Determining the type of RAM that can be installed – selecting the best part – ordering – tools needed – disassembling a laptop – replacing RAM – assembling – commissioning – software inspection
Is the laptop slowing down? Do I have to wait a long time for a program to start? If you open 3-4 windows in the browser, will the machine slow down?
In 2021, a laptop used for browsing, movie editing, word processing, and spreadsheet management will have roughly 8 GB of expected memory size. This hardware device is the fastest memory in your computer, so words don’t matter how much of it you have.
If there is not enough, the computer will start writing data from this short-term memory to the long-term memory (in most cases to HDD, hard disk, or winchester), which, however, is much slower than it would be for the program to run. Therefore, you can feel a significant slowdown in such cases.
1. Make sure you have a RAM problem
If you are using windows 7, right-click on the free desktop area and select the “Gadgets” tab from the shortcut menu that appears. Select “Processor Monitor” from the applets that appear. Click on it and a small speedometer application will appear on the desktop.
The clock on the left shows the performance of the processor, the other the amount of RAM memory. Neither is good if it shows too high a value, but we are now interested in memory.
If you only look at the value when the machine starts, it can be deceptive. Record the value shown once an hour on a day spent working. Do not close the programs you are currently using, just put them down with the line at the top right. So run an explorer, a browser with a few windows, possibly a music player, a word and an excel.
Look at your notes at the end of the nep. If the prescribed values are between 80-90%, the RAM may be tight, you may want to consider replacing it.
2. Look for a description of your laptop
and check what kind of RAM is prescribed there and how many pieces your machine can handle. You will find something like this.
RAM: 4 GB, up to 2 × 8 GB DDR3 SO-DIMM RAM.
It might include something like 1333 MHz, or 1600 MHz, something like that.
In a laptop, RAM is sure to be an SO-DIMM.
The socket, if older than the noti, will be DDR3, if newer, it will be DDR4.
You may want to summarize this data in a small table, such as:
clock:… (if you enter the factory description clock)
Memory speed:… (typically CL9, CL 11, or, higher numbers, depending on how old the machine is and how expensive the memory is).
3. Disassemble the laptop
You will need a set of mechanic screwdrivers that includes small straight and cross screwdrivers. It doesn’t hurt to have some special bitheads or screwdrivers in reserve, either (torx or hex), but they’re usually not needed. Have a camera or cell phone on hand.
Disassembly will void the warranty, so only start if the warranty has expired or the RAM problem is so severe that it needs to be fixed.
Shut down the laptop properly using the Stop button.
Once this is done, unplug the charging cable from the machine.
Fold down the notebook screen, and then turn the computer over.
Remove the notebook battery. To do this, they usually place 2 simple mechanical latches around the battery, which you need to pull off or unscrew 1-2 screws, but rather the first one.
Study the back of the machine. The back cover (part of the back cover) of these machines usually comes down at once, just a few tiny screws need to be unscrewed. You have to have this screw covered by the removed battery so far, so check it out there too.
If you unscrewed the second or subsequent screws, make sure it is the same screw as the previous ones (usually yes). If there is a discrepancy, write down which screw is where, because if you end up with a lot of small screws, assembly will be difficult.
So if you unscrewed the screw holding the back cover, move the parts of the back cover a little. Whichever moves will come down. Move it carefully and watch where it moves more easily. Do not tighten, they are designed so that they do not have to be snapped out, but slid out of place, the unscrewed screw prevents this slipping.
If the back cover comes down, a part of the laptop will be revealed to you and you will also notice the RAM. These are small inserts about 3 cm x 7 centimeters.
If you find it, take a photo.
If it has a caption, take a photo.
Check how much installation space you have (usually two).
Notice how the RAM is located, how far it is pushed into the socket. There is only one way to put it back, but it is important that it is pushed all the way back into place.
The RAM will be held sideways by two small metals, these should be gently removed from the RAM. As this happens, the RAM is released and can be gently moved out of its socket.
Be careful not to touch the RAM with a screwdriver or any metallic (conductive) object when placing it on the non-conductive surface.
Many times there are stickers on the RAM with all sorts of part numbers. Take photos to read on both sides. When you’re done, the RAM can go back into place. You set the RAM to fit according to the socket.
