how to change ram speed in bios

how to change ram speed in bios. There is no doubt that RAM (Random Access Memory), also called system memory, plays a fundamental role within the personal computer and on which the performance and response of the system depend, not only on the latest generation desktops. RAM plays a vital role in the performance of the programs and games we use on a daily basis. Because a completely wrong setting would only be extremely harmful. Limit overall performance. It is, therefore, crucial to take notice of this gross error and to automatically change the frequency of RAM in the BIOS via the motherboard from the set to the exact one according to the speed of our RAM to extract it all. Able to support. Computers are worth giving us.

It is self-evident that when purchasing a DDR4 RAM kit for our system you should choose one that is formally supported by our CPU so that any type of data exchange and processing between system memory and processor To avoid “bottleneck”. As carefully as this choice is made, we will be able to get the most out of the BIOS by setting the RAM speed correctly. However, we must understand that the evolution that has taken place in recent decades has allowed us to achieve very high performance, especially as a new way of controlling system memory has been adopted. Let’s see briefly what happened.

What is DDR Memory Controller?

The small-scale process of semiconductor manufacturers, through the discovery of the rapidly evolving lithographic process, has directly affected everything we now see in PCs and all electronic components, even a simple TV. Or smartphone. The same is true of hardware components for personal computers, which have undergone a process of simplification by engineering their layout and reducing on-board chips. Equipped with Push IC (Integrated Circuit), Intel 486 came with the appearance of the first systems focused on Intel 486 which performed various control and processing functions which were previously applied to various chips on PCB (Printed Circuit Board). Was done

Since then, the design exercise has provided for the presence of two large ICs that perform all the basic control functions required for the proper functioning of PCs. The former was traditionally named the North Bridge, while the South Bridge was later renamed due to its positioning on the main board. The first was asked for control functions for communication channels (BUS) between processor (CPU) and system memory (RAM) but also for expansion slots (PCI, PCI-Express, AGP, etc.). Per second, on the other hand, admirable secondary functions such as managing all interfaces on the motherboard (USB, network, serial, parallel, etc.).

This type of engineering has brought a series of performance benefits, performance and cost reductions that have made the PC world accessible to everyone. Further steps taken in recent days have made it possible to move the DDR memory controller from the North Bridge within the processor. This is undoubtedly due to the technicality which has led to an increase in the performance of DDR memories which have been able to achieve increasingly high frequencies from the first version to the latest and hence theoretically previous versions. With high performance; However, this required a new design to reduce access times to system memory (latency) through the processor. We can give credit to AMD which first decided to make this change in the design of its processors belonging to the K8 series with the Athlon 64 and Optron project. While Intel hit the same road.

This recent evolutionary step, still running today with modern AMD Ryzen and Intel Core CPUs, has allowed the performance bar to be raised even higher and thanks to advanced lithographic processes such as the current 7nm from AMD or 10nm from Intel. I have succeeded. Many of the controllers that previously existed in North Bridge and South Bridge in dye (silicone). Currently modern CPUs are equipped with all series of controllers within a few square millimeters that were previously external, as mentioned earlier. Think about the control and management functions of USB ports, networks, Wi-Fi, SATA, SSD and many more.

how to change ram speed in bios CPU

Current CPUs, now via the fourth generation DDR memory controller (DDR4), support different memories with different operating speeds depending on the type of processor purchased. We’ve already mentioned in two articles which memories to buy: if you have the latest generation processor, and not only, with AMD Ryzen you can combine memories of 3200 MHz RAM but more carefully and accurately We recommend that you refer to our final guide for selection. What are the best RAM for Ryzen, you will find a great purchase and many useful tips for testing different models in the market today. If, on the other hand, you have an Intel platform with state-of-the-art Core processors, we suggest you read our second guide and delve deeper into where they are compared to the different models available in the market. Let’s review. Every Intel Core processor needs some memory to choose from the best RAM for Intel as each generation and processor type only supports a specific amount of RAM.

We have tried to explain artificially and simply what a DDR memory controller is because it will help us to understand how to increase the RAM frequency from the BIOS to get better performance from the default configuration by increasing the RAM speed. Go Let’s take a step further and come up with an idea that will be used to set RAM memories correctly.

What is XMP RAM (Extreme Memory Profile): XMP Intel and XMP AMD

Initially known as the Intel Xtreme Memory Profile, it aims to secure and control memories by installing authenticated and compatible memories with this technology on your desktop PC system in conjunction with your Intel processors. To increase RAM speed. We can define a type of overclocking fully automated RAM memory that does not require much knowledge in the field of component overclocking. The goal, as already mentioned, is to increase the overall performance of the system by increasing the frequency of DDR memories directly from the BIOS.

