A silver lining was seen in the computing space when DDR3 Ram launched in 2007, this was the biggest computer revolution of the year and the impact was instantly felt. You enjoy more performance than the previous model like the DDR1 and DDR2, and this has been the case for many years. 

DDR4 came later on and DDR5 is about to eclipse the success of all predecessor rams in the market. But just then, there is a reason why DDR3 has stayed in the market for these impressive years, and trust me, this ram is still a fan favorite as they are still heavily sold. 

This article will compare the DDR3 1600MHz ram against its brother DDR3 1866MHz, while these rams were the best of their era, there is a thin line between them, so let’s find it out. 

1600MHz vs 1866MHz 

Just before we dive into the gist which will be to compare these leading rams, taking a look at them and exploring their individual unique qualities is a thing of delight. Let’s begin then by looking at the DDR3 Ram and all it stands for. 

1600MHz DDR3 Ram 

Codename PC-12800 owing to its maximum peak transfer of 12800MB/s, this ram stands tall on the list of impressive ram offerings that has hit the global stage and this is quite impressive. You can easily play your entry-level games on this ram without hitches of any kind. 

This is not all, mid-range games are also not excluded as you enjoy a wide range of offerings that will suit your taste for gaming excellence and superior performance. Similarly, if you are a fan of AAA games, this ram loads them with ease, however, it cannot load all AAA games. 

Renewed as the fastest ram of its era, it is best outperformed by the DDR4 ram. Furthermore, comparing it with the DDR3 1866MHz makes for an equal comparison as they are in the same category and how it performs will be fully attended to in the comparison section. 

There is a major problem with this ram, and this may seem like the most interesting thing. Overclocking is a challenge, the reason for this owes largely to the low-quality heat spreaders the ram comes with. You stand a chance of losing your RAM owing to overheating. 

1866MHz DDR3 

This is an improvement on the 1600MHz ram and as it is always notably, you will get the improvements lining up just where you need them most. First is the higher clock speed that is available on this ram, it comes with a fabulous 14933MHz peak transfer speed, making it almost 2000MHz faster than the DDR3 1600.

Similarly, as you will expect, you enjoy advanced gaming support with improved satisfaction that comes with hitting your highs and making the best runs of all time. You will love this feature and we are quite sure! Multitasking is another area where this ram greatly excels at and it is fantastic. 

There are no glitches when it comes to accessing your files and you are sure of enjoying the best options at your disposal here.

When it comes to choosing your ram, your ram clock speed is one of the most central aspects of a review to consider. The more clock speeds the better, interestingly your clock speed determines how fast or slows your computer runs. So deciding for the best here is a wise choice. 

Similarly, when it comes to gaming and streaming, taking down those hard computing functions like modeling and rendering, your computer ram will have to be great to get this through. This is where your computer ram is also very important. 

Not just the ram, things like your computer bandwidth and CAS latency are other important areas to look at before considering the best ram to go with and how to settle for it. 

Here is  how we compare these two rams: 


Whether you are using your ram for basic computing operations or gaming, the efficiency of the ram rests solely on the capacity and this is where the 1866MHz DDR3 Ram excels greatly. The 14933MHz clock speed is just fantastic, and it makes for a great outing. 

Compatibility and cost

When it comes to cost, there is a ram that tops the list. The 1600MHz ram is cheaper and always in stock. You can easily run a hectic search for the 1866MHz ram, but the same cannot be said of the 1600MHz it is readily available. Similarly, the 1600MHz ram is compatible with all motherboards.

Gaming and advanced use 

Here is where the 1800MHz DDR3 Ram excels greatly, it ticks the boxes here and takes control of its space. The gaming experience is amazing and delightful, you will have a long run of smooth gaming interface with hitches on this ram. And not just gaming, it supports your everyday use.


We are here at a crossroad, the 1600MHz and 1800MHz are twin ram with an amazing collection of features that make them impressive for use. They tick the box for budget and premium performance at the cost that fits your pocket. It is easy to settle somewhere. 

If budget is your concern, then the 1600MHz DDR3 Ram will fit the list for you. If you are willing to go overboard a little with your budget while you enjoy the finest features of your computer, then the 1800MHz ram will offer you the best coverage. So the options are yours to take!
