Tips on how to choose the best DDR4 RAM

Random access memory (RAM) is a piece of hardware that serves as a temporary storage area that quickly accesses the required data. RAM affects the speed at which your system can run various programs. To keep up with the development of programs or software, the quality of RAM must always be improved.

The difference between DDR4 RAM and DDR3 RAM you need to know

In general, the difference between DDR4 and DDR3 RAM versions lies in their quality. DDR4 has an improved quality from the DDR3 version. This can be seen from the advantages of DDR4 performance as follows.

1. Larger capacity: DDR4 has a capacity of 4 to 16 GB per chip, in contrast to DDR3 which has a capacity of 512 MB to 8 GB per chip.

2. Faster data processing capability: DDR4 can process data from 2133 to 4800 MHz. This is much faster than the previous version which was only able to process data with a maximum speed of 2133 MHz.

3. Lower current: DDR3 has a mains voltage of 1.35 to 1.5 volts. This point is increased by DDR4 so the voltage is 1.2 volts on average. Thus, the electrical power consumed is also lower.

Then, what about the price? Judging from the quality offered, it is natural that DDR4 has a higher price than DDR3. However, the cost is well worth it considering that most high-end PC and laptop motherboards are also compatible with DDR4 RAM. Therefore, there is no harm in spending more to buy a sophisticated DDR4.

Tips on how to choose the best DDR4 RAM for you

After you understand the quality of DDR4, now I will explain tips on how to choose the best DDR4 RAM for you.

Choose DDR4 RAM according to your device type

RAM is a device that you will install on the motherboard. Well, desktop PCs and laptops have different types of motherboards. The difference lies in the number of pins provided by the motherboard. For that, you must choose the right type of RAM, as follows.

1. RAM SO-DIMM: RAM small outline dual inline memory module DDR4 has 260 pins. RAM of this size is generally used on laptops or notebooks.

2. RAM DIMM: The dual inline DDR4 memory module RAM has a pin count of 288 which is commonly used in desktop PCs.

This difference in the number of pins also means that SO-DIMM RAM cannot be installed on a motherboard that supports RAM DIMMs, and vice versa. Therefore, double-check your RAM type based on the device you are using.

Make sure your DDR4 RAM speed is compatible with the motherboard

Now that you can differentiate between SO-DIMMs and DIMMs, you now need to consider the compatibility of the motherboard with the RAM you are going to choose. Usually modern motherboards are compatible with DDR4 RAM capacity. However, you need to further research its compatibility with RAM speed. I will explain this compatibility in the following two points.

1. Check the DDR4 RAM frequency to see how fast it works: The RAM frequency determines the speed at which it processes data (reads and writes data) at each clock cycle per second. The size is rated in MHz. The higher the number, the more cycles that can be processed in one second and this means your computer will run faster.

For normal use, RAM with a speed of 2400 MHz is sufficient. However, if you plan to overclock, choose RAM whose frequency is more than 2400 MHz. Multiple RAMs from Intel offer easy overclocking with the XMP Profile feature. This feature is useful for configuring your device automatically. Unfortunately, this feature is rarely compatible with AMD motherboards.

2. CAS Latency, to assess how long DDR4 RAM takes to process commands: Column Access Strobe (CAS) latency or CL is the time delay required by RAM from receiving to executing a command. RAM with a combination of low frequency and high CL can work faster. The results have been proven when this component is compared with high frequency RAM with low CL.

Choose DDR4 RAM capacity according to your needs

Finally, you need to adjust the RAM capacity to the intended use of your system. We briefly describe three ideal usage goals according to RAM capacity.

1. 4 GB RAM for daily use: DDR4 with a capacity of 4 GB is suitable for systems used for daily use. This capacity is large enough and convenient to run standard programs with maximum performance.

2. 8GB RAM for gaming or editing: 8GB DDR4 is perfect for systems running heavier programs like gaming. Judging from the price and quality that is not excessive, 8 GB RAM is the sweet spot for today's gaming.

3. 16 GB RAM for future use: 16 GB DDR4 is definitely of great quality making it easy to run any program today. The 16 GB capacity will also be relevant for some time to come in line with the growing system needs to run more updated programs.

So, RAM capacity vs speed, which one should come first?

The thing that is often worried about is the capacity and speed of RAM. If you have to choose, we recommend that you prioritize RAM capacity over speed.

If you have to choose between super-fast 8GB RAM and 16GB RAM at standard speeds, go for the 16GB one. This is because the difference in RAM speed is not as influential as the difference in capacity. What's more, the difference in RAM speed can usually only be felt on high-end spec systems.


DDR4 RAM is indispensable for modern computer systems. The quality is very qualified to run heavy and complex programs. Even though it is sophisticated, it still requires accuracy in choosing it so that the costs incurred are balanced and not wasteful.

The capacities of 4 GB, 8 GB, and 16 GB have their respective advantages. Make sure you choose the one that fits your needs and is compatible with your motherboard!
