Memory is an important topic to understand, particularly as your computer’s memory becomes more and more limited. This introduction will help you become familiar with what memory is and how it works in a general sense.
The “memory in psychology” is a term that refers to the brain’s ability to store and recall information. Memory can be divided into two types: short-term and long-term memory. The “short-term memory” is the amount of time it takes for your brain to process an event, such as what you just ate or heard. It then stores the information in the “long-term memory”.
It’s not just about how much RAM (Random Access Memory) or “Memory” you have when it comes to RAM!
While this is generally the most important component of memory, its speed and latency must also be considered.

RAM gives your CPU access to a temporary data storage space so that it may perform tasks fast and effectively. The CPU has immediate access to RAM, but not to other types of data storage (like your hard drive). As a result, any data that has to be accessed quickly is often transferred into this working memory region (RAM).
For rapid functioning, you’ll need ample working memory space. Without adequate RAM, your CPU will have to obtain data from other parts of your computer, lengthening the time it takes to complete tasks and causing obvious lag and longer loading times.

Considerations in Making a Decision
Memory is reasonably priced. The quantity of RAM you’ll need is determined by how you’ll use your computer. Generally speaking, the more work your computer does, the more RAM it will need.
When purchasing for memory, keep the following factors in mind:
- RAM size refers to the amount of memory available, which is commonly expressed in gigabytes (GB). When it comes to RAM, this is the most significant issue, and other metrics such as latency, speed, and so on are mostly irrelevant to the ordinary user. A bigger number means that you can store more data in memory, thus a larger number is preferable.
- DDR3 or DDR4 is the RAM type. DDR4 is identical to DDR3, except it uses less power to attain the same level of performance.
- Latency – Memory module latency measured in clock cycles, which may be converted to time (typically in nano seconds). If you’re designing a gaming computer, this statistic won’t have much of an impact on overall performance since it’s almost undetectable. It’s often written as “CL” (CAS Delay), for example, CL10, which denotes a CAS latency of 10 clock cycles. A lower latency indicates a quicker reaction.
- The frequency of the memory modules, measured in megahertz (MHz) (also known as the number of clock cycles per second). It is preferable to have a greater frequency.
- Choose a recognized brand that has a decent guarantee.
- Voltage – to reach their speed, certain memory modules demand a greater voltage than standard. Make sure your motherboard can handle it. DDR3L, for example, is a lower voltage RAM type than DDR3 (it operates at 1.35 volts) (which runs on 1.5 volts). DDR4 voltage has dropped to 1.2 volts.
- Check to see whether the RAM is officially supported by your motherboard. This is an important phase that many system designers skip. Look for the memory component numbers that your motherboard manufacturer officially supports on their website.

What kind of RAM do I require?
There are two techniques to determine what kind of RAM is presently installed in your computer:
- Download and install a diagnostic utility that will tell you what kind of RAM you have installed on your computer.
- Look at the side of your RAM stick when you open your PC (it should have the type: DDR2, DDR3, DDR4 written on it somewhere, or otherwise you can look up the specifications based on the model and brand).
Another option is to go by the year of manufacturing, although it’s always a good idea to double-check the kind of RAM to ensure you obtain the proper one for your motherboard.
- DDR2 (before 2007)
- DDR2 & DDR3 (2007–2012) (some DDR2 still around)
- DDR3 (Double Data Rate) (2012–2015)
- From 2016 forward, DDR3 and DDR4 will be used (DDR4 still rare at this stage, but becoming more popular with the release of Skylake architecture).
What does it mean to’match’ RAM sticks?
Most motherboards contain multiple RAM slots, allowing for the installation of additional RAM sticks. Installing RAM in’matched’ sticks, which are two or more sticks of the same model, brand, and size, is frequent.
The advantages are that there will be no compatibility difficulties between paired sticks.
Mixing brands, models, and sizes may work in certain cases, but it can also cause system instability and crashes.
Wherever feasible, we always advocate using matching RAM. When feasible, keep to the same brand, model, and amount of memory, particularly for bigger RAM capacities (mismatching larger sized sticks has a greater impact on your system).
If at all feasible, acquire your RAM sticks at the same time, since manufacturers sometimes revise/upgrade their product lines.
Can I mix and match brands?
Yes, albeit it is not advised. The system will continue to function, but there is a chance that various brands could have compatibility difficulties, which might cause instability or system failures.
You may be better off using a single stick of RAM than attempting to pair incompatible manufacturers, depending on how much RAM your system presently uses.
In certain cases, if you don’t have enough RAM, the extra RAM capacity may provide benefits that exceed any potential compatibility concerns.
Can I mix and match sizes?
Sizes of RAM sticks may be mixed, however if feasible, keep to the same brand/model to prevent compatibility concerns.
Is it possible to blend speeds?
The RAM’s speed is measured in Hertz (Hz). To minimize compatibility concerns, we suggest that all memory have the same brand and speed grade (same Hz).
It is, however, feasible to combine RAM sticks of various speeds. Keep in mind that the motherboard will function at the speed of the lowest-graded RAM stick, so one sluggish RAM stick may slow down the whole system.
Even though the fundamental timings of RAM sticks are the same, sub-timings may make a difference. These sub-timings may be handled differently by various brands. Using’matched sticks’ will give you the greatest results.
Should I buy two smaller sticks or one large stick?
This is a frequently asked topic about RAM setup for a certain memory size. Is it preferable to acquire two 2GB sticks or one 4GB stick, for example?
The user determines the answer.
If your motherboard has on-board integrated graphics, having two RAM sticks allows you to receive ‘dual channel speeds’ (a doubling of bandwidth), which may offer you a substantial performance improvement.
However, if you’re using a dedicated graphics card, dual channel memory rates may not be a significant benefit.
It’s advisable to install one bigger stick in this scenario, since it gives you more options for upgrading to a second (hopefully matched) stick later on without taking up too many RAM slots on your motherboard.
Memory loss is a condition where the brain has lost some of its ability to store information. Memory loss can be caused by various factors, including aging, Alzheimer’s disease, and traumatic brain injury. Reference: memory loss.
Frequently Asked Questions
What is memory in simple words?
A: Memory is a physical storage device that can be found in many different devices and machines. Its used to retain data such as programs, games, pictures, movies etc…
What are the 4 types of memory?
A: There are four main types of memory, short term/working memory (recently accessed information), long term/storage memory (remembered information that was not recently accessed) and two intermediate levels of temporary storage. The last one is called deep or associative because it contains memories without any specific content, just the association between a word and an object.
What are the 3 types of memory?
A: 1. Short-term memory is the ability to hold and process information in your immediate environment for a short period of time without forgetting it or needing to reference something else. 2. Long-term memory stores more complex memories, such as events of our lives that we want to remember and understand better, like skills learned from childhood until adulthood (e.g., how to ride a bike). 3. Procedural memory consists of implicit memories—the skillful motor patterns you already know how perform even if you dont think about them consciously; these are things like riding a bicycle or running fast on grass without slipping up
