6 Important Things To Consider Before Buying Used Ram

things to consider before buying used ram

RAM is like the heart of your gaming PC. Without powerful RAM, you will see frame drops as well as a reduction of speed while using your PC or gaming. If you’re building a gaming PC and running low on budget, buying used RAM can be a great idea and save some money for other parts. 

However, there is always a risk in buying something in used condition, especially when it is a computer component. Computer components devalue rapidly because they age too quickly, and their replacements are available within years.

In this article, we’ll go through 6 important things to consider before buying used RAM for your PC:

Things To Consider Before Buying Used Ram

Ram Size

The first thing to consider is Ram’s size. Ram size isn’t confusing, and even the non-techy people can differentiate it. Moreover, the size of RAM also depends upon your processor and your needs. 

If your favorite programs or games can run on just 6-7 GB of RAM, why would you spend money buying a bigger RAM? On the other hand, if you don’t have a powerful processor, it won’t run programs and occupy even half-space of the RAM again. It’s a waste of money.

You are buying used RAM to save some bucks, don’t spend these saved bucks on different storage sizes. So, check your RAM usage and needs and then decide which RAM size would suit you the best.

Here is a detailed RAM size guide according to usage:

4 GB: Outdated, no modern PC can run smoothly on such low storage

6 GB: Acceptable size, won’t annoy you in day to day tasks

8 GB: Good for light gaming, internet browsing, and other stuff

16 GB: Excellent option for Macbook and Windows PCs.

32 GB: Perfect for heavy gamers and software users

64 GB: Good for professionals including engineers, developers, programmers, and workstations


Frequency is another significant factor to consider while buying a used RAM. It is also the speed of RAM, which is expressed as DDR3 6777 MHz or DDR4-4300 in RAM modules and represents the physical storage speed. 

Your device’s storage is permanently storing and retrieving loops based on previously loaded data, with the frequency indicating how many times per second the memory cycles.

While having a high-frequency system is ideal, keep in mind that some motherboards and CPUs may not be capable of supporting specific frequencies. So, check the compatibility before buying used RAM.


Timing, also known as CAS (Column Access Strobe delay), is another feature of your RAM. The CAS latency measures the time for the RAM to obtain and execute an instruction. It’s usually denoted with a sequence of numerals, such as 16-20-22-42.

The timing measurements outside the row access strobe latency are referred to as the serial. Smaller timing values are preferable, but keep in mind that differences in the values have little or no effect on the speed of your PC. However, they can differ a bit in prices. So to be economical while buying a used RAM, look into this factor carefully.


If you are a tech person, you must have heard of this term with RAMs. Otherwise, it is not so commonly known. The RAM particles can indicate how well your RAM will overlock. In simple words, overlock means when your RAM pushes your device’s memory and CPU over its limits. 

For instance, CPUs like Intel Corei7 1160 operate at 4.80GHx. As a result, overclocking a Core i7, 1160 Intel raises its clock rate above 4.80GHz.

There are several articles on the industry, such as Samsung’s B-die, Hynix CJR, Micron, etc. Ensure that the used RAM you are buying comes with one of the particles mentioned above.

The Samsung B-die offers outstanding advantages that set it apart from the competition. It features a DDR4 storage module with a peak speed of around 3200 Hs and a Column Access Strobe latency of 14, making it excellent for achieving ultra-high performance. As a result, if you buy this RAM, you will attain high clock speeds and overall performance.

Single Or Multiple Channels

As you have seen multiple RAM slots in a standard PC, why is that so? What’s the use of various slots? Well, it depends upon the user’s needs. For instance, if you are using 32 GB RAM, it will transmit data from a single slot and channel. 

While on the other hand, if you are using two RAMs of 16 GB each, data will be transferred from 2 channels which are faster and more convenient. Moreover, two 16 GB RAMS will cost you less than one 32 GB RAM in the used market. Just make sure of the compatibility of both RAMs before buying.

Manufacturing Company

Last but not least, check the manufacturing company of the RAM before buying it in used condition because not every maker is reliable. Moreover, having so many different RAM brands on the market, it’s easy to get a fake product, especially if you buy it in used condition. 

The RAM brands are important since only legitimate brands can test DIMMs accurately. There are a lot of companies present; however, the most popular include Samsung, Kingston, Seagate, Adata, Intel, Hyperx Fury, and others.

Having the right brand on your Computer is just as important as having the right internal computer technology, such as high-end graphics cards. So, if you’re looking for RAM, make sure you get it from the top manufacturers. This is something that you can’t underestimate.


For a moment, RAM might seem to be a simple component of your Computer that does not need much attention. But in reality, it can boost your Computer’s performance to the sky or push it into the earth. 

Lastly, you must ensure that your motherboard and CPU’s specifications are compatible with the used RAM you are buying.
