RAM Memory: How Much Do You Really Need and How to Upgrade It
The complete guide to choosing and upgrading your computer's memory
📋 CONTENTS
What is RAM and why is it so important?
The RAM (random access memory) is like your computer desk. The bigger the desk, the more things you can have open and working on at the same time. If you have a small desk, you have to constantly take things out and put them in, which slows you down.
In simple words: RAM temporarily holds everything you use while you're working on your computer – programs, web pages, files you're editing. When you turn off your computer, all of that is lost. That's why it's different from a hard drive, which holds your files permanently.
How much RAM do you need?
The amount of memory you need depends on how you use your computer. Let's take a closer look:
For whom? Basic use
• Internet browsing
• Email and social networks
• Text editing
• Simple office tasks
Note: 4GB is not enough these days. Prefer at least 8GB.
For whom? Average usage
• Multiple pages open at the same time
• Photo editing
• Light games
• Video streaming
• Multiple programs open
The best choice for most users!
For whom? Professional use
• Video editing
• Graphic design
• Demanding games
• Programming
• Virtual machines
For you who want maximum performance!
💡 Tip: If you're not sure how much memory you need, 16GB is the best option for most users in 2025. It's enough for almost anything and isn't overly expensive.
Types of RAM: What you need to know
DDR4 vs DDR5: Which one to choose?
RAM comes in different "generations" and each new generation is faster and more efficient than the previous one.
| Feature | DDR4 | DDR5 |
|---|---|---|
| Released | 2014 | 2021 |
| Speed | Good (2133-3200 MHz) | Very good (4800-6400 MHz) |
| Price | Economic | More accurate |
| Availability | Very big | It is increasing |
| Energy consumption | Normal | Less |
Which one should I choose?
• DDR4: An excellent choice for economy and compatibility. If you have a computer from the last 5-8 years, it probably supports DDR4.
• DDR5: A choice for the future. If you're buying a new computer now, think seriously. It's the new generation and will be the standard for years to come.
Memory Speed: Does it Matter?
Memory speed is measured in MHz (MegaHertz). Simply put, it shows how fast the memory can transfer data. For example:
- 2666MHz: Basic speed, good for everyday use
- 3200MHz: Very good speed, the most popular choice
- 3600 MHz and above: For demanding users who want maximum performance
⚠️ Attention: Your computer has a limit on the memory speed it supports. If you install faster memory than it supports, it will run at the maximum speed the computer can handle, not at its own speed.
Latency: The hidden secret of performance
What does CL mean?
"CL" stands for "Column Access Strobe Latency" but you don't need to remember it! Just know:
• CL14-CL16: Very good response (more accurate)
• CL18: Good response (the most common)
• CL20 and above: Normal response (more economical)
The truth: For the average user, the difference between CL16 and CL18 is minimal and you won't notice it in everyday use. Unless you're a hardcore gamer or a professional, don't worry too much about it.
Compatibility: How to make sure it will work
Step 1: What type of memory does your computer accept?
Before you buy memory, you need to find out what your computer supports. There are two main ways:
1. Press the keys simultaneously Windows + R
2. Write msinfo32 and press Enter
3. Look to the left for "System Information"
4. You will see what memory you have and information about your system
If you know your computer model (e.g. "Dell Inspiron 15 3000"), search for:
"Dell Inspiron 15 3000 RAM upgrade"
You will find information about what memory it accepts and how much you can put in maximum.
Step 2: How many ports do you have available?
Most computers have 2 or 4 slots for RAM. If you have:
- 2 ports: It's better to put 2 identical memory sticks (e.g. 2x8GB to make 16GB total)
- 4 ports: You can add more memory gradually
💡 Expert advice: Memory sticks work best in "pairs". If you want 16GB, choose 2 sticks of 8GB rather than 1 stick of 16GB. This is called "Dual Channel" and gives better performance.
Step 3: Laptop or Desktop?
Memory for laptops and desktops comes in different sizes:
⚠️ Important: You can't put memory for a desktop computer in a laptop or vice versa. They just don't fit!
How to upgrade RAM: Step by step
Preparation
Before you start, you will need:
• New RAM (compatible with your computer)
• A small screwdriver (usually cross-head)
• 15-30 minutes of free time
• A clean workspace
For Desktop Computer
1. Turn off the computer and unplug the power cord.
Wait 2-3 minutes for the power to completely go out.
2. Open the side lid of the box
It is usually unscrewed with 2-3 screws on the back. Some boxes have a quick-opening mechanism.
3. Locate the memory ports
They are vertical slots near the processor (the square one with the big fan). The memories are thin rods with chips on them.
4. Remove the old memory (if necessary)
Press outward on the clips at the ends of the memory. The memory will pop up slightly.
5. Install the new memory
Align the notch in the memory with the bump in the port. Press evenly on both ends until you hear a "click" and the clips close automatically.
