What is DDR4 RAM?

DDR4 RAM stands for Double Data Rate 4 Random Access Memory. It is a type of computer memory where the operating system, application programs, and data in current use are kept.

This new version is the fourth generation of DDR RAM technology, succeeding DDR3. It provides high-speed data access to the processor and other hardware components.

Advantage of DDR4 RAM?

Fast Data Transfer Rates

The DDR4 RAM operates at higher clock frequencies than DDR3 RAM. Clock speed determines how fast data can be transferred between RAM and the processor. Due to its high frequencies, data is transferred at a speed of approximately 1600 to 3200 MT/s.

DDR4 has a larger prefetch size, causing it to fetch and transfer more data per clock cycle than DDR3. Each allows more efficient use of clock cycles, contributing to higher data transfer rates.

It features improvements to the memory bus architecture, enabling more efficient communication between the memory controller and RAM modules, thereby reducing latency and increasing bandwidth.

It is also designed to work with multiple banks and channels simultaneously. This parallel operation enables the system to process and transfer multiple pieces of data simultaneously, further increasing data throughput.

Increased Capacity

DDR4 RAM comes with higher storage capacity than previous generations. It has a 64GB maximum capacity per memory module, whereas DDR3 only has 16 GB. Its 16 GB and 32 GB are very common and are used the most.

Its large memory capacity handles intensive tasks like professional editing, gaming, and multitasking efficiently. Due to the increased capacity of RAM, the system’s performance is also better.

Higher Bandwidth

DDR4 has a higher bandwidth compared to the previous generation. Bandwidth refers to the amount of data transferred between RAM and the processor in a certain period. Its increased bandwidth allows for transmitting more data between RAM and the processor, resulting in faster data transfer.

This increased bandwidth is especially beneficial for tasks like graphics-intensive gaming, video editing, and multitasking, requiring quick and efficient data processing. This facilitates faster data transfer, leading to smoother and more responsive performance.

Due to the high bandwidth, the system retrieves and uses the necessary data quickly, increasing the computer’s performance.

Lower Power Consumption

DDR4 RAM provides higher levels of performance yet consumes less power than its previous generation. Due to low power consumption, the battery of the system lasts longer. Even when the computer does more intensive work or multitasking, it consumes less power, which is a very good thing for a gaming laptop because the battery of a gaming laptop drains very quickly.

Due to its low power consumption, heat production is also very low. Cooler operating temperatures are beneficial to the overall stability and longevity of computer components.

On-Die Termination

The On-die termination (ODT) is a feature integrated into DDR4 RAM modules. On-die termination means that the resistors responsible for terminating electrical signals are physically located on the same silicon chip as the memory cells rather than being placed externally on the memory bus.

ODT reduces signal reflections within the memory system. Signal reflection occurs when electrical signals encounter an impedance mismatch with the memory bus. ODT reduces these reflections by providing controlled termination directly on the memory die, resulting in excellent signal quality.

Additionally, it increases the stability of high-speed memory systems, which is crucial in systems where DDR4 RAM operates at increased frequencies; stability becomes essential.

Improved Error Correction

DDR4 RAM detects and corrects errors during data storage or retrieval processes. Data integrity and reliability are increased due to its better error correction. Advanced error correction is especially important when data accuracy is paramount.


Data transfer in DDR4 RAM is much faster, transferring data at almost twice the speed of DDR2. DDR4 transfers data at a minimum of 2133 MT/s to a maximum of 5133 MT/s, while DDR2 transfers data at a minimum of 400 MT/s to a maximum of 800 MT/s.
