How much RAM is enough for HP EliteBook 840 G3?

Having enough RAM is essential for optimal performance on a laptop, especially when it comes to multi-tasking and running high-intensity applications.

If you’re an HP EliteBook 840 G3 user, you might also wonder how much RAM do you need in an HP EliteBook 840 G3?

This article will explore the the RAMs available for this particular model, their capacity and compatibility, as well as discuss what type of performance can be expected with different amounts of RAM installed.

Why Having Enough RAM is Important?

RAM is the computer’s working memory, which stores information and instructions while the processor is running. It’s a temporary storage space, much like your laptop’s hard drive but with faster access speeds and better multitasking capabilities.

When you have too little RAM on board, programs that require more RAM to run will run slowly or may even crash.

In addition to slow program performance and crashes caused by insufficient RAM, another major problem is the inability to run multiple programs simultaneously. This can greatly hinder productivity, especially in today’s fast-paced work environment where multitasking has become a necessity.

With enough RAM, however, running multiple programs at the same time becomes a breeze. You can switch between applications, open new ones, and work on various tasks all without suffering from slowdowns or freezes.

This is because a larger RAM capacity allows your laptop to store more data in its working memory, preventing it from having to constantly retrieve information from the slower hard drive.

In general, more RAM means better performance, faster speeds, and multiple programs at once. It helps build an environment where multiple applications can run efficiently at the same time with just the right amount of power to do so.

RAM Compatibility of HP EliteBook 840 G3

Before we answer how much RAM is enough for HP EliteBook 840 G3, we first need to address what types of RAM are compatible with this particular model.

The HP EliteBook 840 G3 is compatible with DDR4-2133 SDRAM memory modules and can support up to 32GB of RAM when configured with two 16GB sticks which is the max RAM configuration for HP EliteBook 840 G3.

When it comes to configuring RAM for your HP EliteBook 840 G3, there are several configurations available to you.

  • 4GB Total Memory (1 x 4GB)
  • 8GB Total Memory (2 x 4GB)
  • 8GB Total Memory (1 x 8GB)
  • 16GB Total Memory (2 x 8GB)
  • 16GB Total Memory (1 x 16GB)
  • 32GB Total Memory (2 x 16GB)

Additionally, it’s best practice to use matching memory sticks in order for the system to achieve its maximum speed and performance.

While it may be tempting to mix and match different memory sizes and speeds, doing so can result in slower system performance and potential instability issues.

How much RAM is enough for HP EliteBook 840 G3?

Once you’ve determined which type of RAM your laptop requires, then you can decide how much is actually necessary for optimal performance.

You can choose to go with a smaller 4GB configuration if you have minimal computing needs but I wouldn’t recommend going for a 4GB variant in today’s world as your system will eat up that RAM and cause you many performance issues.

Depending on your needs and usage habits, 8GB RAM for HP EliteBook 840 G3 may be enough if you do casual work like web browsing, streaming videos, and light multitasking.

16GB RAM for HP EliteBook 840 G3 is the option I would recommend going for in today’s world but only if your needs require it. If you plan on running resource-intensive applications such as video editing or intensive web browsing, along with multitasking, then 16GB may be the best option for you.

32GB is overkill for most users and EliteBook 840 G3’s CPU and GPU might not be able to utilize 32GB RAM to the fullest in a lot of cases. But it can come in handy when it comes to editing large files or working with complex databases.

Keep in mind that having too much RAM won’t really help overall performance if the processor isn’t powerful enough; make sure that EliteBook 840 G3 has adequate processing power before investing in 32GB memory modules.

Dual Channel Memory

Why Dual Channel RAM is better than Single Channel RAM?

Whatever RAM capacity you go for, I highly recommend going for a dual-channel memory configuration. This means utilizing two identical memory sticks instead of just one, which can greatly enhance the performance of your laptop.

One of the main benefits of using dual-channel memory is the reduction in CPU usage when accessing the RAM. This is because the CPU can access two memory modules simultaneously, allowing for faster and more efficient data transfer.

It’s worth noting that in order to take full advantage of dual-channel memory, both memory modules must be identical in terms of their capacity, speed, and timings.

It’s important to note that the device must be rebooted after installing or replacing any memory modules.


In conclusion, the HP EliteBook 840 G3 is compatible with DDR4-2133 SDRAM memory modules and can support up to 32GB of RAM. Depending on your needs and usage habits, 8GB RAM may be enough for basic tasks while 16GB or even 32GB will be better suited for more intensive applications such as video editing or complex web browsing.

Moreover, a dual channel memory configuration is recommended in order to take full advantage of the available RAM capacity.
