View in BIOS
For this method, you will need to reboot the device. While the device is booting, you need to enter the BIOS using the keyboard button. It can be Esc, F1 or another key depending on the laptop or desktop PC model.
You can quickly understand how much RAM is in the device. This information is located in the “Main” section.
How to understand how much RAM (RAM, RAM) on your computer. 5 ways
When buying a used PC or laptop, you need to understand how much RAM is installed in it. This information is also useful if the user sees that the computer has begun to slow down. A detailed guide will tell you how to see the amount of RAM in the device, and what to do if there is not enough RAM.
An efficient and fast program. There is not only a paid, but also a slightly stripped-down free version.
How to see how much RAM is in a computer or laptop:
- Run the software and select “Motherboard”.
- To find data on the volume and percentage of occupied space, go to “Memory”.
- If you need more, the “SPD” tab will do. Here you can find information about the type and manufacturer, as well as the frequency, voltage and timings.
You can also see how much RAM is in a PC with this classic operating system tool. In the “Manager” you need to find the “Performance” section, and then. “Memory”. All information will be displayed in the same window.
How to find out how much RAM is on a computer
This can be done using special software, in BIOS and classic Windows tools.
What is RAM
This device remembers all data exchanged with other components. RAM is volatile. It stores both its own code and all data processed by the central processing unit (CPU), including intermediate.
- Open a line on behalf of the admin and enter wmic memorychip get Manufacturer, Capacity, PartNumber, Speed, DeviceLocator
- In the column “Capacity” you can see the number of MB.
How the amount of RAM affects PC performance
Since the RAM contains all the data that the processor must accept, its amount directly affects the speed of information processing by the components. The volume and frequency depends on how stable the PC or laptop will work. These characteristics also affect the performance of the system when using multiple heavy programs at the same time.
The easiest way to see how much RAM is on your computer is to open the computer properties window. This can be done in several ways. For example, if your work computer has an icon “My Computer” (just an icon, not a shortcut), then you can click on it and select “Properties”.
You can also open a window with computer properties through the “Control Panel”. To do this, open the “Control Panel” and go to the “System and Security. System”.
Another option is the Windows-Pause / Break key combination. Just press this key combination in any window, and the window we need will open in front of you.
After you have opened the window with the properties of the computer, pay attention to the item “Installed memory (RAM)”.
The amount of your RAM will be indicated here.
How to see how much RAM is on your computer
Random access memory is one of the main components of any computer. The amount of programs with which the user can work simultaneously depends on the amount of RAM. The more memory, the more programs you can run without affecting your computer’s performance.
In addition, some programs and computer games require a certain amount of memory for normal operation. Therefore, inexperienced users very often ask how to see how much RAM is on a computer. We will consider this issue within the framework of this article.
If you have Windows 8 or Windows 10, then you can see how much RAM is on your computer using the “Task Manager”. To do this, open the “Task Manager” (for example, using the CTRL-Shift-Esc key combination), go to the “Performance” tab and open the “Memory” section there.
Here, in the upper right corner of the window, it will be indicated how much RAM is installed on your computer.
You can also see how much RAM is on the computer using special programs designed to view the characteristics of the computer.
For example, you can use the CPU-Z program. Run this program on your computer and go to the “Memory” section.
This tab will indicate how much RAM on the computer. Also here you can see other characteristics of RAM.
If the operating system is not yet installed on your computer or it does not start, then you can see the amount of RAM using the BIOS. Go to BIOS and examine its contents. One of the BIOS sections should contain information about the computer.
Usually, the processor model, its clock frequency and the amount of RAM are indicated there.
How to check RAM in Android device.
How to check RAM in Android using an app
Random access memory (RAM, RAM)
Android devices have memory: internal (ROM, ROM), RAM (RAM, RAM) and removable memory cards (SD or microSD).
Internal memory is used to store system and user data.
Random access memory (RAM). temporary device memory that stores running programs. The larger the amount of RAM, the more applications can be run at the same time, and the “heavier” applications (eg games) you can run.
By using a memory card, you can increase the size of the user memory. That is, you can use it as additional memory to store photos, music, videos, and more. In some versions of Android, you can save applications to external memory.
Often people ask themselves where to look at the RAM in Android devices and how to check its real size
Earlier, back in Android 4 and Android 5, users most often looked for the amount of RAM in the settings, in the “Memory” section, but in this version this is not true, this section only displays the size of the built-in memory and SD memory card.
The size of the RAM, however, you need to look in “All settings”, in the section “Applications”.