💡 Tip: Before touching the memory or anything inside the computer, touch something metal (e.g. the faucet) to discharge static electricity from your body.
For Laptop
The process is a little more complicated and varies from model to model:
1. Turn off the laptop and remove the battery (if applicable)
Many new models have a non-removable battery. In this case, just make sure it's turned off.
2. Unscrew the bottom part
Some models have a small cover for the memory, others require you to remove the entire bottom cover.
3. Find the memories
It is usually under a protective sheet or near the fan.
4. Remove the old memory
Laptop memory sticks are horizontal. Push out the clips on the sides and the memory will rise to a 45-degree angle.
5. Place the new one
Insert the new memory at a 45-degree angle and press it down until the clips close.
⚠️ Attention for laptops: Some models, especially very thin ones, have the memory stuck and cannot be changed. Search online for your model before opening the laptop!
What do I do after installation?
1. Turn off the computer and turn it on.
The computer will automatically recognize the new memory.
2. Check if it was recognized
• Windows: Right-click on the "This PC" icon → Properties. You will see there how much memory you have in total.
• Mac: Go to Apple menu → About This Mac.
💡 If the memory was not recognized:
• Shut down the computer and make sure the memory is properly seated.
• Try a different port
• Make sure it is compatible with your computer
Frequently asked questions and solutions
Can I mix different memories?
The short answer: Yes, but it is not recommended.
For what reason? You can mix memory of different capacities (e.g. 8GB with 4GB), but the computer will run at the speed of the slower memory. For best results, use identical memory (same capacity, speed, and manufacturer).
Does more memory make the computer faster?
It depends! If your computer was running low on memory and was "choking", then yes, you will see a big improvement. However, if you already had enough for your use, the extra memory won't make a difference.
How to know if you need more memory:
• The computer is slow when you have many programs open
• You hear the hard drive working constantly
• Programs "crash" frequently
• It takes a long time to open new programs
Are DDR4 and DDR5 compatible with each other?
No! They are completely different and cannot be used on the same computer. They are shaped differently and do not fit into the same ports.
Do I need to update anything in Windows after the change?
No! Windows automatically recognizes the new memory and uses it immediately. You don't need to do anything.
Can I put 32GB if the computer supports 16GB?
No, unfortunately. Every computer has a maximum amount of memory it supports. If you try to put more in, it will either not work at all, or it will only recognize as much as it supports.
Can memory deteriorate?
Yes, but it's rare. RAM is very reliable and usually lasts as long as the computer. Signs of a problem:
- Frequent blue screens (Blue Screen)
- Programs that close abruptly
- The computer restarts by itself
- Strange graphics on the screen
Shopping Tips: How to Get the Best Deal
1. Manufacturer selection
The most well-known and reliable memory manufacturers are:
- Corsair: Very popular, wide variety
- kingston: Reliable and economical
- Crucial: Excellent value for money

✓ Speed (e.g. 3200 MHz)
✓ Warranty (at least 2 years)
✓ Compatibility with your computer
4. When is the best time to buy?
Prices for memories fluctuate. In general, the best periods are:
- Black Friday / Cyber Monday
- School offer period (September)
- When a new generation comes out (the old ones get cheaper)
Myths and truths about RAM
Myth 1: "The more memory, the better"
Truth: There's a point after which additional memory doesn't add anything. If you're not using all the memory you have, adding more won't make a difference.
Myth 2: "Memory with lights is faster"
Truth: The RGB lights are for display purposes only. They do not affect speed or performance in any way.
Myth 3: "I have to install memory from the same manufacturer"
Truth: It is not necessary, but it is recommended for optimal compatibility. The most important thing is that they have the same specifications (speed, timings).
Myth 4: "RAM degrades quickly"
Truth: RAM is one of the most reliable components in a computer. You are more likely to replace your computer than have the memory fail.
Myth 5: "The computer always uses all the memory"
Truth: Windows keeps some memory "free" for future use. If you see that 50% of your memory is being used, it doesn't mean that Windows needs more.
Alternative solutions if you can't upgrade
Sometimes upgrading memory is not possible (e.g. on very old computers or laptops with stuck memory). Here's what you can do:
1. Close programs you are not using
Many programs run in the background without you knowing. Click Ctrl + Shift + Esc to see which programs are consuming memory and close the ones you don't need.
2. Use lighter programs
Instead of Chrome (which eats up a lot of memory), try Firefox or Edge. Instead of Photoshop, try GIMP or Paint.NET.
3. Disable graphic effects
Windows has many visual effects that consume memory. You can disable them for better performance.
4. Clean the computer
Uninstall programs you don't use and delete temporary files. This indirectly helps memory.
💡 Quick improvement: If your computer is still very slow even after upgrading the memory, the problem may be your hard drive. Upgrading to SSD makes a huge difference in speed!
Conclusion
Upgrading your RAM is one of the simplest and most effective improvements you can make to your computer. With a little money and a little time, you can breathe new life into an old computer.
