Should I take single stick or dual-stick RAM? Which is better?

RAM (‌‌‍‍ Random Access Memory)

Day to day games and software updates
As it grows, so does the demand for RAM.
Currently most of the PC build time is 8-.
With 16GB RAM.  Those 8 or 16GB
You can build a PC with RAM,

Just then a question came to mind looking at the budget.

Should I take single channel or dual channel RAM?

The main difference between single channel & dual channel RAM?

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

 Data Bus Width:

A data bus has many different defining features but most of them

One of the important is its width.  The width of a data bus is bit (electric Cables) refers to the number that makes up the bus.  Or, RAM and memory controller.

The wires are connected to each other via a series of memory basses known as.  A series of cables has three parts namely:

 ★ Control ★ Data ★ Address

The function of control wires is to transmit commands to and from memory modules

contains information about the type of operation being performed through the system.

The function of data wires is to carry data from memory to memory controller. it is either read or is being written from memory controller to memory.

A memory controller controls the clock speed of a system's RAM.  Such as: -

If a system or motherboard's memory controller fixes

Will support up to a maximum of 1333Mhz.  Then of 2666Mhz

Even if RAM is installed, it is only 1333Mhz in the system

This way the memory controller underlocks the RAM.

Single Channel vs Dual Channel Memory

Architecture:

Currently both Intel and AMD support dual channel memory in their systems

For better performance.

Single Channel Memory Architecture:

A stick of RAM serves as a single 64-bit data channel.

A stick can transfer 64-Bit data during each Clock Cycle transfer.  Or, a single channel RAM data through a series of wires transfers to a total width of 64-bit.

Dual-Channel Memory Architecture: 

Two stick units of RAM (64 × 2 = 128) act as bit data channels.

That means two sticks of RAM can transfer 128-Bit data every Clock

Cycle transfer time.  Or, a single channel RAM data

Transfers through a series of wires with a total width of 128-bit.

If you look at the image you will see that both channels have data from D00 to D63

Supports 64-Bit port.  Again on the second channel the data from D64 to D127 is on the 64-Bit port.

As a result, the system has increased the channel width to a total of 128-bit width instead of 64-bit.

Single Channel vs Dual Channel Memory

Bandwidth-

Bandwidth is the maximum theoretical transfer rate of a communication channel.

The formula for determining RAM bandwidth is:

Memory Bandwidth = (DDR clock rate x data bus width) / 8

Single Channel Memory Bandwith:

We know,

A stick of RAM serves as a single 64-bit data channel.  That is Radham's

A stick can transfer 64-Bit data every Clock Cycle transfer

Time.  Or, a single channel RAM data through a series of wires

Transfers to a total width of 64-bit.  Therefore, according to sources,

DDR Clock Rate = 3200Mhz

Data Bus Width = 64-bit

Single Channel Memory Bandwith =

(3200 × 64) / 8

                                            = 204,800 MB / s

                                            = 200 GB / s

Dual-Channel Memory Bandwith:

We know

Two stick units of RAM (64 × 2 = 128) act as bit data channels.

That means two sticks of RAM can transfer 128-Bit data every Clock

Cycle transfer time.  Or, a single channel RAM data

Transfers through a series of wires with a total width of 128-bit.

 Therefore, according to sources,

 Hold on,

 DDR Clock Rate = 3200Mhz

 Data Bus Width = 128-bit

 Single Channel Memory Bandwith = (3200 × 128) / 8

                                                   = 409,600 MB / s

                                                   = 400 GB / s

Nowadays, it is best to build a PC with Dual Channel Memory for gaming, productivity work and to enjoy the full performance of your system.
