How RAM Speed Works?

Here, we’ve summarized the most important points from this essay and presented them in bullet-point form for your convenience. If you’re wanting to improve your gaming experience, these are essentials to keep in mind while getting new RAM:

  • For the most part, we identified a correlation between faster times and tighter timings. You can increase FPS by a factor of 10 or more by reducing the amount of time it takes to complete a task. In the end, I believe you’d be better off spending the extra money on a more powerful graphics card. If you already have a high-end graphics card, this is a great method to get even more performance out of your system.
  • Buying a 3200MHz kit and adjusting the timings all the way down is the best strategy to enhance in-game performance (from RAM), according to our findings. Choosing 3200MHz instead of 3600MHz will save you money, but the difference in performance isn’t that great after tuning in the timings.
  • For those who don’t plan on fooling about with the timings, we recommend purchasing the cheapest 3000MHz+ RAM you can find, and then utilizing it straight out of the box. Out-of-the-box speeds had a very small impact on game performance (less than 1% in most situations), according to all of the research.

What Is RAM?

Your processor’s temporary data store is called Random Access Memory (RAM) (CPU). As soon as you start a program, the hard drive transfers the necessary data to the RAM, where the CPU can access it considerably more quickly than the hard disk itself.

How Does RAM Work?

Every single transistor and capacitor on a Random Access Memory device contributes to its performance and reliability. Each cell is made up of a pair of transistors and capacitors, and the data is stored in these cells.

Using electrical charges to write, rewrite, and erase data, these cells are used. Data can be updated much more often than on a standard mechanical drive (HDD), which relies on platters and actuator arms to move platters around. Even SSDs can’t match the RAM’s speed.

RAM is also “volatile,” which means that if the power goes out, any data stored in its cells will be gone. Consequently, our RAM modules are not permanently written.

In a Random-Access Memory (RAM), data can be written to any cell in any order, and can be read from any cell as long as the physical location of that cell is known.

What Does RAM Speed Do?

So, what effect does the speed of the RAM have? There are several aspects that contribute to the speed of RAM, and the MHz clock speed is just one of them. To gain a true idea of how quick our RAM is, we must take into account both the CAS delay and the clock speed. ‘

RAM Frequency (MHz)

Clock cycles are the basis for RAM frequency (people often call this the RAM speed even though it is only part of the speed equation). The process of reading and writing is cyclical. The speed of a computer’s RAM is measured in cycles per second. If the RAM is clocked at 3200 MHz, it performs 3.2 billion cycles per second.

The more cycles your RAM performs per second, the more data can be stored and accessed, resulting in a better user experience. The higher the DDR (Double Data Rate) RAM, the more clock cycles can be accommodated by the modules. Comparing DDR3, DDR4, and DDR5 makes this clear.

CAS Latency

CL, or Column Access Strobe (CAS) latency, refers to the lag time between when a command is received by your RAM and when it may be executed. The timings will be 15-17-17-35 with those numbers. When the command is issued, the RAM responds in the number of clock cycles indicated by those numbers. RAM running at higher frequencies, but with lower CAS timings, may be more inefficient than RAM running at lower frequencies, but with higher CAS timings.

The data can get a little muddled here, so let’s try to make it a little clearer.

Finding Your Real RAM Speed

A simple formula has been developed to help you figure out how fast your RAM really is. Let’s take a closer look at the various aspects that should be considered when determining your RAM speed before we reveal the algorithm.

The RAM clock speed is the first thing to consider; as an illustration, let’s use 3200Mhz.

The amount of RAM you have is the next consideration. DDR (Double Data Rate) is an example of a technology that transports data on both sides of the clock cycle. To put it another way, data is transferred two times per cycle.
