How much computer RAM do I need? You must have wondered this after hearing the suggestion of increasing computer RAM to increase system performance. However, increasing the computer RAM is not always the answer, and incrementing it is not always that simple.

This question usually pops up in your mind when you experience unresponsive programs and applications, and higher load times. The worst issue users face is when the display lags while using the device. 

The reason behind the how much computer RAM do I need question is that we keep hearing it way too often. From a technical point of view, it is true to some extent. However, other factors such as storage and compatible power supply also contribute to increasing computer response time.

Yes, but mainly for the user-intensive and power-hungry tasks increasing computer RAM can make a change in performance. This process involves understanding the type of computer RAM and how to choose computer RAM sticks for your PC

The other main aspect of increasing the computer RAM is to know the RAM compatibility of your PC, laptop, or tablet. There are subtle yet significant differences between DDR4 vs. DDR5 RAMs that set them apart, and knowing them is necessary. 

Multitasking in today’s daily life requires many opened tabs, and users switch through them faster than the blink of an eye. The lag in the switch causes many to think about how much computer RAM is needed to fix the problem, especially during gaming or other resource-intensive operations. 

We know gamers also search for the best RAM for gaming; we will address that problem. What better way to enjoy gaming while making your computer fast for daily routine tasks? Let’s get down to it, but first, the basics.

What Is a Computer RAM?

Two RAM sticks of DDR4 RAM

Random Access Memory is the full form of RAM in a computer. Computer RAM is the primary memory used along with cache memory. The primary function of computer RAM is to store the data actively required by the CPU and processor with the help of the cache memory. Like cache, RAM is volatile and does not store data after the power is turned off. It is fast because it is temporary, and the CPU has direct access to it. The CPU can read and write data directly on the computer RAM and retrieve it faster than it would from a storage device. 

Form Factor

Form factor is a term used to describe the physical form of computer RAM and how it differs between desktops and laptops. RAM modules come in different DIMMs which stands for Dual In-line Memory Modules. 

A DIMM (Dual In-line Memory Module) contains DRAM chips. It’s a Printed Circuit Board (PCB) with multiple RAM chips mounted on it. DIMMs are designed to be installed in the memory slots on a computer’s motherboard

These are the types of DIMMs;

  • The most popular form of RAM module sold for personal computers is UDIMM, which stands for Unbuffered and/or Unregistered. Simply writing “DIMM” on a RAM product listing indicates that it is most likely UDIMM.
  • Since SO-DIMM is required for laptops, it ranks as the second most common form of computer RAM. A “small outline,” or SO, is essentially a smaller DIMM. As mentioned before, SO-DIMM can also be Unbuffered; this is the type of computer RAM typically found in laptops.
  • MicroDIMM is similar to SO-DIMM but even more compact. Although these RAM modules aren’t as widespread as the other two, they might be used by tablets or some smaller laptops.

DDR

Modern-day RAM is identified as DDR, which stands for “double data rate.” It is a successor to DRAM, which stands for dynamic random access memory. Then these DRAMs were upgraded to SDRAM with better circuit designs and a clock signal to sync with other parts of the system, hence the name Synchronized Dynamic Random Access Memory. 

The innovation of DDR was to double the amount of data bandwidth to perform better. Think of it like widening a single road in double to increase the traffic flow. DDR comes in generations denoted by the number after it, like DDR2, DDR3, DDR4, and now the current is DDR5. DDR6 is soon expected to come out and is in the development stage. However, sometimes users confuse GDDR6 and GDDR6X GPU VRAM with DDR6 computer RAM sticks.

Capacity

More RAM means better performance; of course, 8GB RAM of a computer will perform better than 4GB of computer RAM. As for gaming, the specifications mention the capacity required. A normal requirement is usually 4GB for daily tasks of web browsing or documentation, but this is the bare minimum, and you will not get much out of it. That is why 8GB minimum is recommended and 16GB for casual gamers.

