Should I take dual channel vs single channel ram ? Which is better?
With the update of games and software day by day, the demand for RAM is also increasing. At present most of the PC builds have 8-16GB RAM. Those who go to build a PC with 8 or 16 GB of RAM, just then looking at the budget comes to mind a question.
Should I take dual channel vs single channel ram linus?
how to identify single channel and dual channel ram?
The main difference between dual channel vs single channel ram RAM
The RAM of a system is controlled by a specific circuit Known as 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 refers to the number of bits (electrical wires) that make up the bus.
Or, the RAM and the memory controller are connected to each other via a series of wires known as the memory bus. A series of cables has three parts namely: –
The function of the control wires is to transmit commands to the memory modules and capture information about the type of operation being performed by the system.
The function of data wires is to carry data that is being read from memory to memory controller or 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 1333Mhz. Then of 2666Mhz.
Even if RAM is installed, it is only 1333Mhz in the system Can be utilized, thus underlocking the memory controller RAM. So, what happend in single channel ram in dual channel motherboard!
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. This means that a stick of RAM can transfer 64-Bit data during each Clock Cycle transfer. Or, a single channel RAM transfers data through a series of cables with a total width of 64-bit.
However, if you want to know about Gaming mouse vs regular mouse, then check it out!
what is dual channel ram?
Dual-Channel Memory Architecture:
Two stick units of RAM (64 × 2 = 128) act as bit data channels. This means that two sticks of RAM can transfer 128-bit data while each clock cycle is being transferred. Or, a single channel RAM transfers data through a series of wires with a total width of 128-bit.
If you look at the image, you can see that both channels support data from D00 to D63 on the 64-Bit port. Again on the second channel the data from D64 to D127 is supported on the 64-Bit port.
As a result, the system treats the channel width as a total of 128-bit width instead of 64-bit. Quad channel vs dual channel is also an important issue to discuss!
single channel vs dual channel ram Bandwidth
Bandwidth is the maximum theoretical transfer rate of a communication channel. The formula for determining dual channel ram ddr4 bandwidth is:
Memory Bandwidth = (DDR clock rate x data bus width) / 8
However, dual channel vs single channel reddit is also an important things to cover! and dual channel vs quad channel is also quite importan!
Single Channel Memory Bandwith:
As we know, a stick of RAM serves as a single 64-bit data channel. This means that a stick of RAM can transfer 64-Bit data during each Clock Cycle transfer.
Or, a single channel RAM transfers data through a series of cables with a total width of 64-bit. Therefore, according to the formula, hold,
DDR Clock Rate = 3200mhz
Data Bus Width = 64-bit
Single Channel Memory Bandwith = (3200 × 64) / 8
= 204,800 MB / s
= 200 GB / s
However, ram is quite importan if you are playing games like Apex Legends!
Dual-Channel Memory Bandwith
As we know, two stick units of RAM act as single (64 *2 = 128) bit data channels.
This means that two sticks of RAM can transfer 128-bit data while each clock cycle is being transferred. Or, a single channel RAM transfers data through a series of wires with a total width of 128-bit.
Therefore, according to sources,
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 enjoy the full performance of your system.
