The electronic circuitry used to store binary data is known as computer memory. This is achieved by switching very small electronic control positions on or off. In binary code, 1 is denoted by the on position and 0 is denoted by the off position.
A bit refers to 0 and 1. Bytes, which consist of eight bits, are groups separated by switches. The basic building block of computer data is the byte, which is an 8-bit number capable of representing any decimal value ranging from 0 (represented by all 0s) to 255 (represented by all 1s).
Motherboards are designed to be compatible with certain types of memory, including SDRAM, DDR SDRAM, Rambus, EDO RAM, and burst-EDO RAM. In addition, motherboards have limitations on the speed of memory modules they can accommodate, such as only accepting within a certain range such as 800 or 1600 MHz.
The speed of a computer’s performance is directly proportional to the speed of its memory. For consistent memory performance, all memory modules installed in the computer must have the correct speed. If you set up your motherboard with two types of memory with different speeds, the chips will function at a slower speed.
How to Determine the Optimal Amount of RAM Memory
Increasing the system memory to the maximum limit will improve system performance. The increased memory capacity allows the computer to operate multiple programs and processes simultaneously without a hitch. Improving computer performance is usually most easily achieved through adding extra memory.
Microsoft sets the minimum and recommended memory requirements for all its Windows editions, while developers determine the minimum thresholds for their respective programs.
It should be noted that the minimum requirements set by Microsoft are the bare minimum and machines with limited RAM can only handle operating systems with very limited functionality.
As per the current scenario, for a Windows 11-equipped computer, it is essential to have a minimum of 4GB of memory to guarantee the operating system works well, and having 8GB or more is considered ideal, such as for tasks like multimedia.
Computer performance is the most obvious deciding factor. If your computer is working properly, there’s rarely a reason to upgrade it. If your computer is running slowly, especially after installing new software, then you should consider adding additional memory.
Determining the Right RAM Memory for Your Computer
Common approaches to identifying the appropriate memory specifications for a particular computer include reading the computer or motherboard manual, browsing the manufacturer’s website, or contacting the manufacturer directly.
You can also visit the official website of the memory manufacturer. Enter information such as the computer or motherboard brand and model number when prompted. The software is designed to identify each compatible memory module for a particular computer or motherboard.
One option to get memory is through online retailers, while another option is to visit physical stores.
Computer Reports Incorrect Amount of RAM Memory
The computer may indicate the wrong amount of memory installed for various reasons:
- On certain devices, part of the main memory is used by the onboard video, which results in less reserved memory than the total indicated by the computer. The video memory allocation settings can be changed via BIOS.
- If the number displayed is inaccurate, please remember that a kilobyte consists of 1024 bytes, while a megabyte consists of 1024 kilobytes. So, when your device displays 1,024 MB of memory, it is equivalent to 1 GB of RAM.
- There is a problem if the memory size deviates from the entire memory module or partially installed memory module. It is important to verify that the module installation is correct, the compatibility of the memory with the motherboard, and ensure that the memory matches other existing memory (if you are using different memory modules).
Installing memory on some motherboards has rules. Do you have to install it in slot 0, slot 1, slot 2, and so on? Refer to the motherboard manual for installation rules. - If you install memory beyond the memory capacity allowed on the motherboard, your computer may display the highest memory limit supported by the motherboard.
How to install RAM
Installing memory is an easy task. Start by ensuring that you adhere to common routines to prevent static electricity. Before proceeding, be sure to touch any uncovered metal surfaces on the case. Insert the memory module directly into the slot while ensuring that the grooves on the module align with the grooves on the slot.
- Make sure you use the appropriate RAM module that is compatible with your motherboard.
- It is important to carefully follow the guidelines provided by the computer, motherboard, and memory manufacturers.
- Start with the memory slot that has the smallest numerical value, which can be either 0 (slot 0) or 1 (slot 1).
- Arrange the memory modules by capacity in ascending order, placing the highest capacity module in the first slot.
Once you have successfully installed the memory, turn on the computer and verify the newly added memory. If there is no diagnostic software, it is recommended to use programs that require a lot of memory such as office tools, photo or video editing software, or games that require a lot of graphics.
Solving Memory Problems
One visible sign is that the problem appears as soon as you add new memory, which indicates that memory could be the root of the problem. Additional indications of memory-related issues consist of regular freezes (when the mouse cursor fails to respond and the Num Lock indicator on the keyboard remains stuck or off), or a sudden absence of visual displays.
Of course, the presence of these symptoms does not necessarily confirm a memory problem. If you receive memory-related error notifications, especially during the early stages of booting, your system is likely experiencing memory issues.
Many error messages related to memory can be deceptive and may not necessarily imply a problem with the memory itself. It is important to check for any issues related to memory error messages.

Memory Error Message
Error messages can be unhelpful and unclear. Some messages are irrelevant, while others are accurate. Error messages may not originate from Windows or a program, and sometimes initial boot errors may prevent the computer from starting.
Memory errors can occur due to the wrong type, incompatible modules, or incorrect installation. Examples include memory incompatibility and memory parity errors.
Sometimes Windows displays a BSOD blue screen, for memory-related issues, copy the text in the message, including hexadecimal numbers. Search appropriately in the Microsoft Knowledge Base or Google, using quotes or Advanced Search to avoid typing errors.
Out-of-memory errors are common. Save the document due to low memory. It is usually a program error, not a memory problem. Close the program to clear the error message. Restart the program and check if there is a recurring error.
Memory Testing Hardware
Devices like the one offered by CST accurately test memory quickly and efficiently. Expensive, it is only feasible for frequent, large-scale memory testing. Small workshops don’t have them. To test your memory, look for a business (like your supplier) that offers to test for a fee. Transport the memory in an anti-static container, with owner identification marked.
Memory Testing Software
Although memory testing software has limited capabilities compared to hardware testing tools, it is still an affordable option.
Memtest86 is a free software for testing memory that is quite popular. Although it is free, it can still provide reliable results for users. Be sure to review the user manual document included in the zip download before using it.
Solving Memory Problems
When trying any of the following, be sure to turn off the power. Be sure to perform a test on the system after any changes are made to verify that the problem has been fixed. Take note of any modifications so that you do not repeat them in the future.
Start by verifying that all modules are properly installed. Next, remove the modules one by one while ensuring that the guidelines for installing memory outlined earlier in this section are strictly adhered to.
One can try to improve DIMM performance by using a pencil eraser to clean the contacts or memory pins. Next, use compressed air, such as a blower, to remove any accumulated dust from the slot. Try again by inserting the module once more.
If these methods prove ineffective or the memory test detects a faulty module, the ideal solution is to replace it with a new one and then evaluate the system to ensure the problem has been resolved.
Memory Settings in BIOS
Certain BIOS configurations offer options for configuring memory. Usually, it is recommended not to make any changes to most of these configurations.
As mentioned earlier, the changes you can make to the memory configuration relate to the use of ECC/parity or non-ECC memory. In most cases, ECC/parity memory is considered unnecessary unless it is used on a file server.
One example where this configuration adjustment may be needed is if you have functional non-parity memory from a computer that cannot be repaired, and have another computer that requires similar memory of the same speed and type, which usually requires ECC or parity memory.
Assuming your BIOS allows it, switch the setting to non-parity/ECC before replacing the entire parity/ECC memory of an irreparably damaged computer with non-parity/ECC memory. Usually, it is recommended not to make any adjustments to the BIOS memory settings and leave them in their original state.