Moreover, buying additional RAM for a 32-bit processor is a waste of money as it can only make use of computer RAM of up to 4 GB. The next generation of 64-bit processors can theoretically support 4 petabytes of memory. This is on paper only, but in reality, it can support computer RAM between 32 GB and 256 GB. To know what capacity your motherboard can handle, you have to check what motherboard do I have from the specs manual. 

Speed

This is the aspect or feature of the computer RAM that should excite and entice gamers and PC users. People do not think how much computer RAM speed I need because it is a bit of a complex concept. The two features that define the speed are frequency and timing.

✅ Frequency is referred to as speed in common terms, which is understood. It means the read/write cycle of RAM sticks. Reading and writing cycles happen constantly in memory with the currently loaded data. The frequency number tells you how many times per second the memory goes through that cycle. You will usually see the numbers after the name, like DDR4-3200, where 4 represents the generation, and 3200 refers to the 3200MHz frequency of 3.2 billion read and write cycles per second. 

Higher frequencies generally mean better performance, but the performance also depends on CPUs and motherboards. Not every motherboard supports every frequency and may not work effectively with a higher one. Also, higher frequencies are more pricier.

✅ You must have heard of Column Access Strobe or CAS latency, which is the technical term for speed in computer RAM. To understand it more easily, consider it as the unit of measurement of the time it takes to execute the command received from the CPU. The CAS value is nominated in numbers like 16-18-22, and the lower number is better. 

However, the difference between the numbers is not going to make that much of a difference because of the modern auto-detect settings and memory controllers. These differences are much required and difference-makers in the gaming perspective.

Channels

Remember we talked about widening the road before? The channels are the road on which the data or commands travel from the CPU to the computer RAM. The more the channel, the more the transfer. Even if you have the fastest CPU and exceptional RAM, if they are on a single channel, the same channel becomes a chokepoint for them and cripples the performance. CPUs are the components that support channels, and most current-gen CPUs support two to four memory channels. That’s why it’s also important to ask the question, what processor do I have before upgrading your system with the best DDR5 RAM choice suitable for gaming.

computer RAM slots on the motherboard physically support the CPU. To acquire the best gaming memory performance, you will need to use multiple channels with multiple RAM sticks. This means that to use 16 GB of computer RAM, you will require two 8GB RAM sticks. The limitation with this approach can be that if you have two RAM slots, then you will need to change both the RAM sticks to upgrade. It is best to use RAM sticks that have matching frequency and timing. The out-of-sync RAM or different capacity scales back the performance.

How Much RAM Capacity Do You Require For a Desktop?

For most daily tasks, casual gaming, and future-proofing, 16GB of RAM is enough. More details of desktop memory are mentioned below;

  • 4GB: Some tablets and low-end Chromebooks include 4GB of RAM, but they are only worthwhile purchases if you have a very tight budget.
  • 8GB: Usually found pre-installed on budget laptops. This works well for simple Windows games at lower settings, but the steam quickly runs out.
  • 16GB: Great for gaming, especially if it’s fast RAM, and great for Windows and MacOS PCs as well, though certain titles still require more.
  • 32GB: This is the ideal amount for experts and sophisticated players. Although the price is still reasonable, playing any game is sufficient.
  • 48GB: If 32GB of RAM is insufficient and 64GB is superfluous, you may be able to save some money by using non-binary memory kits.
  • 64GB and above: This is only for enthusiasts and specially designed workstations. Professional A/V editors, engineers, and others who are interested need to scale more if necessary.

Side Note: RAMs offering more 64 GBs of capacity are mostly used in server systems. These RAMs have a similar form factors as Desktop memory and are referred to as server memory.

How Much Computer RAM For Laptop?

Laptop RAM

As the demands of modern applications increase, the need for more computer RAM becomes paramount. Now, laptops come with 8GB pre-installed RAM and options for 16GB. Premium branded laptops are packing a RAM punch of 32GB to fulfill today’s demands. So, choose your Laptop memory accordingly.

