Best ddr4 ram clock speed

Best ddr4 ram clock speed

The Best ddr4 ram clock speed is that which is suitable for your motherboard. While the base speed of DDR4 RAM modules is 2400 MHz, the manufacturers can overclock that to speeds as high as 4800 MHz. Nonetheless, each of the processors have their sweet spot.

What is a good DDR4 RAM speed?

If you’re considering DDR4 memory, you want to make sure it runs at or near 2,400MHz—or 2400MT/s as it will be displayed on the packaging and online. A user buying DDR3 RAM should look for memory that operates at a speed of at least 1,866MHz and as close to 2,000MHz as possible. Most of the DDR4 are capable of offering such speeds. All the top non-RGB RAMs we discussed offers this too.

Is 3,200MHz RAM good?

AMD Ryzen systems usually run on 3200MHz RAM, but that is likely overkill for Intel systems because Ryzen is more dependent on RAM speed. Who knows. More important may be the amount of RAM. A speed of 3200MHz will work very well with 8-16GB of RAM.

Is higher clock speed RAM better?

RAM is generally related to processing speed, so the faster it is, the faster the processing speed. Memory transfers information to other components more quickly when the RAM is faster. In other words, your computer now runs much faster since your processor can talk to the other components at the same rate.

What RAM Speed Do I Need?

You need the Best ddr4 ram clock speed you motherboard can handle. The speeds of RAM modules are expressed in MHz or Mbps. But what is the best RAM speed? Would it be worth it to have faster RAM?

You have to keep track of many numbers and specs when shopping for any piece of computer hardware. RAM’s speed may appear on the specification sheet.

When RAM speeds range anywhere from 2133 MHz to as high as 4800 MHz, how do you choose the right one? Also, does the speed of your RAM matter?

What Is RAM Speed?

First, let’s clarify what RAM speed is – what is it?

Here, when we refer to “speed,” we’re referring to “clock speed,” just like for the CPU or the GPU. One Hz equates to one clock cycle per second and can be expressed both in MHz and GHz (usually the former).

These are, however, memory modules instead of processors, so the situation is different. Unlike the CPU, GPU, SSD, HDD, or external storage, RAM does not process data, but only transfers it between components.

As a result, RAM speed can be equated to bandwidth. RAM can transfer a greater amount of data when the clock speed is high.

Why Does RAM Speed Matter?

RAM Speed and Its Importance

With RAM clock speed being essentially bandwidth, having a higher clock speed becomes fairly obvious. The system mustn’t slow down because of a RAM bottleneck, which is referred to as the RAM is unable to transfer data at a fast enough rate to keep up with the other components.

So what is the best way to determine the appropriate RAM clock speed without worrying about under- and over-spending on RAM?

It is easy to determine which RAM speeds are supported by the CPU and motherboard by simply looking at the CPU and motherboard’s RAM speeds. The system may behave unpredictably if the clock speed is lower than the motherboard’s minimum requirement; either it will perform poorly, or it might not boot up at all. Whatever the case may be, meeting the motherboard’s and CPU’s minimum specifications should be your top priority when choosing new RAM modules.

High-speed processors can boost performance if you’re running professional applications requiring tons of RAM, but if you’re building a gaming computer, then the minimum will be the most cost-effective option. Those benefits will be more or less insignificant beyond a certain threshold.

  What Does RAM Speed Do?

How does RAM speed affect performance? It is a tricky subject that depends not just on the MHz clock speed, but on several factors. We must consider both the CAS latency and the clock speed simultaneously to get a feel for our RAM’s speed.


RAM Frequency (MHz)

In RAM, clock cycles are used to determine the frequency (although this is only one part of the equation for speed). Every read and every write occurs on a clock cycle. The speed of RAM is measured by the number of clock cycles it can process in a second. According to this calculation, a RAM rated at 3200 MHz will perform 3.2 billion cycles per second.

A RAM with more cycles per second will be able to store and read more data – making user experiences smoother. The number of clock cycles supported by each module correlates directly to the DDR (Double Data Rate) RAM. Comparison of DDR3, DDR4, and upcoming DDR5 (due in 2021) illustrates this point clearly.

CAS Latency

In column access strobe systems or CAS, latency is the delay between a command being received by your RAM and its execution. 15-17-17-35 will be the timings. RAM responses to a command take a certain number of clock cycles. Regardless of frequency, slower CAS timing in faster MHz RAM might be slower than faster CAS timing in slower MHz RAM.

Let’s simplify the information a little more since this could be confusing.

Finding Your Real RAM Speed

A handy little formula has been created for determining the actual speed of your RAM. Let’s examine the different factors to take into consideration when determining your RAM speed before showing you the formula.

As an example, let’s take 3200Mhz as the RAM clock speed.

Next, you should consider how much RAM you have. In DDR (Double Data Rate) for example, the data is transferred on both sides of the clock cycle. In other words, the data is transferred twice during one clock cycle.

The last of the four numbers that make up the RAM timing is the CL Timing, which is the first of the four numbers. In this example, we’ll use (14-15-15-39).


Let’s use an equation to determine the exact speed of RAM based on those factors.


Converting Clock Speed Into Time

time =14*(1/(3200000000/2))

=0.0000000088 sec

= 8.8 nanoseconds

Does RAM Speed Improve Performance?


Is it true that higher RAM clock speeds lead to improved performance? Perhaps, but it isn’t clear at this point.

Gaming involves the amount of RAM used by the game, which is mainly dependent on the game itself. When it comes to gaming, capacity is more important than speed. Therefore, if a game can indeed benefit from a faster RAM clock speed, the performance boost will be limited to a couple of frames you could easily do without. To get the best value for your money, you should pay attention to the GPU.

In other words, if you are watching your budget, don’t go overboard with RAM. There is no tangible benefit to this, and it is probably better to spend that money on a better processor or GPU instead.


A DDR4 memory module’s maximum clock speed by default is 2400 MHz. RAM that is rated higher means that the module was overclocked by the manufacturer to that speed.

It is necessary to enable the RAM’s XMP/DOCP profile before you can access the RAM’s boosted clock speed.

To increase the RAM’s speed to its advertised rate, the motherboard’s BIOS must enable a separate module called an XMP or extreme memory profile. The RAM will run at a slower speed of 2400MHz if you do not select its XMP/DOCP in the BIOS.

Additionally, it’s always a good idea to have all of your hardware working together as a group.


Do I Need The Fastest RAM Speed?

You should not confuse the best ddr4 ram clock speed with the fastest RAM. So do you need the fastest RAM? In most cases, the answer is no. As an alternative, there are sweet spots that you should think about that largely depend on the CPU in your system. In some games, RAM kits with tighter timings improved FPS somewhat, but not as much as a GPU upgrade, which is worth noting. It doesn’t matter whether you go with an AMD or Intel processor, memory kits in the range of 3200MHz to 3600MHz are the most suitable.


It seems that 4000MHz RAM could be worth the investment when it comes to the highly popular Ryzen 5000 series processors. Best RAM for Ryzen  9 3900x hardly exceeds 3600 MHz.  You can expect to pay a lot more for that RAM because of its speed, particularly if you choose a kit with tight timings.

Final thoughts on the best ddr4 clock speed

So, now the big question – what is the best RAM speed to buy?

There are several factors to take into consideration, I suppose. Graphic cards are one of the most significant components that influence frame rates in gaming. This determines whether or not you’ll get more than 140 frames per second in AAA titles. Besides determining what resolution and settings you can use, it also determines how much power you’ll have. According to the above data, it is critical to get the right RAM kit