In the first section of these settings, at the bottom, there will be the values of the built-in memory (free and busy), and if you scroll to the right, you will see “Running applications”. At the bottom of this section it is written how much RAM is busy and how much free RAM, if you add up these numbers, you get the size of your RAM. If this amount is about 1GB (1000MB), then this is considered 1GB, if over 1GB (1000MB), then this is a 2GB version of RAM.
In newer versions of Android. 7.1, 8.1 and 9.0, the RAM is already shown more clearly. Some set-top boxes have different types of settings and therefore it is difficult to know where to look.
Go to the Android prefix settings, on a white background, scroll down and you will immediately see the amount of RAM and internal.
Unfortunately, there are firmwares in which the information in the settings does not correspond to reality, therefore there are application programs that show the real amount of RAM.
One of the best applications, in our opinion, that actually measures RAM is “Fill RAM memory”, also called Real RAM optimizer or “RAM filler”.
First, you need to download and install this application, you can download it from Playmarket.
Install it and click “Open”. To check the RAM, you need to click on the “Fill all memory” button, and then follow the digital value that increases. When the RAM is full, the program will crash automatically, so review the value until the end, before departure.
If the program crashed with a value of 400-500MB, then the RAM is 1GB, if 1200-1400MB, then 2GB. This does not mean that the RAM is truncated, which means that the rest of the space is system memory, so the program cannot fill it, and the indicator does not reach its integer value (1000MB, 2000MB, 3000MB, 4000MB).
Now you know how to properly check the RAM on an Android set-top box or other Android device!
How to increase storage on iPhone using cloud storage
The easiest and most widely available way to expand your phone’s memory is through clouds. Already in the settings in the “iPhone Storage” tab, the developers recommend, to save memory, enable automatic uploading of photos and videos to the secure iCloud storage installed on each iPhone by default.

How to Boost Your Phone’s Memory with Junk Cleaner
Another surefire way to boost your memory is to get rid of the junk on your phone. This includes the following:
- unused applications;
- unnecessary and transferred to external media photo and video files, music;
- data from Safari and other browsers;
- cached data of installed instant messengers;
- unnecessary iCloud emails;
- SMS messages, etc.
Also, for quick and effective cleaning of iPhone from debris, it is recommended to install one of the profile applications: Smart Cleaner, Battery Doctor, PhoneClean, Gemini Photos or others.
Note! Photos and videos take up the lion’s share of all iPhone memory. Therefore, it is so important to regularly clear your library, including the “Recently Deleted” folder, of bad frames, duplicates and screenshots.
How to increase storage on iPhone using an external hard drive
An external hard drive is a portable storage device and another way to expand the memory of a gadget. An example of such media is SanDisk, with capacities ranging from 16GB to 256GB. The disk comes with MicroSD, so the amount of memory can always be changed to any other by purchasing a memory card of the required capacity.
Note! This external storage medium acts as an intermediary, transferring files from iPhone to computer, and vice versa. Has a power button, wireless indicator and USB input. Connects to an iPhone via Wi-Fi without using wires or cables, and to a computer via a USB connector.
Such an external hard drive will allow you to stream from 3 devices at the same time. The firmware is used to configure the disk. The cost of the device varies from 5000 rubles. up to 30 thousand rubles.

How to find out the RAM of your computer? Easily!
Hello everyone! It is a long time since I wrote about computers, but all because I found a new job and I have no time at all. Today I will tell you how to find out the computer’s RAM.
Computer performance depends on many factors, including the amount of RAM. This article will show you how to independently find out the RAM of your computer.
How to find out the RAM of your computer in several ways, which are described below.
Further, after reading the article, you can figure out how to find out the RAM of a computer or laptop. We act and repeat after me!
- Open the context menu of the shortcut “My Computer” (right-click on it once). Next select “Properties”.
As a result, a window will appear where the size of the available RAM, the type of operating system (for example, 32-bit), etc. will be indicated.
- An alternative method is to go through the “Start”.
In the window that appears, enter manually msinfo32 and press Enter.
- Another way, which is based on a combination of function keys.
- Click “Win R” and in the window that opens, enter dxdiag.
- A new window will appear. Pay attention to the line “Memory”. The physical amount of computer memory will be indicated there.
- All methods describe the free amount of Gigs on your PC.
But how you can find out exactly the RAM of your laptop or computer, to analyze its additional characteristics, read below.
I want to warn you right away that you cannot do without the use of third-party applications and utilities. One of these programs is Speccy. It allows you to access all the characteristics of the modules and boards that are currently connected to your PC.
