Take Single Stick RAM or Dual-Stick RAM? Which one is better?

RAM (Random Access Memory)

Demand and demand for RAM is increasing day by day with games and software being updated.
Currently most of the PC builds 8-16GB of RAM. For those who go to build a PC with 8 or 16GB of RAM, a question comes to mind when looking at the budget.
Will RAM be Single Channel or Dual Channel Nib? What is the main difference between Single Channel & Dual Channel RAM?

The RAM of a system is controlled by a specific circuit known as a Memory Controller.

Data Bus Width:

A data bus has many different defining features, but one of the most important is its width. The width of a data bus is the number of bits (electric cables) that make up the bus. Or, RAM and memory controller
They are connected to each other through a series of wires known as memory buses. A series of wires has three parts namely: -

★ Control ★ Data ★ Address

The function of the control cables is to transmit commands to the memory modules and capture information about what kind of operation is being done through the system. The function of data wires is to carry data that is read from memory to the memory controller or written from memory controller to memory.

The memory controller controls the clock speed of a system's RAM. For example: if a system or motherboard's memory controller supports up to a maximum of 1333Mhz. Then installing 2666Mhz of RAM, it can only use 1333Mhz speed on the system, thus the memory controller overlaps the RAM.

Single Channel vs Dual Channel Memory Architecture

Take Single Stick RAM or Dual-Stick RAM? Which one is better?

Both Intel and AMD currently support dual-channel memory on their systems
For better performance.

Single Channel Memory Architecture:

A stick of RAM acts as a single 64-bit data channel. That's RAM
A Stick 64-Bit Data Transfer Can Transfer Each Clock Cycle During Transfer Or, a single channel transmits the RAM data through a cable series with a total width of 64-bit.

Dual-Channel Memory Architecture:

The two RAM sticks act as single (64 × 2 = 128) bit data channels.
That is, two clocks of RAM can transfer 128-bit data to each Clock
During the Cycle Transfer. Or, a single channel transmits RAM data through a cable series with a total width of 128-bit.

If you look at the image, you will see that both channels transports data from D00 to D63 to a 64-bit port. Again, data from the D64 to D127 channels in the 64-bit bit ports on the second channel. As a result, the system considers the channel width to be 128-bit wide instead of 64-bit.

Single Channel vs Dual Channel Memory Bandwidth

Bandwith

Bandwidth is the maximum theoretical transfer rate of a communication channel.
There is a formula for determining the bandwidth of the RAM:
Memory Bandwidth = (DDR clock rate x data bus width) / 8

Single Channel Memory Bandwith:

We know,
A stick of RAM acts as a single 64-bit data channel. That's RAM
A Stick 64-Bit Data Transfer Can Transfer Each Clock Cycle During Transfer Or, a single channel transmits the RAM data through a cable series with a total width of 64-bit.

Therefore, according to the formula,

Hold on,
DDR Clock Rate = 3200Mhz
Data Bus Width = 64-bit

Single Channel Memory Bandwith = (3200 x 64) / 8
= 204,800 MB / s
= 200 GB / s

Dual-Channel Memory Bandwith:

We know,
The two RAM sticks act as single (64 × 2 = 128) bit data channels.
That is, two clocks of RAM can transfer 128-bit data to each Clock
During the Cycle Transfer. Or, a single channel RAM data
Transmits via a cable series whose total width is 128-bit.

Therefore, according to the formula,

Hold on,
DDR Clock Rate = 3200Mhz
Data Bus Width = 128-bit

Single Channel Memory Bandwith = (3200 x 128) / 8
= 409,600 MB / s
= 400 GB / s

At present, it is best to build a PC with Dual Channel Memory for all gaming, productivity functions and enjoy your system's full performance.