You then push the RAM into place with the contact surface, as you saw it before the exception. If necessary, check the photo.
When the RAM is in place, gently push the chip down so that the two metal on the side snaps into place to secure the RAM.
Then put the removed cover back on and secure it with a screw. Make sure that screws do not fall into the inside of the machine. At a minimum, it would be uncomfortable to take out a small screw, but it can also cause a serious mistake.
You put the battery back, you lock it with the lock. You connect the charging cable and turn on the machine. If the machine starts up okay, you did everything right. If something goes wrong or you get an error message, the RAM is out of place, you need to go back to disassemble, and put the RAM in place. Usually the problem is that the RAM does not dare to be pushed into place properly.
Download the CPU-Z program here: https://www.cpuid.com/downloads/cpu-z/cpu-z_1.96-en.zip
Use of the program is free (legally).
Extract the ZIP program to a separate folder and run the cpuz_x32 or cpuz_x64 file in the folder.
After a little thought, the program opens an out window. Switch to the “Memory” tab and also check there what the latency of your RAM is. The CAS # Latency (CL) entry should be viewed.
4. You need to decide how much RAM you want
It basically depends on what you want to use the machine for. For general use in 2021, I recommend 8GB, for more serious use (games, videos, photographic works) at least 16GB, but rather more.
Check the factory documentation to see what the upper limit is in RAM. It’s not worth going over because this laptop won’t be able to handle it.
5. You need to decide what to do with your existing RAM
You can see how much RAM is in the machine. If it’s 2GB, you won’t know what to do with it, after the replacement you’ll at most put it in reserve if anything happens to the new module.
If you have 4GB in the machine, you can choose to sell it or put it away (if you don’t sell it now, it will be worth less and less later).
I suggest you don’t sell it and put it in reserve, but add RAM with the same parameters.
Type the part number you see on the RAM into your internet browser. You will find the factory description of the RAM. From this you can see the exact type and technical parameters of the RAM. Make a note of yourself in the way you learned earlier.
clock:… (if you enter the factory description clock)
Memory speed:… (typically CL9, CL 11, or, higher numbers)
number of modules:… (eg 8)
Check www.arukereso.hu and some major IT specialist shops (www.pcx.hu www.rufusz.hu etc.) to see if the same type is available.
If so, you have a case won, but check that the type found is really the same (a discrepancy in the part number usually means a slightly different technical parameter).
If the existing module is no longer manufactured, look for a module that is identical to the existing one in all its parameters, if possible.
This is important because if you find RAM with the same parameters, chances are they can work together and also work in so-called “dual chanel” mode, which will make your machine even faster.
You can set the filter parameters one by one in the product finders of the best specialty stores. These should be the parameters of the existing module. So you set what you are looking for
SO-DIMM module (these will be the laptop modules then
narrow it down to DDR3 (if you have it, or DDR4 if you have it)
you narrow it down to memory size, e.g. 4 GB
you narrow it down to 1600 MHz or what the existing one knows.
You can’t narrow it down to memory latency (CL9, CL11) and modules at most stores, but by the time you get here, you’ll have quite a few hits anyway.
The delay should also be the same as the delay of the existing module and, if possible, the number of units on the RAM module should be the same (eg 8).
This will give you the best chance that the dual chanel will work for you as well.
If you can still choose from several products, check out the warranty. For these modules, the more expensive ones have a lifetime warranty or a 1 + 4 year warranty.
Honestly, if your laptop needs to be expanded, it is already 3 years old, now the cheaper new module is also given a 5 year warranty, so you will be fine until the age of 8 years. That seems enough. Of course, if you want the best, I’ll buy a Kingston lifetime warranty RAM (only two times more expensive than its cheaper counterparts).
Compare again the factory specifications, the properties of the existing memory, and order the intended properties of the selected RAM, if you find everything to be right (match!), You can go for the order.
6. Install a new RAM module
Handle the new RAM module with care with care, do not touch metal.
Disassemble the laptop as described in step 3.
You align the new RAM module in the socket and gently push it into place, so you push it into the receiving part.
Once you have this, gently push the RAM module down so that the side mounting metal tabs snap into place and secure the RAM.
You assemble the machine (back cover -> battery -> charger).
7. Testing, RAM module
You turn on the machine and check that everything is working.