The utility is free and available for download from the Internet.
Then click on the link to start the download.
After downloading the program, proceed with the installation. The utility is installed in standard ways, without much difficulty.
To check what kind of RAM is installed on your PC, do the following:
- Run the program.
- Open the “RAM” section.
And then just read the information you are interested in. Everything is described there in an accessible and understandable way. There are characteristics about the type of DDR, the number of channels, volume and frequency. You can also see how many percent of RAM is used at a given minute and many more useful characteristics. Based on these characteristics, you can decide whether you should increase your RAM or not.
And here is the most direct way how you can find out the RAM of your computer. If you understand all the hardware of the system, then:
- turn off the power supply of the system unit;
- remove the cover;
- pull out the modules with memory and read the characteristics you are interested in directly on them.
However, this method is only for experienced craftsmen and not for beginners.
On a note! Recently, if you missed, I told you how to disable sleep mode or how to disable the mouse on a laptop. And I also talked about how to reduce the brightness of the screen on a computer. Be sure to read and do not forget to leave comments on the articles.
That’s all for me! Now you surely know how to find out the computer’s RAM. Please write your wishes and comments under the article. I also advise you to subscribe to new blog articles and receive new ones directly to your mail. I wish all my readers great health and peace.!
The easiest way to find out the basic parameters of the RAM installed in the computer is to inspect the module of the already installed RAM. To do this, you must first turn off the computer’s power, then remove the cover and pull out the bracket (to remove it, you will need to loosen the clamps on both sides). It should have a sticker with key information about RAM.
Pros of visual inspection:
- No need to turn on the computer and download third-party applications;
- In addition to the main parameters of RAM, you can find out its exact model.
Cons of visual inspection:
- If the sticker from the RAM has been torn off, you will not be able to find out the information;
- Some modern RAM modules are not glued with stickers with information due to the presence of a cooling radiator on them;
- This method is not suitable for laptops, since removing the lid from them is a very laborious procedure.
Another convenient application for viewing information about the components installed on a computer is AIDA64. To find out information about the RAM through the program, you need to select the SPD item in the “Motherboard” tab. The application determines all the basic parameters of RAM.
How to find out what kind of RAM is installed in the computer
Increasing RAM is one of the easiest ways to speed up your computer if you have problems with reloading pages in the browser, slow minimizing and expanding applications and other symptoms of insufficient RAM. Installing additional RAM is a simple procedure that can be dealt with without calling the service.
However, it is required not only to install, but also to choose the right new modules for purchase. Random access memory differs in type, frequency and size. Before buying new RAM modules, you need to find out what kind of RAM is installed in the computer, choose the right one and purchase.
Through the BIOS or UEFI environment, you can determine the main parameters of the RAM installed in the computer. To do this, you need to press Del to go to the BIOS settings before starting the operating system, that is, immediately after turning on the computer. Next, you will have to act depending on the BIOS or UEFI version:
- If we are talking about older BIOS versions, you need to look for information about RAM in the Memory Information column, which is located in the Chipset tab. Please note: in different BIOS versions, the location of information about RAM may differ.
Advantages of determining RAM parameters using BIOS:
- You can get data even if Windows is not installed on the computer or is not loaded;
- If you need to check several RAM modules in a row for their detection by the system, this method is the fastest.
Disadvantages of obtaining information about RAM using BIOS:
- Since there are many BIOS versions, and most often they are not localized, it is difficult to find information about RAM among the mass of parameters;
- The old BIOS does not always display all the necessary information, and often only the amount of RAM is visible.
The Windows operating system has built-in utilities that allow you to find out the minimum information about the RAM. its used amount. That is, it will not work to determine the memory type and frequency with the utilities of the operating system.
There is another important limitation. Windows will only show the amount of memory used, not the total size of the installed memory. This aspect should be considered if the computer is running 32-bit Windows, which does not support more than 3 GB of RAM. That is, if the computer has more RAM installed, this will not be displayed in the diagnostic utilities, and the “extra” memory will not be used during operation.
There are several ways to find out the amount of RAM using Windows tools. The easiest way to do this is as follows:
- Right-click on the My Computer icon in File Explorer and select Properties. A window will open, where the amount of installed RAM will be indicated;
How to choose replacement RAM
Choosing RAM to install on your computer is pretty simple. Two cases are possible:
The computer already has RAM and its volume must be expanded by installing an additional module. In such a situation, it is advisable to purchase a bar, the volume of which corresponds to the one already installed in the computer. over, they should not differ in type and frequency;
Most often, users add RAM to the computer, and they need to determine what memory is currently installed.
