is ddr4 2666 ram good

In 2020, you should be getting DDR4 2666 RAM, which is at the low end of DDR4 RAM. Low-speed RAM doesn’t affect Intel CPUs as much as AMD Ryzen CPUs do. My recommendation would be DDR4 3000MHz, with 3200 being the most cost-effective. If 3200 and 3600 are priced similarly, then 3600 would be worth buying unless the difference is significant. Is DDR4 2666 RAM good? Yes it is for the Intel CPU. However, while working with an AMD, you might need to DDR4 which has a very high frequency.

The recommended memory for gaming in 2022 is 16GB. Take the time to research the recommended specifications for your games and then adjust them according to your budget. To get the most out of your motherboard, you will need to get two sticks of RAM rather than a single stick since dual-channel memory is faster on motherboards that have dual channels. Using 16GB as an example, the number of GBs would be 2×8, 8GB would be 2×4, and so on.

Your budget really determines what you can afford. By not using Intel, you can save some money by getting faster memory if you go with Ryzen. Intel CPUs can handle 2666MHz ram. For AMD, however, 3200 or higher ram works much better. Faster ram will increase FPS for AMD CPUs. As long as your CPU is Intel, you should be fine. On YouTube, you can see a comparison of AMD products.

2666 vs. 3000 RAM: Which Is Better for Your Gaming Rig?

A PC builder should be aware that latency, frequency, and size determine the performance, capabilities, and speed of RAM. In this article, we will explain these factors so that you can make an informed decision about whether to go with 2666MHz or 3000MHz.

RAM clock speeds are commonly referred to as frequency. A typical range is between 2400MHz and 4400MHz, measured in MHz.

Data on your hard drive, SSD, or any other storage device will be retrieved faster by your computer’s processor when your RAM clock speed is higher. In games and other real-world situations, you’ll find that better RAM gives you better performance.

According to its Megahertz or MHz, a RAM can access its memory up to 100 times per second. MHZ ratings indicate how fast RAM is, as you might expect. The following caveats do apply, but we’ll discuss them later.

In evaluating a RAM’s speed, one should not overlook its latency – also called CAS latency or Column Address Strobe latency. An action or command is recognized by a RAM after it has taken CAS latency. Similarly, your mouse will take a little bit of time to respond to a command and your monitor will take a little bit of time to display a visual.

Four numbers are usually recorded as CAS latency: 14-14-18-32. For RAM to register a command, it needs a certain number of clock cycles. To determine the RAM’s CAS latency, we use the first number from the string of numbers. Your RAM will generally be faster and better if its number is lower.

There can be a difference in CAS latency between two RAMs, even though they have the same transfer rate. There can be a difference of 14-14-14-34 years between two different 3000 DDR4 RAMs and a difference of 16-18-19-38 years between two different 3000 DDR4 RAMs. CAS latency rating for one is 14, and CAS latency rating for the other is 16. There are other names for CAS latency. CAS 14 timing, CAS 14 or CL14 refers to RAM kits with a latency of 14.

 RAM Size

RAM is measured by its total memory capacity. There are several RAM sizes that are familiar to you, including 4GB, 8GB, 16GB, and 32GB. RAM capacity increases the efficiency of your computer. Multitasking will be easier and your PC will load programs faster.

Despite their smaller sizes, RAMs are faster than SSDs and HDDs, which explains why RAMs can improve the performance of a computer.

The data which has been stored on your storage device takes time to load up when you boot up your computer. Then, your RAM will be able to access your games, apps, and files after it has loaded your files. RAM can access anything from the storage device randomly thanks to this relationship between the storage device and RAM.

Consequently, bigger RAM means faster access to your drive’s components. Imagine that your storage device (HDD, SSD, etc.) is your desk, and your storage device (HDD, SSD, etc.) is your drawers, cabinets, and shelves.

Accessing work files and other items is easy from your desk. In order to retrieve what you have in your cabinets and shelves, you’ll need to get up and rummage through them. You will be able to get down to business much sooner if you have the files on your desk.

Which Matters Most? Size, Latency, or Clock Speed?

In our discussion above, we mentioned size as the most important factor to consider when purchasing RAM.

A PC with 8GB of RAM is a great choice if you plan to use it for email, Microsoft Office, and Netflix. You should have 16GB of RAM if you want to play games, make graphics, produce video, render, etc.

So, Clock Speed Doesn’t Matter?

Most people think it matters a lot, but it doesn’t. You can build an excellent gaming rig using 16GB 2666MHz DDR4 RAM. In spite of its slower speed, most people will not be able to tell the difference between this and 16GB 3200MHz DDR4 RAM.

Using a RAM stick with lower clock speeds is a good option if you’re building a PC for personal or basic business use. Your apps will run smoothly and you’ll save money.

The RAM that you choose should have a high clock speed if you plan on performing graphically intensive tasks such as playing HD games, editing videos, rendering, etc. To help you understand how different clock speeds differ, we’ve created a RAM comparison below.

DDR4 2400MHz vs. DDR4 2666MHz

With an AMD build, you’ll get a little more performance out of a DDR4 2666MHz RAM than a 2400MHz RAM. When playing CPU-intensive games, gamers will likely experience a small improvement in frame rates. If there is a price difference between 2666MHz and 2400MHz, we recommend switching.

