Can CPU Cause Memory Errors? [Figure Out CPU-Memory Link]

Written By Steven Arends

If the CPU is like your brain, memory is like the heart. If either of these components malfunctions, your entire system becomes unstable.

Usually, faults in your RAMs cause memory errors. But can your processor do the same?can-cpu-cause-memory-errors

You will get your answer in this article. Furthermore, we will explore the CPU-Memory bond, and how to detect and diagnose such errors.

So, without further ado, let’s jump in.

Can A Bad CPU Cause Memory Errors?

Yes, your CPU can cause memory errors, although memory errors typically happen for faulty RAM. Overclocking your processor beyond safe frequency/voltage or a faulty L1, L2 or L3 cache can create problems in your computer memory. Also, your CPU register can cause similar things.

The register and adequate CPU cache is much needed for executing any program. Any issue in here can cause severe problem in your computer.

In this portion, I will describe when your CPU can cause memory errors. It will help you differentiate from the Memory Errors caused by RAM. Let’s see.

These are the situations when a CPU can cause memory issues on your PC:

  • A processor can cause memory errors when you overclock it beyond its recommended frequency or voltage. Overclocking can cause the CPU to generate excess heat, leading to memory errors and other system instability.
  • You may face memory errors when there is an issue with the CPU cache. The CPU cache is a small amount of high-speed memory to store high-priority data. If there’s a problem with the CPU cache, it can cause memory errors or system instability.

Additionally, a faulty CPU can cause memory errors. If the CPU is not functioning properly, it won’t correctly read or write to memory, leading to memory errors.

In short, while memory errors happen for faulty RAM, your CPU can also cause memory errors in certain situations.

Does a Bad Processor Cause Ram Issues?

does-a-bad-processor-cause-ram-issuesYes, a bad CPU can cause RAM dysfunction. Your CPU plays a critical role to manage data flow between the RAM and other components of the computer system. When the CPU malfunctions, it can’t access or process data from RAM. It can lead to memory errors.

For example, if you identify a faulty CPU, it may not execute instructions or can generate excessive heat, making the RAM unstable.

You must read our article on how CPU and RAM work together. It will help you to understand the CPU-Memory link easily.

Additionally, a faulty processor can cause other malfunctions, which can indirectly cause RAM errors. For example, if the memory controller is defective, it won’t manage the data flow between the CPU and RAM.

So, when you are experiencing memory errors, you must thoroughly test and diagnose all components of your PC to identify the root of the problem.

What’s the Difference Between CPU Memory Error & Memory Error By RAM?

The main difference between a CPU memory error and a memory error for RAM is the source of the problem. Because both errors can cause system crashes, data corruption, system instability, etc. Also, you need to apply different solutions for these two memory errors.

A CPU memory error typically happens when there’s a problem with the CPU or its related components, such as the CPU cache or memory controller.

On the other hand, A memory read error caused by RAM occurs when a value read from RAM doesn’t match the expected value.

Here you will see the core difference between these two errors. It will help you to differentiate the reasons.

Let’s see the core difference between CPU Memory Error & Memory Error By RAM:

CPU Memory ErrorRAM Memory Error
CPU memory errors occur when the CPU malfunctions and can’t access, or process data stored in RAM.RAM Memory errors happen when the RAM modules malfunction and can not save, read or write data.
It crashes your system, corrupts data, and affects your system’s overall performance.You will see a similar effect for memory error By RAM also.
Various factors, including faulty hardware, software bugs, etc. can cause this error.RAM Memory errors typically happen for defective RAM modules.
You should replace the CPU or other related components, depending on the cause of the error.You need to replace the faulty RAM module motherboard to solve it.

These are the key difference between CPU Memory Error and RAM Memory Error. The following example will make the concept clearer.

For Example:  when you overclock your processor beyond its recommended frequency or voltage, the CPU generates excess heat or instability which can cause memory issues. Similarly, if there is a problem with the CPU cache, it can cause memory errors or other system instability.
On the flip side, If the RAM is faulty or not compatible with the motherboard or other components in the system, it may cause memory errors.

How to Detect CPU Memory Error

Detecting the memory error caused by your CPU can be challenging because the symptoms vary depending on the nature and severity of the error. Also, sometimes the symptoms are similar to the error caused by RAM.

But in this portion, I will show you some signs of CPU Memory Errors. It will help you to differentiate the error from the RAM

Here are a few common symptoms that may indicate a CPU memory error: 

  • System crashes: When your system crashes or freezes often, and without any apparent reason, it’s a sign of a CPU memory error.
  • Blue screen of death (BSOD): BSOD occurs when the system encounters a critical error and stops operating. The BSOD can happen due to bad CPU memory.
  • System instability: A CPU memory error can make your overall system unstable. When this happens, you will face problems like crashed apps, or the OS becoming sluggish or unresponsive.
  • Corrupted or lost data: When your CPU can’t read or write properly to memory, your data gets corrupted or lost.

You should use diagnostic software to check the CPU and memory when you see these symptoms. Modern PCs have built-in diagnostic tools you can access either during startup or from within the operating system.

Alternatively, you can use third-party diagnostic software to test the CPU and memory of your system.


What is the relationship between CPU and memory?

The primary connection between the CPU and memory is that the CPU uses memory to save frequently used data while executing any program.

Does the CPU manage memory?

Yes, the CPU mainly manages the registers & the cache memory and instructs RAM and ROM to open any programs.

Can I fix a damaged CPU?

No. you can’t fix any damaged CPU. You have to replace it.


To summarize, the CPU and memory are tightly linked components of a computer system, and a CPU can damage the memory. Though the main culprits of memory errors are RAM, your CPU cache can cause similar issues once in a while.
