If you see only 2 GB out of 12 GB RAM, it could be due to reserved memory for hardware or system settings like the BIOS. To fix this, try adjusting your BIOS settings or checking for reserved hardware. You may also check memory allocation in the Resource Monitor for more details.
This article will explore the reasons behind this phenomenon, offer solutions to help you maximize the available memory, and discuss potential causes.
What is RAM and Why Does It Matter?
Before we dive deeper into the issue, let’s quickly explain what RAM (Random Access Memory) is and why it’s so essential for your system’s performance. RAM acts as your computer’s short-term memory, temporarily holding data actively being processed. The more RAM your computer has, the better it can handle multiple tasks or applications simultaneously. Without enough
RAM, your system may struggle to keep up, causing lag or slowdowns. RAM is a key component in determining how smooth your experience will be when running various programs. It supports your computer’s ability to run efficiently, especially when several applications are open simultaneously. So, understanding your RAM usage can be crucial to ensuring your computer is working at its best.
Can I use different-sized RAM sticks in my system?
Yes, you can use different-sized RAM sticks in your system, but it’s not ideal. While it may work, it could cause performance issues, such as slower speeds or instability. For the best performance, using RAM sticks of the same size and speed is always recommended.
This ensures that both sticks can work together efficiently, improving your system’s performance. Additionally, using identical RAM sticks helps maintain a balance between your memory channels, which is essential for smooth multitasking. If upgrading your RAM, it’s best to match the existing stick or replace both for maximum benefit.
Why Am I Seeing Only 2 GB Out of 12 GB RAM?
It can be pretty frustrating when you know your system should have more RAM, but only a small portion is being recognized. Let’s go over a few possible reasons why this could be happening and what you can do about it.
Check for 32-bit System Limitation:
One common reason could be that your operating system runs on a 32-bit version. A 32-bit OS can only recognize a maximum of 4 GB of RAM, which may limit the amount of RAM your computer can use. If so, upgrading to a 64-bit operating system can help you access 12 GB.
Incorrect BIOS Settings:
Another possibility is that your BIOS (Basic Input/Output System) settings might restrict your RAM usage. Sometimes, the system may not be set to allocate the full amount of available RAM. Checking and adjusting these settings can help your computer recognize all your installed RAM.
Faulty RAM or Hardware Issues:
Sometimes, faulty RAM or improper installation can cause your computer to recognize only part of the installed memory. It’s worth reseating or trying the RAM sticks individually to check for any issues. If your hardware is damaged, it may need to be replaced.

Shared RAM with Integrated Graphics:
Some of your system’s RAM may be allocated to the graphics processor if you’re using integrated graphics. This means part of your 12 GB might be used for graphics tasks, leaving you with less memory for other applications. You can check your settings to see how much RAM is allocated to the integrated graphics.
Software or System Errors:
Lastly, software glitches or system errors might cause the operating system to misreport the amount of RAM. A quick restart, checking for updates, or running a diagnostic tool could solve this issue and ensure your system recognizes all the installed RAM.
How Do I Check How Much RAM Is Being Reserved?
To check how much RAM is being reserved, start by opening the Resource Monitor. You can do this by typing “resmon” in the Start menu and pressing Enter. Once the Resource Monitor is open, navigate to the Memory tab. Here, you’ll find information about how much RAM is reserved for hardware and system processes.
The “Hardware Reserved” section will show the amount for integrated graphics or other components. Reviewing this’ll help you better understand how your system’s memory is being used. If you’re still unsure, you can also check the Task Manager for more details about active processes using memory.
Is it Normal for the System to Reserve Part of the RAM for Hardware?
Yes, it’s entirely normal for the system to reserve a portion of the RAM for hardware, and here’s why:
Reserved RAM for Integrated Graphics:
First off, if your computer uses integrated graphics (meaning it doesn’t have a dedicated graphics card), some of your system’s RAM will be reserved to support the graphics processing. This allows your system to allocate memory for visual tasks, like rendering images or videos, without needing extra hardware.
Peripheral Devices Requiring Memory:
Next, your system may also reserve RAM for other hardware components, such as network cards, audio devices, or storage controllers. These peripherals need some of the system’s memory to function efficiently, ensuring your computer runs smoothly.
3. BIOS Settings and System Configuration
It’s also worth noting that your BIOS or UEFI settings might have reserved some RAM for these purposes. For example, the amount of RAM allocated to the integrated graphics can usually be adjusted in the BIOS, but some memory will always be used for hardware tasks.
Dynamic Allocation of Memory:
Furthermore, the system dynamically allocates RAM based on the workload and the needs of connected devices. This means that the amount of RAM reserved for hardware can vary depending on what your computer is doing at any given moment.
Why is my 64-bit Windows showing less RAM than installed?
| Reason | Explanation |
| Reserved Memory for Hardware | A defective RAM module or motherboard issue can reduce the available RAM shown in Windows. |
| Incorrect BIOS Settings | Memory remapping might be disabled in the BIOS, causing the system to reserve more RAM than needed. |
| Faulty or Outdated Drivers | Outdated or incompatible drivers could cause RAM not to be fully recognized by Windows. |
| Operating System Limitations | If you’re running a version of Windows that doesn’t support large amounts of RAM, it may limit the visible RAM. |
| Hardware Issues | A defective RAM module or motherboard issue can lead to a reduction in the available RAM shown in Windows. |
Why is my system running slow even with enough RAM?
Several factors could be at play if your system is running slow despite having enough RAM. For instance, a slow hard drive can drastically impact performance. Additionally, outdated drivers might not allow your system to function at its full potential. Another possible reason is excessive background processes, which can consume CPU power and slow everything down.
It’s also worth checking for malware, which can use up system resources and cause sluggishness. Finally, a cluttered operating system with too many unnecessary programs might contribute to the issue. In some cases, an overfilled hard drive can also cause slowdowns, limiting available space for your system to run smoothly. Ensuring there’s adequate space and optimizing your storage can improve overall performance.
What is the difference between DDR3 and DDR4 RAM?
| Feature | DDR3 | DDR4 |
|---|---|---|
| Speed | Slower, up to 2133 MHz. | Faster, up to 5000 MHz. |
| Power | Consumes 1.5V, higher power. | More efficient, consumes 1.2V. |
| Capacity | Up to 16GB per stick. | Up to 64GB per stick. |
| Compatibility | Works with older systems. | Not compatible with DDR3. |
| Price | More affordable. | Slightly more expensive. |
| Latency | Higher latency. | Lower latency. |