- They go to the App Store, find an application for viewing the characteristics of a smartphone, install it. For example, the excellent AIDA64 app.
- Run the installed program and go to the “Memory” category. All the necessary data about the memory of the gadget is available here.
- The line “Total RAM” displays the amount of RAM, and in “Available”. the amount of unoccupied RAM.
Thus, you can see how much RAM is in the iPhone 7 and other models.
You can see the amount of RAM yourself through the AIDA64 application
How much RAM is in the iPhone 7 and other models
The amount of RAM, or random access memory, is the main characteristic of any device: laptop, phone, stationary computer. Therefore, when choosing such a technique, the question of its volume always arises. The cost of the device also depends on it. The article tells how much RAM is in the iPhone 7, its amount in other models and their modifications, as well as how to choose a smartphone yourself, how to find out how much RAM will be sufficient, what to pay special attention to when buying.
What affects the amount of RAM in the iPhone
Random access memory is needed not only for acquiring new information and storing it. Its effect on the basic processes of the iPhone depends on the quantity. Among those are:
- the speed at which the operating system is running. This directly determines the comfort of its use. When the capacity is small, freezes, slowdowns in the operation of the application and the operating system itself are likely;
- the speed of launching and running downloaded applications. The more programs are loaded, the more they will use RAM;
- the functioning of the downloaded applications in the background. When the gadget has enough RAM, there will be no problems with the background operation of the program. After closure, they will continue to operate in the same mode as during the main period of operation in direct use. When there is not enough RAM, one application will close when closed with another. This is done to free up space to complete the current task.
When you have enough RAM, your iPhone is very fast.
The amount of RAM in different iPhone models
Since the early days of iPhones, Apple has taken an incredible leap forward. To see this change in practice, you need to consider and compare several lines of gadgets, starting with model 5 and its modifications and ending with 10.
How to choose a model: a few tips
The lineup of iPhones presented with different amounts of RAM is simply impressive, as well as their cost. In addition, there is no inability to increase memory in the future, so before buying it is worth weighing the pros and cons.
The variety of iPhone models makes the choice a little difficult
A few words about the amount of RAM and capabilities:
- An iPhone with 32 GB of memory is suitable for those who need a gadget to make calls and use the Internet. With the help of specialized online services, you can listen to music. Holds a small amount of photos;
- 128 GB is the optimal amount. There is enough space for storing all the photos. It is possible to record games. To download and watch movies, you should choose a gadget with a lot of RAM;
- 256 GB is an option for those who do not want to think about the amount of available memory at all. Movies, games can be uploaded in any quantity, not to mention photos and video recording.
Note! These tips will help you make the right choice, especially since the price difference is significant. Why overpay for the latest model when you only need a smartphone to make calls and access the Internet.
iPhone 6 and its modifications
How much RAM is in the iPhone 6? The 6 and 6 Plus still have the same 1 GB. But in the next smartphones it is doubled, up to 2 GB, which is already much better. 2x more storage capacity. And the operating system works just fine and super fast. This is a really noticeable and effective promotion.
iPhone 5 and its modifications
The gadgets of this series differ in their body. It became larger, which made it possible to significantly change the filling. However, it is lighter in weight than previous models. Compact and fits comfortably in the hand. As for the RAM, it is 1 GB.
What is the RAM in the iPhone
The main advantage of the iPhone in comparison with devices based on Android is the rational use of resources. The iOS platform is aimed at the maximum possible and efficient use of the gadget, which makes it comfortable. Despite this, time passes, and the requirements for gadgets are growing, including for RAM. Over time, the device works more slowly.
When buying a new iPhone, you should pay attention first of all to the amount of RAM, especially since they do not have additional slots for a memory card. This means that the current number of gigabytes cannot be increased. Therefore, in the acquisition of gadgets from Apple, this is a particularly important characteristic.
Cleaning iPhone RAM
Now we will conduct an experiment to clear the RAM in the iPhone and see how this button combination works. In the previous post, we analyzed how much RAM is in Apple phones and tablets, if you haven’t read it, then here is the RAM in the iPhone.