 DDR4 2400MHz vs. DDR4 3000MHz

Despite the relatively small speed difference, you will notice a greater change between these two than when switching to 2666MHz. Generally, you’ll notice about a 10 percent increase in performance if the 3000MHz has a good CL rating and capacity.

DDR4 2400MHz vs. DDR4 3200MHz

3200MHz is one of the most popular frequencies among manufacturers. A great CL rating and mid-range CPU motherboards make this RAM an excellent choice. We recommend choosing the 3200MHz if you are able, even though the 2400MHz is fine for budget builds.

 DDR4 2400MHz vs. DDR4 3600MHz

Suitable for high-end CPUs, the 3600MHz RAM operates at 3600MHz. You’ll be able to enjoy smoother processing because it won’t slow down your CPU. You can, however, get by with the 2400MHz if your budget is tight. As long as you have 16GB or more RAM, you should be good.

 DDR4 2666MHz vs. DDR4 2667MHz

The 2666MHz and 2667MHz do not differ much from each other. As long as both have the same capacity and latency, go for the cheaper ones if you are considering buying one of these two.

 DDR4 2666MHz vs. DDR4 2933MHz

When you swap the 2666MHz for the 2933MHz, you may notice some improvement in FPS when you play CPU-intensive games. Generally, however, there won’t be much difference between the two. If you’re on a budget, we recommend working with the 2666MHz, while if you’re looking for more performance, choose the 3000MHz.

 Comparing 2666MHz and 3000MHz DDR4

2666MHz and 3000MHz RAM have similar speeds, so the difference isn’t significant. If you’re concerned about gaming FPS or if there isn’t a huge price difference between both RAMs, then we suggest you go with 3000 DDR4 RAM. We recommend higher speeds to gamers looking to maximize their FPS.

 The difference between DDR4 2666MHz and DDR4 3200MHz

It is noticeable that 2666 RAM differs from 3200 RAM. Swap the 2666MHz for the 3200MHz and you’re sure to notice a speed boost. You may even gain more FPS in games that use a lot of CPU. You may also notice some improvements in certain runtime processes if you are using a high-end AMD Ryzen chip.

 In comparison to DDR4 3000MHz, 2933MHz is faster

It is impossible to distinguish between these two sticks. It is unlikely that most builders will notice a difference between the two. If the latency is equal, choose the one with the better latency or the one with the cheaper price.

 In comparison, DDR4 3000MHz is faster than DDR4 3200MHz

Although you’ll notice a slight improvement with 3200MHz, the speed difference will not result in more than a few additional frames per second in CPU-intensive games. Our recommendation would be to go with the cheaper option if the specs are the same.

 The difference between DDR4 3000MHz and DDR4 3600MHz

There is a 10 percent price difference between 3000MHz and 3600MHz RAM, but the latter offers a 20 percent speed advantage.

It’s recommended that you choose 3600MHz if you’re using a high-end CPU, especially one from AMD. The reason for this is that lower frequencies tend to bottleneck high-end CPUs. In most cases, 3000MHz will be sufficient for most people.

 The difference between DDR4 3000MHz and DDR4 4000MHz

With a 4000MHz stick with excellent specifications, you’ll see a significant increase in performance.

Does it really make a difference in price?

If you plan to edit, render, and produce high-end content, then yes, it is worthwhile.

A four-fold increase in FPS is possible with the 4000MHz over the 3000MHz when gaming. In spite of this nice improvement, if you want to increase your FPS only, you might not want to buy the 4000MHz. You should consider 3000MHz RAM if you intend to build a mid-range or budget PC.

 Compared to DDR4 4400MHz, DDR4 3000MHz is faster

A 4400MHz radio has nearly half the frequency of a 3000MHz radio, giving it a noticeable advantage over the latter. For many game titles, performance will increase by five percent or more. It is however in rendering and video editing that the 4400MHz really shines.

It is really a matter of whether it is worth it for gamers. Definitely, but only if you’re building a gaming rig with a powerful processor. Budget and midrange builds can’t handle the 4400MHz. When building a budget or midrange PC, we recommend the 4000MHz or 3600MHz.

Final thoughts on is ddr4 2666 ram good?

The debate between 2666 and 3000 RAM has raised many concerns. Consider these important points before choosing either RAM stick:

Clock speed is another name for the frequency of RAM

The clock speed of RAM refers to the rate at which its memory can be accessed

When a RAM recognizes a command, its CAS latency is the amount of time it takes

There are four numbers that represent latency. The first number in the string determines the CAS latency of a RAM. When buying RAM, it is important to consider the RAM size, which represents the total capacity of the RAM. A RAM with low latency is better than one with high latency.

It isn’t significant how much RAM is in 2666 versus 3000. Low clock speeds are fine for a PC designed for everyday use. RAM with high clock speeds is recommended for PCs that perform intensive tasks. It is more important to take note of the differences between latency ratings than clock speed differences.

After reading this article, we are confident that you have a better understanding of the factors you should consider when choosing memory for your PC. RAM is a crucial component of a PC you want to build, so it will depend on what you want to build. If you are looking for a balance between latency and speed, we recommend looking at anything from 16GB upwards. The latency rating should be at least CL14 if you’re not sure what direction to go in, and CL16 if you’re not sure what direction to go.