The idea is to create a sort of table of possible configurations on RAM’s operating speed when installed on the main board. This table is a memory on silicone support called EEPROM which is nothing more than flash type memory with a size of 1024 bits or more 2048 bits. This table, also known as the SPD (Serial Presence Detect), encodes all the important operating parameters of each memory module. From these parameters we get different operating frequencies like basic one, other more extreme frequency and finally also related to XMP; The times specified in the access times compared to the operating voltages and available frequencies at different pre-established frequencies. It allows you to have different overlock settings available that can be easily and securely remembered with a few simple steps.

When you start the PC, after the BOOT phase, the BIOS reads these values ​​and, based on the selected one, applies, for each module, a specified frequency, access time and memory to better An operating voltage to manage. All of these parameters are encoded according to the JEDEC Standards (Solid State Technology Division), an international body that certifies standardization in the semiconductor sector and is part of the EIA (Electronic Industries Alliance).

There is also an acronym A-XMP (AMD Xtreme Memory Profile) which refers to some memory modules that have a specially certified time and frequency table for AMD processors. This entry is very common in MSI’s BIOS, but in general we can say that AMD Ryzen CPUs can also load any type of XMP profiles.

Why change RAM frequency in BIOS: Low RAM frequency

The main reason for this, which we will see later, is to intervene to correct the system memory frequency as it will be less than our set. Low RAM frequency means a certain percentage of performance loss compared to a properly configured system. Obviously, it is difficult to estimate the loss of performance, but in all these operations, those who use more memory may become sluggish and may not work well.

We think of all the major applications that are widely used, such as the Office package, editing and modern graphics programs, but also of the operating system itself, which constantly uses RAM memory, and in fact it resides in a specific area. Always in memory. ; In addition to these disadvantages, we have more or less solid things related to applications, but most of all, in terms of the latest generation, especially games that really need RAM to load everything that the processor processes. Intense and permanent use.

The second reason is of logical economic type and is easily explained by the price of RAM purchased. If in the purchase phase we have purchased the right RAM memo for our AMD or Intel system, then we have definitely invested a huge amount and from the performance point of view and budget point of view whatever comes to our mind. I am according to it. If, therefore, we have invested a certain amount of money but on the other hand our performance is not up to our expectations, then in fact we have literally “wasted money” on other components such as CPU, video card, I can invest. SSD drive and much more ..

As we mentioned above, there are many reasons to change the frequency of RAM from BIOS to be the most accurate and it guarantees the best performance based on the kit selected at the time of purchase. However, before intervening by increasing the RAM frequency, we should check and understand whether our installed memory is really operating at a lower frequency than the best frequency.

Change RAM frequency from BIOS: Increase RAM speed.

Before proceeding to increase the frequency of RAM from the BIOS to speed up, it is advisable to note that we have installed RAM on the motherboard in such a way that stable and Free add-ons. Intense use. Therefore, it is advisable to use the SPD (Serial Presence Detect) table to understand whether the installed RAMs are equipped with XMP profile or other overclocking profiles. Once again the valuable CPU-Z application has come to our aid as mentioned earlier, for our entire system and in particular, for our intended purposes, which is related to system RAM. Increases the flow of information.

Once the CPU-Z is opened, all we have to do is stand on the screen marked with the SPD tab. Here we have all the information that would be useful for us to change the frequency of RAM. It may not always reflect the memory parameters as the choice of the slot on which the RAM is installed may not be correct. So we must choose the appropriate slot or slots so that we have access to all the information.

The first part of the screen shows us the memory or production technology, the quantity of each module, the manufacturer, the brand of chips and the model that will be useful to test the compatibility of RAM with motherboard and CPU. In fact, all the speeches are invalid if we made a mistake by purchasing the wrong RAM at the purchase stage and it is not suitable for our system. We should always check this compatibility between different components.

The other side of the screen, on the other hand, shows the timing table. Typically installed memories consist of a table with different configurations according to JEDEC standards (# 1, # 2, etc.) and then one or more tables with XMP configuration. XMP configurations are what allow us to perform an automatic RAM overclock compared to the standard configuration. This will allow us to increase the frequency and consequently RAM without further economic expense. The direct result will be to achieve our goal of increasing speed performance in all areas of use. Let us see below how to use XMP in BIOS and how to activate the XMP profile in BIOS.

How to view RAM frequency

Before explaining how to change the frequency of RAM from BIOS, we need to verify in a few simple steps whether our RAM memory is going to the right and / or the wrong frequency compared to the desired. Furthermore, verifying the operating speed of memories can be very useful if we want to increase the amount of installs and purchase memory modules that are identical or exactly compatible with our previously installed modules. How do you view the RAM frequency? The answer to this question is simple, as we will see below, there are different methods that are very clear and intuitive. We can do this directly from Windows, through some applications and even from the BIOS.