If, after updating the firmware, installing a bunch of applications, or just by itself, your iPhone starts to slow down, then be sure to try clearing the iPhone’s RAM, this is done simply, without installing additional applications:
- While on the desktop, although it probably doesn’t matter here, the main thing is that the iPhone is just turned on. So when the iPhone is on, we hold down the phone’s power button (Power)
- As soon as the screen with the shutdown slide appears, release the shutdown button (Power)
- And we hold down the Home button, continue to hold it until you return to the desktop or to the last program you use
In such an easy way, the RAM is reset in iPhones and iPads, sometimes it is accompanied by a slight flickering of the screen, sometimes not, the RAM is cleared and the device sometimes stops slowing down and starts working faster.
How to Check iPhone RAM Cleanup
In the iPhone and iPad themselves, there is no standard dispatcher that allows you to monitor the load of RAM (RAM), in iOS you cannot even look at the amount of this RAM itself, so we used the utility. SYSTEM UTIL Dashboard.
- After turning on the iPhone 7 with iOS 11, the application showed 550 Mb of free RAM
- After launching 9 different games and applications, free RAM decreased to 36 Mb
- After completing the steps to clear the RAM in the way described above, the free RAM of the iPhone became. 570 Mb
Based on the example of monitoring the state of the free RAM of the iPhone, we came to the conclusion that the cleaning method works. over, after the RAM is reset, additional free RAM appears even after turning on the seemingly not yet “cluttered” iPhone.
Clearing Cache RAM in iPhone X
All the steps above will clear the RAM cache on the iPhone X as well. But the iPhone X doesn’t have a physical Home button. Therefore, in 10-ke, when performing the third point, use the virtual Home button.
After completing paragraphs 1 and 2, we press the virtual Home on the iPhone screen and hold the Home button in the menu that opens until the working screen with icons appears. To enable the virtual button on the iPhone X screen, turn on. Assistive Touch.
Clearing RAM does not close applications
The RAM cleaning procedure does not close all background applications, if you want to close all running games and programs, then this is still done manually:
Press the Home button twice, all running programs and games seem to hang in the air of the ambiguity mode. With a wave of one finger or several at once, pull applications up and close them completely.
How to change
In normal mode, the computer receives all the settings of the RAM from the SPD. a microcircuit that is soldered on each module. But, if you want to achieve maximum performance, it is advisable to try changing the timings. Of course, you can immediately purchase modules with minimal latency values, but they can cost significantly more.
Memory settings are changed through the BIOS of a personal computer or laptop. There is no universal answer: how to change RAM timings in BIOS.
Memory subsystem customization options can vary greatly on different motherboards. Cheap motherboards and laptops can only provide memory operation in default mode, but the ability to choose RAM timings is not.
In expensive models, there may be access to a large number of settings, in addition to frequency and timings. These parameters are called sub-timings, they can be useful when fine tuning the memory subsystem, for example, during extreme overclocking.
Changing the timings can improve the performance of your computer. For DDR3 memory, this is not the most important parameter and the gain will not be too large, but if the computer works a lot with heavy applications, it should not be neglected. This fully applies to the more modern DDR4.
A noticeably greater effect can be brought about by overclocking the memory in frequency, and in this case, the timings will most likely have to be raised rather than lowered in order to achieve stable operation of memory modules in freelance mode. By the way, similar recommendations can be found when choosing memory for new AMD Ryzen processors. Tests show that to unleash the potential of these processors, memory with maximum frequencies is needed, even at the expense of timings.
It should be noted that tuning the memory subsystem will not give any noticeable result in all cases. There are applications for which only the amount of RAM is important, and fine tuning of delays will give an increase at the level of error. Judging by the results of independent tests, fast memory is loved by computer games, as well as programs for working with graphics and video content.
It should be borne in mind that reducing memory latency too much can lead to unstable operation of the computer and even to the fact that it refuses to start. In this case, you will need to reset the BIOS to default settings, or, if you do not know how to do this, you will have to contact the specialists.
What are RAM timings and their effect on speed
RAM timings are time delays that occur when the CPU is accessing RAM. Time delays in memory bus clock cycles are measured. The lower the timings, the faster the data exchange between the processor and memory.
How to find out
In order to find out the timings of the memory installed in the system, it is not necessary to open the system unit or laptop case. This task can be solved simply by installing the appropriate program. Of the whole variety of applications, it can be noted such as:
- CPU-Z is a free utility that can display detailed information about the computer platform and, in particular, RAM.
- AIDA64. provides information about the configuration of the computer and allows you to test the performance of individual subsystems. The program is paid, but it has a trial period.
- SiSoftware Sandra is another program for obtaining computer configuration information, the Lite version is free.
The capabilities of these applications are more than enough to find out the RAM timings, as well as a lot of other information about the installed hardware.
