of channels offers an 8MB cache, almost double the memory than with only two cores, and it also improves the bandwidth performance almost twice as much as the dual-channel ones. This technology is found at very affordable prices for DDR4 memories unlike previous DDRs.

In summary, the difference between Single Channel and Dual Channel is that we have double bandwidth. While the Quad Channel compared to the Dual Channel, the difference is noticeable in programs that involve a lot of RAM, for example rendering.

Another factor to take into account is that the RAM memory on the Intel platform has more speed than low latency, if we have both better, but speed is a key component, while if you play, the power of the processor is more important. and the graphics card. As always, we recommend first brands such as Corsair that are certified for almost all motherboards on the market and have the best components on the market.