How to view RAM frequency from Windows 10

Verifying RAM operating frequency directly from the operating system is undoubtedly the easiest task, and Microsoft provides us with a very useful tool, the Task Manager, also known as the “old” name of Task Manager. With this tool equipped with the operating system, we can access the information necessary to understand the operating frequency of RAM. To access this information, type “Manage Activities” on the application bar, or just press the right mouse button next to the application bar and select the relevant item.

After opening Task Manager we should first go to the Performance tab where there will be a lot of things related to CPU, memory, disk, network and more. We have to click on the memory where we will see some important information and a very useful graph to understand some of the important functions related to the use of memory and its structure. Beyond the graph we find other information that is useful to us, namely the speed expressed in MHz, which is the value of interest for the purpose of our investigation, and other values ​​such as used slots, type of memory ( Format factor) and how specific it is to the hardware. At the speed that Windows tells us, we can already tell if our memories are going to the right frequency.

How to view RAM frequency from CPU-Z

An application that is really useful for looking at the frequency of RAM is CPU-Z which not only provides information about the speed we will see better but also provides more detailed information about all the components of the hardware. she does. The CPUID application provides a variety of data regarding CPU, main board, memory, graphics and also has a built-in benchmark for some useful tests. Once the application is downloaded and launched, as already mentioned, a lot of information will appear on the details of the hardware system we have.

We need to go to the tab with the name memory to find out the information we need. From here we can extract general information on RAM and some detailed information such as current usage. From the general box we can understand the information about the type of memory already installed or if DDR3, DDR4 or other types. Total installed amounts displayed in GBytes; Operating mode type whether single, dual channel or other types; Finally uncover the screen that corresponds to a certain frequency of the CPU controller.

The second box, which is of interest instead, is the timing in which we can extend the information about the speed of memory to the DRAM frequency line, in this case also in MHz. Note that the actual speed should be double that of the competition shown on the screen, given that it is DDR. If we were actually running RAM at 3200 MHz, we would get a value of about 1600 MHz in the CPU-Z screen. Other information relating to the times used in clocks is CAS latency (CL), RAS to CAS delay (tRCD), RAS charge (tRP), cycle time (tRAS), Row Refresh Cycle Time (tRFC) and command. Rate (CR). As mentioned earlier, what interests us most is the DRAM frequency which determines whether the installed RAM memory is going to the correct frequency or less than the manufacturer’s certification.

How to view RAM frequency from BIOS

If we want to tinker a bit more than the previous two options, we can check the RAM frequency from Windows instead or via CPU-Z we can do it directly through the motherboard BIOS. The modern BIOS, also called UEFI, allows you to see the value of system memory frequencies more clearly, thanks to a much more advanced graphic interface and mouse use than ever before. To access the BIOS, start the PC and press the CANC key to be taken to this new interface after a few snippets.

In modern BIOS we can access it in two modes, namely EASY MODE or ADVANCED MODE. The first mode is the easiest and quickest where we can see all the important parameters of our system. Usually in many BIOS pressing the F2 key switches between the two modes. For those with less experience, we recommend staying in EASY mode.

In our Gigabyte BIOS, the memory frequency shows the original, which in our example is set at 3600 MHz. This is the actual amount of RAM memory we have decided to install on the motherboard. In other BIOS we may find entries such as RAM speed or DDR speed or frequency. Obviously, this varies from manufacturer to manufacturer, depending on how they implement this entry into their BIOS. Once we have learned the frequency of memories, we can exit with the ESC key or by going to the EXIT item, without saving anything. (Exit secure w / o).

If you would like to know more about how to view the frequency of RAM, we invite you to read our guide where we will review this topic in more detail.


In this article of how to change ram speed in bios we have shown you how to easily and quickly overclock memory. Take advantage of the RAM capacity installed on our system. The goal is to safely increase RAM frequencies and consequently increase speeds completely independently. Once you understand how to view the RAM frequency in different ways, ie from Windows, CPU-Z or directly from the BIOS, just remember the XMP profile stored in the SPD table and change it to the final RAM. Set up correctly. Frequency

This simple operation, made possible by the BIOS, allows you to take full advantage of the speed of memory in all the daily or intensive use that we make for our desktop PCs, especially gaming, speed on our system. And getting feedback. So, why not take advantage of our hardware capabilities and load the XMP profile into the BIOS?

Finally, in addition to XMP profiles, there is a possibility to select other multipliers which are expressed in FSB: RAM ratio and which affect the final frequency which, with proper hardware, reaches beyond 5 GHz. Can A real memory overclocking exercise and these methods are especially safe for expert users. It’s not as fast as loading an XMP profile from the BIOS.