We have already mentioned the use case and capacity requirements in the above section for desktops. It is the same in laptops, and a general rule of three capacity variants;

  • 8GB
  • 16GB
  • 32GB

Going beyond these capacity caps is advised only if you have to perform certain tasks, such as editing high-quality pictures, vast volumes of videos, or playing really demanding AAA games. Increasing just the computer RAM will not bring back ROI instead, other aspects like CPU and GPU are equally important. 

Many laptop users do not consider the device for such tasks, but if you are, then buying enough RAM is important. Moreover, upgrading the RAM of a computer is easier than upgrading a laptop (in some recent models, it is almost impossible). So, making a smart decision is compulsory. 

Difference Between Laptop and Desktop RAM

How Much RAM Does Tablet Support?

Tablets are not supposed to do RAM-intensive tasks like smartphones, hence they do not come with more. However, the evolution of apps and software in the tabs sphere has pushed them to accommodate more RAM. These innovations have widened the range from 2 to 16GB of computer RAM because they also have to balance the processor speed and battery life.

Nowadays, tablets have 8 and 16GB of RAM, but some budget models also come with 4GB of RAM. If you are eyeing 4GB RAM for your tablet, then prepare to have patience while multitasking. Other than that, 8GB is enough for almost any kind of use, but almost. If you want to go all out, then 16GB is the deal, but we do not recommend it because you cannot mostly perform tasks on tabs that require that much RAM.

Difference Between Tablet and Laptop RAM

Tablets are compact and have less space than a laptop. Therefore, neither ram is compatible with the other.  The following section will highlight these differences in more detail.

1. Form Factor

Laptop RAM:

  • SO-DIMM (Small Outline Dual Inline Memory Module)
  • Size: About 67.6 mm (2.66 inches)

Tablet RAM:

  • Soldered Chips or LPDDR (Low Power Double Data Rate) Modules
  • Directly soldered onto the motherboard, not replaceable

2. Capacity

Laptop RAM:

  • Typically, higher capacities (4GB to 64GB or more)

  • Uses SO-DIMM modules that can be replaced or upgraded
  • Requires opening the laptop chassis for installation

Tablet RAM:

  • Integrated and soldered onto the motherboard
  • Not user-replaceable or upgradable

5. Heat Dissipation

Laptop RAM:

  • Designed to handle more heat with better cooling solutions
  • Larger chassis allows for better heat dissipation

Tablet RAM:

  • Designed for minimal heat generation
  • Limited cooling due to compact and sealed design

6. Power Consumption

Laptop RAM:

  • Higher power consumption compared to tablet RAM
  • Requires more energy for higher performance

Tablet RAM:

  • Lower power consumption for longer battery life
  • Optimized for energy efficiency

Laptop RAM (SO-DIMM) offers higher capacities, better performance, and upgradability but consumes more power and generates more heat. Tablet RAM is integrated and optimized for power efficiency, compact design, and lower heat generation but is not upgradable and has lower capacity.

How Much RAM Do I Need For Gaming?

This is a really interesting and frequently asked question, too. The DDR4 was cutting it for quite some time until the DDR5 arrived. It does not differ in terms of capacity but rather in data transfer rate, bandwidth, and power consumption. The capacity requirement will still be the same, and with the best DDR4 RAM, it won’t make much of a difference.

If you are starting from scratch to build a gaming PC, 16GB is a good budget option. If you want to experience a legit gaming experience, we recommend opting for 32GB. Before, 8GB was able to pull the AAA games, but now they demand as much as 32GB. 

16GB of RAM can also be enough for many games like Cyberpunk 2077, Microsoft Flight Simulator, and Red Dead Redemption 2. These games almost consume the RAM, leaving little memory for the background applications. If you need to run applications like OBS Studio for streaming along with a web browser, then 32 GB is a must. Feeling more generous than 48GB with a non-binary kit is also an option.