Using programs is perhaps the only way to get an answer to the question: how to find out the timings of the RAM on a laptop in which the modules are soldered on the motherboard or not labeled, which is very common.
In addition, on many motherboards and laptops, you can go into the BIOS and find where to see the timings of the RAM. Navigation through the BIOS, the names of sections and even designations of timings from different manufacturers may differ slightly, if it is not clear where to look, you should refer to the documentation.
It should be noted right away that you cannot directly compare the timings of memory modules operating at different frequencies, not to mention different types of RAM.
For example, there are two DDR3 memory modules, one operates at 1333 MHz and has latencies of 9-9-9-24, the other has a frequency of 2133 MHz and timings of 11-11-11-31. It would seem that the first has less delays, but in practice the second will be faster due to the higher frequency. Thus, the comparison of timings should be done only for modules operating at the same frequency.
Timings should also be taken into account when choosing memory modules for multichannel mode. The best solution would be to buy a ready-made kit in which all strips have identical characteristics. If this is not possible, then you should look for modules that not only have the same clock frequency and chip organization, but also have the same timings.
How it works and what to look at
In order to obtain the necessary data from memory, the central processor must access the cell at a specific address. The operative memory of a modern computer is organized in the form of pages, that is, fixed sections, ranging in size from several kilobytes to several megabytes. Information about the addresses of these pages is contained in the tables.
It works like this: first, the processor makes a request to the desired table, then to the table row, and only then to the desired column, where it gets access to the page with the data it needs. The memory of modern computers is calculated in gigabytes, and the size of tables is limited, therefore, a multi-level structure is used, where tables are grouped into special “catalogs”.
The speed of execution of all these requests is very high, but still limited by the physical capabilities of a particular architecture. Delays occur when performing almost any operation: when accessing a column or row of a table, when switching between rows in a table, between completing one query and submitting the next, etc. These delays are called timings.
Most manufacturers indicate timings in the marking on the memory modules. It can be 4 digits, for example: 9-9-9-24. or just one, for example CL14. which indicates the most important timing. latency.
The order in which the timings are indicated in the marking is standard:
- Latency comes first (CAS Latency or CL);
- Then RAS to CAS Delay (tRCD);
- Followed by RAS Precharge (tRP);
- And the fourth is Active to Precharge Delay (tRAS).
Let’s take a closer look at what RAM timings affect:
- CAS Latency (CL) or RAM latency is the most important among the timings. Latency is the delay between the moment the processor requests memory and the receipt of this data.
- RAS to CAS Delay (tRCD). the delay between accessing a column of the matrix of RAM page addresses and accessing a row of the same matrix.
- RAS Precharge (tRP). the delay between closing access to one row of the matrix and opening access to another.
- Active to Precharge Delay (tRAS). The delay required to return memory to wait for the next request.
In addition, a parameter such as Command Rate (CMD) may be present in the labeling of the module. The Command Rate indicates the delay that will occur from the moment memory is activated until the first request can be completed. Usually it is indicated after the timings and can have a value of T1 or T2, which corresponds to 1 or 2 clock cycle.
The smaller each of the timings is, the better.
How to set correctly
To start, of course, is to find out the standard settings recommended by the manufacturer for this module. We discussed earlier how to check the timings of the RAM. Then you can look at the statistics on overclocking Internet resources to roughly imagine what you can expect from a particular RAM module.
As noted, incorrect latency values can easily make your computer unable to boot, so find out exactly how you reset your BIOS. over, not only software, but also hardware, in case it is not possible even to enter the BIOS. Information about this can be found in the documentation for the motherboard or on the Internet.
To figure out how to set the timings of the RAM in the BIOS, it usually does not take much time. Documentation may be required the first time, then it will be easier.
All timing changes must be made slowly, it makes sense to change one parameter at a time and only per clock. After that, it is important to check if the computer can start and load the operating system.
Next, it is worth testing how the system will behave under load. To do this, you can use specialized programs or just load the computer well, for example, start a game with high graphics settings for an hour or encoding a high-definition video file. If the computer is stable, you can lower the timings by one more clock cycle. If freezes occur, messages about system errors appear, or programs crash, then you need to discard the changes and go back one step.
Having figured out how to reduce the correct timings of the ddr3 RAM and the more modern ddr4, you should not start experimenting right away. First, it is worth determining, based on the characteristics of your hardware, which is preferable: increase the frequencies or lower the delays. Now, in most cases, a greater effect can be achieved by increasing clock frequencies.
